Trevallyn Dam was built in 1955 and McElligotts are proud to have assisted in maintaining this historic piece of Tasmanian infrastructure. As part of the remediation process to keep Trevallyn Dam in good shape, our team stripped and re-lined three 30m x 1500mm conduits. This project required a quick turnaround, owing to rising dam levels.
Our team were required to abrasive blast the existing coal tar epoxy lining, which had heavy surface pitting, posing some challenges with surface preparation. From there, we repainted the conduit internals with a protective coating suited to the client’s needs. Our team had to deal with water leaks from stoplogs stream throughout the painting process, but we developed processes to ensure the quality was not compromised.
