Installation Guidelines BGF-Z shallow channels

General Guidelines

1. The load class (according to EN 143) in the various local laying situations must be taken into consideration.
   
   
2. BG concrete drains have to be laid on in an earth-moist foundation. (See the table for measurements). Flat drains / Low profile drains being laid in the area of steel concrete flag stones, respectively existing concrete foundations; have to be laid in a 1-2 cm deep bed of wet mortar. On all accounts, the foundation must be capable of withstanding heavy loads.
   
   
3. A supporting wedge at the side is necessary, according to statically requirements (See table below).
   
   
4. When laying the drains, it is important to start with the drain run-off. Each drain is marked with an arrow showing the direction of flow.
   
   
5. The integrated safety notch between each channel can be sealed with the appropriate sealing compound, according to the area of use. (See the processing guide lines of the BG - Sealing System)
   
   
6. Pay attention to the fact, that the grates must be inserted prior to the construction of the adjoining floor surface. (For Example during the usage of a pile-driver) and to rule out any mechanical damage, make sure that they do not come into contact with the channels.
   
   
7. By use in areas subjected to heavy traffic, we advise that the covers employed are screwed on according to the place of operation, frequency and speed of vehicles driving over the surface (screwable up to 8 times). It is important to make sure that the screw connections represent a powerful and durable link.
   
   
8. Between the BG channel and the connection to the roadway, it may be necessary (e.g. owing to horizontal forces in the vicinity of concrete areas) to insert a spacer with a maximum interval of 0,5 m. 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 stops.
   
   
9. The entire length of all adjacent concrete surfaces should be approximately 3-5 mm higher than the surface of the grates.

In areas where the presence of strong chemical products can be expected, (such as substances to induce thawing, acids or caustic solutions etc) we strongly advise the installation of drains with stainless steel edges
