Schlüter®-TROBA-STELZ-DR | Function | Schlüter-Systems


Application and Function

Schlüter®-TROBA-STELZ-DR are plastic formwork rings of non-rotting polyethylene that are used as installation aids for large format pavers on balconies and terraces.

The 2 mm high plastic rings are installed on top of the drainage mat Schlüter®-TROBA-PLUS at the intersection points of the pavers as single-use or reusable formwork rings and are filled with thin-bed mortar.

Following the installation of the thin-bed mortar, the corners of the pavers are aligned over the thin-bed mortar rings and set to the right height.

The joints remain open to ensure that the finished covering drains through the joints between the pavers to the drainage level of the Schlüter®-TROBA-PLUS membrane. The drainage water is routed to the gutters by gravity, depending on the installed slope.
