For successful flooring projects, it is crucial to measure moisture below the surface of the concrete slab. Otherwise, you may end up with warping, buckling, peeling, debonding, mold, or other serious issues. Testing is really quite easy. Just be sure you test for moisture before you install any finished floor product. This minimizes the risk of a catastrophic flooring failure. Floor coverings, adhesives, and other finished floor products should never be used on a slab that isn’t sufficiently dry.
