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 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.
