DITRA provides uncoupling through its open rib structure, which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface.

What is the purpose of DITRA matting?

Schluter DITRA Matting is designed for tile and natural stone installations, and 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. The substrate must be even and load bearing.

How does an uncoupling membrane work?

An uncoupling membrane system provides an intermediate substrate between the tile covering and load bearing substrate. … The membrane works by preventing stresses from the substrate being transferred into the tile covering that can cause cracking and delamination of the covering material.
