Schlüter-TROBA-STELZ-DR are plastic rings made of non-rotting polyethylene.

The covering joints remain open, which enables the finished covering to drain through the joints of the paver elements to the drainage layer of TROBA PLUS 8G, which is installed over the full area.

Any water accumulating at this level is then channeled to the drainage system by gravity, depending on the slope.

1. The passive capillary surface drainage TROBA-PLUS 8G serves as the substrate for TROBA-STELZ-DR on a sloped (≥1.5%), weight-bearing waterproofing surface.
2. Place TROBA-STELZ-DR at the joint intersections of the paver elements and fill them with tile adhesive. The adhesive should slightly protrude over the edge of TROBA-STELZ-DR to ensure that paver elements can be tapped into the tile adhesive at the correct height. As an alternative, TROBA-STELZ-DR can also be used as a removable installation formwork for the tile adhesive.
3. Several units of TROBA-STELZ-DR can be stacked for height adjustment in case of uneven substrates.

Schlüter-TROBA-STELZ-DR is made of non-rotting polyethylene. The plastic rings have a diameter of 23 cm and a height of 2 mm.

Material properties and areas of application

Schlüter-TROBA-STELZ-DR is designed to create tile adhesive support rings for the installation of paver elements on terraces and balconies over the drainage mat TROBA-PLUS 8G.

The material is non-rotting, physiologically harmless and compatible with bitumen.
