Excessive moisture in floor slabs after floor covering has been installed can cause floor covering system failures such as debonding, peaking and deterioration of finish flooring and coatings, and microbial growth. Manufacturers of such systems generally require moisture testing to be performed before installation on concrete. Internal relative humidity testing is one such method. Moisture test results indicate the moisture condition of the slab only at the time of the test and in the specific locations tested.
