We have further expanded our range of CorriPipe™ products with the introduction of 750mm, 900mm and 1050mm sizes. Our 900mm fully perforated twinwall drainage pipe is ideal for land drainage and flood risk management projects. The perforations in the pipe enable water to be collected and carried away to a soakaway, water course or surface/rainwater drainage system. 

Our large diameter CorriPipe™ is manufactured from recycled HDPE utilising a twin extrusion process. The inner and outer layers are simultaneously extruded, one inside the other and heat welded together in one continuous process. The outer solid wall is corrugated providing excellent structural strength, reducing the possibility of on-site damage. The inner wall has a smooth seamless finish to optimise hydraulic flow. CorriPipe™ XL comes in 6m lengths including integrated coupler. 

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

•  Superior structural strength with SN2, SN4 and SN6 options available. 
•  Unique Integrated socketing system (traditional independent sockets also available). 
• Smooth internal plastic bore with reduced hydraulic resistance. Manning’s coefficient of 0.012 allows for greater flow capacity and also a greater factor of safety. This also reduces sediment or debris build-up when compared to concrete or steel. 
• Lightweight when compared to traditional materials such as concrete or steel. E.g. (Up to 90% lighter than concrete) 
• Fully leak tested to HAPAS requirements when used with rubber gaskets. 
• Standard 6m lengths make it quick and easy to install, eliminating wastage and reduces labour and plant costs. E.g.  (Up to 6 times faster installation compared to concrete). 
  
• Parallel corrugations allow pipe to be easily cut square on site if required. (Spiral wound pipe makes it difficult to create a square cut on site if required) 
• JFC CorriPipe™ XL is available unperforated, fully perforated or half perforated. 
• Manufactured from exceptionally durable HDPE material with excellent corrosion resistance and long term performance. 
• Resistant to most naturally occurring chemicals and is therefore suitable for use on the majority of soil conditions. 
• Full range of fittings and accessories available. 
• Can typically be installed with cover depths from 0.6 to 10m*
