Drenopal

Corrugated pipes "Drenopal"

The constant search for innovative solutions resulted in the production of Drenopal, a pipe specially designed for meteoric water drainage and percolate collection.

Drenopal is produced from a slotted Ecopal pipe. A special equipment guarantees a large range of slots.

Drenopal is available in many different diameters, 160 to 1200 mm, in 6 m pipes and according to the stiffness classes SN 4 kN/m² and SN 8 kN/m² and SN 16 kN/m2 and with 220° or 360°slots.
