Great Lakes Dredge & Dock Corporation is the largest provider of dredging services in the United States and the only U.S. dredging company with significant international operations. The Company is also one of the largest U.S. providers of commercial and industrial demolition services, primarily in the Northeast. The Company owns a 50% interest in a marine sand mining operation in New Jersey supplying sand and aggregate for road and building construction. Great Lakes employs more than 150 degreed engineers, most specializing in civil and mechanical engineering, contributing to its 121-year history of never failing to complete a marine project.

To create, maintain and restore a wide variety of port and coastal assets – harbors, waterways, rivers, wetlands, beaches, and storm-eroded shores – we use our sizeable fleet of specialized dredging equipment to excavate and transport the full range of underwater soils, including silts, sands, clays and rock. Also, Great Lakes dredging and land reclamation is a significant and essential infrastructure activity.
