Dural Durabase CI++ Matting  

De-coupling membrane for tiled surfaces

Crack-bridging decoupling mat with shearing force protection.  Tiles can be laid once the subsurface can be walked on. Decoupling of problematic subsurfaces.  Protecting against cracks.

The DURABASE CI++ multifunctional matting system, with its 3-layer construction, offers much more than decoupling. With its crack-bridging properties and optimised shearing force protection, it allows new tiles to be laid on old and damaged tiled floors, provided that these are still load-bearing. For fresh screed, tiles can be laid immediately as soon as the screed can be walked on.  Quick and straightforward to install and offering maximum installation reliability, DURABASE CI++ is ideal for renovation projects and for laying on mineral subsurfaces which are not quite dry.

1. Cracks in the subfloorCracks in both existing and new sub floors can be transmitted into new coverings. DURABASE CI++ membrane prevents this happening by absorbing stress from sub floor movement.

 2. Stresses in the subfloorSubfloor stress can occur for many reasons, concrete floors will continue to shrink and expand for long periods of time after installation. Wooden substrates can be affected by moisture in the air. Over recent years the growth in heated flooring has dramatically increased the degree of movement within such floors. This “hot and cold” cycle places great stress on the tiled covering.

3. Damp from the subfloorThe air channels within the design of DURABASE CI++ membrane allow moisture that would be otherwise trapped escape. This controlled “release” prevent s problems within moisture sensitive substrates. This is particularly important when laying onto anhydrite subfloors, residual moisture from the screed itself can collect under the tiles and cause damage to the adhesive layer. Particular attention should be made to the residual moisture in such projects before work commences.

Suitable subsurfaces are:
Cement screed, Calcium sulphate screed (anhydrite screed),
Hot screeds Mastic asphalt screeds, Concrete, Synthetic laminates and coatings, Plywood and chipboard, Wooden floorboards.
