Schlüter®-TROBA-PLUS /-G | Material | Schlüter-Systems



Schlüter®-TROBA-PLUS consists of a pressure stable polyethylene sheet with unilaterally positioned studs and a polypropylene filter fabric bonded to the studs. Schlüter®-TROBA-PLUS 8G features a fleece webbing made of polyethylene.

The material maintains its shape up to a temperature of + 80°C. Schlüter®-TROBA-PLUS 8 and 8G have a compressive strength of up to 39 t/m2, while Schlüter®-TROBA-PLUS 12 has a compressive strength of up to 30 t/m2. The functional and material characteristics are permanently guaranteed. The material is resistant to ageing and does not rot. Schlüter®-TROBA-PLUS requires no special disposal. Polyethylene is not UV stable in the long term and the product should not be stored in places with prolonged exposure to direct sunlight.

Material properties and areas of application:
Schlüter®-TROBA-PLUS is used primarily in horizontal applications over sloped waterproofing layers. It forms an effective drainage layer between the waterproofing and the screed bed placed above it. Its main areas of application are terraces and balconies, but also include industrial structures, swimming pool decks, washrooms, showers, etc, which have been waterproofed.

The loosely placed Schlüter®-TROBA-PLUS is adequately resistant to mechanical stresses incurred during the installation process, e.g. due to foot traffic and wheelbarrows. The cover assembly may consist of screed with or without tiles or can be a structure of pavers or stones installed over gravel or crushed stone beds (minimum height 5 cm). Assemblies with a gravel or crushed stone bed of less than 5 cm may have a slight bounce. To prevent this, we recommend the installation of Schlüter®-TROBA (see product data sheet 7.1).

Schlüter®-TROBA-PLUS 8G is especially well suited for covering assemblies made of pervious mortar or to install pavers over Schlüter®-TROBA-STELZ-DR with thin-bed mortar support rings.

Any water that penetrates the covering is collected in the stilted drainage area of Schlüter®-TROBA-PLUS where it runs off, under normal gravitational force, toward the designated drainage exit. Thus, permanent saturation of the load distribution layer, due to seepage water, is eliminated.
