WEIDALINE HDPE subsoil drainage pipes, available in single or double-wall, perforated or non-perforated options, effectively remove excess water in architectural, sewage, irrigation, and agricultural applications. These flexible, corrugated pipes enhance ground stability, reduce foundation movement caused by soil moisture fluctuations, increase soil strength, and protect properties from water damage. Typically installed within a geotextile envelope of sand or gravel, the pipes are connected using HDPE couplers and fittings to create efficient subsoil drainage networks for improved water management.

Strong & Tough – The corrugated wall design of WEIDALINE subsoil pipes provides high ring and bending stiffness, delivering exceptional long-term load-bearing performance. These pipes can support vehicle loads and withstand burial depths of up to 20 metres, subject to soil conditions.
Flexible – Capable of bending and adapting to soil movement without risk of fracture.
Corrosion Resistant – HDPE requires no protective coating or painting to prevent rust.
UV Resistant – Contains carbon black additives that protect against UV damage during outdoor exposure.
Lightweight – Easier to transport, handle, and install due to HDPE’s light nature.
Chemical Resistant – HDPE resists a wide range of soil, sewage, and wastewater pH levels without degrading.
Abrasion Resistant – Outperforms concrete and steel by resisting wear and rust, ensuring long-lasting flow efficiency in double-wall pipes.
Fast Installation – Supplied in long lengths with fewer joints, speeding up the installation process.
