Our Twinwall Drainage is manufactured from HDPE for use in Surface Water and Stormwater applications. We stock a range of sizes from 150mm right up to 600mm. This pipe is very strong and is ideal for use beneath paths, roads, airport and railways. It is also commonly used in the construction of infrastructure for the leisure, agricultural and commercial sectors.
Our unperforated Twinwall drainage pipes come in range of sizes from 150mm to 600mm. The perforated pipes are available from 150mm to 300mm. A range of joiners, 45° and 90° bends and junctions are available to complete the range. Ring seals can be inserted into as required to ensure a completely watertight seal.
Our Twin wall pipes are made from HDPE, a high density 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.
CUTTING AND JOINING
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 OR PERFORATED
Plain pipes are used for the carrying of surface and stormwater. Perforated pipes 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.
