Sealing/Jointing Tape – Black - Biokil CrownSealing/Jointing Tape

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.

Key Features & Benefits

• Watertight Membrane Sealing: Creates a secure seal between membrane overlaps and perimeter junctions.
• Flexible Application: Conforms to uneven surfaces and detailing areas without compromising adhesion.
• Strong Butyl Adhesive: Long-lasting, pressure-sensitive sealant for reliable performance in damp environments.
• System Compatible: Designed for use with Biokil Crown and Newton System 500 cavity membranes.
• Fast Installation: Peel-and-stick design for easy on-site application with no curing time required.
