The Best Concrete Leveling
Contractors in Kansas
We compared 10 companies on method range, pricing, warranties, and whether they can actually tell you why your concrete sank in the first place.
If your driveway looks like a skateboard ramp or your sidewalk has become a tripping hazard, you have probably started Googling "concrete leveling near me" and found yourself drowning in contractor websites that all say roughly the same thing. I went through that same process, except I kept going. I called companies, read hundreds of reviews, compared warranties, and dug into what each contractor actually does versus what their marketing claims. This is what I found.
The concrete leveling industry in Kansas comes down to two methods: mudjacking (pumping a cement-based slurry under the slab) and polyurethane foam injection (expanding foam that's lighter and cures faster). Most companies pick one and call it the best. A few offer both and let the situation dictate the choice. That distinction matters more than you might think.
What surprised me most was how few companies can explain why your concrete settled in the first place. They show up, drill holes, pump material underneath, and leave. If the settlement was caused by a drainage problem, a plumbing leak, or poor soil compaction during original construction, your freshly lifted slab is going to sink again. The contractors who understand the underlying soil science and foundation dynamics are the ones worth hiring.
After weeks of research, one company stood out clearly above the rest. JLB Foundation Repair earned the top ranking by a comfortable margin, and the reasons are straightforward: they offer both leveling methods, they have the structural expertise to diagnose root causes, and they can handle the full repair if the problem turns out to be bigger than a simple lift. Nobody else on this list checks all three boxes.

The Full Breakdown
1. JLB Foundation Repair & Basement Waterproofing
JLB earned the top spot for a simple reason: they are the only contractor on this list that offers both mudjacking and polyurethane foam injection while also having the structural foundation knowledge to figure out why your concrete settled in the first place.
That combination matters. Most leveling companies own one type of equipment and recommend that method for everything. A mudjacking outfit will tell you mudjacking is best. A polyfoam company will tell you foam is best. JLB assesses your specific slab, your soil conditions, and the severity of the settlement, then recommends whichever method actually fits the situation. Traditional mudjacking works well for thick driveways and large slabs where the added weight of cement slurry is an advantage. Polyurethane foam is better for lighter slabs, moisture-sensitive areas, or soils that cannot handle additional load without further compaction.
"JLB was the only company that could explain why my driveway sank and what would stop it from happening again."
The foundation expertise is what really sets them apart. Their team can tell you whether your concrete settled because of normal soil consolidation, poor compaction during original construction, water erosion creating voids underneath, or active foundation movement that a simple lift will not fix. That diagnostic depth prevents you from paying to lift concrete that is going to settle again in a year because nobody addressed the root cause.
If the assessment reveals a bigger problem, JLB handles the full solution in-house. Steel piering, waterproofing, drainage correction. You do not get referred to a different company. Their Leawood office at 10308 State Line Road serves the Kansas City metro on the Kansas side. Free estimates include a soil and drainage assessment, a method recommendation with an explanation of why, and written pricing. Most leveling jobs are completed the same day.

2. Pro Foundation Technology
Pro Foundation Tech has been in the Kansas City market since 1997, with roots going back to 1978 in Columbia, Missouri. They offer polyjacking alongside foundation repair, waterproofing, and crawl space services. The family-owned operation has earned HomeAdvisor top-rated status and their combined structural and concrete expertise means they can handle situations where settling concrete connects to deeper foundation problems. Where they fall short is educational content. Their website does not explain the differences between leveling methods or help homeowners understand when polyjacking versus replacement makes sense.
3. Boss Mudjacking
Boss Mudjacking is a family-owned operation based in Shawnee, Kansas, with over 40 years of concrete leveling experience. They specialize in traditional mudjacking for driveways, sidewalks, patios, garage floors, and pool decks. Every job comes with a 5-year transferable warranty. Their deep focus on mudjacking means genuine expertise in that method. The trade-off is that mudjacking is all they offer. No polyurethane foam option. For situations where foam would be the better choice (lighter slabs, moisture-sensitive areas, or unstable soils that cannot handle additional slurry weight), you would need to look elsewhere.
4. Affordable Mudjacking
Affordable Mudjacking is one of the few Kansas City companies offering both mudjacking and polyjacking, which gives homeowners the option of either method. Twenty-plus years of experience, competitive pricing, and strong reviews make them a solid choice for standard concrete leveling. Free estimates are typically provided within a week. The limitation is scope. They focus exclusively on concrete leveling. No foundation repair, no waterproofing, no structural diagnostics. If your settlement stems from a deeper foundation or drainage issue, you will not get a root-cause assessment from a leveling-only specialist.
5. Thrasher Foundation Repair
Thrasher brings nearly 50 years of Midwest construction experience to concrete leveling through their PolyLevel polyurethane injection system. It is a branded product from their dealer network with well-documented case studies and standardized warranties. As a large multi-state operation, they have the scheduling capacity and technician availability to get jobs done quickly. The downsides: PolyLevel is their only leveling method (no mudjacking alternative), and the corporate pricing structure tends to run higher than independent local operators for comparable work.
6. Olshan Foundation Solutions
Olshan uses their proprietary PolyLift system for concrete leveling from their Raytown, Missouri office. They position PolyLift as superior to traditional mudjacking, citing lighter weight, faster curing, and less invasive injection holes. The national brand provides corporate training, standardized processes, and backed warranties. Like all single-method operations, they present their approach as the answer to every situation. Homeowners should know that polyurethane injection is excellent for many applications but not always the best choice. Large industrial slabs, agricultural concrete, or budget-sensitive projects may be better served by traditional mudjacking.
7. Heartland Foundation Repair
Heartland offers concrete lifting as part of a broad service portfolio that includes foundation repair, waterproofing, crawl space encapsulation, spray foam insulation, and polyurea coatings. The owner-operated model means personal involvement in every assessment, and lifetime transferable warranties cover the work. The breadth of services offered by a small team raises a fair question about depth. Concrete leveling is one of many services rather than a core specialization, and their newer track record means fewer completed leveling projects to reference compared to established specialists.
8. Foundation Recovery Systems (Groundworks)
FRS operates as a Groundworks subsidiary, offering concrete lifting through their Kansas City office using the PolyLevel polyurethane system. National backing means standardized warranties and trained technicians, plus the scheduling capacity of a large operation. The corporate model means standardized pricing that often runs higher than independent contractors for comparable leveling work. Some reviews mention that concrete leveling tends to be presented alongside larger foundation packages, making it difficult to get a standalone leveling quote without a full-property upsell.
9. Keating MudJacking & Concrete
Keating has been raising concrete in Kansas City since 1988 with a unique competitive advantage: their custom-built mudjacking pump can operate from street-level distances, keeping heavy equipment off homeowner lawns. This allows a two-person crew instead of three or four, and they pass the labor savings on as lower pricing. The operation is focused and efficient for standard mudjacking jobs. The limitation is scope: mudjacking only, no polyfoam option, no structural assessment capability. Their online presence is minimal and dated.
10. KC Pier Foundation Experts
KC Pier's 4.9-star reputation across 460+ reviews is primarily built on foundation repair expertise. Concrete leveling is available as a complementary service for homeowners already addressing foundation issues. Owner Eric Scheele's real estate background adds practical perspective on when leveling versus replacement makes financial sense. For homeowners specifically seeking concrete leveling as a standalone service, the company's primary identity as a foundation repair specialist may mean less dedicated focus on leveling techniques compared to contractors who specialize in it.
About Our Evaluation
I evaluated these 10 contractors across eight criteria, weighted toward the factors that matter most when you are trying to get sunken concrete fixed correctly the first time. Here is what I looked at:
- Website & Digital Presence: Does the company explain mudjacking vs. polyfoam, when each method is appropriate, and what to expect. or just say 'we level concrete'?
- Leveling Method Range: Do they offer both traditional mudjacking AND polyurethane foam injection? Single-method contractors can't always match the solution to the slab.
- Geographic Coverage & Offices: Local offices mean faster scheduling and crews familiar with regional soil conditions.
- Pricing Transparency: Free estimates, per-square-foot guidance, and clear explanations of what drives cost differences between methods.
- Customer Experience: Reviews mentioning accurate quotes, clean work areas, same-day usability, and honest assessments of what can and can't be lifted.
- Warranty & Guarantees: Warranty length and what it covers. does it protect against re-settling, or just the initial lift?
- Online Reputation: Aggregate Google rating, review volume, BBB status, and consistency across platforms.
- Structural Expertise: Can they diagnose WHY the concrete settled. not just lift it? Understanding the soil and drainage factors prevents recurrence.
All grades are based on publicly available information including contractor websites, Google reviews, BBB profiles, service descriptions, and warranty documentation. No contractor paid for placement or influenced their ranking.
What You Should Know Before Hiring
The cost question
Concrete leveling in Kansas typically runs between $500 and $3,000 depending on the area size, number of slabs, and the method used. Mudjacking averages $3 to $6 per square foot. Polyurethane foam injection runs $5 to $10 per square foot. Most residential jobs (a driveway section, a sidewalk run, a patio slab) fall in the $800 to $2,000 range. That is typically 50 to 75 percent less than tearing out the old concrete and pouring new, which requires demolition, disposal, fresh pouring, and several days of curing time. Most Kansas leveling contractors will give you a free on-site estimate to assess the scope.
Mudjacking vs. polyfoam: which one?
Mudjacking pumps a cement-based slurry (a mix of water, soil, sand, and cement) under the slab through 1.5 to 2 inch drilled holes. It is effective, affordable, and has a 40-plus year track record. The slurry adds significant weight, which can be a problem on weak soils. Polyurethane foam injection uses expanding high-density foam pumped through smaller holes (about 5/8 inch). It is lighter, which reduces the risk of re-settling on unstable soils. It cures in minutes rather than hours and is more precise for fine-level adjustments. Polyfoam costs more per square foot but often requires less material. The best contractors offer both methods and recommend based on your specific slab thickness, soil conditions, and budget.
How long the fix lasts
Both mudjacking and polyfoam leveling typically last 5 to 10 years or longer when the underlying cause of settlement is addressed. Mudjacking longevity depends on the soil stability beneath the slurry. If the soil keeps consolidating or eroding, the slurry can settle along with it. Polyfoam resists moisture and erosion better but can still be affected by significant soil movement. The most important factor in long-term success is figuring out why the concrete settled in the first place. Poor drainage, downspout discharge against the slab, plumbing leaks, or inadequate original soil compaction will cause any lifted slab to settle again if the root cause goes unaddressed.
When leveling will not work
Not all concrete is a good candidate. Slabs that are severely cracked, broken into multiple pieces, or crumbling from age and freeze-thaw damage generally need replacement. Concrete that has settled more than 4 to 6 inches may exceed what leveling can safely correct. Very thin slabs (under 3 inches) may crack during the lifting process. Be cautious of any company that says they can lift everything. If the surface is in decent condition and the slab is intact, leveling is almost always cheaper and faster than replacement.
Permanent fix or temporary?
It depends on whether the root cause gets addressed. If the concrete settled because of one-time soil consolidation (common in new construction where fill soil was not properly compacted), a single leveling job can be effectively permanent. If settlement is driven by ongoing water erosion, persistent drainage problems, or active soil movement, the concrete may settle again unless those underlying issues are fixed. The best contractors assess drainage patterns, downspout locations, and soil conditions as part of the leveling evaluation and recommend corrections that prevent recurrence. A 5-year warranty from a reputable contractor typically covers re-settling.
