Coastal Stability Starts at the Shoreline

Protecting Your Waterfront Property

Seawalls play a critical role in stabilizing shorelines and protecting waterfront properties from erosion, soil displacement, and long-term structural deterioration. Over time, tides, storm surge, saltwater exposure, and hydrostatic pressure can compromise aging seawalls. When that happens, replacement or new installation is the most reliable long-term solution. Ultramarine designs and installs seawalls engineered to restore shoreline stability and protect the long-term integrity of your waterfront property.

Our Seawall Systems

Every shoreline calls for a different solution. We build with various seawall materials, each suited to specific site conditions, water depth, and budget.

Here is a closer look at what each one is made of.

Vinyl

Corrosion-proof and cost-effective, vinyl shrugs off rot, rust, and marine borers with little upkeep. The proven, sensible default for residential waterfronts — strong value, no surprises.

Composite (FRP)

Highest strength-to-weight of any system, fully corrosion-proof, and virtually maintenance-free. For owners who want the best wall on the water and never want to think about it again.

Steel

Galvanized sheet pile built for the heaviest loads, the deepest water, and the tallest walls. What commercial and municipal projects turn to when nothing lighter will hold.

Concrete

King-pile-and-panel construction with a clean, flat face and the mass to match. A substantial, traditional wall for owners who want their shoreline to feel permanent.

Rip Rap

Not a barrier but a sloped bed of granite armor stone that absorbs waves instead of fighting them. Natural-looking and economical — ideal where the shoreline has room to slope.
