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.

Reemulsified Conductive Adhesive
Moisture under floor tiles, causing failed installation

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.

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 ESD 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.

Are you looking for a floor you can install, despite moisture vapor issues, without installing a moisture barrier?

StaticWorx GroundLock Extreme interlocking vinyl tile can be installed over any subfloor including concrete slabs with vapor issues. Ask your StaticWorx Technical Rep if GroundLock Extreme could be a solution for your moisture problem.
