Stop Your Driveway from Sinking
A sinking driveway can quickly become a safety problem around your home. Uneven slabs create trip hazards, cause water to collect near your garage, and make the entire entrance to your property look worn or neglected. Many homeowners believe the only solution is to tear out the driveway and pour new concrete, but that is often unnecessary and expensive.
Saint Louis Polyjack provides driveway leveling in St. Louis, MO using advanced polyurethane foam injection. Our process lifts and stabilizes sinking driveway slabs from underneath without the mess of demolition or cost of replacement. Most driveway repairs cost about 50% of full replacement, are completed in just a few hours, and the surface is typically ready to use the same day.
Why Driveways Sink
Driveways sit on top of soil, and when that soil changes, the concrete above it can begin to settle. Over time, natural ground movement and water erosion can create empty spaces beneath the slab.
Common causes of sinking driveways include:
- Soil erosion from rainwater or poor drainage
- Voids forming beneath the concrete
- Weak or poorly compacted soil during construction
- Seasonal expansion and contraction of soil
- Heavy vehicle weight over time
When these issues occur, the slab loses support underneath. Concrete leveling restores that support by filling the voids and lifting the slab back to its proper height.
Signs Your Driveway Needs Leveling
Driveway settlement usually happens slowly, which means many homeowners do not notice the problem until it becomes more obvious.
You may need driveway leveling if you notice:
- One slab sitting lower than the others
- A lip or edge forming between driveway sections
- Water pooling on the surface after rain
- Concrete tilting toward the garage or house
- Cracks forming as the slab moves
- A noticeable dip where vehicles drive
These issues can become worse over time if the void beneath the slab continues to grow.
Sometimes driveway settlement is connected to other concrete problems around the home. If you’re seeing uneven surfaces in multiple areas, our team also repairs garage floor leveling, walkway and sidewalk leveling, and patio leveling. In many cases, the same soil movement that causes a driveway to sink can also affect nearby concrete slabs.

Our Fix: Polyurethane Driveway Leveling
Saint Louis Polyjack uses a polyurethane foam injection process to lift and stabilize driveway slabs safely and efficiently. Instead of tearing out and replacing the concrete, our method restores support beneath the slab by filling hidden voids and strengthening the soil underneath.
Our process works in three simple steps:
1. Drill Small Access Holes
Small holes are drilled in specific areas of the slab to reach the empty space beneath the concrete.
2. Inject Expanding Polyurethane Foam
High-density foam is injected under the driveway. The material expands to fill voids, stabilize the soil, and gently lift the slab back into position.
3. Patch the Holes and Finish the Repair
Once the driveway is level, the drill holes are patched neatly. Most driveways are ready to drive on shortly after the repair is completed.
Benefits of Driveway Leveling
Concrete lifting offers several advantages compared to replacing a driveway.
Some of the main benefits include:
- Save up to 50% compared to full driveway replacement
- Fast repair that usually takes only a few hours
- Minimal disruption to landscaping and surrounding areas
- Long-lasting stabilization beneath the slab
- Improved drainage and reduced water pooling
- Elimination of trip hazards and uneven surfaces
Instead of removing the driveway, leveling restores the existing concrete while correcting the problem underneath.

FAQs – Driveway Leveling
Clear answers about cost, timing, appearance, and how lifting your
driveway actually works.
If your driveway has sections that are lower than others, creates a lip between slabs, or holds water after rain, it may be settling. Uneven surfaces and trip hazards are common signs that the concrete has lost support underneath.
In many cases, yes. If the concrete is structurally sound and not severely broken, polyurethane leveling can raise and stabilize the existing slab without tearing it out and pouring new concrete.
Most residential driveway leveling projects can be completed in just a few hours. The repair is fast and minimally disruptive compared to replacing the entire driveway.
Driveways are typically ready to drive on the same day after the repair is completed. The polyurethane foam cures quickly and provides strong support beneath the slab.
Small holes are drilled during the lifting process, but they are carefully patched once the slab is leveled. The repair is clean and far less noticeable than replacing the concrete.
Driveways usually sink because of soil erosion, poor soil compaction, or voids forming beneath the slab. Water movement and natural soil settling can cause the ground underneath the concrete to shift over time.
Yes. Polyurethane foam is designed to provide durable support beneath the slab by filling voids and stabilizing the soil. The repair is lightweight, strong, and backed by Saint Louis Polyjack’s 5-year warranty.
