Concrete Seawall Repair in Galveston, TX
Galveston's marine environment is harsh on concrete. Saltwater intrusion, wave action, and Texas Gulf Coast storms take a toll. Our matched pros restore structural integrity with proven marine-grade repair techniques designed for coastal conditions.
Concrete Repair Methods
Epoxy Crack Injection
Low-viscosity epoxy injected under pressure into cracks to bond the concrete back together at a molecular level. Restores structural strength and prevents water intrusion. Used for cracks from hairline up to 1/4 inch wide. The repaired section is often stronger than the surrounding concrete.
Spall & Delamination Repair
Removal of loose, deteriorated concrete down to sound substrate. Corroded rebar is cleaned, treated with rust inhibitor, and coated. The area is then patched with marine-grade polymer-modified repair mortar that bonds to existing concrete and resists saltwater attack.
Hydrodemolition & Overlay
For severely deteriorated walls, high-pressure water jets remove damaged concrete without harming sound material or rebar. A new structural overlay of high-performance marine concrete is then applied. The most durable repair method for Galveston's aggressive saltwater environment.
Cathodic Protection
For walls with widespread rebar corrosion. A sacrificial anode system is embedded in the repair areas to attract corrosion current away from the steel reinforcement. Extends the life of repairs by decades in saltwater environments.
Signs Your Concrete Seawall Needs Repair
Rust-colored stains running down the wall face indicate corroding rebar inside the concrete. Spalling (chunks of concrete breaking away) exposes rebar to more salt and accelerates deterioration. Hollow-sounding areas when tapped mean the concrete has delaminated from the rebar. Cracks wider than 1/8 inch allow saltwater to reach the steel. If you see any of these signs, call for an assessment — the damage spreads exponentially once it starts.
What's Included
Damage Assessment
Sounding and visual survey to map all deteriorated areas and determine the appropriate repair method for each.
Surface Preparation
Removal of unsound concrete, high-pressure washing to remove salt and marine growth, and rebar treatment.
Structural Repair
Crack injection, spall patching, or full overlay using marine-grade materials rated for continuous saltwater exposure.
Protective Coating
Application of a waterproof, chloride-resistant coating to protect the repaired areas from future saltwater intrusion.
Concrete Seawall Repair Costs in Galveston
Concrete seawall repair costs vary based on damage extent. Minor crack injection and spall repair: $2,000–$8,000 for a typical residential seawall section. Moderate repairs including rebar treatment and patching: $8,000–$25,000. Major rehabilitation with hydrodemolition and structural overlay: $25,000–$75,000+. These are Galveston-area estimates — every project requires an on-site assessment for an accurate quote. Call (832) 852-0497 to get matched with a concrete seawall repair specialist.
