Found a Hole or Sunken Spot? Don’t Fill It In, Call Us First.
Middle Tennessee sits on some of the most active karst limestone in the country. Sinkholes can appear in yards, driveways, and near foundations throughout Franklin, Brentwood, Nashville, and surrounding communities. Before any repair can begin, the area must be excavated, inspected, and cleared to identify what’s causing the collapse. Our sinkhole clean-out service provides the critical first step toward a permanent solution.
What Is a Sinkhole Clean-Out?
A sinkhole clean-out is the excavation and inspection phase of the repair process. Before a sinkhole can be repaired, the affected area must be opened up so the underlying cause can be identified and removed.
Common causes include:
- Natural limestone voids created by karst geology
- Buried construction debris, tree stumps, and organic materials
- Soil erosion beneath the surface
- Underground deterioration from decades-old fill materials
Without excavation, there’s no reliable way to determine the size, depth, or cause of the problem.
Signs You Need Sinkhole Clean-Out Services
Watch for these warning signs:
- Sinking or soft areas in your yard
- Depressions forming near driveways
- Cracks in foundations, sidewalks, or slabs
- Water pooling in areas that previously drained properly
- Recurring settlement after adding fill dirt
- Holes that continue growing after rainstorms
If you notice any of these conditions, professional evaluation is recommended before the issue worsens.
Why Sinkholes Are Common in Middle Tennessee
The geology beneath Franklin, Nashville, Brentwood, and much of Middle Tennessee consists of limestone karst formations. As limestone dissolves over time, underground voids can develop, eventually causing the soil above to collapse.
In addition to natural sinkholes, many properties contain buried construction debris from previous development. As these materials decompose, the ground loses support and settlement occurs.
Because sinkholes are a recognized regional concern, every clean-out should be approached as a professional excavation project rather than a simple surface repair.
Our Sinkhole Clean-Out Process
1. On-Site Assessment
We inspect the affected area and evaluate the likely cause of the settlement.
2. Excavation
The depression is carefully opened using equipment appropriate for the location and depth.
3. Debris Identification & Removal
Organic materials, construction debris, and unstable soils are removed from the cavity.
4. Photo Documentation
We document findings throughout the excavation process for property records and insurance purposes.
5. Engineer Coordination (If Needed)
For larger voids or sinkholes near structures, we can coordinate third-party engineering evaluations.
6. Preparation for Repair
Once the area is cleared and assessed, it is ready for structural fill and permanent repair.
Don’t Make the Mistake of Filling It Yourself
Many homeowners attempt to solve the problem by adding topsoil or fill dirt. Unfortunately, this often makes the issue worse.
Adding material without identifying the source of the collapse places additional weight on unstable ground. The void remains beneath the surface and continued settlement is almost guaranteed.
The only reliable solution is to excavate, identify the cause, remove unstable materials, and then proceed with proper repair methods.
What Happens After the Clean-Out?
Once excavation is complete and the source of the problem has been identified, we move into the repair phase. Structural fill, compaction, and site restoration are used to stabilize the area and prevent future settlement.
Most projects are completed as a continuous process:
Assessment → Excavation → Clean-Out → Structural Fill → Compaction → Restoration

Frequently Asked Questions
How do I know if it’s a sinkhole or a drainage problem?
A drainage issue typically involves standing water that eventually disappears. A sinkhole often continues growing, settling, or develops alongside cracking and ground movement.
How deep are sinkholes usually?
Depth varies significantly depending on the cause. Some are only a few feet deep while others extend much farther underground.
Will homeowner’s insurance cover sinkhole work?
Coverage depends on your policy. We provide excavation documentation that may assist with insurance claims.
Do I need an engineer?
Not always. However, if the sinkhole is near a home, garage, pool, or other structure, engineering review is often recommended.
