Management at ROHR were involved with the development of this product in its infancy. The product was born through the Brisbane City Coucil’s NUSEWERS scheme.
Under the scheme, a fully welded solution was needed to help prevent tree root intrusion and also sockets becoming disconnected in drainage systems due to soil movement.
The product is essentially a grey striped black pipe with a light colour internal lining to allow camera inspection.
Innovations in die head technology have allowed these to be internally coextruded from 110mm up to 800mm.
