225mm Unperforated CorriPipe

Our 225mm 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.
