Project Overview
Flume and spillway remediation for Hydro Tasmania, completed within a fixed outage window.
Building on the team and methods used at the Tarraleah Canals and Monpeelyata Flume, two crews worked concurrently inside the flume and on the spillway. Flume joints were removed, cleaned and renewed with Neoferma rubber and Sikaflex sealant, concrete repairs followed the break-out, clean, treat and reinstate method, and new spillway concrete was dowelled into rock. Concrete was line-pumped up and over the flume to keep clear of overhead HV lines, with crane-lifted scissor lift and scaffold access into the flume.
Key figures: Joint renewal, concrete repairs and spillway works in one outage.
