Gypcrete Systems

Since the late 1950s, one and a half (1½) inches of cellular lightweight concrete was the accepted solution as an alternate to the code requirement of a second layer of plywood in multi-family housing. However, floor underlayment technology has advanced considerably in recent decades. In the 1980’s, ArtDeck was introduced to a gypsum concrete floor underlayment with strengths equal, or superior to, lightweight cellular concrete. Gypsum Concrete, was also crack resistant, poured at ¾”, and was code compliant. Since that time, ArtDeck has worked continuously to improve the quality of gypsum floor underlayment’s available to the building community.

Gypcrete or gypsum concrete is an elite building material most commonly used as a floor underlayment. It is commonly used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. Chemically it is made up of gypsum plaster, Portland plaster, and sand.
