Geomembrane SCHLÜTER®-TROBA

Schlüter®-TROBA is a reliable and permanently effective drainage system for use over sloped waterproofing layers. It consists of a perforated, pressure-stabilized studded polyethylene sheet and forms hollow chambers between the waterproofing assembly and the gravel or crushed stone layer. Any water penetrating the tile covering and the screed passes through the perforations to the waterproofing layer, where it runs off freely through the drainage cavities. Schlüter®-TROBA has been tried and tested as a surface drainage system for over 25 years.
