Crack Isolation Matting
A decoupling or crack isolation membrane is the most reliable way to solve many of the problems associated with tiling onto problem substrates like chipboard, anhydrite or gypsum screeds, as well as heated floors. By absorbing stress in the substrate, the tiled surface is allowed to stay in tact. Installing crack matting pemits moisture dispersion from new screeds. CI Mat is also a fully waterproof tanking system.
