Living by the water in West Palm Beach, FL, is a dream for many. But with that dream comes the responsibility of protecting properties from the ever-present forces of nature. One of the most effective defenses is a seawall.
Discover our expert seawall services in West Palm Beach from Coast Seawall Dock & Boatlifts—designed for strength, longevity, and peace of mind.
What Are Seawalls?
Seawalls are marine infrastructure structures built along coastlines to protect land from the erosive force of waves, tides, and storm surges.
They act as a barrier between land and sea, playing a crucial role in coastal engineering and shoreline defense.
Common Types of Seawalls
- Vertical seawalls – Upright walls that deflect wave energy.
- Curved or stepped seawalls – Help dissipate wave energy more effectively.
- Revetments – Sloped structures made from rock or concrete.
- Bulkheads – Often used in residential marine construction.
Each type serves a purpose based on location, water dynamics, and seawall materials.
How Do Seawalls Protect Coastal Properties?
Seawalls form a first line of defense against environmental threats.
Storm Surge Protection
When tropical storms or hurricanes hit West Palm Beach, the rising sea level—known as storm surge—can cause immense flooding.
- Seawalls block or redirect water.
- Reduce risk of flood damage.
- Protect critical infrastructure and residential foundations.
Coastal Erosion Prevention
Erosion is a silent destroyer of coastal properties.
Without seawalls:
- Shorelines retreat over time.
- Property boundaries are compromised.
- Vegetation and soil stability are lost.
With seawalls:
- Erosion is slowed or halted.
- Property value is preserved.
- Long-term maintenance costs are reduced.
Why Coastal Erosion Is a Growing Threat in Florida
Due to rising sea levels and intense storms, Florida’s coastlines are particularly vulnerable.
According to studies:
- Over 70% of beaches in Florida face chronic erosion.
- West Palm Beach is at high risk due to its open coastline.
Infographic: Coastal Erosion in Florida
| Year | Average Beach Erosion (metres/year) | Major Weather Events |
| 2015 | 1.2 | Hurricane Erika |
| 2017 | 2.4 | Hurricane Irma |
| 2022 | 3.1 | Tropical Storm Nicole |
Pro Tip: Early installation of seawalls is far more cost-effective than emergency flood remediation.
The Science Behind Seawall Construction
At Coast Seawall Dock & Boatlifts, we use advanced coastal engineering techniques tailored to West Palm Beach’s unique shoreline conditions.
Key Seawall Materials
| Material | Pros | Cons |
| Concrete | Long lifespan, durable | Can be expensive to repair |
| Vinyl | Corrosion-resistant, low maintenance | Less strong under high wave stress |
| Steel | Ultra-strong, ideal for commercial use | Prone to rust without proper coating |
| Composite Panels | Lightweight and long-lasting | Higher initial investment |
Best Practices in Seawall Construction
- Conduct geotechnical soil testing.
- Use proper anchoring systems.
- Incorporate weep holes for drainage.
- Apply corrosion-resistant treatments.
Lifespan of Seawalls and Maintenance Tips
With quality seawall construction, your defense structure can last decades.
| Material Type | Average Lifespan |
| Concrete | 30–50 years |
| Vinyl | 20–30 years |
| Steel | 25–40 years |
Seawall Maintenance Checklist
- Inspect after every major storm.
- Look for cracks, bulging or rust.
- Keep weep holes free of debris.
- Monitor vegetation growth near the base.

Signs You Need a New or Repaired Seawall
Neglecting seawall issues can lead to total failure.
Warning Signs
- Tilting or leaning wall
- Crumbling concrete or exposed rebar
- Sinking soil or pools of water behind the wall
- Rust stains or warped vinyl panels
Expert Tip: If your seawall is more than 25 years old, get a professional inspection—even if no visible issues exist.
Seawalls vs. Other Shoreline Defense Methods
| Feature | Seawalls | Riprap | Living Shorelines |
| Erosion Control | Excellent | Good | Moderate |
| Flood Prevention | High | Moderate | Low |
| Aesthetic Appeal | Varies | Natural look | Very High |
| Maintenance Needs | Low to Medium | Low | High |
| Long-Term Durability | Excellent | Good | Moderate |
For properties with high-value structures near the shore, seawalls are the most reliable solution.
