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. The 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.
Reliable dewatering for driveable surfaces
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 fibreglass-modified, high-strength, waterproof concrete made by Richard Brink. It has wall and floor thicknesses of 20mm. The chosen concrete matrix guarantees wear resistance to chemical influences while the leak-proof surface structure enables rain water to run straight off. The moulded frame is available either in stainless steel or hot-dip galvanised steel.
Meeting demands with different dimensions
Fortis is produced in a standard length of 1,000mm. 500mm-long channels can be supplied as accessory parts. The overall widths of the channels amount to 155mm (DN 100) and 206mm (DN 150). Three different heights are also available: 150, 175 and 200mm.
Installation in next to no time
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. Crossbars in the channel can be used as handles. When installed, the channels have to remain 2 to 3mm under the road surface. Cassette-shaped cut-out sections on the outer sides make sure that the concrete base can form a firm connection with the channel. 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.
Creating visual accents with gratings
Together with premium designer gratings from the company Richard Brink, the Fortis channel presents a cost-effective alternative to stainless steel channels. The covers create visual accents in outside areas. Different models made from stainless steel or hot-dip galvanised steel are available. Just like the channels, heavy-duty longitudinal bar gratings and mesh gratings withstand the impact of traffic. The crossbars in the channel allow the gratings to be used with concealed locks. The Fortis channel can also be fitted with heavy-duty slotted channel tops. Made of 1.5mm stainless steel or hot-dip galvanised steel, they are suitable for load class C 250. Tops made of 3mm-thick material comply with load class D 400.
