EnviroCulvert Pipes are made of 100% recycled High Density Polyethylene (HDPE) and are designed specifically for medium duty applications in the farming sector.

They have been designed to be strong, but also flexible as opposed to traditional culvert pipes. They have the ability to bend slightly to ease installation, yet not be too brittle or fracture. Standard lengths are 6m.

Full selections of fittings are available for all culvert sizes.
Typically we stock joiners, Y’s, T’s, 45° and 90° Bends.
Special bespoke fittings can also be made to order.

Proudly made in New Zealand by RD Manufacturing
