The main function of the Floortec uncoupling membrane is to compensate tension from the substrate without transferring the tension to the ceramic flooring above, preventing cracks in the tile. We especially recommend using this membrane in the following cases: floor slabs subject to stress; when you don’t want to place a movement joint on the floor in correspondence with a movement joint in the substrate (simply for aesthetic reasons or because it is located in an inconvenient location in a tile installation); a need to speed up the construction process, given that the membrane allows tile to be installed even when the substrate is not completely cured.

Movement joints are superficial joints (at the floor level), placed in correspondence with the underlying substrate. The superficial joint must be realized in exact correspondence with the joint of the substrate, even just a 5cm difference between the 2 joints can cause tile breakage or tenting (you may hear a “popping” sound). We recommend placing movement joints around areas with a maximum side length of 4 meters (16m2).
