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.

I had a screen porch blow off during Hurricane Milton. One of the rebuilding efforts was to ensure the foundation under the wall that had supported the screen porch's attachment was secure. Helicon came and pumped in an expanding grout under the wall in question. Great job was done with precision measurements, and the area was left clean and neat. Well Done!
Rayton, Jay, Luis, Danny did a great job and left the house looking untouched. Very communicative through the installation process.
Excellent work, fast, efficient and at an affordable price. Thanks
From start to finish Helicon was patient, professional and understanding with Condo association slow deliberations. They finally months later received the approval. All the way Helicon executed a clean and neat install of remediation to soil and unstable earth around the condo. Great crew and good job. Tom
Helicon stabilized the soil behind our seawall earlier this spring. After a very wet summer, there was some new subsidence in three places along the seawall. They promptly returned, honoring their warranty, and inject additional material to reinforce the few spots that needed attention. Excellent customer service!
Jan and his team did an excellent job at our home yesterday. Our project had challenges and Jan kept up apprised and worked with us to make a decision for each section as needed. That communication led to an end result was as we expected.
The sales representative, Douglas, reviewed my home carefully, asked questions then prepared a drawing and contract. He was detailed in information and provided easily understood answers to questions. There was no pressure.

Follow up with associates was made in a timely manner by text, voice mail, and email. Tony easily answered my questions.

The techs arrived on time as scheduled. Professional, polite, focused on their tasks, respectful of neighbors and my home, treated the installation as if it were in their home.

Highly recommend Helicon!
Isaiah , Alfonzo, shelumiel, Antonio were absolutely outstanding! These guys take the job to another level! They went down till they hit rock! Totally relentless work ethic on this crew! Can recommend these guys a thousand times over - you will get only the best from this crew. Also, they were super polite and considerate! We highly recommend them and will always be grateful for the amazing experience with Helicon!!!
We are a Water Managment Special District in the state of Florida and when we started looking into repairing our outflow Dam that is responsible for 16 lakes, we took multiple bids and ended up choosing Helicon. It was a great choice! They were able to walk us through the steps of how they would be able to properly seal and help strengthen this outflow Dam that is essential to our community. Using their specialty hydrophilic foam, they were able to inject into our Dam sealing cracks and empty spaces that had eroded over time as well as pushing out water that had seeped in. they were able to accomplish this large undertaking within a day and they were able to instill a confidence in the structure that had not been there for decades. Not only would I recommend them to other government entities, companies, or individuals we are looking to work with them again in the future on the possibility of some different types of projects.
I contacted Helicon when I notice my garage floor was sinking next to the house. They responded by looking at my floor and said that chemical grout would lift and stabilize it. The crew that came to do the repair did a fantastic job!!! I would recommend this company!!!

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.

soil stabilization for foundation repairs

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.

soil stabilization for foundation repairs

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.
