GRAF Draining tunnel

Infiltration systems rainwater and treated sewage

It is used during the infiltration of water into the ground. Tunnel absorbs water, and then successively infiltration it in the ground. The device can be sited for pedestrian and car traffic. When using drainage tunnels, it must be remembered that it can only be used in permeable and poorly permeable soils where the groundwater level is sufficiently low. The tunnels can be connected to each other by lengths or bottoms which increases the retention capacity. The drainage lines should be terminated with closing plates. We also offer another drainage tunnel - the BECKER 320L drainage tunnel.
