Rigdgidrain Advanced drainage system

The Ridgidrain ADS system is the complete technical and commercial answer to all non pressure, surface and sub-surface water drainage applications. To date Ridgidrain pipes have been installed on thousands of civil engineering projects including highways, railways, airports, industrial infrastructure, environmental and leisure projects as a direct alternative to concrete and clayware pipes.

The Ridgidrain system also includes 750, 900 and 1050mm diameters. these diameters are unique to Polypipe Civils. Available in 3m lengths with intergral sockets and 6 metre lengths using double couplers. 750 & 900mm are fully certified by the British Board of Agrement as a sealed systems. This range compliments the
Ridgidrain system.

Ridgidrain ADS is supported by a large range of fittings and bespoke fabrications can be manufactured to customer specifications.

Ridgigully features

Unique, patented screw thread corrugations offer:

  • Lightness and superior strength
  • Effective jeying into the concrete surround
  • Nested gullies lock together for easy handling, transportation and safer storage on site


A high quality, light, easy to handle and install alternative to heavy concrete and clay gullies. Ridgigully is manufactured in durable HDPE in 3 sizes.

Ridgigully is suitable for both trapped and untrapped systems with 160mm spigot outlet as standard, which is easily adapted to Ridgidrain, Polysewer and other pipe systems.

A range of accessories is available, including gully risers that key into the gully and eliminate the need for brickwork to finished level.

Ideal for flexible gully connections, 150mm single wall corrugated Ridgiflex has the same external profile as a Polypipe Ridgidrain.

Available in 25m coils, it is fully compatible with standard Ridgidrain fittings.

Fin and Narrow Filter Drains

Manufactured to meet the reuirements of the Highways Agency, Type 6 Fin Drain and Type 8 Narrow Filter are BBA certified for surface and sub-surface water drainage applications.

Following the outstanding track record of conventional Ridgidrain pipe and fittings, we have made a substantial capital investment in a state of the art fabrications facility. Fabrications are manufactured in sizes up metres in diameter and include:

  • Catchpits
  • Manholes
  • Soakaways
  • Pump, sampling and inspection chambers
  • Ducting drawpits

and more...

Fabrications can be made to precise customer specifications with standard products also available for road and rail applications.

Manholes, Catchpits, Valve Chambers, Pump Chambers, Sampling Chambers and Soakway

Ridgidrain catchpits are supplied with inlets and outlets fabricated to customer specification. One piece units can be supplied complete with step irons to BS1247 and can be benched with concrete in the traditional way. Catchpits and manholes can be supplied with intergral base of plain ended.

A range of catchpits are manufactured for railway track and highway filter drainage. 



  • Excellent impact and abrasion resistance properties
  • Use of high performance, virgin polymers for the pipe innerwall
  • Versatility and adaptability
  • Single piece or segmented constructions available
  • Fully compatible with Ridgidrain ADS systems

Flexicon Couplings

Available as straight connections or adaptors for a wide range of pipe materials and sizes.

Robust EDPM flexible rubber couplings manufactured from EPDM to BSEN681-1, ideal for jointing pipes for sewerage, drainage and other low pressure applications.

A full range of adaptors is available for sealed connections to other systems.
