Twinwall Drainage is manufactured from High Density Polyethylene(HDPE) for use in Surface Water and Stormwater applications.
The pipe itself is co-extruded, with ribs in the outer wall for added strength and a smooth internal bore to ensure a free flow. Our Twinwall systems are available either perforated or solid in a wide range of sizes.
All of Our 110mm and 160mm pipes and the majority of our fittings are manufactured from PVC-U. Inspection Chambers, adjustable bends, gully traps and grids are manufactured from polypropylene.
Pipes and fittings are manufactured in Golden Brown. They are designed for use in gravity drainage, sewerage and storm water installations at depths of up to 10 metres. You can learn much more about these products in our Guides & Tips section.
Our land drain is a very efficient, single wall, corrugated and perforated pipe used underground for collecting excess rainwater from boggy areas such as gardens and playing fields. The water filters into the land drain via the perforations and is then run off to a suitable dispersal point such as soakaway, watercourse or a surface water drain. It works very well when used in conjunction with our soakaway system.
For those who wish to collect and re-distribute their rainwater, we sell rainwater harvesting systems designed in accordance with BS8515:2009 to the highest standards.
