In shallow and deeper water, Rockwheels are a safe and effective choice - whether for harbour foundation work, building canals or dredging hard material and lowering river beds. No modification is necessary.

While a hammer, for underwater use, has to be modified with pressurised air systems, Rockwheels can be freely used in the water at any time, and with greater precision.

GPS systems can increase the precision further when working with poor visibility.
