Uncoupling / Decoupling membrane is a barrier placed between the tiles and the substrate ensuring that any movement or cracks are isolated and do not transfer through to the tiles. These anti-crack mats will also provide a 100% waterproof barrier.

Suitable For:

• Wood Or Concrete Floors
• Wetrooms or Commercial Areas
• Underfloor Heating
• Ceramic, Porcelain, Stone or Mosaic Tiles

Why Use A Waterproof Decoupling Membrane?

Building materials expand and contract with changes in temperature.

These materials vary in how much they move and sometimes these differences create cracks or stresses. This can be disastrous to the tiles above and can cause the substrate to expand, leading to cracks in tiles and grout joints, or even cause tiles to de-bond.

Uncoupling / Decoupling matting reduces this risk and will make sure that tiles do not crack.

As the floor moves the fleece will decouple from the waterproof layer of the mat, allowing the floor to move but not the tiles on top of it, preventing cracking.

The fleece layer on the matting provides a protective barrier between your tiled surface and the floor substrate it will also give you a 100% waterproof Barrier.
