South Florida Seawall Experts

Your seawall is the first line of defense between your waterfront property and the water. A failing seawall doesn't just look bad — it actively threatens your property's foundation, landscaping, and value. In South Florida's saltwater environment, seawalls take a constant beating from boat wakes, tidal movement, storm surge, and marine organisms.

JKT Marine Construction installs and repairs seawalls throughout Palm Beach County, Broward County, and Martin County. Our ownership team personally oversees every seawall project — from the initial structural assessment through final inspection. We handle all permitting including Palm Beach County, Broward County, SFWMD, FDEP, and Army Corps of Engineers.

⚠ Warning Signs Your Seawall Needs Attention

Don't wait until the damage is severe — early repair is almost always more cost-effective than full replacement.

Cracks or fractures in the wall face
Leaning or bowing toward the water
Soil erosion or sinkholes behind the wall
Water seeping through the wall
Damaged or missing seawall cap
Rust staining from corroding tie rods
Settlement or sinking near the wall
Wall pulling away from the cap

Our Seawall Services

We handle everything from minor repairs to complete seawall replacement — all with full permitting managed by our team.

Seawall Assessment & Inspection

We perform thorough structural assessments of your existing seawall — identifying cracks, movement, erosion, and tie rod corrosion. Free inspections for South Florida waterfront homeowners.

Seawall Cap Replacement

The seawall cap takes the most abuse from boat wakes and weather. We replace damaged or deteriorating caps with new concrete — one of the most cost-effective seawall repairs available.

Crack Repair & Injection

We fill and seal cracks in concrete seawalls using structural epoxy injection — stopping water infiltration and reinforcing the wall before damage progresses.

Tieback Anchor Installation

Tieback anchors stabilize a leaning or bowing seawall by connecting it to a deadman anchor buried behind the wall — often preventing the need for full replacement.

Full Seawall Replacement

When repair isn't enough, we install a complete new seawall — concrete, vinyl, or composite — engineered for your specific waterway conditions and permitted through all required agencies.

New Seawall Installation

We install new seawalls for properties that currently have no wall or inadequate shoreline protection — including on new construction, lot improvements, and waterfront expansions.

Seawall Materials We Install

We install all major seawall systems — and help you choose the right one for your waterway, budget, and long-term goals.

Concrete Seawalls

The most common seawall type in South Florida. Concrete offers excellent durability and strength — ideal for high-traffic waterways and Intracoastal-front properties with heavy boat wake exposure.

Vinyl Seawalls

Vinyl sheet pile seawalls are lightweight, corrosion-resistant, and install quickly. They're an excellent choice for canals and residential waterways with moderate wave action.

Composite Seawalls

Composite seawalls offer the best of both worlds — the strength of concrete and the corrosion resistance of vinyl. Ideal for South Florida's saltwater environment and high-UV conditions.

Aluminum Seawalls

Aluminum seawalls are lightweight, maintenance-free, and highly resistant to saltwater corrosion — a premium option for luxury waterfront properties.

Frequently Asked Questions

How much does seawall repair cost in South Florida?

Seawall repair costs vary widely depending on the type and extent of damage. Minor cap repairs and crack injection can cost $2,000–$8,000. Tieback anchor installation typically runs $5,000–$15,000. Full seawall replacement ranges from $25,000 to $75,000+ depending on length and material. JKT Marine provides free on-site assessments and detailed quotes.

Should I repair or replace my seawall?

It depends on the severity and type of damage. Cracks, cap damage, and minor leaning can often be repaired cost-effectively. Significant structural failure, severe bowing, or a wall that has already moved substantially usually requires full replacement. JKT Marine assesses every seawall individually and gives you an honest recommendation — repair when possible, replace when necessary.

Do I need a permit to repair a seawall in South Florida?

Yes — most seawall repair and all seawall replacement work requires permits from your county and potentially SFWMD, FDEP, and the Army Corps of Engineers. JKT Marine handles all permit filings on your behalf.

How long does a seawall last in South Florida?

A well-built concrete seawall in South Florida typically lasts 30 to 50 years with proper maintenance. Vinyl and composite walls can last 25 to 40 years. Regular inspections and early intervention on minor damage significantly extend seawall life and reduce long-term costs.
