NZ Case Study: 135m DN300 ASOE Liner Installed in Napier OPS Group (Offshore Plumbing) has successfully installed 135m of ASOE W Series DN300 FFRP close-fit liner on Thompson Road, Napier.

The pipe was assessed as Grade 4 'Poor' (WSP 2019) with corrosion pits to 9.7mm and prior split failure. The challenge: a live pressure main on a residential hillside with shallow cover. ASOE's trenchless solution delivered a full structural renewal without open-cut excavation.
