Decoupling might sound like the latest PR spin on a celebrity break up, but it’s actually a very clever system that can save you time and money when tiling on to a problematic floor. Decoupling systems, sometimes also referred to as uncoupling systems, work by neutralizing the tension between the substrate and the tiles, protecting the floor from any damage that could be caused by issues you can’t see.
It may be possible to get the tiles to stay in place for a short period of time on an uneven surface, but once the adhesive and grout fully dry and the floor begins to get more foot traffic, it is highly likely that the grout or tiles themselves will crack. A decoupling system is placed beneath the tiles to create a smooth and even surface to tile on to, and protect from possible problems like this.
These systems have two or three layers which allow them cope with ongoing problems such as uneven surfaces, cracks and even movement of the substrate. Despite this complex layered system, the matting is often very light and extremely easy to use. The matting can be rolled out on to a number of flooring types, including timber, new screeds and concrete – check the manufacturers instructions to see which substrates each individual decoupling system is suitable for.
Decoupling systems can also be used in the process of waterproofing, or tanking, a wet room. Used with the correct adhesives and sealants, decoupling mats can provide a waterproof layer underneath the tiled floor. Uncoupling mats are also perfect for use with electric underfloor heating systems.
