Are Polished Concrete Floors Waterproof?

Are Polished Concrete Floors Waterproof?

Absolutely — Polished Concrete Floors are installed using a grind and seal process that gives them a protective, shiny, and reflective surface. This surface is resistant to moisture, and this makes the flooring waterproof and makes it last longer. This is why Polished Concrete Floors is famous in regions that experience rain often.

Having waterproof concrete is more than a safety issue. Long-term exposure to moisture can cause several types of problems. Polished Concrete Floors will be watertight so no water penetrates into the concrete. 

A grind and seal are a critical tool for ensuring that your Polished Concrete Floors do not crack or otherwise become compromised. 

Beyond the densifiers used in the installation process, installers can increase polished concrete’s waterproofing by adding material.

This involves installing two thinner slabs after surface preparation and can lead to even better protection for your floor. Installers lay concrete overlays that function as a foundation. 

Once it has cured, a waterproof membrane goes down before a second slab gets poured.

This second slab—the visible one—gets the densifiers worked into it and undergoes polishing so that the final product looks the way the customer wants it to look.
