The project involved the installation of a 70 m long section of DN 534 iMPREG GL16 liner, with a wall thickness of 3.8 mm, on a new water main.
The GL16 liner is designed to restore conventional pipes from DN 150 to DN 1600 and features a fibreglass design allowing nuanced gradations of wall thickness to be produced.
The liner is approved by the German Institute for Construction Technology and conforms to ISO 9001 quality standards, as well as ISO 14001 energy management system standards.
Challenges that were overcome during the project included the host pipe for the new main running under a railway line, meaning there was a limited window for installation to be completed.
Furthermore, the liner had to be lowered into a 7 m deep pit, requiring a crane on site for placement.
With careful planning and an expert crew, M. Tucker and Sons was able to smoothly install the liner to the satisfaction of all parties.
