Description
Waterproof Decoupling Membrane – Floor & Wall Tile Protection System
Waterproof Decoupling Membrane is a professional 3-ply waterproof floor and wall membrane designed to protect tiled installations from substrate cracking and moisture migration.
Installed beneath thin-set ceramic tiles or flagstones, the membrane acts as both a waterproof barrier and a stress-relieving decoupling layer, improving long-term tile performance in wet and high-movement areas.
Applications
- Bathrooms and domestic wet rooms
- Commercial kitchens
- Public and domestic shower areas
- Balconies and terraces with no living space below
- High-moisture environments (when installed with suitable adhesives)
When used with appropriate adhesives or sealants, the membrane can meet higher moisture stress classifications, including applications such as swimming pool surrounds.
