Moisture Testing of Concrete Walls and Floors
Excessive moisture in cementitious substrates can cause coatings to fail, and surfaces to be disfigured from stains or efflorescence. Moisture problems can occur in poured-in-place concrete pre-cast, tilt-up, and CMU (concrete masonry units). Methods for determining the moisture content are presented, including relative humidity probes, anhydrous calcium chloride, plastic sheet tests, and a variety of electronic instruments.
