How to install this product

  1. Balconies or terraces must feature a functional and sloped waterproofing assembly.
  2. Place TROBA-LINE-TL on spots of mortar or use the height adjustment TROBA-LINE-TL/H in the area of door elements or wall connections to prevent the accumulation of water. When installing TROBA-LINE, make sure that the number of mortar spots or the height adjustments supporting TROBA-LINE are appropriate for the anticipated stresses. To ensure proper water drainage, place mortar only under a part of the channel.
  3. As a general rule, TROBA or TROBA-PLUS should be installed over the waterproofing assembly as a surface drainage and protection mat. Regardless of the covering system, be sure to leave a sufficiently large drainage space above the waterproofing assembly to safely channel the water through TROBA-LINE-TL to the drainage exit.
  4. Multiple channel elements can be connected with the supplied U-shaped brackets. These U-shaped brackets can also serve as end caps.
  5. The screed or other selected covering assembly can now be installed in such a way that it abuts the properly aligned


Depending on the anticipated stresses, it may be necessary to install the reinforcement Schlüter-TROBA-LINE-TL/V for the drainage channels TROBA-LINE-TL and -TLG in the widths 110 mm and 160 mm.
