Seawall Repair

Florida’s coastal properties are constantly exposed to saltwater, storm surges, and shifting soil. Helicon is Florida’s trusted name in seawall repair, offering expert services that restore strength, prevent erosion, and preserve the long-term stability of your shoreline.

Florida Seawall Problem Signs

Washed-out areas or depressions in your yard often indicate erosion behind the seawall, usually from water escaping through cracks, panel joints, crevices, and tears in the failed filter fabric—typical are the root cause of the soil loss.

Soil Loss or Voids Behind the Wall

Washed-out areas or depressions in your yard often indicate erosion behind the seawall, usually from water escaping through cracks or clogged drainage systems.

Cracking in the Cap

Cracks along the concrete cap are early signs of stress or shifting, allowing water intrusion that accelerates deterioration.

Micropile Structural Support

Seawall Movement or Leaning

Any forward movement or tilting suggests a loss of structural integrity—often caused by soil instability leading to anchoring system failure, or by a clogged pressure relief valve system.

Spalling or Surface Deterioration

Chipped, flaking, or crumbling concrete (known as spalling) is a sign that the wall’s surface has been compromised by saltwater intrusion and aging materials.

Everyone I dealt with were very helpful. I feel confident Helicon and their material used are top notch used in fixing sinkholes. I had LRE previously but their material was inferior. I had to get Helicon to redo LRE’s work!
Great crew! Everything went as expected.

Prompt, courteous and thorough!
Highly recommend Helicon.
Great company to deal with! I had the pleasure of working with Doug. He assessed the situation and gave us a great solution to remedy our home that was having issues with settling. Helicon crew came out and did what they said. No sales pressure and I am very happy with the results. Time will tell but they have a great warranty. Give Doug a call! Thank you, Doug and Helicon.
I highly recommend Helicon for their services. Great job and well done!
More importantly I had a reason to call and seek some follow up service on the project. Helicon was responsive and resolved my request for additional stabilization of the soil under the drive way.
Thank you Helicon.
I was very pleased with Brett and his crew. They came out did a great job. Explained everything to me and job was done very well.

Seawall Repair Solutions for Your Florida Property

We use advanced, non-invasive methods that stabilize your seawall and extend its lifespan, without the need for full replacement. All our services are designed for Florida’s unique soil and coastal conditions.

Micropile Structural Support

Soil Stabilization

We inject high-strength polyurethane or chemical grout into loose or eroded soils behind the seawall. This strengthens the foundation, fills voids, and prevents further washout—helping restore structural integrity and protect against future erosion.

Underpin Foundations

Void Fill with Polyurethane

Eroded areas behind or beneath the seawall can create dangerous voids. We inject expanding polyurethane foam to fill these gaps, displace trapped water, and stabilize the ground—providing lasting support without excavation.

Underpin Foundations

Jet Filter Pressure Relief System

We install patented Jet Filters—an easy-to-clean, clog-resistant weep hole system that relieves water pressure behind the seawall while retaining soil. This reduces hydrostatic stress and helps prevent erosion-related damage to the wall structure.

What Causes Seawall Failure?

Florida’s harsh coastal conditions and problematic soils can wear down even well-built seawalls over time. Here are the most common culprits:

Micropile Structural Support

Broken Filter Fabric

The filter fabric behind your seawall is designed to keep soil in place while letting water pass through. Once it tears or deteriorates, soil escapes and erosion accelerates.

Clogged Weep Holes

Weep holes act as pressure relief points, allowing trapped water to drain while a filter retains soil. If they become blocked, water accumulates behind the wall, increasing hydrostatic pressure and risking structural failure.

Micropile Structural Support

Cracks and Openings in the Wall

Even small cracks let water seep through, carrying soil with it. This weakens the wall’s support and creates voids or sinkholes on the landward side.

Failing Tieback or Deadman Anchoring System

A tieback system holds the seawall in place against water and soil pressure. When it fails—due to corrosion, age, or soil movement—the wall can bow, lean, or collapse.

Seawall Repair FAQ

What causes seawalls to deteriorate?
Seawalls are constantly exposed to the forces of water, waves, and erosion, which can cause wear and tear over time. Common causes of seawall deterioration include water seepage, soil erosion, wave impact, and storm surges. Additionally, factors such as poor construction, age, and environmental conditions contribute to damage.
How do I know if my seawall needs repairs?
Signs that your seawall may need repairs include visible cracks, bulging or bowing sections, gaps between the seawall and the deck, and erosion around the base. You may also notice shifting soil, exposed rocks, or increasing vegetation growing near the seawall. If you notice any of these issues, it’s important to schedule an inspection with a professional.
What is the process for seawall repair?

The repair process depends on the extent of the damage. For minor cracks, we may use crack injection methods like polyurethane or epoxy to seal the gaps. 

Can a seawall be repaired without excavation?
Yes, many seawall repairs can be done with minimal excavation, especially when using techniques like Targeted Grout Injection. This method involves injecting a polyurethane resin into the affected areas to stabilize the soil and seal cracks without disturbing the existing structure.
How long does seawall repair take?
The timeline for seawall repairs depends on the severity of the damage and the repair method used. Minor repairs, such as crack injection or resin filling, may only take a few days. More extensive repairs, such as replacing sections of the wall or adding reinforcements, can take longer. Our team at Helicon works efficiently to minimize disruption to your property.
Will seawall repairs stop future erosion?
While seawall repairs can significantly reduce the risk of further erosion, ongoing maintenance is important to ensure the long-term effectiveness of the seawall. Adding protective measures such as riprap, geo-textile mats, or boulders can help further protect the seawall from wave energy and erosion.
How much do seawall repairs cost?
The cost of seawall repairs depends on the extent of the damage, the materials used, and the size of the seawall. Minor repairs like crack sealing may be more affordable, while larger projects involving soil replacement, reinforcement, or section replacement can be more expensive. Contact Helicon for an inspection and estimate tailored to your specific needs.
Are seawall repairs covered by insurance?
Insurance coverage for seawall repairs varies by policy and provider. Many standard homeowners’ policies do not cover seawall damage unless it’s due to a specific event like a storm. It’s recommended to review your policy or speak with your insurance company to understand your coverage options.
How can I prevent my seawall from needing frequent repairs?

Regular inspections and maintenance are key to prolonging the life of your seawall. Keeping debris away, managing erosion, and addressing small issues before they become larger problems can help maintain the structure. Additionally, adding protective measures like riprap can reduce the impact of waves and storms on your seawall.
