Since it was established in 2010, Edge Underground has been at the forefront of the Australian microtunnelling industry, pushing its boundaries, improving equipment and finding ways to complete some of the most challenging projects that no one else will take on.

Edge Underground was founded by Managing Director, Stuart Harrision, a well-known figure in the Australian and international microtunnelling industry as a trenchless expert, pioneer of innovation and the inventor of the AXIS laser guided boring system.

Iplex’s Restrain a win for Townsville Sewer Upgrade (Trenchless Australasia)

Iplex’s innovative product Restrain has contributed to the success of the Townsville Wulguru Gravity Sewer Upgrade. Trenchless Australasia – 26 September 2022

Restrain is a PVC-U pipe designed for both new sewer networks and for replacing existing underground gravity sewer infrastructure. The pipe sections have a threaded socket and spigot joint. The rubber ring seal for the joins is nested in a groove behind the spigot thread, which ensures that it is not dislodged during installation.

Restrain Sewer Pipe’s compatibility with trenchless technologies means that it was the perfect choice for use on the Wulguru Gravity Sewer Upgrade. Managing Director of Edge Underground, Stuart Harrison, was the installing contractor on the project. Harrison says that the biggest thing saved by using Restrain was time.
