225mm Fully Perforated CorriPipe


Tax included.


Our 225mm fully perforated twinwall drainage pipe is ideal for land drainage and flood risk management projects. The small perforations in the pipe enable water to be collected and carried away to a soakaway, water course or surface/rainwater drainage system. 

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. 

CorriPipe™ packs are colour coded for easy identification of pipe type. Red: Fully Perforated Pipe, Yellow: Half Perforated Pipe and Green: Unperforated Pipe.
