The waterproofing assembly, designed with a surface slope that meets the requirements of DIN 18531, protects the support structure against the penetration of water.

Schlüter-TROBA-PLUS 8G is installed as a drainage membrane between the waterproofing layer and the load distribution layer (screed) to drain away seepage.

This load distribution layer of cementitious or pervious mortar is installed as a thin layer, using the Schlüter-BEKOTEC-DRAIN system.

The natural stone pavers are embedded in the fresh mortar.
