Abstract: A polyurethane waterproofing membrane composition, method of use, and building product containing such composition. The polyurethane composition, upon cure, exhibits strong adhesion to the construction substrates on which it is applied as well as to concrete cast upon the cured membrane, producing a continuous and fully bonded waterproof system, even though different surfaces and surface textures are presented at the surface-to-surface joinder among various components within a pre-applied waterproofing construction site.
