Florida Sinkhole Warning Signs

Early detection is key. If you notice any of these warning signs around your home or property, your soil may be unstable—possibly due to a developing sinkhole:

Underpin Foundations

Cracks in Foundation or Walls

Horizontal or stair-step cracks on interior or exterior walls may signal movement or loss of ground support beneath the foundation.

Underpin Foundations

Uneven or Sinking Floors

A shifting foundation often causes floors to become sloped, spongy, or visibly sunken in certain areas.

Underpin Foundations

Sticking Doors & Windows

If doors or windows suddenly begin to jam or won’t close properly, the building frame may be shifting due to soil movement.

Micropile Structural Support

Drywall Cracks or Ceiling Gaps

Cracks along drywall seams, or separations between walls and ceilings, can indicate settlement beneath the structure.

Micropile Structural Support

Tilting Fences or Exterior Walls

Leaning fences or buckling exterior walls are signs of uneven ground movement that may be linked to underground voids.

Underpin Foundations

Pooling Water or Sudden Depressions

Surface water that collects in new low spots—or sudden, unexplained holes in your yard—can point to subsurface soil collapse.

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!!!
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!
There's no words to express how grateful I am with Helicon service. They did an awesome job with my house. My house had foundation issues and Helicon fixed the problem. Thank you Bradford, Rhonda, the head manager, the Forman and his partner. The service and treatment was exceptional. I would recommend them to any one who has foundation issues. God bless you all.
Elias, Shemy, Alfonzo did a great job lifting the corner of our house. I wouldn’t hesitate to use them again.
Clearwater Community Church had a foundation issue stemming from multiple building modifications that included foundations being poured at different times and joined. In one of our spaces there was a crack the extended the length of the room with an elevation difference at the worse place approaching an inch in vertical displacement. We requested input and quotes from several contractors, selecting Helicon based on their insight to our problem, their expertise, their proposed solution and price. In the space with the crack and damaged foundation using their expanding foam injection process, they were able to fill the voids under the foundation, stabilize the soils beneath and raise the dropped portion of the foundation to be level across the crack. (See photo.) In an adjacent space that showed on elevation differences across the surface of the foundation they used the same expanding foam process to stabilize the underlying soils to prevent potential future issues. We have since laid new flooring and are satisfied with the work and Helicon's five-year warranty on the work.
Reliable, professional and easy to work with.
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!

Sinkhole Repair Solutions from Helicon

We offer engineered solutions to permanently stabilize sinkholes and restore the integrity of your foundation. Each repair strategy is customized for your site conditions, soil composition, and property type and backed by decades of experience and robust warranties.

compaction grouting

Compaction Grouting

We inject a thick, high-strength grout mixture into underground voids. As the material is pumped under pressure it forms a bulb. The bulb grows outward, pushing the surrounding soils away, fillings gaps, densifying the soil and stabilizing the ground to prevent further movement or collapse.

soil stabilization for foundation repairs

Chemical Grouting

Ideal for finer soils, this process uses expansive, water-reactive chemical grout to bind loose particles and strengthen weak areas—ensuring soil won’t shift or erode beneath the structure.

soil stabilization for foundation repairs

Permeation Grouting

Low-viscosity polyurethane is injected to permeate and solidify porous soils. This creates a dense, durable soil matrix that resists washout and reinforces load-bearing capacity.

Micropile Structural Support

Underpinning

To provide permanent structural support, we install deep foundation elements (such as drilled-in piers or push piers) that transfer the weight of your home or building to stable load-bearing strata below the compromised soil.

What Causes Sinkholes in Florida?

Florida is especially prone to sinkholes due to its geologic makeup and environmental factors. Here’s what typically triggers them:

  • Limestone Bedrock – Much of Florida sits on a foundation of soft limestone that slowly dissolves over time from exposure to acidic rainwater, creating underground cavities that can eventually collapse.
  • Fluctuating Water Tables – Periods of drought can reduce groundwater support, while heavy rains or flooding can overload weakened areas—both of which contribute to sinkhole formation.
  • Human Activity – Construction, well drilling, mining, and excessive groundwater pumping all disrupt the underground balance. Lowered water tables and added surface pressure increase sinkhole risk.
  • Natural Erosion – In addition to chemical erosion, flowing underground water can physically remove support materials—causing voids to grow larger until they suddenly collapse.

How do I know if I have a sinkhole?
The only sure way to know you have a sinkhole is to consult with a professional. Feel free to contact us to point you in the right direction.
What causes sinkholes to form?
Sinkholes typically form in karst terrain when surface sediments collapse into underground cavities in limestone bedrock. Groundwater slowly dissolves the limestone over time, creating voids. When these cavities grow large enough, the overlying earth can no longer support the weight, causing it to collapse. Sometimes, a depression forms instead of a collapse as surface sediments gradually settle into the void.

Florida is primarily underlain by karst terrain, which includes sinkholes, caves, and springs. While not all sinkholes cause immediate damage, they can be a significant issue when they affect infrastructure. The state’s geology contains many cavities, but few collapses to cause real-world problems. There are different types of sinkholes in Florida, including solution sinkholes, cover-subsidence sinkholes, and cover-collapse sinkholes, which occur depending on the thickness of surface sediments.

How long does a sinkhole continue to grow?
Sinkholes can grow rapidly. Once a cavity is large enough, the earth above it may collapse quickly, with initial damage occurring in minutes to hours. The surrounding sediments may continue to shift for a day or more. In less dramatic cases, such as cover-subsidence sinkholes, the depression may take years to fully form.
Where can I find Florida laws related to sinkholes?
You can search Florida statutes by typing “sinkhole” into the search box on the official website. The majority of these laws are related to insurance and sinkholes, such as Florida Statute 627.706.
Is there a database of all sinkholes in Florida?
No comprehensive database of sinkholes exists, but the Florida Geological Survey (FGS) maintains a record of reported subsidence incidents. These incidents include sinkholes and similar events, though most have not been verified by professionals. The data covers incidents reported since 1954.
What is a subsidence incident?
A subsidence incident refers to depressions or ground surface settling that may resemble sinkholes but are caused by different factors. These can include issues like decomposing organic material, faulty drainage systems, or improperly compacted soil. Only professional geologists can determine whether an incident is a true sinkhole.
Where can I find information on subsidence incidents?
You can access subsidence incident reports from the Florida Department of Environmental Protection’s Map Direct website or GIS Open Data Portal.
Are there safe areas in Florida with no risk of sinkholes?
Since Florida is largely made up of carbonate rocks, sinkholes could theoretically form anywhere. However, the risk is higher in areas where limestone is closer to the surface. Properties in karst regions are more likely to experience sinkhole activity, so it’s essential to learn about the local geology when purchasing land.
What happened to the Florida Sinkhole Research Institute (FSRI)?
The FSRI was defunded in the early 1990s, and its database was transferred to the Florida Geological Survey. Today, the FGS continues to track sinkhole data and provide valuable resources about sinkhole risks in Florida.
