LG-1000 Below Grad Waterproofing Membrane

TechSeal waterproofing membrane is a black, single component cold applied urethane that can be applied to vertical or horizontal surfaces. LG-1000 is tack free in 12-18 hours and fully cured in 2-4 days. It cures to a rubbery membrane with excellent adhesion to concrete and masonry surfaces and is impervious to moisture. The cured membrane has expansion and contraction characteristics that make it an outstanding above or below grade waterproofing system.
