FRASERBURGH HARBOUR JETTY REPAIRS
Undermining of quay wall had led to loss of infill and settlement of concrete surfacing. Dive inspection revealed urgent repair required as large mass concrete walls had no foundations remaining. Temporary tie and support system across pier designed to allow work to be undertaken without walls collapsing; excavation of harbour bed and construction of new concrete foundations, restoring wall stability.
