Bostik Waterproof Anti-fracture Uncoupling Membrane (1 Metre)

Bostik Waterproof Anti-fracture Uncoupling Membrane (1 Metre Cut Length)

Protect your tiled surfaces from stress, cracks, and structural movement with the Bostik Waterproof Anti-fracture Uncoupling Membrane. This high-performance Bostik membrane is specifically designed to provide a flexible barrier between your subfloor and tile layer—ideal for ensuring long-lasting, flawless finishes in both domestic and commercial settings.

At just 0.6 mm thick, this advanced decoupling membrane delivers maximum protection with minimal height build-up. It cleverly absorbs movement from the subfloor—working like a one-part Velcro that separates and reattaches as needed—reducing stress on your tiles and preventing fractures before they form.

Whether you're tiling over concrete, screed or timber, this membrane is easy to install and suitable for a wide range of challenging environments, including underfloor heating systems, balconies, wet rooms, and even swimming pools up to 4 metres deep. Its waterproof properties also make it a smart choice for bathrooms, showers and outdoor applications.

The Bostik membrane enables fast-track application, reduces adhesive usage by up to 20%, and delivers a professional-grade finish every time.
