Basetec Services was engaged to supply and install a 2.5mm thick HDPE liner to protect the concrete from Hydrogen Sulphide attack.

The liner was applied throughout the inlet and outlet channels, as well as the bypass channel and grit vortex chambers to both the eastern and western sides of the project. 

The total area of work was approximately 1000m² and consisted of some very tricky and detailed areas. 

Basetec completed all of its own internal spark and pull off tests for the HDPE material in accordance with the manufacturers and project specifications.
