Schlüter-TROBA-PLUS consists of a pressure stable, studded polyethylene sheet that is covered on one side with a polypropylene filter fabric. The material is dimensionally stable up to a temperature range of + 80°C.
TROBA-PLUS 8 has a compressive strength up to 39 t/m², and TROBA-PLUS 12 up to 30 t/m². The functional and material characteristics are permanently guaranteed. The material is resistant to ageing and non-rotting. Cutting waste is non-hazardous. Polyethylene is not UV-stable in the long term; 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 TROBA-PLUS is adequately resistant to mechanical stresses incurred during the installation process, e.g. due to foot traffic and wheelbarrows. The covering 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).
Layers of soil or gravel are equally suitable.
Any water that penetrates the covering is collected in the stilted drainage area of TROBA-PLUS where it runs off, under normal gravitational force, toward the designated drainage exit. This prevents the permanent saturation of the load distribution layer with seepage water.
