HDPE Line
HDPE lining offers the sewer structure several additional advantages that are not always appreciated. Its surface is smoother than concrete, and thus a pipe with a smaller internal diameter can be used. Alternatively, the same diameter can be used at a flatter gradient. The long-term pullout strength of the lining anchors is able to cope with a ground water pressure in excess of 10m. If necessary the HDPE lining can be welded together at the joints by applying a bead of HDPE to make the lining continuous and create a water- and gas-tight joint. The abrasion resistance of the HDPE is actually greater than that of concrete.
Concrete pipe with a cast in HDPE lining has all the advantages of a strong rigid pipe that keeps its shape as well as those of a plastic pipe that is inert to acid attack. It is the best pipe for large diameter gravity pipelines in almost any condition.

Jacking Pipes
The benefits of pipe jacking are well established. By choosing pipe jacking over open-cut construction, owners can have a precisely installed pipeline with less disruption to the public – and at a competitive price, with less noise and lower emissions.
