Butech Anti-Crack Matting

Butech Anti-Crack Matting is an uncoupling sheet that sits between your subfloor and your tiles, acting as a buffer against the lateral movements that can cause tiles to crack or de-bond over time. If your floor is subject to low or medium levels of structural movement – such as in a timber subfloor or a building that experiences seasonal expansion – this matting is a worthwhile investment that can significantly extend the life of your tiled floor.

Many uncoupling membranes, including the Butech Anti-Crack Matting, are compatible with underfloor heating systems, as they help manage the thermal expansion and contraction that can stress a tiled floor. We recommend checking the specific product datasheet or contacting our team at Stoke Tiles to confirm compatibility with your particular heating system before ordering.

The matting adds a small amount of height to your overall floor build-up, which is worth factoring in when planning around door thresholds, skirting boards, and adjoining floor finishes. The sheet is relatively thin, but we recommend consulting the product specification for exact dimensions and discussing any height constraints with your installer before beginning the project.

Butech Anti-Crack Matting is designed to perform on floors subject to low and medium level movements, making it suitable for a range of common subfloors including concrete screeds and timber substrates. It is not intended for substrates experiencing significant structural movement or subsidence, and in those cases a structural remedy should be addressed before tiling begins.

The matting is typically bonded to the prepared subfloor using a suitable Butech tile adhesive, and tiles are then fixed directly onto the matting surface using the same adhesive system. This keeps the installation within the Porcelanosa-recommended Butech ecosystem, ensuring compatibility and performance across all layers of your floor build-up.
