Concrete Moisture Mitigation

Slab Testing and Mitigation

Concrete Floor Systems provides complete moisture mitigation services for our clients.
RH Testing

RH Testing

We will test your floor using RH Testing. We use probes that measure the relative humidity within the slab. Whether or not your slab passes depends on the humidity within the slab as well as what type of coating or application will be used on top of the concrete slab.

If Your Floor Passes the Test

We’ll let you know the results and that you’re clear to proceed with your project.

If Your Floor Fails the Test (Don’t Worry)

We will guide you through the process, but you have two options depending on your requirements:

Option 1: Vapor Retarder

We will install a vapor retarder on top of the concrete floor. The vapor retarder will prevent any moisture within the slab from having any negative impact on what you overlay on top of the slab.

Option: 2 Moisture Mitigation Coating

We will coat the floor slab with a coating that prevents moisture from emerging from the surface of the floor. This will also prevent any moisture from damaging whatever you apply to the top of the floor

Why is Moisture Mitigation Necessary Anyway?

Obviously, water is an essential ingredient in the creation of concrete floors. As the wet concrete mix is poured and formed into a slab, the water vapor that is within the slab migrates to the surface of the slab.
The vapor is moving from an area of higher relative humidity (the slab) to an area of lower relative humidity (the surrounding air).
Before applying a coating or covering to a new concrete floor, you must be sure that the floor meets the relative humidity requirements for that particular application.
Mold is just one of the many issues that a concrete floor with high moisture content can cause
If there is too much moisture contained within the slab, the following problems can occur:
  • Mold – a wet concrete floor can seep up into anything that comes in contact with the concrete – including carpets, walls, and moulding. The result can be mold growing on all of these surfaces.
  • Warping / Buckling / Cracking – Wood floors placed on top of the concrete slap can be adversely affected by the moisture and can raise and warp – ruining the wood floor. Tile floors can be affected in a similar way. As the moisture makes its way to the surface of the slab, it can cause the tile to bend and crack.
  • Whitening (Efflorescence) – if you apply a stain that has a high concentration of copper salts to a wet concrete floor, the result can be a whitening of the concrete floor. The water vapor
  • Bubbling / Blistering – Pressure from the rising water vapor can cause bubbling and blistering of coatings that are applied to the concrete floor.
