Tennessee limestone has a few holes in it.
Voids, soft spots and sinkholes in limestone country are investigated and stabilized with grouting, caps and piers, so homes are supported on firm ground.
- First step: Safety and investigation
- Methods: Grouting, caps, piers, drainage
- Experts: Engineers and geologists as needed
What it is, and why it matters.
Tennessee sits on limestone that dissolves over time, leaving voids, caves and sinkholes. Most are stable for generations, but water changes things: a broken pipe, a missing gutter or a heavy storm can wash soil into a void and drop the ground.
We investigate with probing and, where needed, specialists, then stabilize with compaction grouting, cap or plug methods, piers to rock and drainage fixes. A depression in the ground should never just be filled with dirt.
Four things done right.
Safety first
We mark off the area and keep people clear.
Investigated properly
Probing finds the extent of the void.
Right stabilization
Methods matched to the feature.
Water redirected
Drainage stops the washing-out.
From first call to sinkhole and karst stabilization.
- 01
Secure the area

- 02
Investigate
Probing and specialists define the void.
- 03
Stabilize
Grouting, caps or piers are installed.
- 04
Restore
The ground is repaired and drainage fixed.

Sinkhole and Karst Stabilization: common questions
What should I do if a sinkhole opens in my yard?
Keep people, pets and vehicles away, turn off any suspected leaking water, divert runoff and call for an inspection. Do not fill it with random material.
Is my house in a sinkhole area?
Large parts of Middle and East Tennessee sit on karst limestone. A site evaluation can tell you more about your lot.
