A.8 Structural assemblies installed over gravel/crushed stone beds

In this type of assembly, the area drainage membrane Schlüter®-TROBA serves as a protective separating layer over the waterproofing assembly and protects it from the impression of individual stones. Additionally, the product prevents the formation of “ice concrete” when water freezes on the waterproofing assembly. Schlüter®-TROBA allows for the permanently effective drainage of water that seeps through the open joints between the self supporting pavers. Thanks to the special trapezoid shaped studs, loads are directly transferred to the waterproof substrate.
