Concrete Seawall Construction & Repair

Reinforced concrete seawall systems engineered for high-exposure and commercial waterfront properties, built with epoxy-coated rebar to resist South Florida's saltwater environment.

Concrete Seawalls

Engineered Concrete Built to Last


Concrete seawalls remain the preferred choice for commercial properties, high-exposure shorelines, and sites where maximum structural mass is required.

We build and repair reinforced concrete seawalls using epoxy-coated rebar, marine-grade concrete mixes, and designs worked out for your site's conditions. We also repair existing concrete seawalls, from crack injection and spall remediation to full cap replacement and tie-back reinforcement, using proper structural methods rather than cosmetic patches that fail within a few seasons.

Our Services

Concrete Seawall Services


New Concrete Seawall Construction

Engineered reinforced concrete seawall systems with epoxy-coated rebar, designed for commercial, high-exposure, or heavy-load waterfront applications.

Concrete Panel Repair

Structural crack injection, spall repair, and panel restoration to extend the life of existing concrete seawalls and restore watertight integrity.

Cap Replacement

Reinforced concrete cap removal and replacement with properly elevated, rebar-reinforced pours that meet current NAVD88 code requirements.

Rebar Corrosion Remediation

Exposure of corroded rebar, application of corrosion inhibitors, and concrete patching to halt the expansion damage that causes seawall spalling.

Tie-Back Reinforcement

Addition of galvanized or stainless steel tie-back and deadman anchor systems to stabilize bowing or leaning concrete seawall sections.

Void & Sinkhole Filling

Polyurethane injection that fills voids and cavities behind concrete seawalls and stops the soil migration that precedes catastrophic wall failure.

Warning Signs

Concrete Seawall Warning Signs


Concrete seawall damage is often visible on the surface but structural failure is occurring from within. These signs indicate your concrete seawall needs professional attention.

  • Horizontal cracks running along the face of the wall, a sign of bending stress and potential structural failure
  • Rust stains or brown streaking on the wall surface indicating corroding interior rebar
  • Spalling or chunking concrete where sections of the wall face are breaking away
  • The wall is visibly leaning or bowing more than an inch or two from plumb
  • Depressions or sinkholes forming in the yard directly behind the seawall
Our Process

How We Handle Your Concrete Seawall


01

Inspect

We assess your concrete seawall's condition including crack mapping, deflection measurement, rebar corrosion evaluation, and soil void detection.

02

Design

We engineer the repair or replacement solution specifying concrete mix, rebar grade and coating, tie-back requirements, and NAVD88 cap elevation.

03

Permit

We manage all required permits from city, county, and DEP agencies, including structural drawings from our engineering team.

04

Build

Our licensed crew performs the work using marine-grade concrete, epoxy-coated rebar, and proven construction methods appropriate for South Florida's environment.

05

Handover

Final inspection, as-built documentation, warranty package, and maintenance guidance to maximize the life of your concrete seawall.

FAQ

Concrete Seawall Questions & Answers


A properly constructed reinforced concrete seawall in South Florida typically lasts 25 to 40 years before requiring significant structural attention. The primary failure mechanism is saltwater penetrating to the steel rebar, causing corrosion and expansion that cracks and spalls the concrete. Using epoxy-coated or stainless rebar in new construction, and addressing small cracks promptly, substantially extends service life.
Yes, in many cases. Isolated panel cracks, spalling sections, deteriorated caps, and leaning walls with intact foundations can be repaired at significantly lower cost than replacement. However, widespread rebar corrosion throughout the wall, severe panel fracturing, or walls that are more than 35 to 40 years old with multiple failure points are usually better candidates for replacement. We evaluate this honestly during your free inspection.
The most common cause in South Florida is rebar corrosion. When saltwater penetrates through small cracks or porous concrete, it reaches the steel reinforcement. Corroding steel expands and cracks the surrounding concrete from within, a process called spalling. Secondary causes include hydrostatic pressure from heavy rainfall, inadequate original design, soil void formation behind the wall, and impact damage.
For most South Florida residential waterfront properties, vinyl sheet pile is the better long-term choice due to its immunity to saltwater corrosion and marine borers. Concrete is preferred for high-traffic commercial docks, properties with extreme wave exposure, heavy equipment loading areas, or sites where the greater mass of concrete is structurally advantageous. A third option, the Truline hybrid wall, pairs a vinyl form with a steel-reinforced concrete core, giving you concrete strength without exposing the steel to salt water. We recommend the right system for your specific site during a free consultation.
Concrete seawall repair costs depend heavily on the scope. Crack injection repairs on short sections can start around $2,000 to $5,000. Cap replacement typically runs $150 to $300 per linear foot. Full structural repairs with tie-back installation range from $300 to $700 per linear foot. We provide detailed itemized estimates after inspection so you know exactly what you're paying for.
