BMC undertook the mammoth task of refurbishing the Bunbury Reservoir for AQWEST using cement injection. Over the years water had leaked out of the reservoir, creating massive voids under the floor and batter slabs.
BMC drilled core holes through the slab and were able to inject a combination of general purpose and microfine cement to fill the voids.
This recreated a solid footing for the reservoir, ensuring no future subsidence will occur.
