Advanced Polyurethane Waterproofing Systems

Drythane coatings are 100% solids (solvent-free) two component Polyurethane & Hybrid Polyurea coating systems that contain no solvents, noxious smells and are non-flammable. They have been formulated specifically as high-performance waterproofing membranes. Applied as a thick film (1.20–2.00 mm), these premium, high-performance products have an expected service life of 30 years and more.
