Twinwall Pipes & Fittings - Surface Water Drainage

Twinwall Drainage Pipe & Fittings

Twinwall pipes are used in surface water drainage systems to drain excess water in a range of applications such as agricultural, highways, railways and airports. These pipes can also be used to drain excess surface or stormwater in domestic settings such as garden drainage.

Manufactured from HDPE, these weatherproof, lightweight and strong pipes feature a smooth internal surface for an increased flow rate, while the outer surface has a ribbed structure for a high compressive strength.

Twinwall pipes are available as unperforated (solid or carrier drain) and perforated (filter drain) high-quality JFC twinwall from JDP is stocked in-depth in a range of sizes, from 110mm to 600mm.
