The 375mm solid twinwall pipe is ideal for gravity surface water and stormwater drainage applications. This pipe is used for highway filter and carrier drains, rail track drainage, golf course land drainage, catchpits and land reclamation projects. An external corrugated wall is fused with an inner smooth wall to ensure strength and rigidity on the outside and efficient flow on the inside. The design, unlike traditional single-wall pipes prevents silt accumulation.

• Smooth internal wall prevents silt accumulation
• Provides increased flow rates
• Fully Leak tested to HAPAS requirements when used with rubber seals
• SN6 strength
• Easy to cut on site - reducing plant and labour costs
