Sealing/Jointing Tape – Black - Biokil Crown
Butyl Adhesive Tape for Overlaps and Detailing in Cavity Drain Membrane Systems
Biokil Crown Sealing/Jointing Tape – Black is a high-performance, double-sided butyl adhesive tape designed for joining and sealing overlaps between sheets of cavity drainage membranes. It creates a watertight bond that prevents moisture ingress at membrane joints and detailing points such as wall junctions and service penetrations. Essential for use in internal waterproofing, basement tanking, and damp-proofing systems, the tape ensures full membrane integrity in both vertical and horizontal applications.
