Sedimentation Tank Refurbishment, ETP Carrum Downs
Secondary sedimentation tanks 17 & 18 at the Eastern Treatment Plant had experienced significant cement loss to the original uncoated concrete tank walls and all joint sealant had become defective.
Freyssinet identified the potential for asbestos in the original joint sealant and, prior to starting works, were able to optimise works to allow for the removal of the asbestos whilst maintaining program. The project involved life extension repairs, including concrete repair, coating, joint replacement and sealer.
Freyssinet Technical Services also carried out a condition assessment of steel structures providing the client with a comprehensive asset management plan.
