The bottom side of the tape has a highly aggressive pressure sensitive adhesive which is designed to adhere to penetrations, protrusions and GCP waterproofing membranes and accessories. The top side of the tape has a pressure sensitive adhesive, a weather resistant protective coating and a release liner. Concrete is cast directly against the protective white coating of the tape. The specially developed PREPRUFE adhesive layers work together to form a continuous and integral seal to the structure.
