Cracks in drywall, especially at top corners of window & door openings. Cracked or out-of-level floors, slabs, sidewalks or driveways.
How do sinkholes form?
Solution sinkholes occur when rainwater erodes the limestone under a thin layer of soil, causing shallow sinkholes to gradually form on the surface. Subsidence sinkholes occur when the soil layer over the limestone bedrock is mainly comprised of sand. The water erodes the limestone, creating voids. The sand then filters down into these voids ...

What is the scariest type of sinkhole?
Cover-collapse sinkholes -- the scariest type of sinkhole -- occur where the soil layer is deeper over the sinkhole and more cohesive than sand. This soil, which is more consolidated because of clay and root content, can bridge voids that form in the underlying limestone, effectively hiding a subterranean cavern.

Do sinkholes destroy structures?
Not only does sinkhole activity destroy structures, but they also pose an environmental concern.

What are sinkholes in Florida?
In Florida you might see solution sinkholes, cover-subsidence sinkholes or cover-collapse sinkholes. The first of these three, solution sinkholes , usually occur where there is little or no sediment cover over the limestone. The rock is readily dissolved away at or near the ground surface or along joints or other openings. Cover-subsidence sinkholes are located where thick permeable sediments cover the limestone. In this case, the void in the rock is filled by sediments raveling downward from above. Eventually, the ground surface often shows a gentle circular depression. If a relatively thick layer of impermeable sediments covers the limestone, there may not be a surface expression of a subsurface collapse. Cover-collapse sinkholes occur where sediments overlying the void in the rock suddenly collapse, creating a hole at ground surface.
How to fill a sinkhole with earth?
Since anything buried in the earth potentially affects the groundwater, use only native earth materials or concrete for the fill. Broken limestone rip-rap or a concrete plug in the bottom of the sinkhole often helps create a stable foundation for the fill. Above that, add clayey sand to form a barrier that will help prevent water from seeping downward through the hole and enlarging it further. Lastly, add sand and top soil, and landscape to surrounding conditions. Additional fill may be necessary over time as the filled material settles and compresses with time.
What is the number to call for sinkholes?
Should you have additional questions, you may call the FGS Sinkhole Helpline at 850 245-2118. NOTE:, this is a helpline provided to: Clarify the information presented in the FAQs below.
How do sinkholes form in karst?
Sinkholes form in karst terrain principally from the collapse of surface sediments into underground voids and cavities in the limestone bedrock. Slightly acidic groundwater slowly dissolves cavities and caves in the limestone over a period of many years.
How long does it take for a sinkhole to collapse?
The initial hole that forms may continue to grow over a period of minutes to hours to days depending upon the size and scale of the sinkhole. Slumping of the sediments along the sides of the sinkhole may take approximately a day’s time to stop. Erosion of the edge of the sinkhole may continue for several days, and heavy rainfall can prolong the stabilization. In the less catastrophic cover-subsidence type of sinkhole, sediments slowly ravel into underground voids in the bedrock. A bowl-shaped depression forms at the surface, typically over longer periods of time (sometimes as long as years and much longer).
What is a sinkhole?
Sinkholes are closed depressions in areas underlain by soluble rock such as limestone and dolostone, or, as in some states, gypsum and salt. Sinkholes form when surface sediments subside into underground voids created by the dissolving action of groundwater in the underlying bedrock.
What to do if you see a sinkhole?
Warning signs include : Slumping of the ground. Leaning trees or fence poles.
How does a sinkhole form?
This kind of sinkhole forms slowly. Dissolution or solution sinkholes happen when there is not very much soil or vegetation covering the limestone or bedrock. Water slowly flows over the bedrock and dissolves it. This results in a depression that might become a pond if it gets lined with debris. Surface water then fills the crevices in the limestone and slowly dissolves it, forming a sinkhole
What is grouting in sinks?
This type of grouting is also known as polyurethane grouting. It involves injecting a resin (usually polyurethane) into a sinkhole in order to fill the void. The polyurethane resin expands into an inert foam, and lifts and stabilizes the slab or floor. The amount of pressure and expansion depend on the type of chemical compound used.
What is grouting in Florida?
Grouting involves injecting grout into the soil in order to stabilize it. It stops the soil from shifting or moving, and fills voids created by sinkhole activity. At Foundation Professionals of Florida, we use both cement and chemical (polyurethane) grouting.
What are the signs of a septic system?

Can sinkholes collapse?
These sinkholes collapse quickly and can be very dangerous. With this kind of sinkhole, there is usually a layer of clay under the ground cover and above the bedrock. Sediment s from the ground level erode over time, and when only a thin layer remains, a sinkhole can open up quickly, revealing the under ground void that has been forming.
Where are sinkholes most likely to occur in Florida?
Currently, the areas with the highest risks for sinkholes are along the coasts of Florida, especially in regions where limestone is close to or at the surface. These include Hernando, Pasco, Hillsborough, and Pinellas counties.
What are Sinkholes?
Sinkholes are natural disasters that can devastate your property and ruin your day. In the past decade, sinkhole coverage has become more popular as sinkhole events have increased in frequency. Sinkholes happen when water from rain, snowmelt, or irrigation wears away rocks under the land until it eventually collapses. The ground either sinks or heaves up, creating what is known as a sinkhole.
Why sinkhole insurance is important?
The most dangerous sinkholes are those that occur without any warning. When sinkhole insurance is not purchased, there’s no guarantee that the damage will be covered as sinkholes can happen at any time without warning.
What is the most common type of sinkhole?
The most common type of sinkhole is called an edge collapse sinkhole which occurs when the groundwater corrodes rocks along the edges of streams and rivers causing them to break away into the streambed below, forming deep vertical shafts that lead to underground caves. When these cave openings get too big for their ceilings, they will collapse causing sinkholes on the surface.
What happens if you get a sinkhole in your home?
That means that if your home suffers from a sinkhole, you will be able to get help with repair costs through your insurance company.
Why is Florida known as the sinkhole capital of the country?
The state is also known as the “sinkhole capital of the country”. This is due to the fact that Florida is lying on top of a bedrock of carbonate, primarily limestone. That rock dissolves relatively easily in rainwater, which becomes acidic as it seeps through the soil. The resulting terrain, called “karst” is honeycombed with cavities. When a cavity becomes too big to support its ceiling, it suddenly gives way, collapsing the clay and sand above to leave a cavernous hole at the surface.
What is sinkhole insurance?
One benefit of this insurance is that it covers the loss of your building contents as well as any structural damages incurred from a sinkhole. It pays for the costs associated with fixing any foundation damage caused by a sinkhole. The coverage also includes any damages to outside buildings, porches and driveways.
