About the product
Our Geopipes are slotted and extruded from HDPE, with an innovative double wall. The external wall is corrugated while the internal wall is smooth with a very low coefficient of friction, combining high ring-stiffness (which resists damage due to installation and overburden) with excellent flow rates. The drainage perforations are created in the valley of the corrugations which protect the pipe from blockage from drainage aggregate and make it ideal for use with composite drainage systems and geotextiles. Our HDPE geopipes are extremely resistant to both acid and alkali attack.
