Self-adhered bitumen membranes are specially designed for below-ground waterproofing, providing a secure and effective barrier against moisture in foundation walls, basements, retaining structures, and other subterranean areas.

These membranes are made from modified bitumen with a pressure-sensitive adhesive backing, allowing them to be applied without heat or flame. This makes installation safer, cleaner, and ideal for confined or enclosed spaces where torch-on systems aren’t suitable.

Once applied to a primed surface, the membrane bonds tightly to the substrate, creating a continuous and flexible waterproof layer that resists ground movement, water pressure, and root intrusion. Often used as part of a full tanking system, self-adhered membranes help protect structures from rising damp, lateral moisture, and water ingress in challenging below-grade environments.

If you’re building below ground, this system offers a reliable, low-risk waterproofing solution with proven long-term performance.
