High-Performance Waterproofing Solution
The SL Shower Liner Wall Tanking Membrane is a high-performance thin-layer waterproofing solution, specifically designed for creating fully sealed and watertight surfaces in showers, wet rooms, and other areas exposed to constant moisture.
Manufactured from durable yet flexible polyethylene, this membrane provides reliable long-term protection against water ingress, preventing costly damage to underlying structures.
Suitable for both walls and floors, it serves as an ideal substrate beneath tiles, stone, and other surface finishes.
The membrane’s unique construction features strong multi-directional non-woven composite fibres bonded to both sides, ensuring excellent adhesion with flexible tile adhesives as well as Mapei gum-type rubberised tanking paints.
This dual-surface reinforcement guarantees a secure bond, allowing for fast, efficient installation and long-lasting results.
