Moisture Testing

Moisture problems account for approximately more than 80% of all installation failures resulting in more than $1 billion in annual damages. The more porous the material, the greater potential it has for moisture vapor to pass through at a rate that’s harmful for the finish floor covering. There’s a misunderstanding that older slabs are by nature dry, but looking at the technology from years ago to now, there may be more moisture in the slab than we think. Vapor barriers have come a long way and over years can deteriorate underneath the slab. Not only that, who knows if there’s a vapor barrier underneath the slab at all? These are all things that need to be taken into consideration whether you’re doing a remodel, or a new build.

5.1 Moisture Testing—All concrete slabs shall be tested for moisture regardless of age or grade level. For the preferred moisture testing method and limits, consult the written instruc- tions from the floor covering manufacturer, the adhesive manufacturer, the patching/underlayment manufacturer, or combination thereof.

Calcium Chloride Moisture Vapor Emission Rate (MVER)

InSitu probes measure the amount of moisture that is IN the Concrete, CaCl Tests measure the amount of Moisture Vapor that is passing THROUGH the concrete.

 
 

We all need to be proactive when it comes to the proper installation of new floor coverings. Accurate moisture testing is the best defense against any moisture relating flooring issues that could lead to unnecessary downtime of a project by doing something that already should have been done.
