Driveway Lifting, Stabilization & Crack Repair in Seymour, TN
Case Study: Settled Driveway Repair in Seymour
A sinking driveway does not always mean the concrete needs to be replaced. In many cases, the slab itself is still in usable condition, but changes in the soil underneath have caused sections of the driveway to lose support and settle.
That was the issue for this homeowner in Seymour, TN.
Part of the driveway had settled and needed to be lifted and stabilized. There was also a crack in the concrete that needed to be caulked after the lifting work was completed.
The goal was straightforward: lift the settled driveway, restore support underneath, stabilize the concrete, and seal the crack to help protect the repaired area.
The Problem
As the driveway settled, sections of the concrete were no longer sitting at their original elevation.
Settlement like this often develops when the soil or supporting material underneath the driveway changes. Voids can form beneath the slab, leaving portions of the heavy concrete without consistent support.
The homeowner was dealing with:
- A settled driveway section
- Uneven concrete surfaces
- Lost support beneath the slab
- A crack in the driveway
- Concern about continued movement
- An uneven overall appearance
Because the existing driveway was a candidate for lifting, removing and replacing the settled concrete was not necessary.
The Solution: Lift & Stabilize the Existing Driveway
After evaluating the driveway, Poly Lift USA recommended polyurethane concrete lifting and stabilization.
High-density polyurethane foam was injected beneath the affected concrete to fill unsupported areas and carefully raise the settled slab.
Rather than adding another heavy material beneath already unstable concrete, polyurethane foam provides lightweight support while expanding into hidden spaces underneath the slab.
The repair helped:
- Lift the settled driveway
- Restore support beneath the concrete
- Fill hidden voids
- Improve alignment between concrete sections
- Stabilize the affected area
- Preserve the existing driveway
Once the lifting was completed, the driveway crack was caulked as part of the repair.
The Process
Our crew completed the driveway repair using a controlled lifting and stabilization process.

1. Inspect the Settled Concrete
The driveway was evaluated to identify the sections that had dropped and determine where additional support was needed underneath.
Small access holes were then drilled at carefully selected injection points.
2. Lift & Stabilize
High-density polyurethane foam was injected beneath the settled driveway.
As the foam expanded, it moved into voids beneath the slab and restored support to the affected areas. The concrete was carefully lifted to improve its position and alignment with the surrounding driveway.
3. Caulk the Crack & Finish
After the driveway was lifted and stabilized, the crack was caulked to seal the opening.
The injection holes were also patched, and the work area was cleaned before the project was completed.
The Results
The driveway was lifted and stabilized without tearing out the existing concrete.
The completed repair provided:
- A more level driveway surface
- Improved support beneath the slab
- Filled voids beneath problem areas
- Better alignment between concrete sections
- A sealed driveway crack
- Reduced uneven areas
- Existing concrete preserved
Instead of replacing the affected section, the homeowner was able to address the underlying settlement while keeping the driveway already in place.
Why Lifting Was the Right Choice
When a driveway sinks, the visible problem is above ground, but the cause is often underneath the concrete.
Simply patching a crack or filling an uneven joint does not restore missing support beneath a settled slab.
Polyurethane concrete lifting addresses the problem below the surface by filling voids and supporting the existing concrete while carefully raising it.
For this Seymour driveway, lifting and stabilization helped the homeowner avoid unnecessary demolition while improving the condition of the existing concrete.
Benefits include:
- Minimal disruption
- Small injection holes
- Controlled concrete lifting
- Void filling beneath the slab
- Existing concrete stays in place
- Faster than traditional replacement
