The CorriPipe is a twin-wall pipe made of a blend of extruded recycled and primary HDPE (high density polyethylene) raw material, with minor amounts of masterbatch. The outer wall of the CorriPipe? is corrugated providing excellent structural strength which reduces the possibility of onsite damage. The inner wall has a smooth seamless finish to assist hydraulic flow.

The primary function of the CorriPipe is to serve as a twin-wall polyethylene drainage pipe designed for surface and stormwater drainage. It is used in various applications, including civil engineering, construction, sports amenities, agriculture, and other sub-soil drainage systems. Its corrugated outer profile provides excellent structural strength, while the smooth inner wall ensures increased flow capacity.
