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



  1. The formwork rings Schlüter®-TROBA-STELZ-DR are installed on top of the passive capillary drainage mat Schlüter®-TROBA-PLUS 8G, which is loosely laid over sloped ( =1.5%), weight-bearing waterproofing membrane.
  2. The Schlüter®-TROBA-STELZ-DR formwork rings are installed at the intersection points of the pavers and filled with thinbed mortar. The mortar should be filled slightly over the edge of Schlüter®-TROBA-STELZ-DR to allow for proper height adjustment of the pavers. As an alternative, Schlüter®-TROBA-STELZ-DR may also be used as a marking template for the thin-bed mortar and reused in other projects.
  3. In case of height discrepancies, several Schlüter®-TROBA-STELZ-DR formwork rings may be stacked on top of one another for levelling.
