Schlüter-TROBA-PLUS-G  Drainage mat for use over sloped waterproofing layers

Schlüter-TROBA-PLUS-G is a reliable and permanently effective drainage layer for use in horizontal applications over sloped waterproofing layers. It consists of a high impact, studded polyethylene sheet that is covered on one side with a fleece webbing with a mesh size of approx. 2 x 2 mm laminated on one side.

The laminated studded side on which the surface assembly rests acts as a high capacity drainage plane (passive capillary drainage).

As a closed polyethylene mat, TROBA-PLUS-G also protects the waterproofing layer. The closely spaced, truncated, conical studs have an extremely high load bearing capacity. The cavities between the studs and the laminated webbing create a heat and sound insulating air space and protect the waterproofing membrane against harmful thermal stress. This results in an even load distribution over the waterproofing assembly.

Schlüter-TROBA-PLUS 8G raises the screed bed by 8 mm over the entire waterproofing surface.

This effectively bridges minor defects in the sloped waterproofing assembly, such as uneven or elevated spots in the overlap area, where water may back up. Larger uneven areas can be levelled with appropriate mortar prior to installing TROBA-PLUS-G.

1. The load bearing substrate and the waterproofing layer placed on it must be adequately sloped toward and connected to the designated drainage exit. Prior to installing TROBA-PLUS-G, larger uneven areas in the sloped waterproofing assembly should be levelled with an appropriate mortar.
2. Independent of the slope, TROBA-PLUS-G is placed loosely over the waterproofing membrane with the mesh fabric side facing up. Adjoin sections by abutting the edges and overlapping the filter fabric.
3. The surface assembly is installed directly over the placed TROBA-PLUS-G according to current industry standards.
4. Note: We recommend our profile types Schlüter-BARA and Schlüter-DILEX for edging profiles, movement joints and floor-wall transitions.

Note: Natural shifts may occur in paver coverings over loosely installed crushed stone/gravel due to one-sided or corner loads.

Assemblies with a gravel or crushed stone bed exceeding a depth of 5 cm may have a minor bounce. We recommend the use of Schlüter-TROBA to avoid this effect; see product data sheet 7.1.
