Shuttering and Underpinning

Seawork undertook the design and site work to stabilise a retaining wall that had scoured and was failing. Galvanised steel interlocking trench sheets were driven into the seabed and restrained with steel beams to provide a steel box shutter. The work could only be undertaken at low water spring tides and once installed 60 cube of concrete was then pumped and allowed to flow into all the voids to establish a solid foundation.
