Driveway Approach Sinking & Concrete Lifting in Dunwoody, GA
Case Study: Driveway Approach Lifting in Dunwoody
A sinking driveway approach can create an uncomfortable bump where the driveway meets the street. It may also cause water to collect, make vehicle access more difficult, and place additional stress on the surrounding concrete.
That was the issue this homeowner in Dunwoody, GA was experiencing. The concrete near the entrance of the driveway had settled, leaving an uneven transition between the driveway and roadway.
The Problem
The driveway approach had gradually sunk as the supporting soil beneath the concrete weakened and shifted. The low section created a noticeable dip that affected both the appearance and everyday use of the driveway.
The homeowner was concerned about:
- A rough transition from the street
- Vehicles scraping near the driveway entrance
- Water collecting in the settled area
- Gaps developing beneath the concrete
- Continued sinking and cracking
The concrete itself was still in usable condition, so removing and replacing the entire approach would have been unnecessary and expensive.
The Solution: Polyurethane Concrete Lifting
After inspecting the affected area, Poly Lift USA recommended lifting and stabilizing the driveway approach with high-density polyurethane foam.
The foam was injected beneath the settled slab to fill hidden voids, restore support, and carefully raise the concrete closer to its proper position.
This repair helped the homeowner:
- Create a smoother driveway entrance
- Reduce the uneven drop near the road
- Fill unsupported areas beneath the slab
- Improve drainage around the driveway
- Avoid costly concrete replacement
The Process
Our crew completed the driveway approach repair using three simple steps.

1. Precision Drilling
Small access holes were drilled through the settled section of the driveway approach at carefully selected injection points.
2. Controlled Foam Injection
High-density polyurethane foam was injected beneath the concrete. As the material expanded, it filled hidden voids and gently lifted the slab while adding support underneath.
3. Patch & Clean Up
Once the driveway approach reached the desired position, the access holes were patched and the work area was cleaned.
The process required minimal disruption and allowed the existing concrete to remain in place.
The Results
The driveway approach was lifted and stabilized in just a few hours.
The homeowner now has:
- A smoother transition from the road
- Better support beneath the concrete
- Improved water drainage
- Reduced risk of continued settlement
- A driveway ready for same-day use
The project restored the function and appearance of the driveway entrance without the time, mess, and expense of full replacement.
Why Dunwoody Homeowners Choose Concrete Lifting
Driveway approaches can settle because of soil movement, poor compaction, erosion, and repeated vehicle traffic. When the slab is still structurally sound, polyurethane concrete lifting can provide a faster and more affordable repair option.
Benefits include:
- No major demolition
- Small injection holes
- Minimal property disruption
- Fast project completion
- Same-day use in most cases
- Savings compared to replacement
By filling the empty spaces beneath the concrete, lifting can restore support and extend the useful life of the existing driveway.
