Trip Hazard Repair for Concrete Walkways
Fast, Code-Friendly Solutions in Kansas City
Eliminate concrete trip hazards with polyurethane concrete lifting. Faster and longer-lasting than grinding. Typical repair $700–$1,200.
Quick Answer
Trip Hazard Repair, Plainly Explained
Trip hazards form when concrete slabs settle unevenly. Polyurethane concrete lifting raises the lower slab using expanding foam, eliminating height differences and restoring safe access — often in under an hour.
Trip hazards are more than an inconvenience — they’re a safety and liability issue. KC MudJack specializes in trip hazard repair using polyurethane concrete lifting, restoring safe walking surfaces quickly and effectively.

ADA-Compliant
Eliminates the elevation change.
Soil Stabilization
Addresses the root cause beneath the slab.
15–30 Min
Same-hour use after the lift.

5/8" Ports
Small holes, patched flush.
Long-Term
Outlasts cement-based lifting in clay.
Where Trip Hazards Occur
Common Locations Across Kansas City
Sidewalks
Especially at panel joints where slabs settle differently.
Entryways
Front porches, business entries, walkup paths.
Patios
Between slabs and around door thresholds where settlement varies.
Commercial Walkways
Pool decks, parking lot transitions, retail entrances.
Why Grinding Is Often Temporary
Lighter Material, Better Precision, Less Downtime
Grinding removes concrete (weakens the slab), doesn’t fix underlying soil issues (cause is still there), can create drainage problems (alters surface profile), and doesn’t last (settlement continues).
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 or replacing slabs, without extended downtime, and without the disruption of demolition.
For property managers, HOAs, and commercial owners, it’s the cleanest way to address ADA risk and city code 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 right call: the slab is severely cracked or shattered, multiple slabs in a row have failed structurally, or the concrete itself is deteriorated below load-bearing strength.
In those cases, replacement is the right answer — and we’ll tell you straight at the inspection.
Trip Hazard Repair FAQs
The most common questions about trip hazard repair in Kansas City.
- Lightweight material that will not overload weak soils
- Fast cure times, often usable in 15 to 30 minutes
- High lift precision for cleaner leveling results
- Moisture-resistant support for long-term performance
Why Polyjacking Is the Right Fix
Four Reasons It Beats Grinding
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.
Long-Term Stability
Polyurethane doesn’t break down, wash away, or compress. Lifts hold for decades; mudjacking commonly re-settles within years in clay.

Typical Kansas City projects range from $700–$1,200, depending on slab size and height difference.
Sometimes upfront — but grinding is temporary. Polyjacking costs more initially but lasts much longer in clay subgrade.
Briefly during the lift itself. Most projects allow walkway return to use within an hour.
