Fibertex distributes Dura-Line’s sub-soil drainage pipe and associated accessories used in conjunction with Fibertex geotextiles and composite drainage systems

Fibertex – which celebrates 50 years of business this year – is a supplier locally of Dura-Line’s cable conduit, sub-soil drainage pipe and associated accessories.

“Dura-Line components, which meet stringent quality specifications, are used in conjunction with Fibertex geotextiles and composite drainage systems in various industries, including civil engineering, construction and agriculture,” explains Gerard Dirks, technical manager, Fibertex SA. “Included in the Dura-Line range are Drainex-slotted and Kabelflex-solid bore drainage pipes, Wastex-drilled drainage pipes and Stakbox modular manhole/access boxes.

“Drainex pipes are manufactured from high density polyethylene (HDPE) which is a chemically resistant polymer, with resistance to acids or alkali attack. These durable drainage pipes also offer high impact resistance and are UV stabilised, ensuring extended service life in arduous environments.

“These drainage pipes are bedded and side filled with filter material and properly compacted surrounding soil, to form a complete pipe-soil system. This robust structure can withstand loads in excess of 150 kN/m from soil pressure and other superimposed loads.”

Drainex, Kabelflex and Wastex pipes have a double wall sandwich construction, with a corrugated external wall and a smooth inner wall, with a low coefficient of friction. This design combines high ring stiffness (>450kPa), with excellent flow characteristics, allowing for the optimum utilisation of pipe diameter. Drainage perforations in Drainex pipes are created in the valley of the corrugations to protect the pipe from blockage from drainage aggregate.

These pipes are available in diameters of 75 mm, 110 mm and 160 mm, in coils and in 6 m lengths. Push fit couplings and profiled sealing rings ensure reliable joining and watertight sealing of the pipe fittings.

 Kabelflex pipes can also be used as cable conduits, which are used for protecting underground buried electrical and telecommunications cables. These pipes are manufactured from HDPE for high impact strength. The double wall corrugated construction provides high ring stiffness and a smooth bore ensures easy draw-in of cables. This cable conduit is available in diameters of DN 50, 75, 100 and 160 mm and in 6 m lengths, as well as 25 m and 50 m coils. Simple push fit couplings are supplied with or without a rubber sealing ring.

 Wastex HDPE drainage pipe, developed for use in the collection of leachate in solid waste landfill or containment sites, is perforated with 15 mm diameter holes to prevent organic blocking or clocking.

Wastex pipe, with high impact strength, has a double wall corrugated construction to provide high ring stiffness and a smooth bore ensures high flow rates and velocities. This pipe has a yellow line which marks the apex of pipe to ensure correct orientation of the flow channel. Push fit couplings, with or without rubber sealing rings enhance performance on this drainage pipe.

Stakbox polyethylene modular cable access chambers, which are stackable to create required depths, are easy to install. These robust cable access boxes have a lightweight lid and frame which is tiltable to accommodate sloping terrain.

This range, with multiple knock out points to facilitate cable conduit entries, is available in five sizes, between 300 x 300 mm and 600 x 600 mm.

The Fibertex portfolio of subsoil drainage systems also encompasses PVC pipes and fittings, which includes bends, junctions, rodding eyes and end caps.

Fibertex supplies a comprehensive range of geosynthetic products which also includes nonwoven and woven geotextiles, gabions and mattresses, geosynthetic clay liners, composite cuspated drainage and leak detection systems, erosion control blankets and cellular confinement solutions.

The local operation – with a highly skilled team – supports this extensive products range with a technical advisory and back-up facility throughout Africa.
