Professional Seawall Construction for NY & FL Waterfronts
A seawall is the single most important structure protecting your waterfront property. Wind, waves, boat wakes, and storms steadily eat away at unprotected shorelines, and once erosion takes hold, land loss is expensive and difficult to reverse. DRG Construction designs and builds seawalls that stop erosion at the source, extend your usable property line, and protect your investment for decades.
We are a marine construction company specializing in waterfront construction throughout New York and Florida. From Long Island’s South Shore canals to the Intracoastal Waterway communities of South Florida and the Treasure Coast, our crews build seawalls engineered for the exact conditions of your shoreline — tidal range, wave exposure, soil type, and boat traffic included.
Seawall Materials We Build With
Every shoreline is different, so we build with the material that fits your site rather than a one-size-fits-all system:
- Vinyl seawalls — corrosion-proof, low-maintenance, and ideal for canal-front residential property in Florida and Long Island.
- Concrete seawalls and panels — heavy-duty protection for exposed shorelines, commercial marinas, and high-wave environments.
- Steel sheet pile seawalls — maximum structural strength for commercial waterfront construction and deep-water lots.
- Riprap and rock revetments — a natural-looking option that absorbs wave energy along open-water shorelines.
Our Seawall Construction Process
Sound sea wall construction is a sequence, not a single pour. Our process covers every phase:
- Shoreline evaluation — we assess erosion levels, soil conditions, water depth, and exposure before recommending a design.
- Engineering and permitting — seawalls typically require local, state, and sometimes Army Corps permits. We handle the paperwork so your project stays compliant.
- Site preparation and dewatering — we stage equipment, drive the shoreline, and manage water conditions for a stable build.
- Installation — sheet piles or panels are driven or set to design depth, then tied back and anchored for long-term stability.
- Drainage and backfill — proper weep holes and drainage prevent hydrostatic pressure, the leading cause of seawall failure.
- Cap, inspection, and cleanup — every wall is capped, inspected against the engineering spec, and the site is left clean.
Signs You Need a New Seawall
Replace or upgrade your seawall when you notice cracks or leaning panels, soil washing out behind the wall, voids or sinkholes near the shoreline, exposed rebar or rust streaks, or sections separating at the joints. Addressing these early is far less disruptive than a full emergency rebuild after a storm.
Why Waterfront Property Owners Choose DRG
DRG Construction is a waterfront construction company with a dedicated marine division — pile driving, dredging, dock building, and boat lift installation all in-house. That matters for seawall projects: when your wall needs tie-backs, a dock, or a boat lift integrated into the same structure, one crew handles the entire scope. We serve residential and commercial clients across New York (including Long Island, Queens, the Bronx, and Staten Island) and Florida (including the Treasure Coast, Palm Beaches, Broward, Miami-Dade, Naples, and Fort Myers).
