Moisture mitigation systems exist to limit the impact of moisture on installed floors and to reduce the risks of moisture-related problems. Think of it as flooring insurance; the cost up front can offset potential disasters down the road. The purpose of any moisture mitigation system is to limit or eliminate the movement of water vapor into the flooring system. This may include water vapor from exterior sources like ground water, or moisture vapor from a subfloor system itself. Regardless of the source, high moisture levels will move from high concentration areas to low concentration areas until it reaches a state of equilibrium. Interrupting that natural process is the key to preventing moisture-related complications. Any efficient moisture mitigation system may involve a number of elements including: Vapor Retarders, Surface Membranes, Adhesives and Moisture Testing.
