Frequently asked questions

Area load

Which area loads are recommended for Schlüter®-TROBA? Can the assembly withstand the weight of a vehicle?

Show answer

Since assemblies with Schlüter®-TROBA involve beds of gravel or crushed stone, which are in direct contact with the substrate between the individual stilting points, Schlüter®-TROBA does not limit the area load per se. 

Rather, the maximum load is determined by the covering assembly. All variants of our area drainages are sufficiently stable to withstand mechanical impacts associated with installation, for example access on foot or with a vehicle for material transport.

Floor assemblies

When do I use Schlüter®-TROBA, Schlüter®-TROBA-PLUS or Schlüter®-TROBA-PLUS-G?

Show answer

The Schlüter®-TROBA membrane is used for covering assemblies that involve loose gravel. In contrast, Schlüter®-TROBA-PLUS is designed for screed assemblies and Schlüter®-TROBA-PLUS-G is used in assemblies with single-grain screed/drainage mortars or stilted assemblies.
