Underwater concreting is a critical concreting process performed for offshore construction. It involves the process of carefully placing fresh concrete underwater. As construction in water results in many difficulties, the start to end of an underwater construction requires special care, supervision and planning. For example, the construction of the foundation and piles to support the bridge crossing a river, or a dock construction.
Lifting a vessel out of the water for inspection or maintenance is a very expensive and is often unnecessary. Props, anodes, inlets, rudders etc can usually be inspected, cleaned or replaced underwater at a fraction of the cost. Abyss also offers specialist services such as Invasive Species Surveys by qualified Marine Biologists, a requirement to enter and leave some Australian Ports.
Piles and structures are cleaned with either HP water jetting, hydraulic barnacle buster or hand tools to allow inspection and maintenance to be undertaken. We are familiar with WSCAM inspection requirement and Transport and Main Roads, Structures Inspection criteria.
