CONCRETE MOISTURE TESTING Costly floor covering repair and replacement can be avoided by testing your concrete and wood substrates prior to the installation process. Excess moisture in concrete will damage most flooring covering products and all manufacturers require their products be installed on a dry substrate. |
Prior to your installation, Master Flooring Inspectors and Consultants can test the substrate for moisture emissions. Concrete floors can be tested using the calcium chloride test; ASTM, Protocol E1907 & F1869 or the relative humidity probe method F2170. The Calcium Chloride Moisture Test ASTM F1869 accurately measures the amount of moisture (in lbs.) coming through the slab over a 1000 sq. ft. area during a 24hr. period. The In-Situ Test Probe measurers the relative humidity levels inside the concrete slab which should not exceed 75%, per ASTM F 2170. When moisture emissions exceeds the manufacturers recommendations, they will usually decline responsibility when a floor discolors, bubbles, delaminates, or shows other moisture related conditions. |
