INSTALLATION GUIDE

INSTALLATION DESIGN- H 2 0 LINEAR DRAINAGE

F900kN INSTALLATIONS For F900kN installations, the trench for the system to be installed in should be 200mm wider than the chosen channel and 150mm deeper. For larger sizes such as 450 and 600mm, a reinforcement mesh may be required to achieve the desired loading. Please refer to the installation drawings provided or the reinforcement detail for larger channels.

D400kN INSTALLATIONS When installed in asphalt or paving, a maximum loading of D400kN can be achieved with the H 2 0 Linear Drainage system. Reinforcement is required for only the largest channel sizes to meet this loading factor. In asphalt, concrete is required up to the ductile iron top and a wearing course is used to finished surface level. For paving installations the first row alongside the channel should be permanently affixed.

GENERAL PRINCIPLES

Expansion joints should be installed parallel to the H 2 0 Linear Drainage channels along the trench edge to allow for surface expansion and contraction when the system is installed in concrete. Crack inducers should also be used perpendicular to the channels at least every 2m.

When using asphalt or block paving expansion joints and crack inducers are not required.

H 2 0 LINEAR DRAINAGE

GENERAL NOTES The first concrete pour should affix the stabilisers attached to the H 2 0 Linear Drainage channels to the base of the trench, stopping at the base of the channel itself. The minimum concrete grade should be 32/40. The contractor is responsible at all times for ensuring adequate temporary works are provided as well as the structural integrity of the system. As site conditions may vary, the concrete surround, surface finish and reinforcement profile is ultimately the responsibility of the project engineer. Load classes are in accordance with BS EN1433.
