Tanking Membranes for Waterproofing Walls & Floors
Tanking membranes are essential for creating a watertight barrier in areas exposed to high moisture or water pressure, such as wet rooms, basements, bathrooms, and swimming pools. These waterproofing systems are designed to prevent water ingress through walls and floors, protecting buildings from damp, leaks, and structural damage.
Available in both liquid and sheet membrane forms, tanking systems are applied before tiling or finishing surfaces to ensure long-term durability. Whether you're waterproofing a domestic shower or a commercial spa, tanking membranes provide a reliable, professional-grade solution.

Frequently Asked Questions
Q1: What’s the difference between a tanking membrane and a damp-proof membrane?
A: While both protect against moisture, tanking membranes are typically used in areas exposed to direct water contact, like showers and basements, whereas damp-proof membranes handle ground moisture or condensation.
Q2: Can I tile directly onto a tanking membrane?
A: Yes, most tanking membranes—especially liquid systems—are designed to be tiled over once cured, providing a sealed and stable substrate.
