Heavy duty channel drainage explained

Get the 101 on the different types of heavy duty channel drainage.

Choosing the right heavy-duty drainage channel or trench drain for your project is important to ensure adequate drainage and longevity; find out which surface water drainage solution you need.

Types of heavy-duty channel drainage

Aeroplane travelling over channel drainage.

Channel drainage for industrial areas, such as airports, docks, warehouses and railway platforms must have a load class of F900, meaning they are able to withstand weight of up to 90 tonnes. Only the most robust drainage systems are equipped to cope in these situations. Hauraton’s range of heavy-duty channel drains can be used in these installations.

Hauraton heavy-duty channel drainage comes in a range of different styles: FASERFIX KS, FASERFIX SUPER and RECYFIX HICAP. The main difference between these channels is that FASERFIX drainage channels contain angle housings which are cast into concrete, whereas RECYFIX drainage channels are made from 100% recycled polypropylene. All of these heavy-duty drainage channels can withstand weight up to 90 tonnes, but there are key differences between these and where they can be installed.

Hauraton FASERFIX channel drainage

Hauraton FASERFIX channel drainage is a high-performance surface water management solution. Manufactured from polypropylene fibre reinforced concrete, with an extremely stable connection between steel angle housing and concrete channel body. These drainage channels are exceptionally robust and able to withstand the strongest forces. The polypropylene reinforcement added to the concrete in these channels increases the lateral stability, meaning they are better able to withstand the dynamic forces caused by moving vehicles.

Not only are these channels strong and hard-wearing, but the lightweight concrete channel is also easy to manoeuvre and features a boltless quick­-locking SIDE-LOCK system, making these drainage channels easy to install - saving both time and money. The channel adheres well to foundation concrete, and the grating is easy to fit and can be inserted or replaced using a screwdriver.

Additional Features
  • Extra protection against lateral movement
  • Installation without grating possible
  • Fire resistance class A1 (not flammable) according to DIN 4102
  • Different grating styles available
  • High-quality German manufacturing

FASERFIX KS

The FASERFIX KS drainage channel is available for use in a range of different load classes, from A15 to F900. These drains are an affordable solution for use in commercial and public areas, but not for airport runways and taxiways (despite their F900 loading).

With a 20mm x 20mm angle housing and 10 fixing points for gratings per metre (two of which include an optional locking handle), these channels are robust and easy to install.

The FASERFIX F900 heavy-duty option is suitable for use in a range of industrial environments, a list of which can be seen below. Due to the size of the angle housing, these channels are not suitable for use in airport runways and taxiways, and we recommend FASERFIX SUPER or RECYFIX HICAP.

FASERFIX SUPER

FASERFIX SUPER channel drains are suitable for the highest load industries, including airports. The channels are available from D400 to F900 load classes, while the available gratings range from C250 to F900, with only the heavy-duty F900 being suitable for use in airport trafficked areas.

The F900 SUPER channels have thicker walls than FASERFIX KS allowing them to be used in higher load areas. While the KS has 20mm angle housing, this is doubled in the SUPER channels to 40mm x 40mm for greater strength and lateral force resistance. The number of fixing points for inlaid gratings is also higher on these drainage channels, with 16 fixing points, 8 of which featuring optional bolting.

FASERFIX SUPER F900 is versatile enough to use across a broad range of heavy-duty industries, including all those listed for FASERFIX KS. This solution is a more expensive option compared to FASERFIX KS, but is robust enough to be used in higher load areas, such as airfields, airports and military facilities.

Hauraton RECYFIX HICAP channel drainage

RECYFIX HICAP is a high capacity drainage system suitable for the highest load category, offering all the same benefits as FASERFIX SUPER. All Hauraton RECYFIX channels are made from recycled materials and are 100% recyclable, meaning they comply with environmental standards. However, this does not affect the strength of this option; strong grating materials mean RECYFIX HICAP is suitable for use in areas with the highest loads of F900, including airports.

The RECYFIX channel drains are made from high-grade ductile iron, almost unbreakable material that is resistant to fuels, oils, frost, salt and UV rays, as well as being able to withstand temperatures between - 50°C to + 80°C.

These drainage channels are extremely rigid, with torsion-free ribs and throat voids for added structural integrity. The top inlet of RECYFIX HICAP is made of high-quality ductile iron, which has a much higher tensile and compressive strength than resin and concrete channels, improving the resistance to lateral forces.

Not only are these drains strong and sturdy, but they are also easy to handle and install without the need for any lifting equipment. The lightweight PE-PP plastic channels are connected with tongue and groove joints, and the innovative Link&Lock grating connection makes straight channel alignment quick and easy. The channel body can be cut and drilled on site, improving installation speed, and can be configured as ‘constant-depth’ or ‘stepped-fall’ to suit your project.

One key difference between RECYFIX HICAP and FASERFIX KS or SUPER is the capacity of surface water these drainage systems are able to hold. RECYFIX HICAP is designed for draining large areas of surface water, and features drainage and retention in one component.

Additional Features
  • 100% recycled PP composite body (and 100 % recyclable)
  • 0% water absorption
  • Gratings made from spheroidal ductile iron (KTL ‘cathodic dip‘ coated)
  • Smooth inner surface for superior flow characteristics
  • Cables and pipes can be laid through throat voids between funnels

Airport channel drainage solutions

The requirements for channel drainage at airports is extremely high. The weight of the aircraft applies massive dynamic forces to the ground, and combined with the large area necessary to clear of surface water and risk of extreme weather and fuel spillages, means only the most robust drainage systems are equipped to cope in the challenging environment of an airport.

An airport has airside and landside zones, both of which must be clear of surface water at all times. It is, however, especially important that sufficient drainage is used on the airside tarmac, taxiways, and take-off and landing runways.

Both Hauraton FASERFIX SUPER F900 and RECYFIX HICAP F900 are suitable for use in airports and airfields. When choosing which channel to use for your project, one of the biggest differences between these is the ecological impact of the drainage system. While FASERFIX SUPER F900 is made from concrete, RECYFIX HICAP F900 is made from recycled PP plastic. This is especially important, as airport planning and operations are subject to stringent environmental requirements, making RECYFIX especially well suited.
