Mudjacking Cost in Kansas City
Why the Cheaper Quote Sometimes Costs More
Mudjacking can look cheaper upfront. In Kansas City clay, it often costs more long-term once re-settlement is factored in.
Quick Answer
Mudjacking vs Polyjacking Cost in KC
Mudjacking typically runs $600–$2,000 in Kansas City. Polyjacking runs $700–$3,000+. That’s roughly 20–40% lower upfront for mudjacking.
But in Kansas City clay, mudjacking has a higher re-settlement rate. Factor in repeat repairs and polyjacking often costs less over a 5–10 year window.
Lower Upfront
Mudjacking usually 20–40% cheaper at quote stage.
Higher Long-Term
Re-settlement risk in clay drives total cost up.
Replacement Avoided
Either method beats $4,000–$12,000+ replacement.
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.

What's Not in the Quote
Lighter Material, Better Precision, Less Downtime
Mudjacking’s lower upfront price comes with conditions: slower cure (hours to days of downtime), higher re-settlement risk in clay, larger injection holes (1.5″–2″), and heavier material that adds load to soil already under stress.
If a mudjacked slab re-settles within 3–5 years and needs another lift, you’ve paid twice — and the second lift is often a polyurethane job anyway.
The Long-Term Math
A Realistic 5–10 Year Cost Comparison
Suppose a mudjacked driveway lift is $1,400 in Kansas City clay and lasts 5 years before re-settling. You then pay another $1,400 — or more likely $1,800 for the polyurethane fix that finally holds.
Mudjacking total over 5–10 years: $1,400 + $1,800 = $3,200. Polyjacking total: $1,800 once. The cheaper quote upfront ends up being the more expensive choice.
When Mudjacking Cost Actually Wins
Some Cheap Repairs Cost More Later
Short-hold property (you’re selling within a year or two). Stable, non-clay soil conditions. A purely budget-driven decision with re-settlement risk acknowledged.
For most Kansas City homeowners staying in their property, the polyjacking math wins on a multi-year horizon.
Mudjacking Cost FAQs
The most common cost-comparison questions from Kansas City homeowners.
- 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
What Affects Cost
Variables That Determine the Final Number
Slab Size
Square footage and lift volume drive labor and material cost. Single-panel sidewalks are lowest; multi-slab driveways scale up.
Settlement Depth
Deeper settlement requires more foam and longer pump time. Most residential jobs need ½ inch to 2 inches of lift; severe drops cost more.
Soil Conditions
Clay, voids, washouts, or under-compacted fill all affect price. Heavier soil stabilization adds material; standard sites are quick and predictable.
Project Scope
Single slab vs combined projects (driveway + walkway + porch) shift per-job cost. Bundled lifts often save money over separate visits.

Cost Resources
Cement slurry is a less expensive material than polyurethane foam, and mudjacking equipment is older and more widely available. Lower input costs translate to lower upfront pricing.
It can — particularly in expansive clay soils like Kansas City’s. Re-settlement isn’t guaranteed, but the rate is meaningfully higher than with polyurethane.
Mudjacking might be the right call. We don’t offer it, but a few KC contractors still do. We’re not the right contractor for that job.
Rarely upfront. But the total cost of ownership over 5–10 years is often lower with polyurethane.
