For heavy loads, Richard Brink has developed the Fortis dewatering channel made from concrete, which complements the company’s selection of metal linear drainage elements. This new product is characterised by its low weight: the concrete channel has a nominal width of DN 100mm, height of 150mm and weighs just 20kg. Transportation, installation and storage is therefore much easier compared with heavier concrete channels. Despite its light weight, the channel can withstand a weight load class of up to D 400. This means it can be used for dewatering in a number of settings, such as private courtyards, parking areas, road construction, underground engineering and even industrial areas.
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 D 400 and can therefore be relied upon to withstand loads of up to 40 tons.
Reliably dewatering driving 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 sufficiently 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 with regard to chemical influences. 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.
