C.3 Thin covering assemblies over waterproofing layers according to DIN 18195
The sloped support structure is protected against permeating water with a waterproofing assembly that meets the requirements of DIN 18195. Schlüter®-TROBA-PLUS is installed as a drainage membrane between the waterproofing layer and the load distribution layer (screed) to drain away seepage. This load distribution layer is installed as a thin layer, using the damage free and non buckling Schlüter®-BEKOTEC-DRAIN system.
The passive capillary bonded drainage and bonded uncoupling membrane Schlüter®-DITRA-DRAIN is installed in the thin-bed mortar between the screed and the tile covering. This results in the broad ventilation of the top covering, which in turn promotes the quick and even drying/curing of the thin-bed mortar.
