Installation Guidelines BG safety channels

General guidelines:

The following installation guidelines and examples are designed to use for an accepted standard. The load class and the installation location according to EN 1433 have to be adapted to the location conditions from the planner. Consider the common known technical rules and guidelines which are accepted among experts. In special cases contact the BG - application engineers.


Installation instruction BG-SI

  1. BG concrete drains are set up in a concrete-bedding according to Ö-Norm B4710-1 or in drainage-concrete according to RVS 08.18.01. With hardened concrete foundations you have to set up the channel in a mortar bed of at least 2 cm. Depending on the static demand you will need a supporting wedge or a concrete casing even with steel reinforcement - for details see table and sections.

  2. Start setting at the outlet of the channel line. Each channel is marked with an arrow showing the direction of flow.

  3. The rebated joint between the channels can be sealed and cemented with appropriate sealing compounds – for description of material and quantity calculation see - BG sealing system.

  4. Before assembling the adjacent cover layer make sure that the covers are inserted and the channels are braced adequate against compression. Pay attention not to damage the channels while compacting the superstructure and the pavement (asphalt, pavement, concrete).

  5. If there are occurring horizontally forces (e.g. due to concrete areas, gradients,…) you have to build out an adequate running joint at an interval of 30 – 200 cm from the channel. In a concrete area where there are running joints crossing the channel line they have to be arranged to go through a rebated joint of the line.

  6. All adjacent surfaces should be permanently 3-5mm higher than the surface of the channel/grate to avoid mechanical damage (e.g. snow clearing) and to guarantee the water drainage.

  7. The installation instructions also apply to sump units.
