Seawalls vs. Bulkheads: Which is Right for Your Property?

Protecting your waterfront property in areas like Ocean Isle Beach, Holden Beach, and Sunset Beach is a top priority. The constant movement of water, from gentle tides to powerful storm surges, can cause significant soil erosion, threatening the stability of your land and the structures on it. Two of the most effective solutions for shoreline protection are seawalls and bulkheads.

While the terms are often used interchangeably, they serve distinct purposes and are designed for different conditions. Understanding the difference is key to making the best investment for your property. This guide will walk you through a comparison of seawalls and bulkheads, helping you decide which is the right fit for your needs.

Seawalls

Seawalls are solid, engineered structures built to withstand the force of waves from oceans or large lakes. Made from materials like reinforced concrete and steel, they provide top-tier erosion control and flood protection—ideal for properties exposed to strong wave action. Seawalls tend to require higher investment but offer decades of protection and can increase property value.

Best for: Oceanfront or high-energy shorelines where wave impact and flooding are major risks.

Bulkheads

Bulkheads are vertical retaining walls designed mainly to prevent soil erosion along calmer waters like canals and rivers. Often constructed from vinyl or, less commonly, treated wood, bulkheads help create a stable water’s edge and usable land but aren’t built for direct wave impact.

Best for: Canals, bays, and protected waterways where the main concern is soil retention.

Material Choices

• Vinyl: Long-lasting, low-maintenance, and resistant to rot—excellent for bulkheads.
• Treated Wood: Offers a natural look but is less durable, requiring more upkeep.
• Concrete & Steel: Chosen for seawalls where strength and longevity are critical.



Making Your Choice

Opt for a seawall for direct ocean exposure and maximum protection, or a bulkhead for sheltered locations focused on soil stability. Both benefit from professional installation using quality materials.
