Preserving Your Seawall Before Small Problems Become Major Repairs

Protecting Your Waterfront Property

Seawall damage often begins below the surface. Soil movement, water pressure, and long-term exposure can gradually weaken the structure.
Without proper inspection and timely repair, minor issues can lead to erosion, instability, and costly replacement.

Ultramarine helps identify problems early and restore the strength of your seawall before they escalate.

Built to Perform in Coastal Environments

Engineered for Long-Term Performance

Ultramarine repair solutions are designed to address the real conditions affecting your seawall.

Inspection & Repair Services

Seawall Inspections
Evaluate structural integrity, soil conditions, and early signs of failure.

Structural Repairs
Stabilize compromised sections and restore strength.

Void Filling & Soil Stabilization
Address erosion and loss of support behind the wall.

Crack & Joint Sealing
Seal cracks and separated seams with SeamShield, our proprietary marine-grade barrier that stops soil loss and water intrusion at the source.

From evaluation to repair, our team provides clear recommendations and executes the work with precision.

Common Seawall Warning Signs

Spot Issues Before They Become Major Repairs

Cracked Panels

Cracks running through seawall panels can let water and soil pass through. Catching them early prevents erosion behind the wall.

Leaning or Bowing Wall

A seawall tilting toward the water or bowing inward signals structural stress. The longer it’s ignored, the more costly the fix.

Soil Loss Behind Wall

Sinking landscaping, depressions, or voids near the cap point to soil washing out from behind the seawall.

Cracked or Crumbling Cap

Damage to the seawall cap exposes the structure underneath to saltwater intrusion and accelerates failure.

Introducing SeamShield

A Targeted Solution for Soil Loss and Water Infiltration

When a seawall is compromised by cracks in the vertical panels or separated seams, the real damage is happening behind the wall. Soil washes through the openings with every tide cycle, leaving voids that show up as depressions, sinkholes, and eventually structural failure.

SeamShield is an engineered solution designed to stop that process. Made from marine-grade starboard, SeamShield strips are anchored across compromised seams and cracks with stainless steel screws, sealed with hydraulic cement, and paired with jet filters that relieve hydrostatic pressure on the land side. The result is a wall that keeps soil in, lets water drain properly, and adds years of life to a seawall that would otherwise be on the path to replacement.

SeamShield is one of several solutions we use, and the right fit depends on the condition of your wall. For seawalls with intact panels but failing seams, it is often the most effective and least invasive option available.

A Practical Approach to Every Project

No two waterfront properties are the same. Site conditions, water exposure, soil composition, and structural history all factor into the right solution, and we take the time to understand each one before recommending a course of action.

We focus on identifying the root of the problem, not just what’s visible on the surface. Whether that means a targeted repair, a full replacement, or a new build from the ground up, our recommendations are based on what your property actually needs.

Our goal is simple: get it right the first time.
