Installation Instructions for Drainage Channels

Laying Direction

The laying direction of the channel is always opposite to the direction of flow and starts at the ground pipe joint. If elements are laid in two directions it is necessary to join two counterfacing elements. To avoid a gap remove the profile rebate with an angle grinder or use end pieces. When laying, it must generally be ensured that the individual channel elements are installed vertically and are not pushed together!

Basic Principles When Laying Drainage Channels

  • The type of drainage channel to be laid depends on the installation location, corresponding traffic loads, and the planned top course. Installation locations are organized in classes A 15 to F 900 by EN 1433. From class C 250 onwards all gratings must be anchored to ensure traffic safety. The foundation of the drainage channel must be suitable to bear the traffic load.
  • Horizontal loads arising from traffic or thermal behavior of the surface layer must be transferred by means of sufficiently dimensioned concrete encasement of the channel sections and by expansion joints running longitudinally to the channel, especially in the case of adjoining concrete surfaces. The laying direction of the channel is always opposite to the direction of flow and starts at the ground pipe joint.
  • Subsequent surfaces must be executed to be approx. 3 to 5 mm higher than the top edge of the grating or edge protection taking setting and compression into account. Undermining and washing out of decking and channels must be prevented by suitable measures.
  • Where extreme horizontal forces are expected at right angles to the channel, e.g. on railway crossings, ramps or highways, the drainage channels should be secured laterally with reinforced decking concrete.

Load Classes to EN 1433

Class A 15

walkways, cycling paths, green areas

Class B 125

pedestrian zones, car parking spaces

Class C 250

kerb areas, emergency lanes, car parking spaces

Class D 400

road surfaces, pedestrian streets

Class E 600

industry, military, high wheel loads

Class F 900

airport surfaces, docks, very high wheel loads

Concrete Encasement to EN 1433

Type I

A drainage channel type I does not require a concrete encasement for bearing the loads. Foundations are only required to discharge the exerted vertical and horizontal forces.

Type M

A drainage channel type M requires a foundation and encasement of concrete that can discharge occurring vertical and horizontal loads into the foundation after installation.

The paving must be installed in such a way that dynamic shear forces do not affect the channel sides. This is achieved by a non-positive bond between the paving.
