Material

Schluter-TROBA-PLUS consists of a pressure-stable polyethylene sheet with unilaterally positioned studs and a polypropylene filter fabric bonded to the studs.

The material maintains its shape up to a temperature of +176 °F (80 °C). Schluter-TROBA-PLUS has a compressive strength of 8,000 lb/ft2 (39 t/m2). Its functional and material characteristics are permanently guaranteed. The material is resistant to aging and will not rot. Schluter-TROBA-PLUS requires no special disposal.

Schluter-TROBA-PLUS is used primarily in horizontal applications over sloped waterproofing layers. TROBA-PLUS provides an effective drainage layer between the waterproofing layer and the covering assembly above. This system is generally used on balconies and terraces, but its applications also include industrial structures, swimming pool decks, washrooms, showers, etc. (all of which have been waterproofed).

The loosely placed Schluter-TROBA-PLUS is adequately resistant to mechanical stresses incurred during the installation process; i.e., due to foot traffic and wheelbarrows.

The load-distribution layer may consist of a mortar bed with or without a tile covering, or it may be constructed of crushed stone or gravel with a paver or stone covering. It is also possible to apply a covering of soil. Any water that penetrates the covering is collected in the stilted drainage area of Schluter-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.
