More Information on Twin Wall Drainage Pipes:
It has a higher strength to weight ratio, plus the flexibility to resist traffic loads with a design life in excess of 60 years. The very first twinwall pipe surface water drainage system in the UK with Highways Authority Product Approval Scheme (HAPAS) standing (up to 600mm), Polypipe Ridgidrain twinwall drainage pipe is used for non-pressurised surface and sub-surface drainage applications.
Twin wall drainage pipes have a friction wall for improved hydraulics and the pipe comes with integral sockets for pipe alignment. Polypipe Ridgidrain twin wall drainage pipe is provided in 6m lengths, reducing the number of risk and joints of leakage.
A Long-term Solution
As a result, specifying Polypipe Ridgidrain twin wall drainage brings reduced weight, strength and sustainability with no compromise on long term effectiveness, to a job.
Made from 100% recycled, higher strength HDPE with a structured wall design, the twin wall drainage pipe is strong yet flexible, with high resistance to the most common chemicals and excellent all-round performance.
