Terrace assembly B.8: Unbonded installation on a gravel or crushed stone layer

Unbonded installation over TROBA in a gravel or crushed stone layer

© Schlueter-Systems

In this assembly, the area drainage membrane Schlüter-TROBA serves as a protection and separating layer over the waterproofing assembly and protects it from the impression of individual gravel pieces.

Additionally, the product prevents the formation of “ice concrete” when water freezes on the waterproofing assembly. It also allows for the permanently effective drainage of water permeating through the open joints between the self-supporting pavers.

Thanks to the special shape of the trapezoid-shaped studs, loads are directly transferred to the waterproof substrate.
