Drainage & Catchpits

Polypipe Civils Twin Wall Pipes

The Ridgidrain Advanced Drainage System is the complete technical and commercial answer to all non-pressure, surface and sub-surface water drainage applications. Ridgidrain pipes have been installed for highway, rail and airport infrastructure projects as a direct alternative to concrete and clayware pipes. The Ridgidrain system was the first drainage product in the market to achieve the new HAPAS specification (Highways Authorities Product Approval Scheme) issued by the BBA.

Pipes and fittings from 100mm up to 600mm diameter are available in unperforated, half perforated and fully perforated 6m lengths.

Pipes and fittings in diameters of 750mm and above are now available as part of the Ridgistorm-XL large diameter range.
