The 10 Signs Of Concrete Cancer – How To Identify Concrete Cancer
Luckily, with concrete cancer, the signs are a good deal more obvious than with people. All you have to do is conduct regular inspections so it doesn’t creep up on you! Here are some of the most notorious signs:
1) Rust: Rust marks will appear and are a sign of Concrete Cancer.
2) Worn Surfaces: Unprotected, porous surfaces lead to water absorption and Concrete Cancer.
3) Cracked / Fractured Concrete: Cracks provide water access to the steel reinforcement, instigating Concrete Cancer and fracturing the concrete, enabling further water penetration. Parts of the concrete crumble away.
4) Moisture Stains and Ponding: Inadequate drainage causes water to settle into the concrete, leading to Concrete Cancer.
5) Failing Control and Expansion Joints: Joints that do not facilitate concrete movement can lead to concrete fracturing and Concrete Cancer.
6) Inadequate Concrete Cover: Steel reinforcement that is too close to the surface makes it easier for water absorption, resulting in Concrete Cancer.
7) Rusted Balustrade Fixings: Rust spreads to the embedded concrete, starting the Concrete Cancer process.
8) Bubbling Paint: Paint that appears to be bubbling, i.e. on soffits, often means Concrete Cancer is present.
9) Hollow Surfaces: Concrete surfaces that seem hollow usually have Concrete Cancer.
10) Exposed Steel Reinforcement: Concrete Cancer causes concrete to break away, exposing the steel reinforcement.
If you look out for these things regularly, notice one of the signs early, and get on top of it, the cost you will pay and damage to your building or structure will be significantly reduced. If you do notice one of these things, you should contact a professional to give a proper diagnosis.

Is It Safe To Buy A Property With Concrete Cancer?
Yes, whoever the long answer is, it is best to avoid a property with existing Concrete Cancer. You don’t want to agree to buy a property that has existing Concrete Cancer or shows signs of Concrete Cancer. Only to realise the full extent of the issue and repair costs after you have purchased the property. It is not uncommon for property owners to try their best to cover Concrete Cancer to avoid repair costs before selling the property.
It will cost you thousands, if not tens of thousands of dollars, to fix. So, the concrete slab probably won’t fall on top of you from above (although it could!), but if it has concrete cancer, there is a large list of reasons why it must be repaired for safety reasons.
When it comes to Concrete Cancer on your floor, it is extremely common and must be repaired before any Floor Levelling product, Flooring System, or Floor Coating is installed. If you fail to make the repairs, it will most likely cause your Floor Levelling, Flooring System, or Coating that you have installed to fail. You will not receive a warranty on any of the products installed, as most companies are not willing to install Magnesite Flooring or concrete affected by Concrete Cancer.
How To Identify Concrete Cancer
Concrete cancer, a structural issue where steel reinforcement within concrete corrodes, can be identified by several telltale signs, including cracking, crumbling, and rust stains. Bubbling concrete, rust spots, and leaks are also indicators of concrete cancer. The project suggests that concrete expanding outwards can be another sign.
Signs of Concrete Cancer:
Cracking and Crumbling: Concrete may exhibit cracks or crumble away, especially around areas where the steel reinforcement is located.
Rust Stains: Rust stains seeping through the concrete surface are a clear indication of steel corrosion, a primary cause of concrete cancer.
Bubbling: Concrete may exhibit bubbling or raised patches, particularly in areas where rust is expanding.
Leaking: Leaks in ceilings, walls, or even the roof can be a sign that the concrete is deteriorating due to concrete cancer. 
What Is Concrete Cancer?
The first thing we need to discuss is the composition of concrete structures. Concrete is a porous material, and when used for construction, reinforcing steel is inserted to bolster its strength. Because concrete is porous, it can absorb water and salt air very easily, which corrodes the steel inside.
This process is what gives a structure to Concrete Cancer. Concrete cancer is when concrete absorbs water and salt air, which rusts the steel within. When steel corrodes, it expands. When it expands, it cracks the concrete.
The alkali-silica reaction, more commonly known as concrete cancer, is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous silica found in many common aggregates, given sufficient moisture
The cracking accelerates the concrete cancer process by exposing more of the steel, which significantly weakens the building. It is called Concrete Cancer because if left untreated, the damage will grow further, faster, and be more severe. So get on top of it early!
How Does Concrete Cancer Occur?
The large, glaringly obvious reason for concrete cancer is moisture in the concrete. Here are some more causes to be aware of for your concrete building or structure:
– Poor waterproofing that allows moisture into the concrete
– Salt air and chlorides if your building or structure is near the ocean or a river
– Building defects
– Humid or rainy weather and general wear and tear
– Poor quality concrete
– The Earth’s foundation is built on shifts and moves, promoting cracks
– Magnesite Flooring can rapidly damage your concrete slab
What Structures Are Most At Risk?
A structure most at risk of concrete cancer is exposed to any or all of the above. However, usually, concrete cancer is prevalent in buildings that are older than 10 years old. That isn’t to say younger buildings aren’t at risk, but if your building is more than 10 years old, you should be hyper-aware of the signs.
Treating concrete cancer is highly, highly recommended to be done by a professional. When you have concrete cancer, the spread of it must be shut down. Otherwise, the structural integrity of the building will be compromised, and you could be facing exorbitant prices to fix it, or even have the entire building destroyed.
It should be noted that most buildings from the 1920s to the 1990s have Magnesite Flooring in the unit. This rapidly increases the speed of concrete cancer and should be removed and fixed ASAP.
Properties closer to the ocean/beaches will also have Concrete Cancer start rapidly, a lot faster than properties that are not near the ocean/beaches. Salt hastens the rusting process, so buildings along the coastline are more susceptible to concrete cancer due to salt in the air.
Is There Magnesite Flooring In Your Property?
If your home was built in the 1920s – 1980s, likely, your home (Especially unit blocks in NSW) could potentially have Magnesite Flooring. Magnesite is present below a flooring system such as carpet. Magnesite is a product used as a noise preventative and a Floor Levelling agent.
Magnesite Flooring absorbs moisture (particularly in areas prone to moisture such as external walls, doorways, around shower recesses, near windows, laundries, etc.) Unfortunately, once Magnesite Flooring absorbs moisture, it starts a chemical reaction that will cause Concrete Cancer over long periods.
Because your Magnesite Flooring was laid 40 – 100 years ago, it has likely absorbed moisture over the many decades that it has been trapped under your flooring system, and it has most likely started to break down and lose its strength, making it an unsuitable Floor Levelling product that it once was, as well as very hollow, which destroys its soundproofing.
The best thing you can do to prevent further damage to your property and the concrete slab is to remove it ASAP. Magnesite Flooring consists of Magnesium Oxychloride, which may contain ASBESTOS.
Since it is a health hazard and a major safety risk in NSW, if you remove your flooring system and find out there is Magnesite under it.
YOU MUST remove your Magnesite Flooring for the safety of you and everyone else in your unit block.
Strata may pay to remove your Magnesite Flooring as it is considered “Common property”. Magnesite Flooring can cause Concrete Cancer, which is a major risk to everyone’s safety as well as the successful reinstallation of your new flooring system.
NO company will give you any form of warranty or insurance on any flooring installation job on a magnesite floor, which is another reason why it should always be removed.
How Long Does Concrete Cancer Repairs Take?
Concrete Cancer Repairs can take anywhere from a day or two for minor repairs to several days or even weeks for more extensive cases. The duration depends on the severity and size of the affected area, as well as the chosen repair method. For example, smaller repairs may be completed in a day or two, while larger projects could take several weeks.

Is It Dangerous To Repair Concrete Cancer?
Yes, Concrete Cancer Repairs are dangerous.
Concrete Cancer Repairs without the correct PPE and power tools/equipment will create a harmful silica dust environment. It’s also possible to be injured by tools as well as injured from the Concrete Cancer Repair process.
– SERIOUS INJURIES: Sometimes, Tiny pieces of Concrete can go flying in the air during the Concrete Cancer Repair process. Pieces of concrete can accidentally hit your eye, causing serious damage, if not blindness. The tools required to perform this task are also dangerous to use for people who are not highly skilled in using these tools.
– ACCIDENTAL INJURIES: It’s easy to look up a guide on what tools to use, but injuries often occur from a lack of knowledge of how to use these tools safely.
– PERMANENT LUNG DAMAGE: Inhaling dangerous silica dust by not using the correct PPE and Dust Extractors can be deadly.
The longer silicosis goes without treatment, the more likely it is to develop a complication. Because the disease affects the immune system, silicosis patients are vulnerable to developing tuberculosis, lung cancer, COPD, and kidney disease.
-
- Lung Cancer.
- Chronic Obstructive Pulmonary Disease (COPD)
- Kidney Disease.
- Autoimmune Disease.
Breathing in very small (“respirable”) crystalline silica particles causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.

How Do I Work Out How Much My Job Will Cost?
How To Use A Square Metre Calculator – A square metre calculator is very simple to use. To calculate square meters, you need to know the length and width of each area (Floor plans or manual measuring can help with this). This is also referred to as the area of the shape; most commonly, it’s a simple square or rectangle, but for more advanced areas, it can be harder and different shapes.
Square metres are calculated by Length x Width
For example 1 x 1 = 1 square metre
For example 7 x 4 = 28 square metres
For example 14 x 1 = 14 Square Metres
Or you can simply email Carpet Removal Sydney your “Floor Plan” to make it easier for you. We will calculate the square metres for you, but sometimes a Floor Plan may be missing measurements (most commonly the hallways), so those may need to be manually measured, or we may need to “guess” the rough measurement of that area.
Here is an example of a floor plan sent to us with “Missing Measurements.”
How to Calculate Square Meters
You might find yourself needing the area of a room or other space in square meters for a flooring, renovation, or landscaping project. To obtain such a measurement, you can measure the area of the space in square meters in a few simple steps. Follow along to learn how to calculate it yourself, or simply use the calculator above.
Step One: Measure Length and Width
In order to calculate the area of a space, you must know its dimensions. For example, if the shape of the space is a square or rectangle, then start by measuring the length and width of the space in meters using a tape measure or other measuring tool.
If your measurements are in another unit of measure, centimetres, for example, then you can either convert them to meters first, or you can find the area in another unit and convert them to square meters. We have some simple area conversion utilities, or you can convert yourself. If your length measurements are in centimetres, then divide by 100 to get meters.
If your area measurement is in square centimetres, then divide by 10,000 to get square meters.
If your space is not a square or rectangle, you may need to use a formula to calculate the area of a different shape. Or continue reading to see how to measure the area of oddly shaped rooms.
Step Two: Multiply Measurements Together
Once you have your measurements in meters, you can use the appropriate formula to calculate the area of the space in square meters. Continuing the example above for the square or rectangular room, now that you have a length and width measurement, you can find the area in square meters by multiplying the length and width together.
square meters = length × width
Measuring Oddly Shaped Rooms
Often, you’ll need to measure a space that’s not a perfect rectangle. It might be easiest to try to split up oddly shaped areas into separate shapes and measure the square meters of each of them separately.
Once that is complete, add up the individually calculated areas to find the total area of the space. You’ll also find that the formula above works great for rectangular areas. For other shapes, try our area calculator.
For example, see the formula below to see how to add two individually calculated areas of a complex space together.
total square meters = area 1 + area 2
FAQ’s
Are Square Metres and Metres The Same Thing?
No, square meters are a two-dimensional unit of area, whereas meters are a one-dimensional unit of length.
What Does 1 Square Metre Look Like?
One square meter is equal to a square that is 1 meter in width by 1 meter in height. For visual reference, a guitar is about 1 meter in length, so 1 square meter is approximately the area inside of a square made with guitars for edges.
Are Square Metres and Metres The Same Thing?
You can use square meters anytime you wish to know the area of space. Square meters are typically used for flooring, landscaping, and agricultural purposes.
How Many Square Metres Is A 10 x 10 Room?
A 10 m x 10 m room has an area of exactly 100 square meters, as shown by:
10 m × 10 m = 100 sq m
How Many Square Metres Is A 9 x 3 Room?
A 9 m x 3 m room has an area of exactly 27 square meters, as shown by:
9 m × 3 m = 127 sq m
What Does “Per Square Metre” Mean?
“Per square meter” is used whenever you are dividing some quantity by a total area, measured in square meters, for instance, to find a unit price. For example, if you want to resurface a 60 square meter lounge room and the total cost is $3,000, then the price per square meter is $50, as shown by:
$3,000 / 60 Square Metres = $50 per square meter
$3,000 divided by 60 Square Metres = $50 / Per Square Metre
Do I Need To Turn Off My Air-con And Fire Alarms?
Yes, while we are repairing your concrete with various tools and different methods, we do try to keep the dust to an absolute minimum. (But Dust still may occur, so you must turn off air conditioning units as well as isolate, switch off and cover your fire alarms as dust will set them off)
Do I Need To Hire A Skip Bin?
No, Other Concrete Cancer Repair contractors and Concrete Cancer Repair companies, regardless of job size, will make you hire a skip bin, which will cost a huge amount ($375 – $1,000+) and will have to sit in your front yard for days while you deal with the annoyance of organising it and the large cost of the whole process.
Here at Concrete Cancer Repairs Sydney, we come in, repair your Concrete Cancer. After repairs, our team will sweep and vacuum your property to clean up any dust!
Then, once we are finished, we will also take all the waste to a local resource management centre for you (Recycling whenever possible), which will be far cheaper than you having to hire a skip bin and dealing with the frustration of that whole process! (On average, our clients save 60% on disposal of waste charges)
What Equipment Does Our Team Use?
This is a small range of the equipment that we use on our projects.
Are Our Concrete Cancer Repair Services Dust-Free?
Will The Job Be 100% Dust-Free?
How do we achieve an almost 90 – 99.99% Dust-Free Concrete Cancer Repair experience for our clients?
Here at Dust-Free Concrete Cancer Repairs Sydney, we specialise in Dust-Free Concrete Cancer Repairs. We employ a specialty system that suctions and removes dust and debris directly from our tools into a powerful commercial dust extractor. Our equipment is powerful, strong, and guaranteed to significantly reduce, or even completely eradicate, the dust and debris that is often associated with Dust-Free Concrete Cancer Repairs and replacement projects.
Our specially designed dust-free equipment makes the Concrete Cancer Repair process much faster than traditional Concrete Cancer Repairs. It is also more efficient than traditional removal techniques and is substantially cleaner and safer. This gives our Dust-Free Concrete Cancer Repairs process the added benefit of being the most environmentally friendly solution.
After the Dust-Free Concrete Cancer Repairs process, we will grind your concrete slab with the use of high-powered Dust-Free Concrete Grinding equipment that is connected directly to a high-powered commercial dust extractor. We will also perform demolition services with the use of high-powered commercial dust extraction equipment plugged directly into our tools.
Unfortunately, small amounts of dust are still produced and cannot be eliminated even with the most expensive high-end equipment and the latest technology. It should also be noted that certain equipment, such as Jackhammers, has a harder time trying to contain the dust, even with the use of high-end dust extractors. Concrete Grinders can contain dust a lot more easily. (Roughly 90 – 99.99% of the dust is still sucked up by a 3-engine high-powered commercial dust extractor that is plugged directly into the equipment) But sometimes, a small amount of dust can still escape.
If you are concerned about the small amounts of dust that may get into areas that we are not working in, such as the kitchens, bathrooms, cabinets, etc., we would advise that you seal off those areas that we are not working in with plastic and sticky tape before our team arrives to avoid delays.

Wide cracks in concrete are best patched and sealed with a concrete patching compound. Smaller cracks, less than 1/4 inch wide, can be repaired with a concrete caulk or liquid filler, or Epoxy Injections to Repair Cracked Concrete.
Patching compounds are typically mixed with water and applied with a trowel. They have a texture similar to grout and can be smoothed and textured to blend with the surrounding area. However, the colour of the patch will look like new concrete and will not match the old concrete. Hiding the patch completely requires painting the surface with appropriate concrete paint.

10) Exposed Steel Reinforcement: Concrete Cancer causes concrete to break away,y exposing the steel reinforcement.
Concrete Cancer Caused By Magnesite Flooring
When Magnesite Flooring is exposed to moisture over prolonged periods of time, chloride ions from the Magnesite Flooring diffuse into the pores of the underlying concrete slab eventually reaching the reinforcing steel.
As chloride levels in the slab reach the chloride threshold, corrosion of the steel reinforcement will begin to take place, the longer the exposure time to the moisture source, the more aggressive the corrosion of the steel reinforcement. Corrosion of this nature results in the pitting of the steel reinforcement where it loses its cross-sectional area and strength.
Iron oxide deposits also occur, causing expansive forces within the concrete. These forces cause cracking and Spalling Of Concrete around the corroding steel, a common name for this type of Concrete Spalling is Concrete Cancer.
Signs of Concrete Spalling were noted throughout various units in manly when Carpet Removal Sydney was on a commercial job site doing a strata Magnesite Flooring job. Concrete Cancer had been caused by water leaking from various sources, saturating the Magnesite Flooring for prolonged periods of time.
Magnesite Flooring can be removed with specialized equipment by our Magnesite Flooring removal specialist team. leaving the concrete slab in a condition that is ready to have new flooring installed on.
Although sometimes some Magnesite Flooring jobs will have Magnesite residue stuck to the floor even after the Magnesite Flooring has been jackhammered off. When this happens the remaining residue will need to be ground off using specialized equipment to restore your concrete slab back to a level, smooth state allowing a new flooring system to be installed or to allow the fresh concrete slab to be used as your new floor.
Concrete Cancer is often caused by Magnesite Flooring, Our team are Australia’s leading experts in the removal of Magnesite Flooring. Magnesite Flooring should always be removed for your safety as it can contain asbestos and often causes Concrete Cancer.

What Is Concrete Cancer?
Concrete Cancer is the term given to the process where rusting structural steel begins to rust and in doing so expands, creating stresses and fractures in the surrounding concrete. Because concrete is porous, it can absorb water and salt air very easily, which corrodes the steel inside.
This process is ongoing if not addressed according to structural engineer specifications. If left to develop, the fracturing concrete allows further areas of moisture penetration in turn leading to the development of larger and more numerous areas of Concrete Cancer.
This process is ongoing if the rusting steel is not correctly addressed and the surfaces are left with no waterproof coating. In time, initial small areas of Concrete Cancer become larger and more expensive to repair. In our experience this equates to growth in the damage of approximately 5% per year, directly impacting repair costs.
Concrete Cancer, cracked or damaged concrete is much more than just an eyesore. Left untreated, compromised concrete can quickly lead to serious structural problems requiring extensive remediation.
Concrete Cancer occurs when carbonation and high chloride levels in the environment (usually present in coastal locations) cause corrosion of concrete buildings. If it’s left untreated Concrete Cancer can lead to serious structural deterioration resulting in extensive and expensive repairs.
The expert Concrete Spalling Repair and waterproofing solutions from our team are an efficient and cost-efficient way of addressing Concrete Cancer and concrete cracks.
Concrete Cancer is a term used to describe the degradation of concrete structures often caused by interstitial contaminants in the concrete constituents, moisture ingress, and the alkali-silica reaction.
Chloride-contaminated constituents can find their way into concrete structures if sourced from a chloride-rich environment such as a coastal region. Chloride ingress can also be attributed to the structure’s surrounding environment, which is a particularly important issue in Australia.
The presence of free chloride ions in a reinforced concrete structure causes de-passivation of the steel reinforcement bars, allowing them to corrode. As the steel corrodes inside the structure, the reinforcement bars expand, inducing stress on the surrounding concrete and leading to Concrete Cancer.
Once initial cracks form in the Concrete Cancer processes, further degradation is accelerated as there is greater exposure to moisture ingress.
In the alkali-silica reaction, certain concrete constituents in the aggregate react with the alkali to form alkali-silica. This highly hygroscopic compound imbibes moisture from surrounding pores in the concrete structure.
This has the effect of creating a localised expansion in the alkali-silica-rich sites resulting in high internal localised stresses. When the concrete has become damaged by the alkali-silica reaction it can produce a characteristic cracking pattern on the surface with white alkali-silica gel emanating from this network of cracks.
The word Spall in engineering describes the chips or fragments of a material that is broken off a bigger object. The process of Spalling Of Concrete also known as spallation is the surface failure that occurs when a material such as concrete, brick, or limestone is subjected to excess moisture, corrosion, weathering, and much more. Concrete Spalling commonly known as (Concrete Cancer) is an eyesore and has the potential to be an extreme hazard.
What Is The Cause Of Concrete Cancer?
What Is The Cause Of Concrete Cancer? The large, glaringly obvious reason for Concrete Cancer is moisture in the concrete. Here are some more causes to be aware of for your concrete building or structure:
– Poor waterproofing that allows moisture into the concrete
– Salt air and chlorides if your building or structure is near the ocean or near a river
– Building defects can rapidly excel the growth of Concrete Cancer
– Humid or rainy weather and general wear and tear
– Poor quality concrete
– The earth foundation it is built on shifts and moves, promoting cracks
– Flooring systems such as Magnesite Flooring can cause Concrete Cancer.
Can You Repair Concrete Cancer?
Concrete Cancer can start in a number of ways including using poorly treated reinforcing steel when the concrete is poured, having the ends of the reinforcing too close to the surface so that water can get to it, using incompatible metals (this causes a reaction), having fractures in the concrete as well as things such as Magnesite Flooring.
Dealing with Concrete Cancer is not a DIY job. Concrete Cancer will need to be removed via penetrating the concrete enough to reach the rusting steel reinforcement; thoroughly remove the rust; treat the steel, and waterproof the steel to ensure the problem does not occur again. Depending on the severity of the problem, the concrete repairers may use a technique called “crack” injection to create a water diverting membrane or, if the problem is serious, more invasive action may be required.
Just as a disease needs proper diagnosis and appropriate treatment, so does Concrete Cancer. However, there are several telltale signs of its presence that can alert you to the problem. Look for:
– Flaking concrete
– Cracking concrete
– Magnesite Flooring
– Rust stains that appear with no external cause
– Bubbles in concrete render (surface finishes)
– Leaks in a concrete roof or in internal walls
If you suspect Concrete Cancer is developing, call our Concrete Cancer specialist team immediately and let them diagnose and treat the problem. If you catch the problem early, the repair is usually much easier and cheaper than if you put it off and let the problem get worse.
If you suspect that you have Concrete Cancer in any form, it is important that you get treatment as soon as possible otherwise the problems will only get worse. Treatment needs to be done by qualified professionals as poor treatment will only hide and delay the problem.
It is not enough to just render over the concrete to hide the rusting steel, this is commonly done through layers of ardit by “home handymen” or “DIY” people to hide the issues and sell the property. The rusting process will just continue underneath, causing further displacement of the concrete and even necessitating the replacement of the reinforcing steel altogether. Rather, the cause of the Concrete Cancer needs to be appropriately identified before a fix can be applied once the cause is identified repairs can start
Concrete Cancer puts owners of the property at risk of negligence suits. Damage can occur through concrete pieces falling and injuring people, property, or even accidental death. Further, Concrete Cancer that is not attended to in a timely manner will only lead to further costs as the problem spreads.
What Is Concrete Cancer?
Concrete Cancer (also known as Concrete Spalling) is the aggressive rusting of steel reinforcement beams in the concrete slab.
As the steel rusts it expands, displacing the concrete around it, causing it to become brittle and crack thus accelerating the process. Which can be incredibly dangerous to the strength of the structure and flooring.
The alkali–silica reaction, more commonly known as “concrete cancer”, is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous silica found in many common aggregates, given sufficient moisture
Signs of Concrete Cancer include:
– Crazing and cracking concrete (Concrete Spalling)
– Rust stains which seem to leak out from within the concrete
– Bubbling (also called Plating) of concrete render
– Leaks which appear in overhead concrete surfaces
What Causes Concrete Cancer?
Concrete Cancer (also known as Concrete Spalling) is aggressive rusting of steel reinforcement beams in the concrete slab which can be incredibly dangerous to the strength of the structure and flooring.
Sydney’s older apartment developments have a topping of magnesite on concrete flooring that displays a smooth finish. Long-term exposure to moisture that occurs in household kitchens, bathrooms, laundries or balconies as well as windows, can lead to the magnesite releasing harmful chlorides.
Concrete Cancer is a serious problem that occurs within the concrete and it is caused by the steel reinforcing inside the concrete rusting. As the steel reinforcing rusts, it expands, causing the concrete around the steel to be displaced.
As the concrete becomes more displaced, more water gets into the steel, causing more Concrete Cancer (rusting) and the problem gets worse. The expansion of the steel causes the concrete to delaminate and results in Concrete Cancer. Concrete Cancer is where the concrete initially cracks and then starts to break away. While Concrete Cancer looks terrible, it can also be dangerous as pieces of concrete fall off and possibly hit people underneath. Concrete Cancer also weakens the strength of the concrete.

What Is Concrete Spalling Repair?
Concrete Spalling Repair is when a professional team comes in to repair concrete that has become pitted, flaked, or broken up which normally exposes the steel reinforcing beams which will often rust. The most common cause of Concrete Spalling comes from contractors who either add additional water to the concrete as they finish it, or they make the mistake and start to finish the concrete before the concrete bleed water leaves the surface of the concrete.
Concrete Spalling Repair will often need to happen if contractors often use water as a finishing aid in case the concrete starts to harden while they are working on other parts of the slab. The addition of the water softens the upper surface allowing them to provide an attractive finish, but it compromises the strength of the concrete. You always need plenty of finishers on a job so the slab can be finished without adding any water.
Concrete Spalling can also be affected by road salts and deicing fluids only contribute to making the problem even worse because it will allow the water more time to penetrate deeper into the concrete before it freezes.
Portland cement is the glue that holds together the sand and stone in concrete. It’s vital to have the correct amount of Portland cement at the surface because this is where weather attacks concrete and where concrete receives abuse from car and truck tires as well as foot traffic.

Why Do I Need To Repair Concrete Spalling?
Concrete Spalling must be repaired by law to prevent a possible lawsuit for negligence. You are putting yourself as well as the community in danger by ignoring the signs of Concrete Spalling if a piece of concrete falls off your balcony due to Concrete Spalling you could face a lawsuit due to the issue being known but nothing been done about it. Concrete is heavy and could strike someone walking down the path and kill them if it hits them.
Spalling Concrete is a common issue for older buildings. It is largely caused by carbonation, a natural deterioration process. This causes the steel bars embedded in the ceiling slab to corrode, which in turn causes the concrete cover to crack and bulge. As the owner, you are responsible for the repair of any Concrete Cancer in your flat.
Strata committees often try to show a blind eye to Concrete Cancer & Concrete Spalling due to the expensive nature of repairing the issue. But all they are doing is setting themselves up for a recipe for disaster and the cost to repair the Concrete Spalling is only going to increase as the problem gets worse by not acting fast. Huge costs can be avoided by acting quickly when Concrete Spalling is seen.
How We Repair Spalling Concrete
Step 1: Free call out and quote from our Spalling Concrete Repair specialist team
Our Spalling Concrete Repair specialists team will examine the site and identify what’s causing the Concrete Spalling and how we will repair it.
Step 2: Repair the areas effected by Concrete Spalling
All affected concrete is removed along with any associated brick-work. We then get to the structural level where we grind back any reinforcing steel and remove rust. We will then remove any rusted steel if necessary or if safe to do so, treat the steel with anti-corrosive membranes so that the Spalling Concrete Repair service can start to work. We then work to replace any brickwork and restore the original concrete.
Step 3: Apply waterproof membrane to reduce risk of Concrete Spalling
Our Spalling Concrete Repair specialist team will apply a waterproofing membrane. This will keep out the moisture that is one of the causes of Spalling Of Concrete.
How Do I Know When A Concrete Spall Needs To Be Repaired?
It is often quite obvious when a Concrete Spall needs to be repaired as the concrete will start to flake and chip away leaving exposed steel reinforcing beams to get attacked by moisture in the air which will start rusting the beams.
In most cases, Spalled Concrete is caused by poor finishing and the use of water on the surface to aid in the finishing process. Excess water and over finishing create a weak surface that can’t handle freeze-thaw expansion and contraction.
This type of surface failure, known as a Concrete Spall. It is more common in colder climates where freeze-thaw cycles and deicing chemicals are prevalent. Freezing causes the water in the capillaries of the concrete to expand, creating pressure. Over time, the expansive pressure from repeated cycles of freezing and thawing can break away the top surface of the concrete, leaving Concrete Spall.
Deicing chemicals only aggravate the already-stressed concrete by allowing more water to migrate into the concrete, thus increasing the size and depth of the Concrete Spall. That’s why the problem occurred only in front of the garage, where cars are often parked. Deicing chemicals picked up from the road dripped onto the surface, allowing water to permeate that area.
On new concrete, you can dramatically reduce a Concrete Spall by applying a penetrating waterproofing sealer 28 days after concrete placement and every few years thereafter.
What Is Concrete Spalling?
Concrete Spalling, cracked or damaged concrete is much more than just an eyesore. Left untreated, compromised concrete can quickly lead to serious structural problems requiring extensive remediation.
Concrete Spalling occurs when carbonation and high chloride levels in the environment (usually present in coastal locations) causes corrosion of concrete buildings. If it’s left untreated Concrete Spalling can lead to serious structural deterioration resulting in extensive and expensive repairs.

What Causes Concrete Spalling?
Spalling Of Concrete (also known as Concrete Cancer or Concrete Spalling) is aggressive rusting of steel reinforcement beams in the concrete slab
which can be incredibly dangerous to the strength of the structure and flooring.
Spalling Of Concrete will start to damage the concrete and steel reinforcing beams in the concrete slab.
Concrete Spalling Sydney offers a free inspection of the concrete slab to inspect for any Spalling Of Concrete. Which should always be done before installing a new floor topping, especially if you have recently removed a Magnesite Flooring.
Firstly, Spalling Of Concrete is not attractive and makes a structure look uncared for. More seriously, if the structure is in an area accessed by the public, or by workers, then Spalling Of Concrete can be hazardous in terms of falling debris or trip hazards.
If left unchecked then Spalling Of Concrete will tend to accelerate and spread so that, eventually, the structure could become unstable. Diligent maintenance is therefore of great importance and legislation places a duty of care on owners to ensure that structures are not hazardous to users.
There are also serious commercial considerations. If a structure is left to deteriorate then the value of the asset will diminish and, furthermore, maintenance costs will tend to increase as corrosion and Spalling Of Concrete becomes more widespread. For some structures, such as car parks, customers will stay away if the environment is unattractive and potentially hazardous.
Spalling Of Concrete – especially on the outside of a building – not only looks terrible, but it is potentially dangerous too. Over time, and with increased exposure to the elements, untreated pieces of concrete may fall from your structure. The risk is it falling and damaging property, or even worse, hitting a person walking below.
There are a number of reasons your building may have Spalling Of Concrete.
Spalling Of Concrete usually occurs for one of three reasons, or sometimes a combination of these reasons. Salt, particularly the sodium chloride that’s used on frozen roads in many northern states, can result in oxidation or rusting of reinforcing steel when it’s repeatedly introduced to a surface or building.
But Spalling Of Concrete is more likely to occur due to the curing process or the way the concrete hardened. Carbon dioxide in the air and alkalis in the concrete mix can also interact and force cracking that admits water.
Common reasons that your building may have Spalling Of Concrete include:
- A poorly poured substrate which has allowed moisture to seep into it through cracks and voids
- Inadequate preparation of the reinforcing steel when the original concrete was poured
- The ends of the reinforcing beams are too close to the surface. In heavy rains, water may seep through causing lime and other chemicals in the steel to oxidise
- Incompatible metals being used in close proximity to each other, thus causing a reaction which allows water into the slab
- Stress fractures from bearing weight or general wear-and-tear allow water to penetrate the concrete and react with the steel
- Corrosion of embedded reinforcing steel, because the corrosion products (rust) occupy more volume than the original steel, and the resultant pressure spalls the concrete.
- Fire exposure due to which free water in the concrete changes to stem and create internal expansive pressure in concrete, consequently spall off the concrete.
- Freeze and thaw cycling
- Expansive effects of Alkali-Silica Reaction
- Inadequate depth of cover over reinforcement
- Low quality concrete cover over reinforcing steel
- Joint spalls are often caused by improperly constructed joints lead to joint spalling
- Bond failure in two-course construction due to Differences in shrinkage between topping and base courses, drying of the bonding grout before the topping concrete is placed, etc
Spalling Of Concrete breaks away pieces of the concrete surface which often extends to the top layers of reinforcing steel. Spalls may be 150 mm or more in diameter and 25mm or more in-depth, and the occurrence of smaller spalls also possible.
Spalling Of Concrete affects a broad variety of structures including framed buildings, multi-story car parks, bridges, jetties, unit blocks, etc.
Spalling Of Concrete leaves the concrete surface patchy and pitted while exposing aggregate underneath. As soon as Spalling Of Concrete is spotted, it should be properly repaired otherwise it compromises concrete surface integrity and jeopardizes the ultimate capacity of the member. Added to that, Spalling Of Concrete could distort the aesthetic appearance of the structure.
Spalling Of Concrete that occurs in a concrete driveway or sidewalk typically happens because the weather changed during the hardening process or something else occurred to prevent the concrete from finishing its curing. Contractors might make the mistake of adding too much water, but frankly, most don’t make mixing errors. Tearing out the driveway isn’t always necessary to fix Spalling Of Concrete. Sometimes the top layer can be removed and a new layer poured in its place.

Is Concrete Spalling Dangerous?
Concrete Spalling occurs when the steel reinforcement within a concrete slab begins to rust. The rusted steel increases to approximately five times its original size, displacing the concrete and causing it to flake. Once the concrete is flaking more and more damage occurs – as more water can enter the affected area and cause further rusting, thereby speeding up the process and increasing the affected area.
Concrete Spalling is usually caused by corrosion of the steel reinforcement bars embedded in the concrete matrix but can be caused by other ferrous elements either fully or partially embedded in the structure.
Steel frame window systems, handrails, structural I-beams, metal pipes and conduits are among the most common of the damage-causing building components. Corrosion of the reinforcing steel, however, is by far the most common cause of Spalling and splitting in older concrete structures.
Spalling Concrete is a common issue for older buildings. It is largely caused by carbonation, a natural deterioration process. This causes the steel bars embedded in the ceiling slab to corrode, which in turn causes the concrete cover to crack and bulge. As the owner, you are responsible for the repair of any Spalling Concrete in your flat.
Steel reinforcement bar (rebar) is used in concrete to provide strength to the concrete that is extremely high in compressive strength but has very limited flexural or tensile strength.
One of the principles of reinforced concrete is that the high alkaline content of the concrete is meant to aid in protecting the embedded steel from corrosion, for this to happen though there needs to be a minimum amount of coverage on the steel. As a general rule of thumb, one inch of cover is required to protect the steel rebar, in other words, no rebar should be nearer than one inch to the concrete surface.
There are many factors which contribute to the premature deterioration of concrete due to Spalling however the most common causes in the Sydney region include high pollution levels and the local coastal environment coupled with poor construction techniques, which were unfortunately often employed in previous years where less was understood about the true requirements of reinforced concrete construction.
The coastal environment can be particularly destructive to reinforced concrete, particularly if the structure has not been carefully constructed to stringent engineering standards. The reason for this is concrete is a porous material that has the ability to absorb moisture. In the Sydney region, moisture or water is often combined with other elements to produce carbon dioxide-rich saline solution.
Once the concrete has absorbed this solution, the naturally occurring alkalinity within the concrete that protects the reinforcement from corrosion begins to diminish. Over time the alkalinity levels will reduce sufficiently that the reinforcement will no longer be protected within the concrete and will become susceptible to Concrete Spalling.
Concrete Spalling, Concrete Cancer or Spalling can occur in almost any location within a steel-reinforced structure however it is commonly found on the external edges and surfaces of buildings including balconies, concrete slab edges, plus external concrete columns and slab soffits where there is often a lesser thickness of protective concrete covering the steel reinforcement.
Detriment due to Concrete Spalling can be easy to detect however the cause of the damage is not always obvious. Some of the key indicators include cracking or detached concrete, rust staining leaching out of the concrete surface, bulging concrete render and exposed sections of reinforcement in concrete structures.

Our Spalling Concrete Repair specialist team will apply a waterproofing membrane. This will keep out the moisture that is one of the causes of Spalling Of Concrete.
Concrete Spalling On Foundations
Concrete Spalling On Foundations effects a wide variety of structures including concrete framed buildings, multi-story car parks, footpaths bridges, driveways jetties, roofs etc. Which will all need to have the Concrete Spall Repair issue sorted as soon as possible to prevent further damage or serious danger to the public.
Concrete Spalling can have wide-ranging consequences in terms of health and safety, structural integrity and asset value. Unfortunately, a sticking plaster approach is often taken to repairing spalling structures, with the underlying causes left untreated. Concrete Spall Repair must be done properly by a trained and licensed professional team.
Concrete Spalling is a term used to describe areas of concrete that have cracked and delaminated from the substrate. There are a number of reasons why spalling occurs including freeze-thaw cycling, the expansive effects of Alkali-Silica Reaction or exposure to fire.
However, the most common cause of Spalling is the corrosion of embedded steel reinforcement bars or steel sections. Corroding steel can expand up to ten times its original volume, exerting stress on the surrounding concrete which is why it is so important to start the process of Concrete Spalling Repair as soon as you notice it developing.
When steel is cast into concrete, the naturally high alkalinity helps to protect the embedded steel from corrosion. However, the protection afforded by high alkalinity can be compromised by the ingress of acidic atmospheric gases, a process normally referred to as carbonation, or by the presence of salts in the concrete, typically from marine environments or from the use of de-icing salts.
Combine these contaminants with oxygen and water and we have the key ingredients for corrosion. The reason some concrete structures exhibit a widespread need for Concrete Spall Repair whilst others appear to be in a sound condition is down to a combination of age, maintenance, concrete quality, the depth of concrete cover and local environmental conditions.
The use of a suitably qualified contractor is critical for Concrete Spall Repair as is diligent substrate preparation and the selection of a repair material that is compatible with the host concrete. Typically Concrete Spall Repair will be carried out using pre-bagged materials, thus ensuring consistency and compatibility of components. Materials are available for either hand placed, flowable or spray application, normally determined by the size and geometry of the application.

Concrete Spalling In Basements
Efflorescence is evident in many wet basements. You can see it on the walls and it will flake like chalk if you scrape it with a coin. This problem can be fixed by putting in French drains — dig a trench, line it with rocks, drop in a drainpipe, and attach waterproofing sheets of plastic to the walls.
Home sellers often try to mask the evidence of Concrete Spalling or a wet basement by painting the concrete walls with a water-repellent sealer. This is one of several very good reasons to always obtain a professional home inspection to inspect for Concrete Spalling before buying a home. A home inspector might uncover evidence of a wet basement that isn’t always evident to the casual observer.
On the other hand, it doesn’t necessarily mean that the foundation is Spalling just because water might be present in a basement. Some homeowners install and use sump pumps to reduce water levels in the basement and to pump out excess water during a rainstorm.

What Does A Spall In Concrete Look Like?
A Spall In Concrete looks like flakes of material that are broken off of a larger solid body. A Spall In Concrete typically begins when the steel reinforcing embedded within the concrete member rusts. A Spall In Concrete can be as simple as your concrete starting to flake or chip away, or large chunks starting to fall off which reveal the steel reinforcing beams. There are a lot of things to look out for when buying a new property especially close to the ocean if you want to check for a Spall In Concrete you should look for any patchwork that has been done to the concrete slab, driveway, foundation, walls, roof, footpaths, etc.
Here are a few examples of a Spall In Concrete in Sydney from job sites that we have attended:
Why Does Magnesite Flooring Cause Concrete Spalling
Concrete Spalling starts when Magnesite Flooring is exposed to moisture over prolonged periods of time, chloride ions from the magnesite diffuse into the pores of the underlying concrete slab eventually reaching the reinforcing steel.
As chloride levels in the slab reach the chloride threshold, corrosion of the steel reinforcement will begin to take place, the longer the exposure time to the moisture source, the more aggressive the corrosion of the steel reinforcement.
Concrete Spalling caused by Magnesite Flooring, corrosion of this nature results in the pitting of the steel reinforcement where it loses its cross-sectional area and strength.
Iron oxide deposits also occur, causing expansive forces within the concrete. These forces cause cracking and Spalling of the concrete around the corroding steel, a common name for this type of Concrete Spalling is Concrete Cancer.
Signs of Concrete Spalling were noted throughout various units in the northern beaches when Carpet Removal Sydney often do strata Magnesite Flooring Removal jobs. Concrete Spalling had often been caused by water leaking from various sources, saturating the magnesite for prolonged periods of time. As well as living close to the ocean with “common area” windows open leaving hallways with carpet and Magnesite underneath to be exposed to the elements which led to the entire unit block having Concrete Spalling.
Concrete Spalling issues can be treated by our specialist team as well as having Magnesite Flooring removed with specialized equipment by our Magnesite Flooring Removal team.

What Is Spalling?
Salt Spalling In Concrete is a specific type of weathering which occurs in porous building materials, such as brick, natural stone, tiles, and concrete. Dissolved salt is carried through the material in water and crystallizes inside the material near the surface as the water evaporates. As the salt crystals expand this builds up shear stresses which break away from the surface and start Spalls In Concrete.
Concrete Spalling or Spalling is a defect that is administered in a hardened concrete structure, where the concrete is slowly broken down into small flakes known as Spalls from a larger solidified concrete body.
When a concrete structure is exposed to freezing temperatures, the water stored in the capillaries of the concrete solidifies and expands, creating an internal pressure on the top solidified layer. Over time, due to the force applied by freezing and thawing cycles along with the internal pressure of expanded water, the top layer of the concrete tends to chip away leaving pit marks, concrete fragments or Spalls.
The threat of Concrete Spalling can be minimized by preparing the concrete with the appropriate water-cement ratio, air content, and a minimum specified compressive strength, and by proper finishing.
What Will Happen If My Concrete Is Spalling?
Spalling usually occurs for one of three reasons, or sometimes a combination of these reasons. Salt, particularly the sodium chloride that’s used on frozen roads in many northern states, can result in oxidation or rusting of reinforcing steel when it’s repeatedly introduced to a surface or building.
But Spalling is more likely to occur due to the curing process or the way the concrete hardened. Carbon dioxide in the air and alkalis in the concrete mix can also interact and force cracking that admits water.
Spalling can be caused by a poorly poured substrate which has allowed moisture to seep into it through cracks and voids as well as Inadequate preparation of the reinforcing steel when the original concrete was poured.
Concrete Spalling can also be caused when the ends of the reinforcing beams are too close to the surface. In heavy rains, water may seep through causing lime and other chemicals in the steel to oxidize as well as Incompatible metals being used in close proximity to each other, thus causing a reaction that allows water into the slab.
Spalling is also be caused by stress fractures from bearing weight or general wear-and-tear allow water to penetrate the concrete and react with the steel which causes corrosion of embedded reinforcing steel because the corrosion products (rust) occupy more volume than the original steel, and the resultant pressure Spalls The Concrete.
Fire exposure due to which free water in the concrete changes to stem and create internal expansive pressure in concrete, consequently Spall Off Concrete.
Freeze and thaw cycling, expansive effects of Alkali-Silica Reaction, inadequate depth of cover over reinforcement, Low quality concrete cover over reinforcing steel, Joint Spalls are often caused by improperly constructed joints lead to joint spalling can also be a big factor in causing Concrete Cancer.
How Can I Repair Concrete Spalling
Spalling Concrete is the deterioration of concrete due to environmental factors, poor installation, and other reasons. It has the potential to wreak havoc on a concrete structure. So, protecting the concrete early can avoid the dangers and also avoid having to replace it later
Spalling Concrete is caused by water or moisture ingress into a concrete structure, causing the reinforcing steel to corrode or rust. When the reinforcing steel rusts, it expands to up to 700% its original size, causing the surrounding concrete to be displaced.
This displacement can cause cracks, flaking, or in extreme cases, the concrete can fall away from the structure which is a major safety hazard, as well as causing the weakened structural integrity of the structure.
If left untreated, the damaged caused by Spalling Concrete can grow exponentially, as more and more water or moisture is able to enter the structure due to the existing cracks and open cavities caused by Concrete Spalling. This can lead to major and extensive structural and non-structural damage, meaning extensive and expensive repair is required.
Spalling Concrete is also known as Concrete Cancer. It has the capacity to cause serious hazards, public injury, and loss of public property, as it can damage the whole structure, like damage to reinforcing bars within the concrete. Hence, Spalling Concrete is an issue that needs attention. It should never be left exposed or without being treated. It is very important to address Spalling Concrete issues when they begin to occur.
The signs of Spalling Concrete are a chipped and flaky surface, chunks of concrete coming out from the installation, and concrete starting to crack. Their signs may also include marked lines, discolouration, and roughness of the concrete. The best time to address spalling is when concrete is first poured, by taking steps to prevent it from occurring.
One of the main reasons of Spalling Concrete is a natural process called carbonation. Water seeps into the concrete and causes the reinforcement bars and other elements embedded in the concrete to corrode, thereby creating cracks and bulges in the concrete surface. Steel reinforcement bars are used in concrete to provide durability to it. Poor quality steel can also cause Spalling Concrete.
Another reason for Spalling Concrete is water. Rainwater or water from any other external source first makes its way into the capillaries of the concrete. During cold days, water freezes inside the concrete and forms snow or ice, which expands and causes the concrete to break, thus developing cracks on the surface. As this cycle continues, the outer surface continues to undergo Spalling Concrete, resulting in weathering. This is also called freeze-thaw weathering.
De-icing salts and rock salts can also cause Spalling Concrete in the same way as mentioned above. Water containing dissolved salts penetrates the concrete and crystallizes inside it when the water evaporates. The crystals of salt expand in volume which creates stress on the concrete and hence wears away the surface.
High temperatures can also lead to Spalling Concrete. When exposed to extreme temperatures either overtime or all of a sudden, the surface gets much hotter than the concrete underneath. This leads to differential thermal expansion which in turn causes stress between the surfaces. Large masses of concrete begin to separate and develop cracks. Alternatively, the heat may cause the release of water within the concrete.

How Can I Stop Spalling Concrete
Engineers believe that porous building materials can be protected against salt Spalling by treatment with penetrating sealants which are hydrophobic (water repellent) and will penetrate deeply enough to keep water with dissolved salts well away from the surface. Great care and expert advice must be consulted, however, to ensure that any coating is compatible with the substrate in terms of breath-ability (ability to allow the release of vapours from inside while preventing water intrusion), or other serious problems can be created.
Repairing the problem immediately rather than waiting for the problem to get worse will also increase your chances of being able to stop Spalling and prevent future damage from re-occurring.

TESTIMONIALS
“Thanks again boys! really happy with how my shop looks now! i knew ripping out the carpet was the best option, definitely looks a lot better with a clean smooth slab so that i could install a nice hardwood floor”
“I was shocked when I had realised that my daughter had spilled my paint set all over my new carpet in my rental property, had no idea what to do, everything I tried failed, gave Carpet Removal Sydney a quick call and they gave me free advice over the phone, with no charge that actually worked! Thank you so much!”
“You were very professional, well dressed, well mannered and quick. I will recommend your services to our friends. Thanks again!”
“Was completely gobsmacked at the quotes that I got from 3 other company’s on the northern beaches and how outrageously high they were just to remove the carpet in a shop I had recently purchased. So it was such a relief when my friend recommended I try out Carpet Removal Sydney and I ended up saving over $3,000, Thanks again!”
“He has great product knowledge and took the time to thoroughly explain the differences of each carpet in a simple way. He has a very personable manner and is very friendly and polite. He explained the process well provided a competitive quote. He was flexible with the install date (as I had some other trades finishing off work before the carpet could be installed) and worked with me to secure a date that suited both parties. I had an issue with the underlay requirements due to strata laws and Declan was very helpful in helping me source the correct underlay to meet strata requirements. I believe he went over and above his role to assist me. The floors are amazing! I’m extremely happy with the choice and the whole process. Thank you Declan. I hope Carpet Removal Sydney realise what an asset you are to their team. ”
“I had absolutely no idea what to do when we had a pipe burst in our property, but thankfully Carpet Removal Sydney had a 24-hour emergency assistance team that did an absolutely amazing job with the removal of the carpet that had been completely soaked, called them up at 2 am on a Tuesday and they were here within 30minutes. Couldn’t be happier with their services!”
“Can’t argue with cheapest prices, best customer services, and same day service! very impressed!”
“The boys at Carpet Removal Sydney also did an absolutely amazing job with the removal as well as the installation of my carpet as well after it was flooded by my dishwasher overnight. Called them up at 6 pm, they were also there the next day and completed the take up the same day! Really happy with the result.”
“I always recommend Carpet Removal Sydney when a tenant moves out of one of our properties if the carpet needs to be replaced. They always do an amazing job, leave the property clean and save our clients hundreds and sometimes even thousands.”
“Thanks again for your help guys, I really appreciate you coming so far to do such a small job”
“Very impressed with your team members high quality work. You all arrived on time, you did an amazing job finish the removal process and installation process without damaging anything. (My last two experiences with carpet layers from carpet court they both damaged the skirting boards and a piece of furniture) So thanks for giving me faith again that a job can be completed without my property being damaged. And thanks to your team for helping me in such short notice due to my unit having flood damage! Really appreciate everything that you did for me!”
“Excellent service from the team at Carpet Removal Sydney. Will definitely use their services again, was absolutely amazed at how much money I saved going through Carpet Removal Sydney instead of going through Carpet Court.”
“I attempted a carpet removal job my self in my new office only to realise the job was commercially glued down, needless to say as a I.T nerd i had absolutely no chance of removing it haha. I thought i would give a few companys a call to request a quote on how much the removal process would cost… and my god i was shocked at the overwhelming expense of how much commercial carpet removal costs… I was so relieved though when i stumbled across Carpet Removal Sydney (One of my co-workers recently had their team out to remove carpet in a new house they purchased) and was relieved when i finally found a company that was willing to do it for a fair price. I was a little concerned at the start due to their price being so much lower than all of their competitors, but my co-worker re assured me that they had an amazing team. I was quite relieved when the whole process was over and they had done such an amazing job for almost a third of their competitors prices. Thanks again lads! If you ever need a computer fixed hit me up! ”
“The boys at Carpet Removal Sydney went out of their way to help me so much as I wasn’t able to move a lot of the furniture myself as my back isn’t great. I also saved over $400 getting the carpet removed by these guys! Would recommend, thanks again!”
