DPM Butyl Tape – 50MM x 10M

Description Walther Strong DPM Butyl Tape is a high performance 2-in-1 jointing tape, now certified for use with both standard and radon damp proof membranes. It is designed to securely hold DPM sheets in place, creating a continuous damp proof and airtight seal at joints, overlaps, and around service penetrations or protrusions. Made from premium butyl rubber, the tape provides excellent adhesion to all damp proof membranes while remaining flexible enough to conform to uneven or irregular surfaces. This ensures long lasting protection against moisture ingress and maintains the integrity of the membrane, even in demanding construction environments. Ideal for builders, contractors, and installers, Walther Strong DPM Butyl Tape delivers reliable, certified performance for both standard damp proofing and radon protection, helping safeguard buildings from water and gas ingress while ensuring compliance with modern building standards.
