Uneven Sidewalk & Trip Hazard Repair
Concrete Leveling That Restores Safe, ADA-Compliant Walkways
Polyjacking eliminates uneven sidewalks and trip hazards in Kansas City. ADA-compliant lifts, no demolition, typical cost $700–$1,000 per panel.
Quick Answer
Sidewalk Leveling, Plainly Explained
Uneven sidewalks form when concrete slabs settle at different rates. Polyjacking lifts settled panels using expanding polyurethane foam, eliminating trip hazards and restoring smooth, ADA-compliant walking surfaces — usually in under an hour per panel.
Trip hazards aren’t just inconvenient. They’re a safety risk and, for property managers, a liability and ADA compliance issue.
Precise Lift
Match the height of adjacent panels exactly.
ADA-Compliant
Eliminates the elevation differential cleanly.
No Grinding
Addresses the soil cause, not just the surface.
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 Sidewalks Settle
Common Causes We See
Soil Erosion
Water cutting beneath panels over time, washing out subgrade.
Tree Root Displacement
Roots pushing soil against or beneath sidewalk panels.
Poor Compaction
Original install backfill that never fully consolidated.
Aging Trenches
Utility trenches installed years ago still settling beneath the surface.
Why Polyjacking Beats Grinding
A lighter, more precise repair option for settled sidewalks
Grinding looks fast and cheap. It’s also a band-aid: removes concrete (weakens the slab over time), doesn’t fix underlying soil issues, can create drainage problems, and doesn’t last.
Polyjacking stabilizes the soil beneath the slab, preventing future movement. It’s a fix, not a workaround.
Reduce Liability Without Replacement
What Polyjacking Eliminates
Polyjacking eliminates trip hazards without cutting or grinding the concrete, without removing slabs, without extended downtime, and without disruption to landscaping or adjacent slabs.
For HOAs, property managers, and commercial property owners, it’s the cleanest way to address slip-and-fall liability and ADA compliance without taking the walkway out of service for days.
When Replacement Is Right
Long-Term Stability for Sunken Concrete
A few situations where lifting isn’t the answer: the panel is severely cracked or shattered, multiple adjacent panels have failed structurally, or the concrete itself is deteriorated below load-bearing strength.
For most settlement-driven sidewalk issues, lifting is the right fix.

Why Polyjacking Is Ideal for Sidewalks
Six Reasons It's the Right Method
Precise Leveling
Foam injection brings panels back to within a fraction of an inch — accurate enough to meet ADA compliance and pedestrian-safety standards.
Minimal Disruption
Small access ports, no jackhammering, no slurry runoff. Sidewalks stay open during work and ready for foot traffic almost immediately.
ADA-Compliant Result
Lifted panels meet ADA tolerance for vertical changes in level — under 1/4 inch — without re-pouring, grinding, or replacing the slab.
Walkway Stays Open
Pedestrian access is restored within minutes of foam injection. Most sidewalk lifts complete during a normal business day with no closures.

Most panels are lifted in under an hour. Foam reaches load-bearing strength within 15–30 minutes.
Yes. The lifted panel is the same panel — just back at the right elevation.
Rarely. Grinding is a temporary fix that doesn’t address the underlying soil. Polyjacking lasts longer.
