B.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.

  1. Capillary layer

  2. Concrete slab

  3. Sloped screed

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

  4. Waterproofing assembly according to DIN 18195.

  5. Schlüter®-TROBA-PLUS

    Passive capillary membrane for the effective drainage of seepage and ventilation. It is important to ensure a drainage channel.

  1. Schlüter®-BEKOTEC-DRAIN

    Thin load distribution layer as a system for damage free and functionally safe floating screeds (cement screed CT-C25-F4 or pervious mortar).

  2. 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.

  3. Ceramic tiles or natural stone pavers
