B.1 Covering assemblies with bonded waterproofing

Schlüter®-DITRA 25 is a waterproofing mat for use with floor coverings made of tiles and pavers. In addition to waterproofing, Schlüter®-DITRA offers a bonded uncoupling function that neutralises the stresses occurring between the substrate and the tile covering due to temperature fluctuations. Thanks to the vapour pressure equalisation function of Schlüter®-DITRA 25, the residual moisture of the substrate (e.g. in green screeds) is safely managed.

Note: Abutting joints and connections to walls and construction fixtures should be covered with the sealing band Schlüter®- KERDI-KEBA. The sealing adhesive Schlüter®-KERDI-COLL should be used for waterproofing the joints.

Capillary layer
Concrete slab
Sloped screed

The construction has to be sufficiently sloped (1.5 - 2%) to allow for proper drainage.
