Product Description


Schluter-TROBA is a reliable and permanently effective drainage system for use over sloped waterproofing layers. It consists of a pressure-stable polyethylene sheet with perforated studs that form vaultlike cavities between the waterproofing layer and the mortar bed. Any water penetrating the tile covering and the mortar bed passes through the perforations located at the sides of the trapezoid-shaped studs to the sloped waterproofing layer, where it runs off freely through the cavities to the drainage exit.
