USG’s Early Exposure Floor Underlayment

USG’s Leverlock CSD early exposure floor underlayment can be poured up to 60 days before the building’s permanent windows and doors are installed in geographic areas not subject to freezing conditions.Designed for use in buildings with light-gauge steel frame construction, this innovative underlayment product can be applied over corrugated steel decks, giving architects and developers an economical means of designing mid-rise buildings up to 10 stories high. As a result, construction professionals can build higher, lighter and faster. Leverlock underlayment is close to 55 percent lighter than three inches of concrete.This underlayment features compressive strengths from 3,500 to 5,000 psi for durability in demanding applications. It can also withstand the rigors of trade traffic throughout the construction cycle, eliminating the need for any floor patching before the finished floor is installed. In addition, its smooth, monolithic surface enhances worker safety and efficiency.Leverlock CSD early exposure underlayment can be applied at a much lower thickness than poured-in-place concrete, reducing dead load and allowing a greater number of floors for increased rentable/sellable square footage. Its self-sealing technology can eliminate the need to seal the underlayment prior to floor-covering
