Fiberglass Seawall Panels: Stronger Than Your Average Wall
Professional Fiberglass Seawall Installation for Long Island Shorelines
Fiberglass seawall panels are the premier choice for the marine construction services provided by Pearce Marine Construction across Long Island.
Here is how our high-performance materials compare to traditional options for your shoreline project:
| Material | Typical Lifespan | Corrosion Resistance | Maintenance | Relative Cost Over Time |
|---|---|---|---|---|
| Fiberglass (FRP) | 75+ years | Excellent | Very low | Lowest |
| Vinyl (PVC) | Up to 40 years | Good | Low | Low–Moderate |
| Steel | Up to 50 years (coated) | Poor (rusts) | High | High |
| Wood (treated) | 15–25 years | Very poor | High | Moderate–High |
| Concrete | 30–50 years | Moderate (spalls) | Moderate | Moderate |
Pearce Marine Construction specializes in replacing failing steel, wood, and concrete seawalls in Nassau and Suffolk Counties with advanced FRP solutions. Steel rusts, wood rots, and concrete cracks over time, which is why we recommend Fiber Reinforced Polymer (FRP) for long-term durability.
Our FRP panels are engineered to last well over 75 years with minimal upkeep, rivaling steel in structural strength while remaining immune to corrosion. In 2026, Pearce Marine Construction continues to lead the industry in Southampton, West Islip, and West Hampton, ensuring your seawall is a long-term investment in your property.

The Engineering Superiority of FRP in Our Marine Construction Projects
Pearce Marine Construction utilizes Fiber Reinforced Polymer (FRP) composites to deliver high-performance marine infrastructure. This material, trusted in aerospace for its strength-to-weight ratio, is the standard for our projects in the Great South Bay.
Our construction process involves high-grade vinyl ester resin panels created through pultrusion, ensuring incredible tensile strength and resistance to soil pressure. Unlike traditional materials, the Fiberglass Seawalls & Accessories - Lee Composites we install are predicted to have a 75+ year service life because they are chemically inert.
We ensure all installations in Babylon and Bayshore include advanced UV protection to prevent degradation. For more details on our professional methods, see our More info about seawall construction.
Why Pearce Marine Construction Recommends Fiberglass Over Traditional Materials
- Steel: We replace rusted steel walls that require constant, expensive maintenance.
- Wood: We provide solutions that are immune to marine borers like Gribbles and Shipworms, which destroy timber bulkheads.
- Concrete: Our FRP solutions avoid the internal rebar corrosion and spalling common in concrete structures.
- Vinyl: While we offer vinyl, we recommend fiberglass for high-energy environments requiring superior impact resistance.
