HDPE Draincoil Class 400 100mm slotted unsocked drainage pipe is used for longer subsoil drainage runs, retaining wall drainage, landscape drainage and groundwater collection. It is supplied as a 100 metre coil without filter sock.
This 100mm draincoil is manufactured from HDPE and made to AS 2439.1, with SN8 / Class 400 stiffness. The slotted pipe allows water to enter from the surrounding drainage trench, while the unsocked format allows the installer to select suitable aggregate, geotextile or filter material for the site conditions. Confirm trench length, outlet point, aggregate and filter requirements before ordering.
