Our Twinwall pipe is made from HDPE (high density polyethylene), a plastic material that is lighter than the traditional concrete alternatives yet is much stronger than PVC. The pipe has ribs in the outer wall for added strength and a smooth internal bore to ensure a high flow rate.
Our Twinwall drainage pipe is BBA Approved. It is also certified for use by the Highway Authorities Product Approval Scheme (HAPAS) the national Roads and Bridges Authority.
Twinwall pipes can be cut along any of the external ribs using a standard handsaw. Joints, bends and junctions are available; remember to add two ring seals for each fitting when using twin wall for stormwater (not required when using perforated pipe for land drainage).
Plain pipes are used for the carrying of surface and stormwater. Perforated pipe systems are used as an alternative to land drain to collect excess rainwater from the ground. It is often used in ditch drains and culverts, or in leisure and sporting facilities such as sports pitches and particularly golf courses.
An element of the HDPE material is recycled. This means that contractors working to achieve recycled content targets set by local authority planning departments can include our twinwall pipes in their calculations.
