The Heavy-Duty Fracture-Proof Layer for Problematic Floors
Customize Your Order
Description
A highly rigid decoupling waterproof membrane that is resistant to rotting and is designed for tile and natural stone installations onto problematic substrates including standard floorboards, underfloor heating, gypsum floors, green screeds, metal surfaces, asphalt etc. Suitable for interior and exterior areas and works well in extremely damp conditions.
Key Benefits:
- Prevents movement in floors
- Does away with marineply
- Waterproof
- Vapour management
- Install using a 4mm Square Notched Trowel
- Interior and exterior use
Built for Problem Substrates & Maximum Rigidity
This highly rigid orange membrane is the ultimate problem solver for difficult tiling projects. We have engineered it to neutralize lateral movement stresses between the substrate and the tile, effectively preventing cracks. It allows you to tile directly onto "green" (fresh) screeds, asphalt, and timber without the need for thick, heavy marine plywood.

Your Questions, Answered
Traditionally, tilers used 15-18mm marine plywood to stiffen timber floors to prevent tiles cracking. Brit Crack Matting achieves the same stability by "decoupling" (separating) the tile from the wood. This saves you height (it's much thinner than wood), weight, and the cost of lumber.
Yes. This is a key benefit. The mat features air channels that allow moisture vapour from uncured screed to escape sideways (Vapour Management), meaning you don't have to wait months for the screed to dry before tiling.
Yes, the polyethylene material is waterproof. If you seal the seams between the mats with Brit Waterproofing Tape, it creates a fully watertight floor, making it ideal for wet rooms and bathrooms.
You should apply a 4mm bed of flexible tile adhesive (like BritFlex S1) to the substrate using a 4mm Square Notched Trowel. Ensure the anchoring fleece on the underside is fully embedded in the adhesive.
Yes. It is suitable for Interior and Exterior Use. It is particularly useful for terraces and balconies where thermal expansion (sun/frost) causes significant movement in the substrate.
It is designed for "problematic" substrates that ordinary adhesive can't handle, including floorboards, gypsum floors, green screeds, metal surfaces, and asphalt.
