Owning a waterfront property on Long Island comes with breathtaking views and direct access to the water — but it also comes with risk. Every year, erosion claims more land along Long Island’s south shore. Rising tides, boat wakes, and Nor’easters gradually eat away at the shoreline, threatening homes, docks, and property value.

That’s where marine construction comes in. From bulkheads and docks to shoreline restoration and piers, marine construction provides essential protection against erosion and ensures that waterfront properties remain safe and secure for decades.

At RC Wish Marine Construction, based in Amityville, we’ve spent decades building marine structures across Nassau and Suffolk counties that safeguard homes and businesses from the destructive power of water.

What is Erosion and Why is it a Problem on Long Island?

Erosion is the gradual wearing away of land caused by water movement, weather, and human activity. On Long Island, erosion is particularly severe because of:

• Tidal Fluctuations – Daily rising and falling tides weaken shoreline soil.

• Storm Surges – Nor’easters and hurricanes create waves that collapse unprotected land.

• Boat Traffic – Heavy canal and bay wakes accelerate erosion.

• Sea-Level Rise – Climate change steadily increases water levels.

Without intervention, erosion can cause:

• Loss of land and usable property space.

• Cracked or unstable foundations near the shoreline.

• Collapse of docks, bulkheads, and walkways.

• Significant reduction in property value.

The Role of Marine Construction in Erosion Control

Marine construction refers to the building of structures that interact with water — like docks, piers, bulkheads, and shoreline reinforcements. These structures are specifically designed to:

• Protect Land – Prevent soil from washing into waterways.

• Absorb Wave Energy – Reduce the force of wakes and storm surges.

• Stabilize Properties – Secure the shoreline and prevent collapse.

• Preserve Property Value – Maintain safe, usable waterfront access.

Key Marine Construction Methods for Erosion Protection

1. Bulkhead Construction & Repair

Bulkheads (also called seawalls) are vertical barriers built along the shoreline to stop erosion.

• Vinyl Bulkheads – Long-lasting, low-maintenance, and resistant to rot.

• Timber Bulkheads – Traditional look, affordable, but shorter lifespan.

• Steel Bulkheads – Heavy-duty option for commercial and high-impact areas.

• Concrete Bulkheads – Extremely strong, perfect for open bays.

2. Shoreline Restoration

Not all erosion solutions are walls — some involve restoring the shoreline naturally or with rock barriers.

• Riprap Revetments – Large stones placed along the shoreline to absorb wave energy.

• Living Shorelines – Use of plants, sand, and natural elements to slow erosion.

• Backfilling & Grading – Rebuilding eroded land and stabilizing it with reinforcement.

3. Helical Piles for Stability

Helical piles are screw-like anchors drilled deep into the ground to stabilize marine structures. They are especially useful for:

• Supporting docks and piers.

• Reinforcing failing bulkheads.

• Providing erosion resistance in sandy soils common on Long Island.

4. Dock & Pier Construction

While docks provide water access, they also contribute to shoreline stability when properly designed. A poorly installed dock can accelerate erosion, while a professional build can integrate with bulkheads and shoreline protection.

Benefits of Marine Construction for Long Island Homeowners

• Immediate Erosion Control – Stops land loss as soon as construction is complete.

• Storm Protection – Defends against hurricanes and Nor’easters.

• Property Value Increase – Homes with bulkheads and stable shorelines are worth more.

• Improved Waterfront Access – Safe docks, piers, and walkways.

• Peace of Mind – Protects your investment for generations.

Case Studies from Long Island

Massapequa Canal Property

A homeowner’s backyard was shrinking by the year due to boat wakes. RC Wish replaced an aging timber wall with a vinyl bulkhead, stopping erosion instantly and increasing property value.

Babylon Bayfront Home

After Hurricane Sandy, severe erosion left a home vulnerable to collapse. We installed a steel-reinforced bulkhead with riprap, securing the foundation and protecting against future storms.

Patchogue Shoreline Restoration

A property owner lost nearly 10 feet of land to erosion. Our team rebuilt the shoreline using backfill and riprap, restoring lost space and protecting the property for decades to come.

How Long Do Erosion Protection Structures Last?

• Timber Bulkheads – 15–20 years with maintenance.

• Vinyl Bulkheads – 30–40 years.

• Steel Bulkheads – 35–50 years.

• Concrete Bulkheads – 40+ years.

• Riprap & Living Shorelines – Decades, with proper upkeep.

What is Marine Construction?

Marine construction refers to the design and building of structures that exist in, on, or near the water. It combines engineering, construction, and environmental expertise to create safe, functional, and long-lasting waterfront features.

Unlike traditional construction, marine construction must account for tides, saltwater corrosion, storm surges, and soil conditions unique to coastal areas.

Common Types of Marine Construction on Long Island

1. Dock Building & Installation

Custom docks give homeowners safe, reliable access to their boats and the water. Options include fixed docks, floating docks, and multi-level docks with integrated boat lifts.
