Florida Sinkholes
Sinkholes can continue growing for years—or even decades—depending on what’s happening beneath the surface. In many cases, a sinkhole will only stop expanding once the underground void is fully stabilized or collapses completely.
For homeowners in Florida, understanding when a sinkhole stops growing is critical to protecting your property and foundation.
Why Do Sinkholes Keep Growing?
Sinkholes form when water erodes limestone beneath the ground, creating empty spaces (voids). Over time, the soil above those voids weakens and eventually collapses.
In Florida, this process happens more frequently because:
- Limestone sits close to the surface
- Groundwater movement is common
- Sandy soils shift easily
As long as erosion continues or the soil above remains unstable, the sinkhole can keep expanding.
When Does a Sinkhole Stop Growing?
A sinkhole typically stops growing when one of the following occurs:
- The underground void is fully collapsed and reaches a stable state
- Water movement slows or stops, reducing further erosion
- The soil compacts naturally over time
- Professional stabilization is completed
However, without proper repair, many sinkholes remain unstable—even if they appear to stop growing.
Are Sinkholes Dangerous to Your Home?
Not all sinkholes are catastrophic, but they should never be ignored.
Small sinkholes (often under 10 feet wide) can still:
- Cause foundation settlement
- Lead to cracks in walls or floors
- Create uneven or sinking areas around your home
In some cases, damage may worsen over time if the underlying issue isn’t addressed.
How Professionals Determine If a Sinkhole Is Stable
At Foundation Professionals of Florida, the first step is a detailed inspection.
This typically includes:
- Evaluating soil conditions
- Measuring foundation movement
- Identifying underground voids
- Determining whether the sinkhole is still active
This assessment helps determine whether the sinkhole has stopped growing—or if stabilization is still needed.
How Sinkholes Are Stabilized
If the sinkhole is still active or poses a risk, stabilization is essential.
One of the most effective methods is compaction grouting, which:
- Fills underground voids
- Strengthens weak soil
- Reduces future settlement
- Stabilizes your home’s foundation
This process not only addresses the current issue but helps prevent future damage.
Don’t Wait for a Sinkhole to Get Worse
Even if a sinkhole appears to have stopped growing, hidden instability can remain beneath the surface.
Getting a professional evaluation early can:
- Prevent costly repairs
- Protect your home’s structure
- Give you peace of mind

FAQs About Sinkholes
Do sinkholes stop growing?
Sometimes, but not always. Even if visible movement stops, underground instability may still exist.
How long do sinkholes last?
They can develop over years or decades depending on soil conditions and water activity.
Can a small sinkhole get bigger?
Yes. Small sinkholes can expand if the underlying void continues to grow.
Should I worry about a small sinkhole?
Yes. Even small sinkholes can lead to foundation damage if left untreated.
