In Manhattan, KS, spring snowmelt and heavy rains cause the city’s clay soil to expand, followed by hot, dry summers that make the soil shrink and crack. Concrete surfaces often follow suit, leading to sinking driveways, uneven sidewalks, and settling patios. These are more than just cosmetic issues. They create dangerous trip hazards and direct water toward your property’s foundation.
Operating since 1973, Lamunyon Dry Out & Foundation Repair provides expert concrete leveling and lifting services across many locations in the state. Our team uses advanced polyjacking and foam lifting techniques to restore concrete to its original position quickly and permanently.
Professional Concrete Leveling and Lifting for Manhattan Homes and Businesses
It’s concerning to discover sunken concrete around your property, but our team is here to guide you through the repair and to give you peace of mind. We offer comprehensive concrete leveling solutions designed to address the challenges posed by Kansas’s unique soil conditions.
Fast, Cost-Effective Alternative to Replacement
If the sunken concrete slab under your house is still structurally sound, tearing out and replacing it isn’t necessary. It’s messy, expensive, and time-consuming, and it can leave your yard in disarray for days. Polyjacking offers a superior alternative that typically also costs about half as much as replacement. It’s completed within hours, allowing you to use your driveway or patio almost immediately after the repair.
Correct Uneven Concrete and Trip Hazards
Uneven slabs create significant safety risks for your family, guests, or customers. A sunken sidewalk or a step that’s pulled away from your porch can easily lead to falls and potential liability issues. Our foam lifting process carefully raises the settled concrete back to an even level, eliminating dangerous trip hazards and restoring safe access to your property.
Improve Drainage and Surface Safety
When concrete settles unevenly, it often alters the surface’s natural slope, causing water to collect in low spots or to drain towards the foundation. This poor drainage can lead to soil erosion, basement leaks, and structural damage. By leveling the concrete, we restore the proper pitch so rainwater flows away from your home, which also helps prevent icy patches in the winter.
Long-Lasting Results With Minimal Disruption
Unlike traditional mudjacking, which relies on a heavy cement slurry that can put more pressure on weak soil, our polyurethane foam is lightweight and durable. The foam expands to fill voids and cracks, compacts the loose soil beneath the slab, and cures into a solid, waterproof foundation. This engineered solution is a permanent fix with minimal disruption to landscaping and needs only small, dime-sized injection holes.
Signs You Need Concrete Leveling Services
Expansive clay soil in Kansas frequently shifts with changes in moisture brought on by the weather, which can cause your foundation and exterior slabs to settle unevenly over time. Recognizing the early warning signs of sinking concrete can save you from more extensive and costly repairs down the road.
Sinking or Uneven Sidewalk
If you notice that sections of your walkway have dropped below the adjacent slabs, creating a noticeable lip or step, your concrete is settling. This unevenness not only looks unsightly but also creates a potentially dangerous tripping hazard for anyone approaching your home.
Sunken Driveway or Garage Floor
A common issue in Manhattan homes is a driveway that’s sunk where it meets the garage floor, creating a harsh bump when you drive in. And if your garage floor itself is cracking and sloping toward the center or the walls, the underlying soil has probably washed away or compacted.
Pooling Water Near Concrete Slab
After a heavy rain, take a look at the concrete surfaces around your property. If water is gathering in large puddles on your patio or driveway instead of running off, the slab has lost its proper grade. This pooled water can accelerate concrete deterioration and seep into the soil below, worsening settlement.
Cracked or Tilting Patio
Unfortunately, patios are highly susceptible to soil erosion and settling. If your patio slab has developed large, widening cracks or is visibly tilting away from or toward your house, the supporting base has been compromised. Leveling the slab helps close these gaps and restore a flat, usable outdoor living space.
Uneven Steps or Entryway
Concrete steps that have pulled away from your porch or foundation indicate significant soil movement. When the bottom step sinks, it increases the riser height, making the stairs awkward and dangerous to navigate. Foam lifting can raise the steps back into their proper alignment with the porch.
Interior Floor Settlement
Concrete settlement isn’t always limited to the outdoors. If you have a slab foundation or a concrete basement floor, you might notice the floor sloping, baseboards separating from the floor, or interior doors sticking. These are signs that the soil beneath your home is failing to support the slab’s weight.
Our Polyjacking and Foam Lifting Solutions in Manhattan, KS
Lamunyon provides dependable concrete leveling and lifting solutions using advanced polyjacking and foam lifting methods. Instead of relying on outdated, heavy mudjacking techniques, we use high-density polyurethane foam to raise and stabilize sunken slabs. This modern, improved approach allows us to lift the concrete back to its original position precisely while filling voids and strengthening the underlying soil at the same time. The result is a clean, efficient, and long-lasting repair that protects both your property’s value and your safety.
Inspection and Site Evaluation
We start with a thorough assessment of the sunken concrete and its surroundings. We identify the root cause of the settlement, whether it’s soil erosion, poor compaction, or expansive clay, to ensure our repair addresses the underlying issue.
Precision Lift Plan
Based on our evaluation, we’ll develop a customized plan for lifting the slab. We determine the optimal locations for the injection holes to make sure the polyurethane foam is distributed evenly and provides the precise amount of lift required.
Foam Injection and Slab Raising
Our skilled technicians carefully drill the small access holes, usually less than an inch in diameter (about the size of your pinky finger). They then use specialized equipment to inject the two-part liquid polyurethane mixture into the voids under the slab. They also closely monitor foam expansion, controlling the flow to raise the concrete slab as close to its original grade as possible without causing additional damage smoothly and accurately.
Surface Check and Final Adjustments
The polyurethane foam cures and hardens within 15 to 30 minutes, creating a strong, waterproof, and lightweight base that permanently supports the slab. Once the slab is lifted, our professionals perform a rigorous surface check using levels to confirm that the concrete is as even as possible, and that proper drainage slopes have been restored. They make any necessary final adjustments for optimal results.
Cleanup and Completion
After the lifting is complete, we patch the small injection holes with a durable concrete mix. We thoroughly clean the work area, leaving your property neat and the concrete ready for almost immediate use.

Frequently Asked Questions
Polyjacking is a modern concrete leveling method that involves injecting high-density polyurethane foam beneath a sunken concrete slab. The foam expands to fill voids, compact loose soil, and lift the concrete back to its original level position.
Yes, foam lifting (polyjacking) is generally considered superior to traditional mudjacking. Polyurethane foam is much lighter, so it doesn’t add excess weight to already weak soil. It also requires smaller injection holes, cures in minutes rather than days, and is waterproof, meaning it won’t wash away over time like a mud slurry can.
It’s designed to be a long-lasting, permanent solution. The high-density foam is very durable, doesn’t degrade in the soil, and is resistant to moisture and chemicals. If the underlying drainage issues are properly addressed, a polyjacking repair can last for the life of the concrete slab.
The cost of concrete leveling depends on the size of the sunken slab, the extent of the settlement, and the amount of polyurethane foam required to lift it. Polyjacking is typically much more cost-effective than tearing out and replacing the concrete, often saving homeowners up to 75% on repair costs.
Concrete sinking in Manhattan, KS, is primarily caused by the region’s expansive clay soils. These soils swell significantly when wet and shrink when dry, creating empty spaces under the concrete. Poor soil compaction during construction, soil erosion from poor drainage, and the earth’s natural settling over time can also all lead to unsupported and sinking concrete slabs.
