Preprufe® 300R Plus LT & 160R Plus LT membranes are unique composite sheets comprised of a thick HDPE film, a pressure sensitive adhesive designed for installation between 25 °F (-4 °C) and 60 °F (16 °C) and weather resistant protective coating. Designed with Advanced Bond Technology™ and a dual adhesive ZipLap™, Preprufe Plus membranes form a unique, integral bond to poured concrete, preventing both the ingress and lateral migration of water while providing a robust barrier to water, moisture and gas.

Release liner free and designed for efficient, reliable installation, the Preprufe Plus ZipLap allows for an adhesive to adhesive bond at seam overlaps and delivers superior performance for low temperature installations.
