Concrete Moisture Problems

Static control floors should never be installed without first testing your concrete slab for possible moisture and alkalinity problems. Up front testing can prevent future problems and shutdowns due to failed flooring installations.

Did you know that the number one cause of ESD flooring installation failures is moisture permeation through concrete slabs from below the sub-floor? Moisture vapor, inside concrete, becomes alkaline - adversely reacting with flooring adhesives and consequently compromising the bond you expect from adhesives. More importantly, this problem is almost always unexpected because it rarely involves ground water, heavy rains or the local water table - so there are no visual predictors. The problem isn't solved by installing drains or water diverters around a building because it isn't the result of weather. It is the result of evaporation of water from far below the surface and the worst problems are where you would expect them the least: desert and arid climates like California, Arizona, Colorado, Utah, Texas and Nevada. But the problem also haunts many other locations so it's always a necessity to learn about moisture and how to test for it before it ruins your new anti static or conductive flooring installation.

And, if you're a flooring professional - you're expected to know about moisture problems because your client certainly doesn't know about it.

This page contains some information and helpful links to help you get up to speed on this problem.

Here's ASTM's own description of a resilient floor:
Resilient Flooring — It would be helpful to start with the definition of this category of flooring products, because this term is becoming more commonly used.

According to F 141, resilient flooring is an organic floor surfacing material made in sheet or tile form or formed in place as a seamless material of which the wearingsurface is non-textile. The resilient floor covering classification by common usage includes, but is not limited to asphalt, cork, linoleum, rubber, vinyl, vinyl composition and polymeric poured seamless floors. Resilient in this sense is used as a commonly accepted term, but does not necessarily define a physical property.
