Concrete Lifting in Kansas City
Modern Methods That Replace Sunken Slabs Without Tearing Them Out
Concrete lifting raises sunken or settled slabs back to grade. KC MudJack uses polyurethane concrete lifting — the modern method that replaced mudjacking in clay-soil regions like ours.
Quick Answer
What Concrete Lifting Means
“Concrete lifting” is the umbrella term for any method of raising sunken or settled slabs back to their original elevation. Two main methods exist: polyjacking (polyurethane foam — what we install) and mudjacking (cement slurry — the older method, largely replaced).
In Kansas City clay, polyurethane consistently outperforms cement slurry. That’s why we install polyurethane only.
Polyjacking
Polyurethane foam, modern method.
Mudjacking
Cement slurry, largely replaced.
Replacement
Last resort when slab has failed structurally.
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.
Concrete Lifting Applications
What We Lift Across the Metro
Driveways & Aprons
Most common application. Lifts ranging from a half-inch to several inches.
Sidewalks & Walkways
Panel-by-panel leveling for ADA compliance and trip hazard removal.
Garage Floors & Patios
Interior slab and outdoor leveling without demolition.
Pool Decks & Steps
Outdoor leveling that preserves drainage and finish.
How Concrete Lifting Works
Lighter Material, Better Precision, Less Downtime
Inspect the slab and identify settlement causes. Drill small ports. Inject lifting material (foam, in our case) beneath the slab. Material expands or fills voids, raising the slab. Patch the ports. Material cures into a stable support layer.
The difference between methods is what gets injected. That’s where polyurethane and cement-based mudjacking diverge.
Polyurethane Concrete Lifting (What We Do)
Modern Method, Engineered for Clay
Two-part polyurethane foam injected through small ports. Fills voids in the soil. Compacts loose subgrade. Lifts the slab with millimeter precision. Cures in 15–30 minutes.
Lighter than cement slurry, faster cure, more precise control, longer-lasting in Kansas City clay.
Lifting vs Replacement
Long-Term Stability for Sunken Concrete
For structurally sound slabs, lifting is faster (hours vs days), cheaper (often a quarter of replacement cost), less disruptive (no demolition), and visually consistent (preserves existing concrete).
Replacement only wins when the slab itself has failed structurally — severe fracturing, deterioration, or load-bearing damage.
Concrete Lifting FAQs
The most common questions about concrete lifting 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 Choose KC MudJack
What You Get From Our Crew
Polyurethane Only
We don’t install mudjacking, helical piers, or replacement. One method, done well — the modern polyurethane standard for residential lifting.
Local Expertise
Crews trained on Kansas City clay, freeze-thaw cycles, and Cass / Johnson / Jackson County soil conditions. Local knowledge, local accountability.
Free Inspections
Every quote starts with an on-site evaluation. No phone-only ballparks — clay settlement is too variable for accurate remote pricing.
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 Concrete Lifting Inspection
Whether you’ve been searching for “concrete lifting,” “polyjacking,” or “mudjacking,” the inspection is the fastest path to a real answer.

Concrete Lifting Resources
Polyjacking is one method of concrete lifting. Concrete lifting is the umbrella term — it covers polyjacking, mudjacking, and any other slab-raising approach.
$700–$3,000+ for polyurethane lifting. $600–$2,000 for cement-based mudjacking. $4,000–$12,000+ for replacement.
Polyurethane lifting provides long-term stabilization. Foam doesn’t shrink, wash out, or degrade in soil.
No — clay-soil settlement is too variable for accurate phone or online pricing. Final cost requires an on-site inspection.
Concrete lifting quick answer
What concrete lifting means in Kansas City
Concrete lifting raises settled slabs by filling empty space beneath the concrete and stabilizing the base. In Kansas City, polyurethane foam lifting is often used because it is lightweight, clean, fast curing, and well suited for many driveway, sidewalk, patio, and garage floor settlement problems.
Key facts
- Designed for settled slabs, not new concrete installation.
- Useful when the slab is mostly intact but unsupported.
- Kansas City clay, erosion, and freeze-thaw cycles can all contribute to settlement.
When it works
- Sunken concrete with voids beneath it.
- Trip hazards caused by settled panels.
- Garage floors, patios, sidewalks, and driveway panels that can still be preserved.
When it may not fit
- Heaved slabs pushed up by roots or structural movement.
- Badly deteriorated concrete surfaces.
- Slabs needing drainage correction before lifting.
