Crack & Joint Repair
Epoxy injection and hydraulic cement sealing of structural cracks and failed panel joints to stop water and soil migration through your seawall.
Seawall Repairs & Concrete Seawall Repair in South Florida
Structural repairs for concrete seawalls and caps: we stop erosion, seal cracks, and restore your waterfront before small problems become catastrophic failures.
Seawall Repair
Seawall Repairs That Stop the Damage Before It Gets Worse
Seawall damage gets worse if you ignore it. A small crack lets water through, which washes soil out behind the wall. Eventually the wall loses support and fails.
We repair concrete and vinyl seawalls across Broward and Palm Beach counties. Cracked concrete panels, spalling caps, failing tie-backs, voids opening up behind the wall, we have seen it all. We find what is actually causing the damage and fix it properly, not just patch the surface. Our crew is licensed for marine construction and we use materials that hold up in saltwater. Need a brand-new wall instead? See our concrete seawall construction page.

Repair Services
Seawall Repair Services We Provide
Panel Replacement
Full or partial replacement of failed, shattered, or severely deteriorated concrete and vinyl seawall panels using marine-grade materials.
Tie-Back Reinforcement
Installation of galvanized or stainless steel tie-back rod and deadman anchor systems to stop bowing and restore structural stability.
Cap Repair & Replacement
Concrete cap restoration, reinforcement, and full replacement to reseal the top of your seawall from water infiltration and weathering.
Void & Sinkhole Repair
Polyurethane foam injection to fill voids and cavities behind the wall caused by water migration, preventing catastrophic soil loss.
Erosion Stabilization
Rip-rap placement and geotextile fabric installation to shore up eroded sections and prevent continued land loss along your seawall base.
See a recent NCFI polyurethane seawall injection in Boca Raton project.
Seawall Cap Repair
Seawall Cap Repair & Replacement
The cap is the reinforced concrete beam along the top of your seawall. It ties the panels together and keeps water out of the wall. In South Florida it is usually the first part of a concrete seawall to fail.
Salt air and tidal splash corrode the rebar inside the cap. The steel expands, the concrete spalls and cracks, and water starts getting behind the panels. Left alone, a failing cap leads to panel movement, soil loss, and a much more expensive repair.
- Spall & crack repair — Chip out loose concrete, treat exposed rebar with a corrosion inhibitor, and patch with marine-grade repair mortar.
- Cap resurfacing — Bonded overlay to restore a uniform, sealed top surface on caps with widespread surface deterioration but sound structure.
- Partial cap replacement — Remove and re-pour failed sections with new rebar doweled into the existing cap and panels.
- Full cap replacement — Demolish the old cap and pour a new reinforced cap at current NAVD88 elevation, tying the panels back together.
Want the details first? Read our seawall cap repair guide on cracks, spalling, and when to replace the cap. Not sure whether yours is repairable? Book a seawall inspection and we will document the cap, panels, and tie-backs and give you both a repair and a replacement price.
Bulkhead Repair
Seawall & Bulkhead Repair
In South Florida "seawall" and "bulkhead" mean the same retaining wall along your canal, lake, or Intracoastal frontage. We repair both concrete and vinyl bulkheads using the same methods described above: crack and joint injection, new tie-backs and deadman anchors, panel replacement, cap repair, and polyurethane void filling behind the wall.
Older wood bulkheads need a different approach, including replacing rotted whalers and sheathing or sleeving the wall in vinyl. See our bulkhead repair page for wood, vinyl, and concrete bulkhead options, or book a seawall inspection for a repair-or-replace recommendation.
Warning Signs
Signs Your Seawall Needs Repair Now
Seawall damage escalates quickly in South Florida's marine environment. These warning signs indicate active structural problems that require professional attention.
- Horizontal or diagonal cracks running through panels or the concrete cap
- Spalling, rust stains, or exposed rebar along the seawall cap
- The wall is visibly leaning, bowing, or deflecting toward the water
- Soil or sand washing through joints and into the waterway
- Sinkholes or depressions forming in the yard behind the wall
- Water seeping through the wall or pooling behind it during high tide
Our Process
How We Repair Your Seawall
01
Inspect
We perform a thorough evaluation of your seawall above and below the waterline, documenting all damage, deflection measurements, and soil conditions.
02
Diagnose
We identify the root cause of the failure, whether hydrostatic pressure, void formation, material degradation, or structural overload.
03
Propose
You receive a clear written repair scope with itemized costs, timeline, and an honest recommendation on repair vs. full replacement.
04
Repair
Our licensed marine crew executes the repair using the right technique and materials, not a temporary patch.
05
Verify
Final inspection to confirm structural integrity, site cleanup, and documentation for your records and insurance.
FAQ
Seawall Repair Questions & Answers
Minor to moderate damage, such as small cracks, isolated void areas, a deteriorating cap, or minor leaning, can usually be repaired cost-effectively. If your wall has widespread panel failure, is leaning more than 2 to 3 inches, is older than 35 to 40 years with significant corrosion, or has failed tie-back systems throughout, replacement is usually more economical long-term. We assess this honestly during your free inspection and give you both options with pricing.
Most seawall repair projects take 1 to 5 days depending on scope. Crack injection and cap repairs can be completed in a single day. Tie-back installation or panel replacement typically takes 2 to 4 days. Full-scale repairs on longer seawall sections may take up to a week. We provide a specific timeline in every proposal before work begins.
Minor cosmetic repairs often do not require permits, but any structural work, such as tie-back installation, panel replacement, cap replacement, or repairs affecting the wall's footprint, requires permits in Broward and Palm Beach counties. We determine the permitting requirements during assessment and handle all filings as part of our repair service at no extra charge.
The most common causes are age and material degradation, inadequate original design, salt corrosion attacking reinforcement steel, hydrostatic pressure from heavy rainfall or tidal fluctuation, erosion voiding the soil behind the wall, and storm surge forces. In South Florida's limestone and sandy soil environment, void formation behind the wall is especially common and accelerates failure rapidly once it begins.
Yes, when addressed properly. We use high-pressure epoxy injection and hydraulic cement to fill and seal structural cracks from the inside out. For active seepage, hydrophilic polyurethane grout expands on contact with water to create a watertight seal. These repairs are durable and long-lasting when the underlying cause (void, pressure, movement) is also addressed, which is always part of our repair scope.
Usually, yes. If the panels and tie-backs are sound, we can chip out the failed concrete, treat exposed rebar, and re-pour or resurface the cap on its own. Spalling, hairline cracks, and small sections of broken cap are repairable in a day or two. If the cap is separating from the panels, has widespread rebar corrosion, or sits below current NAVD88 elevation requirements, a full cap replacement is the better long-term option and can often be done without disturbing the panels below.
Not in South Florida. Bulkhead and seawall are two names for the same structure. Concrete and vinyl bulkheads get the same repairs as seawalls: crack injection, tie-backs, cap repair, panel replacement, and void filling. Wood bulkheads usually need rotted boards and whalers replaced or a vinyl sleeve. We inspect the wall and quote both repair and replacement.
