Our Marine Construction Services in Greenwich

Dock Construction & Installation

We design and build custom docks tailored to Greenwich’s unique waterway conditions. From floating docks to fixed pier structures, we use marine-grade materials that resist corrosion, UV damage, and heavy tidal stress. Every dock we build is engineered for safety and long-term performance.

Seawall Construction & Repair

Erosion is a serious threat along Greenwich Harbor, Long Island Sound, and Byram Harbor. Our seawall solutions — including concrete, vinyl sheet pile, and riprap systems — protect your shoreline and property value. We handle everything from new seawall installation to full seawall restoration and cap repair.

Piling Installation

Proper pilings are the foundation of any marine structure. DRG Construction installs concrete, steel, and composite pilings engineered for Greenwich’s soil conditions and water depths. We use precision driving equipment to ensure every piling is set to spec.

Boat Lift Installation

Protect your vessel with a professionally installed boat lift. We carry and install a full range of boat lifts — from 2,000 lb to 80,000 lb capacity — suited for the boats and watercraft common to Greenwich’s waterways. Hydraulic, electric, and 4-post options available.
