Headquartered in Oak Brook, Illinois, GLDD has a long history with Chicago’s shore infrastructure and river lock system. The company has since expanded and now operates on every domestic coastline, throughout many inland U.S. waterways, and in several foreign markets, most notably Bahrain, Qatar, and Brazil. In addition, Great Lakes Dredge & Dock possesses a fleet of smaller vessels that specialize in dredging challenging shallow water environments, such as lakes, reservoirs, rivers, and inland channels.

Since its founding, GLDD has been a leader in the building and maintenance of the nation’s navigation system, the protection of shorelines, the restoration of sensitive habitats, and the creation of critical aquatic infrastructure. We are committed to delivering innovative and high-quality workmanship to our clients while executing every project with a focus on employee safety.
