The Calcium Chloride Moisture Test Kit measures the quantity of moisture passing through on and below grade concrete floors (lbs. of moisture over a 1,000 sq. ft. area during a 24 hour period). The pH Test Kit measures the alkalinity of the concrete. The Carpet and Rug Institute, the Resilient Floor Covering Institute and the Canadian Carpet Institute agree that concrete flooring with a surface alkali content of pH 9 or higher must be corrected. |
