Concrete Moisture measurement

Why Concrete Moisture Measurement is Important

Before applying a protective coating or other flooring materials to a concrete slab, it is critical to ensure that the moisture level inside the concrete has decreased to acceptable levels—typically ≤75% Relative Humidity (RH), 3 lbs/1000 sq. ft./24 hours MVER, or ≤5% Moisture Content (MC).

​

If not, moisture can accumulate below the coating or flooring causing discoloration, cupping, buckling, blistering, adhesive failure, and/or mold growth. There are various methods used for concrete moisture measurement. The two most-common methods utilize non-destructive electronic impedance meters (ASTM F2659) or in situ relative humidity probes (ASTM F2170).

​

Proper inspection of the moisture content in concrete before installing a flooring system is a necessary part in quality control and assurance—lowering the chances of a flooring system failure.
