Gypsum Concrete is a material used for the underlayment of floors. It can be used in wood frame and concrete construction. It can be used for fire ratings, sound reduction, radiant heating and even floor leveling. Gypsum concrete is a mix of the following: gypsum plaster, Portland cement, sand and water. This has become an ideal cement to use for its cost effectiveness, its proven performance, its toughness and of course the speed of installation. Gypsum concrete can take the place of cast-in place concrete, pre-cast concrete, and plywood sub floors. It can, in fact, be installed in a 25,000 sq. ft in one day!
