Whether it is sediment caused by ship traffic in harbors or the accumulation of mine tailings inland, these materials must be removed, transported, dewatered, stored or re-used. For example, each year an average of more than 100,000 cubic yards of dredged materials are removed from the Duluth-Superior Harbor. Marine Tech offers solid solutions to these dredging projects and is at the forefront of finding alternative solutions to dealing with the dredged materials.

Dredging and Surveys: Using the latest computer technology and state-of-the-art equipment, Marine Tech has been the company of choice for all dredging and survey applications that include maintenance dredging, environmental dredging or harbor surveys.

Of course we all know that the latest equipment and technology is useless without experienced personnel. For decades, Marine Tech has proven performance in dredging and survey work to the strictest specifications.
