Flooring Installation Delayed For Slab Moisture

Concrete slabs and floors can be excellent subfloor surfaces for tile and other floor coverings but too much moisture in the concrete can cause problems with flooring installations.

Flooring installation delayed for slab moisture.

The fastest way to measure moisture in floors is to use a moisture meter for wood. Without an effective vapor retarder below the slab the flooring material becomes the stopping point for rising moisture setting the stage. The difficulty of course is that if the moisture barrier is compromised in any way moisture from the slab beneath can still damage the flooring or finish. If excessive moisture is present it needs to be addressed.

In terms of new construction the slab should be tested after it has cured and prior to the installation of a floor covering. However flooring manufacturers now market some flooring materials as being moisture resistant some laminates engineered woods bamboo and cork flooring materials identified as moisture resistant can be used successfully on concrete slabs. The use of an electronic concrete moisture meter to determine slab moisture emission is not reliable nor recommended. The manufacturer s literature will specify installation requirements to satisfy the flooring s warranty.

This makes it a reliable option to install over your concrete slab.

These devices can be used to test the moisture content mc of. In an ideal world every slab would be tested for moisture prior to the installation of a floor covering.
