Uneven Driveway Lifted and Leveled in Des Peres, MO
The Problem
A homeowner in Des Peres, Missouri, had a concrete driveway that was no longer sitting evenly. Sections of the driveway had settled, creating noticeable changes in height between the slabs.
The uneven surface affected the driveway’s appearance and created rough transitions for vehicles and people walking across the concrete. Without proper support underneath, the affected slabs could continue to settle and move farther out of alignment.
Because the existing concrete remained in repairable condition, the homeowner wanted to lift and level the driveway rather than remove and replace it.
What We Found
When the STL Polyjack team inspected the driveway, we found:
- Settled driveway sections
- Uneven joints between concrete slabs
- Changes in elevation across the driveway
- Rough transitions between sections
- Reduced support beneath the concrete
- Voids beneath affected slabs
- Concrete that was still suitable for lifting
Polyurethane concrete lifting offered a practical way to restore support and improve the driveway’s alignment while preserving the existing slabs.
How We Fixed It
We used our polyurethane concrete lifting process to raise, level, and support the settled driveway sections.
Step 1: Drill Small Access Holes
Small access holes measuring approximately 5/8 inch were carefully drilled through selected areas of the driveway. These holes allowed us to reach the unsupported spaces beneath the settled slabs.
Step 2: Inject High-Density Polyurethane Foam
High-density polyurethane foam was injected beneath the affected concrete. As the foam expanded, it filled hidden voids, restored support, and gradually raised the settled driveway sections.
The lifting process was carefully controlled to improve the alignment between neighboring slabs and create a smoother driveway surface as closely as existing conditions allowed.
Step 3: Patch and Clean Up
After the driveway was lifted, leveled, and stabilized, the small injection holes were patched. The work area was then cleaned, leaving the existing driveway in place.
Because the polyurethane foam cures quickly, the homeowner was able to return the repaired driveway to normal use with minimal downtime.
The Results
The settled driveway sections were lifted and brought back into better alignment without removing and replacing the existing concrete.
The completed project provided:
- Settled driveway slabs lifted
- Improved alignment between sections
- Smoother transitions across the driveway
- Hidden voids filled beneath the concrete
- Support restored beneath affected areas
- A more even surface for walking
- Improved vehicle access
- Existing concrete preserved
- Minimal disruption around the property
- No full driveway replacement required
Existing slab, soil, and site conditions can affect the exact amount of lift possible. However, the affected concrete was adjusted to the best achievable position and stabilized from underneath.
Why Des Peres Homeowners Choose Polyurethane Concrete Lifting
A sinking driveway does not always need to be replaced. When the existing slabs remain repairable, polyurethane concrete lifting can address the missing support underneath while raising the concrete toward a better position.
The lightweight foam expands beneath the slab, fills hidden voids, and stabilizes the affected areas. Small access holes and fast curing also help keep the repair process clean and minimally disruptive.
