The matting system for decoupling with a composite sealing action for tiled surfaces With its triple-layer construction, the multifunctional DURABASE CI++ matting system offers so much more than simply decoupling. The crack-bridging properties of the mat and its optimised shear force protection enable new tiles to be laid on old and damaged tiled floors, provided that these are still load-bearing. With freshly laid cement based screed, tiles can be installed on fresh screed as soon as installation process is possible, its fast and simple installation processing and optimal installation reliability and quality make it ideal for renovation projects and for installation on mineral subsurfaces which have not dried out sufficiently. - Tiles can be laid once the subsurface can be walked on - Decoupling of problematic subsurfaces - Protecting against cracks
