Installation Guidelines BG-SI safety channels

General Guidelines:

1. The load class (according to EN 1433) in the various local laying situations must be taken into consideration.
   
   
2. The installation can only take place on a base course that has been mechanically compressed, or reinforced concrete slabs, according to the instructions of the person in charge of the project. The BG-SI safety channels have to be laid on interval blocks and moulded with very firm mortar, respectively on a damp foundation. It is essential, that the proper tools be used when laying the drain elements (e.g. BG installation tools)
   
   
3. A supporting wedge at the side is necessary, according to statically requirements.
   
   

4. Start the laying of the safety channel at the junction to the outlet.
   
   

5. The butt joints (width of joint at least 10mm) between each individual drain component can be sealed with the most suitable insulation (see BG-Insulation Systems processing guidelines)
   
   
6. In the case of insulation of bordering areas, great care must be taken to ensure that mechanical damage to the drain elements is out of the question.
   
   
7. Necessary spacers (as compensation for any horizontal force occurrences), between the BG-SI safety channels and the connection to the roadway, can be fixed directly onto the drain element. In the case of the spacer crossing the drain, it must be fixed so that the spacer arrives at the exact place where the drain terminates.
   
   

8. All bordering concrete areas should have a steady height of approx. 3-5 mm higher than the surface of the drain.
   
   

9. The same installation guidelines also apply to gullies.
