“Fortis” concrete channel

An enormous amount of force acts on areas exposed to particularly high wheel loads – due to lorry traffic, for example. The installed dewatering systems have to be able to cope with this at all times, which is why DIN 1433 “Drainage channels for vehicular and pedestrian areas” specifies load classes. Our “Fortis” concrete channel is designed for classes A 15 to E 600 and can therefore be relied upon to withstand loads of up to 60 tons. The heavy-duty dewatering channel is used, among other things, in driveways, roads, courtyard surfaces in front of buildings and parking areas, where it ensures reliable linear drainage. Rainfall can flow over concrete inlets that feature run-off pipes. A direct connection to a shaft or existing channel is also feasible.

The channel’s appropriately dimensioned concrete framing comprising base and edge restraints ensures load transfer. The channel body is made of high-strength, waterproof concrete made by Richard Brink. It has wall and floor thicknesses of 20mm. The chosen concrete matrix guarantees wear resistance to various chemical influences while the leak-proof surface structure enables rain water to run straight off. The moulded frame is available either in stainless steel, hot-dip galvanised steel or cast iron.

The low weight of the concrete channel benefits transportation on the one hand and straightforward installation on the other. It can be mounted by one person without the need for extra equipment or lifting tools. When installed, the channels have to remain 2 to 3mm under the road surface. Cassette-shaped cut-out sections on the outer sides prevent the channel from floating up and make sure that the concrete base can form a firm connection with it. A tongue-and-groove system with integrated rubber seals on the ends of the channel does away with the need for complex sealing work along the joints.
