Application and Function

Waterproofing assemblies on balconies and terraces frequently lack sufficient height to connect smoothly to fixed building parts, door elements or walls.

According to DIN 18 195, Part 5, 7.1.6, waterproofing layers must overlap the upper edge of the covering by 15 cm. The same DIN standard requires door connections to have thresholds with a height of 15 cm. However, this requirement may be waived in accordance with building directives for flat roofs if suitable measures are in place to ensure drainage. The installation of Schlüter®-TROBA-LINE guarantees drainage even with low connection heights. The system also allows for special constructions with stepless transitions.

Schlüter®-TROBA-LINE-TL consists of a perforated, U-shaped lower section and a perforated, U-shaped upper section. It is installed over the area drainage systems Schlüter®-TROBA or Schlüter®-TROBA-PLUS.

Schlüter®-TROBA-LINE-TLR is a variation with an upper drainage screen of galvanized steel, which is inserted into the U-shaped lower section of stainless steel. The water drains through the openings of the channel to the waterproofing layer, where it runs off in the area drainage between the waterproofing layer and the surface covering toward the drainage exit. This prevents the accumulation of water in the door area or in all places with low connecting heights.

Schlüter®-TROBA-LINE-TLG is a variation with a closed lower section, which is used to drain water to a lateral exit point.

Installation

1. The balcony or terrace area must feature a functional and sloped waterproofing assembly.
2. Set Schlüter®-TROBA-LINE onto mortar points or install Schlüter®-TROBA-LINE-TL/H in the area of door elements or wall connections with the use of the height adjustment feature to stop water from accumulating. When installing Schlüter®-TROBA-LINE, it must be ensured that the number of mortar points or height adjustments, on which Schlüter®-TROBA-LINE rests, matches the expected loads. In order to guarantee proper water drainage, a sufficient part of the channel may not have mortar underneath.
3. In typical installations, Schlüter®-TROBA or Schlüter®-TROBA-PLUS should first be laid over the waterproofing layer as an area drainage and protective layer. Regardless of the installation system of the surface covering, a sufficiently large drainage space must be ensured above the waterproofing layer, in which the water draining off through Schlüter®-TROBA-LINE can securely run off to the drainage exit.
4. If several channel elements are to be combined, they can be connected with the U-shaped parts (see Fig. 1). The same U-shaped parts can also serve as end caps (Fig. 2).
5. The screed or other selected covering construction is now installed in such a way that it abuts the properly aligned Schlüter®-TROBA-LINE. Reinforcement: When using the drainage channels Schlüter®-TROBA-LINE-TL and -TLG in the widths 110 mm and 160 mm, it may be necessary to install the reinforcement Schlüter®-TROBA-LINE-TL/V, depending on the load.

Material

Schlüter®-TROBA-LINE-TL consists of stainless steel (material no. 1.4301) and is roll formed from bands of perforated stainless steel.

The upper screen of Schlüter®-TROBA-LINE-TLR, which is inserted into the lower section of stainless steel, is made of galvanized steel.

Material properties and areas of application
The suitability of the various drainage elements and the appropriate width (75 mm, 110 mm, 160 mm) must be clarified for each project in accordance with the anticipated volumes of water as well as mechanical and other stresses.

Maintenance

Schlüter®-TROBA-LINE does not require special maintenance or care. The drainage channel must be kept clean and free of debris that can cause clogging. The upper section can be removed for cleaning out the lower section.

Schlüter®-TROBA-LINE-TL

Schlüter®-TROBA-LINE-TL is a drainage channel of stainless steel, which can be installed in balconies and terraces with a low connecting height to door elements to prevent the accumulation of water. Water runs off below the surface covering in the area drainage system to the drainage exit.
Width: 75 mm / 110 mm / 160 mm
Height: 20 mm / 40 mm
Length: 0.75 m / 1.0 m / 1.5 m / 2.0 m

Schlüter®-TROBA-LINE-TLR

Schlüter®-TROBA-LINE-TLR is a drainage channel with a lower section of stainless steel and an upper drainage screen of galvanized steel, which can be installed in balconies and terraces with a low connecting height to door elements to prevent the accumulation of water. Water runs off below the surface covering in the area drainage system to the drainage exit. The grates are able to support relatively high traffic loads.
Width: 110 mm / 160 mm
Height: 20 mm / 40 mm
Length: 0.75 m / 1.0 m / 1.5 m / 2.0 m

Schlüter®-TROBA-LINE-TL/H is a height adjustment insert that allows for the seamless height adjustment of the drainage channels Schlüter®-TROBA-LINE-TL4 and Schlüter®-TROBA-LINE-TL4R up to approx. 40 mm height.
TL2H
height adjustment from H = 0 - 20 mm
TL4H
height adjustment from H = 20 - 40 mm
Width: 75 mm / 110 mm / 160 mm
Length: 135 mm

Schlüter®-TROBA-LINE-TL/V

In the event of higher traffic loads, e.g. from foot traffic or wheelchairs, it is recommended to use the reinforcement Schlüter®-TROBA-LINE-TL/V along with the widths 110 and 160 mm.
Height: 20 mm / 40 mm
Length: 0.75 m / 1.0 m / 1.5 m / 2.0 m
