Sunken Driveway Repair in Kansas City
Polyjacking & Polyurethane Concrete Lifting Solutions
Lift and level a sunken driveway without replacement. Polyurethane foam restores grade in hours — typical cost $1,000–$2,200.
Quick Answer
Sunken Driveway Repair, Plainly Explained
Sunken driveways in Kansas City are most often caused by soil settlement, erosion, or expansive clay soils. Polyjacking raises the existing concrete slab by injecting polyurethane foam beneath it, filling voids and restoring proper support — usually in a few hours.
A sunken or uneven driveway isn’t just appearance. It causes drainage issues, vehicle damage, and long-term structural stress.
Most driveway lifting projects in Kansas City run $1,000–$2,200, depending on slab size and settlement depth.
Lightweight Foam
Doesn't add stress to weak soils.
Precise Lift
Section-by-section grade restoration.
Same-Day Use
Drive on it within 15–30 minutes.
15–30 Min
Same-hour use after the lift.
1/10th Weight
Far lighter than cement slurry.
5/8" Ports
Small holes, patched flush.
Long-Term
Outlasts cement-based lifting in clay.
Why Driveways Sink in Kansas City
Common Causes We See Every Week
Expansive Clay Soil
Soil shrinks in dry summers, expands when wet. Voids form. Concrete drops.
Poor Original Compaction
Subdivision construction often rushes backfill. Settlement reveals it years later.
Water Runoff
Rain and snowmelt washing out subgrade beneath driveway edges and aprons.
Utility Trench Settlement
Sewer, gas, water lines installed years ago still consolidating beneath the slab.
Why Polyjacking Works for Driveways
Lighter Material, Better Precision, Less Downtime
Polyurethane concrete lifting adds minimal weight to weak soils, lifts slabs with precision, resists moisture and erosion, and cures quickly enough for same-day use.
Traditional mudjacking adds heavy cement slurry beneath driveways — which can increase stress on unstable soil. For this reason, polyjacking is usually the preferred solution in Kansas City.
Driveway Polyjacking Cost
What Most Kansas City Projects Run
Most driveway lifting projects in Kansas City range from $1,000–$2,200, depending on slab size, settlement depth, and access. Multi-section driveways with significant settlement run higher.
Either way, it’s a fraction of replacement cost ($4,000–$12,000+) and you keep the existing concrete.
When Driveway Replacement Isn't Necessary
Long-Term Stability for Sunken Concrete
If the slab is intact and structurally sound, lifting is almost always faster, less expensive, and less disruptive than replacement.
Replacement makes sense only if the concrete itself has failed structurally — severe fracturing, deterioration, or load-bearing damage. We’ll tell you straight at the inspection.
Sunken Driveway Repair FAQs

- Moisture-resistant support for long-term performance
What to Expect
Driveway Polyjacking, Step by Step
Free Inspection
An on-site evaluation that measures settlement, identifies the root cause, and confirms whether polyjacking is the right fix. About 20 minutes, no obligation.
Foam Injection
Closed-cell polyurethane injected through 5/8-inch ports under the slab. The foam expands, fills voids, and lifts concrete with millimeter precision.
Real-Time Lift
The slab raises as foam expands — visible in seconds, measured against benchmarks for accuracy. No guesswork, no slurry settling overnight.
Same-Day Use
Concrete is back in service within 15–30 minutes of injection. Walk on it, drive on it, no waiting for cure days.
Free Sunken Driveway Inspection
If a driveway is sinking, sloping toward the house, or creating drainage problems, an inspection takes about 20 minutes.
