Twinwall carrier drainage pipe is made from HDPE plastic and manufactured by a twin extrusion process whereby two layers are simultaneously extruded one inside the other and heat welded together in one continuous step.
The solid outer wall is corrugated, providing brilliant structural strength and reduces the possibility of on-site damage. The inner wall has a smooth seamless finish to assist hydraulic flow and the design also prevents silt accumulation.
This plastic pipe is used for highway filter and carrier drains, rail track drainage, golf course land drainage, catch pits and land reclamation projects.
Diameters available: 100mm to 3000mm.
