Drenopal is a slotted pipe used for ground stormwater collection, capturing leachate or dispersing stormwater into the ground.
It is manufactured in three different stiffness classes (SN 4, SN 8 and SN 16 kN/m2) from a bar of Ecopal pipe, a corrugated pipe made of high-density polyethylene or high elastic modulus polypropylene.
The Drenopal slotted pipe features a surface corrugated on the outside and smooth on the inside: the slots make it possible to collect groundwater and to channel it to a final destination. When there are drainage trenches, the pipe can be used to collect and disperse the stormwater into the ground.
The pipe is slotted as required, using a special tool, at 220° (channel slotting) or 360° (full circumferential slotting). Slot widths and lengths vary depending on the diameter and type of slot. Other types of slotting can be evaluated according to customer requirements.
