What Poseidon Dredge & Marine does
Poseidon Dredge & Marine is a heavy civil marine construction company founded in 2013 and headquartered in Lake Worth Beach, Florida. The firm designs, permits, and builds waterfront infrastructure, with core service lines covering docks, seawalls, full marina development, and precision dredging, supplemented by pile driving and rock punching, breakwaters, beach renourishment, shoreline stabilization, rip-rap, fender systems, and tug and barge support. It serves two primary customer segments in Florida: residential waterfront property owners (private docks, seawalls, dredging) and commercial and governmental entities (marinas, bulkheads, navigational restoration). The company maintains FDOT, W/MSBE, and EDWOSB certifications, supporting access to state and federal contracting opportunities.
The underlying technology is a fleet of custom-fitted, in-house manufactured and maintained heavy civil marine equipment capable of handling projects up to 200 tons and 150 feet in length, paired with expertise across marine-grade hardwoods, composite decking (Evergrain), concrete, vinyl, aluminum, and steel sheet pile systems. The firm employs an internal safety training program and emphasizes precision dredging and regulatory-compliant execution. Operations extend across Florida, including Miami, Fort Lauderdale, Palm Beach, Palm Beach Gardens, Jupiter, and Stuart.
The business model is project-based and one-time in nature, with quote-driven pricing determined by scope, materials, site conditions, and regulatory requirements. Go-to-market is direct sales via the company website (pdmarineinc.com), phone (561-296-4991), email ([email protected]), and a presence across LinkedIn, Facebook, Instagram, and Twitter/X. The firm is privately held, has no disclosed institutional funding, no parent company, and no subsidiaries, and operates without public revenue disclosure.
