Polidren is a corrugated, high-density slotted polyethylene pipe supplied in coils.
It is used to collect stormwater from the ground.
It has a crush resistance of over 300 N with an outer diameter deformation of 5% (internal specification extrapolated from IEC EN 61386-24).
The slots are arranged around the entire circumference (360°), every 120° degrees for DN 63 – 110 – 125 – 160 mm diameters and every 60° degrees for DN 90 – 200 mm diameters.
Slot widths are 2 mm to prevent particles from entering the pipe that may lead to blockage, which would thus render drainage ineffective.
