Underwater concreting

We specialize in pouring concrete underwater. Underwater concreting is often used for permanent repairs, structure installations and other applications in today’s marine construction industry.  When subsoil water cannot be pumped out of the building site our divers can be employed to pour concrete underwater. This prevents the surrounding area from settling and risky situations are avoided.

Examples of underwater concreting uses are:

•    Structure foundations and slabs
•    Embankment stabilisation
•    Pier and Pylon footings and supplement
•    Pipeline and cable encasements
•    Boat Ramps
