Solid Twinwall Drainage Pipes
Drainage Sales 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.
The pipe itself has ribs in the outerwall for added strength and a smooth internal bore to ensure a free flow.
Because of its excellent abilities to withstand compression and hence being crushed by heavy weights and forces, Twin Wall drainage is most commonly found carrying surface water beneath paths, carriageways, ditch drains, culverts, roads and railways.
Culverts, which is the name given for any type of structure that allows water to flow under an obstruction, often make use of the extraordinary properties of twin wall as they are usually embedded quite deep in the ground and surrounded by soil.
Our Twinwall systems are also available in a perforated pipe for use in land drainage. Joiners, bends and ring seals are available to complete the range.
