Underwater Surveys

Dredging Services has a working relationship with Underwater Surveys (PTY) Ltd. which allows us to offer our clients professional pre and post-dredging survey services. This partnership has greatly enhanced our dredging work by making available state-of-the-art technology to determine sub-bottom profiles, volumes to be dredged, as well as to provide a 3D image of the dredged area after completion of the dredging work. The client can thereby have a very accurate determination of the actual volumes dredged.

Dredging surveys are important to prevent differences between the invoiced amount and actual volumes dredged, since dredging work is normally priced per cubic meter dredged.

Underwater Surveys is a hydrographic and engineering surveying company that serves the Sub­-Saharan and Island markets and provides full turn­key solutions for offshore, near­shore and inland surveys. Services include bathymetric, oceanographic, hydrographic, exploration, dredging surveys, and positioning solutions.
