uPVC Underground Drainage Pipes & Fittings

Engineered for long-term reliability in municipal and residential infrastructure, these uPVC underground drainage pipes are manufactured to the strict BS EN 1401 standard. Designed specifically for non-pressure applications, they provide a seamless, corrosion-resistant solution for transporting wastewater, sewage, and stormwater below ground level.

The system offers flexibility in installation methods to suit various site conditions. For smaller diameters up to 315mm, the pipes utilize rigid cemented sockets that create a permanent, watertight seal. For larger diameters or areas prone to ground movement, expansion joints with TPV (Thermoplastic Vulcanizate) rings allow for controlled thermal expansion and minor soil shifts without compromising the integrity of the line.

• Standard Compliance: Fully compliant with BS EN 1401 for non-pressure underground drainage.
• Material: High-quality uPVC resistant to chemical attack, corrosion, and UV degradation.
• Connection Options: Rigid cemented sockets (max 315mm) or flexible TPV ring expansion joints.
• Hydraulic Efficiency: Smooth internal surface minimizes friction loss and prevents sediment buildup.
• Lightweight: Easy to handle and install, reducing labor costs compared to concrete alternatives.
