Ditra mat a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration and an anchoring fleece laminated to its underside. Designed for tile and natural stone installations, Schlüter®-DITRA 25 serves as a waterproofing membrane, a vapour pressure equalisation layer to accommodate moisture occurring at the underside of the substrate and an uncoupling layer for problematic substrates.
Summary of functions:
ditra mat or otherwise known as Ditra 25 now uncouples the floor covering from the substrate and neutralises the tensions between the substrate and the tile covering that result from the varying deformations of the materials. Likewise, stress cracks in the substrate are bridged and are, therefore, not transferred to the surface covering.
Schlüter®-DITRA 25 is a waterproof polyethylene membrane with a relatively high vapour diffusion density. Provided the joints, floor to wall transitions and connections to building fixtures are properly installed, Schlüter®-DITRA 25 creates a waterproofing assembly with the tile covering that meets the requirements of the mandatory guideline.
c) Equalisation of vapour pressure
The interconnected air channels between the cavities on the underside of the Schlüter®-DITRA 25 matting remain open. This allows moisture in the substrate to evaporate, therefore neutralizing vapor pressure.
