C.5 Covering assemblies over waterproofing layers

C.5 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. The passive capillary bonded drainage and 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 thinbed mortar.

C.5 Waterproofing, drainage, load distribution layer, bonded drainage and uncoupling

Concrete slab
Sloped screed

The construction has to be sufficiently sloped (1.5 - 2%) to allow for proper drainage.
Vapour barrier according to DIN 18195.
Insulation

Thickness according to construction requirements.
Waterproofing assembly according to DIN 18195.
Schlüter®-TROBA-PLUS

Passive capillary membrane for the effective drainage of seepage and ventilation. It is important to ensure a drainage channel.
Load distribution layer/screed

Cement screed according to DIN 18560-2 or pervious mortar.
Schlüter®-DITRA-DRAIN

Polyethylene drainage mat installed using the thin-bed method, for bonded drainage, ventilation and uncoupling. It is important to ensure a drainage channel.
Ceramic tiles or natural stone pavers

Installed (including large format) with a waterproof and weather resistant dry set mortar.
