Linear channel drainage systems to collect water from roads, pavements and driveways.

Channel drainage systems with removable gratings or continuous slots provide an efficient means of removing surface water, without the gullies or buried pipes needed by point drainage systems.

Linear drainage systems are relatively quick, easy and economical to install and maintain. They typically only require shallow construction and minimal excavation.

Channels incorporate an internal or external fall or slope, or have a constant depth.

Manufacturers champion different shapes and designs as being optimised for the rate flow of water, which not only helps in dispersing rainwater, but also prevent silt settling and causes self-cleansing movement.

Drainage channels with removable gratings

Removable grating channels have functional galvanised steel grids or solid covers, ornate cast iron gratings, or high-specification resin polymer or stainless steel fittings. In many cases, the grating itself is a design feature, which will integrate well with paved surfaces in public spaces or commercial developments, and complement other building products and architectural elements. Channels with fixed, integral gratings, which provide a high level of vandal-resistance, are also available.

Slotted linear drains

Slotted linear drains integrate especially well with natural stone or concrete block paving schemes, and, in some cases, can be fitted right alongside building facades. The single continuous slot is unobtrusive yet effective in removing surface water quickly without ponding.

Applications

Civic / industrial applications

Channels for civic and industrial surface water drainage infrastructure include products for roads, pavements, car parks and transport terminals through to stockyards, airports and military sites.

Residential applications

Channels for residential applications include pathway, patio, driveway and threshold drains.

Other applications

Distinct products are also available for combined drainage kerbs and sports channel drains. Special designs that integrate lighting fixtures are also available for low level lighting of paved areas.

Composition and manufacture

While gratings or slot finishes are made from galvanised steel, stainless steel or ductile iron to provide the best appearance for a project and to handle the necessary direct traffic loadings, the construction of the main body of the subsurface channel is also critical to its fitness for purpose.

Plastics

GRP (glass reinforced plastic), polyethylene, polypropylene channels are especially lightweight, easy to transport, and quick to install. They are resistant to abrasion, frost, rust, hot asphalt and chemicals, and strong enough to prevent damage during site handling. They tend to be suitable for light-duty applications.

Polymer concrete

Proprietary polymer concrete channels can be 75% lighter than traditional concrete channels. Again, they are resistant to frost, chemicals and road salt. Steel edge supports can reinforce the strength of the channel.

GRC

GRC (glass reinforced concrete) channels have a high strength-to-weight ratio and are resistant to damage, whether from frost, chemicals, road salt or during handling.

Technical data

Dimensions

Channel drainage elements usually come in standard lengths of 500mm or 1000mm.

Some product ranges include elements as long as 1500mm or 2000mm, which can help with the quick installation of longer runs of drainage.

Nominal internal widths tend to range from 100mm up to 900mm for very high capacity channels.

Specially designed shallow channels can be specified for sites where excavation is restricted.

Performance / load classes

External channel drainage is specified for areas subject to pedestrian or vehicular traffic, and is rated according to the load classes set out in BS EN 1433:2002 for drainage channels set in trafficked surfaces.

 Class  Load  Applications
 A15  15kN  Residential and light pedestrian and cycle traffic
 B125  125kN  Footpaths, pavements and small private car parks
 C250  250kN  Kerbsides, car parks, hard shoulders and general commercial areas
 D400  400kN  Carriageways, trafficked sections of roads and highways
 E600  600kN  Industrial areas, petrol stations and light commercial forklifts
 F900  900kN  Aircraft pavements, docks, heavy forklift trucks and abnormally heavy wheel loads
