What Is Concrete Lifting?
Concrete lifting, sometimes called slab jacking or mudjacking, is the process of raising sunken or uneven concrete back to its original position without demolition. Instead of breaking out an old driveway or walkway and pouring new concrete, a trained crew drills small access holes, injects a lifting material beneath the slab, and the concrete rises back into place. The holes are patched, and the surface is ready for use within hours.
In Rochester, Minnesota, the ground moves. Freeze-thaw cycles through our winters cause soil to heave and compact, clay-heavy soils in Olmsted County expand when wet and shrink when dry, and tree roots near older driveways work their way under slabs over decades. The result is concrete that was perfectly level at pour time sitting two or three inches lower on one edge five years later. A tripping hazard on your front walk or a drainage problem on your garage apron can develop quickly once the soil underneath starts moving.
At Pouring Praises, we use polyurethane foam lifting for most residential and commercial concrete lifting projects in Rochester. The foam is injected through small ports, expands to fill voids beneath the slab, and cures hard within minutes. It does not wash out or compress over time the way traditional mudjacking material can. For older slabs where polyurethane lifting is not appropriate, we evaluate the full picture and recommend the path that makes the most sense for the project and your budget.
Rochester’s frost depth runs around 60 inches. Slabs with soil voids beneath them can shift considerably between October and March, then again as the ground thaws. Addressing settlement early prevents hairline cracks from becoming structural breaks.
Concrete Lifting Done Right in Rochester
A list of reasons means nothing without work to back it up. Here is what separates our concrete lifting work from the alternatives.
We Diagnose Before We Drill
Before any hole goes into your concrete, we assess the full picture: slab thickness, soil condition, drainage patterns, and how the slab relates to adjacent surfaces. Injecting foam into a slab that is too deteriorated to hold a lift wastes your money. We tell you honestly when lifting is the right call and when replacement makes more sense. Rochester homeowners have told us this straight talk saved them from paying for work that would not have held.
Polyurethane Foam That Lasts Through Minnesota Winters
Traditional mudjacking uses a slurry mix that can wash out or compress over time, especially in soils that see repeated freeze-thaw cycles. The polyurethane foam we use for lifting expands on contact, fills every void, and cures to a rigid state within minutes. It is impervious to water, does not shrink, and holds its shape through the temperature swings Rochester puts everything through between November and April.
Minimal Disruption, Same-Day Use
The access holes we drill are typically 5/8 inch in diameter. They are patched with material that blends to the surrounding concrete and is ready to walk on or drive over within hours of the job finishing. Compare that to a full slab replacement: saw cutting, breaking out, hauling debris, subbase work, forming, pouring, and then waiting 7 to 28 days before the surface is safe for vehicle traffic. For a driveway or sidewalk in active use, the difference in disruption is significant.

Walk the Site With Us →Our Concrete Lifting Process
Three steps, start to finish. Most residential concrete lifting projects in Rochester are complete in a single visit.
Assessment and Hole Placement
We walk the affected slabs with you, identify the low points, and map where the voids beneath the concrete are most likely located. Access holes are drilled in a pattern designed to achieve even lift across the full slab. We avoid drilling near cracks, control joints, or edges where the slab is thin. For slabs near downspouts, tree lines, or areas with known drainage issues, we take extra care identifying the underlying cause so the lift holds long term. The drill takes a few minutes per hole, and the concrete is undisturbed except for the small opening.
Injection and Lift Monitoring
Two-component polyurethane foam is injected through the access holes under controlled pressure. As the foam expands, it fills soil voids and begins pressing the slab upward. We monitor the lift in real time with level gauges and stop the injection at the correct height. Lifting concrete is not like inflating a balloon, and overlifting is a real risk on older slabs with irregular bottoms. Our crew has done enough Rochester-area projects to develop a feel for how different soil conditions respond, and we work conservatively, checking level between injections rather than pushing for full correction in one shot.
Hole Patching and Final Walk-Through
Once the slab is at the correct elevation, each access hole is filled with a cementitious patching compound matched to the surrounding concrete surface as closely as possible. The patches cure quickly, and the slab is typically safe for foot traffic within a few hours. For driveways, we advise waiting until the following morning before driving on the lifted area to allow the polyurethane foam underneath to reach full cure strength. Before we leave your Rochester property, we do a final walk with you, confirm the elevation correction met the goal, and answer any questions about ongoing maintenance or drainage improvements that might prevent future settling.

Concrete Lifting FAQ
How much does concrete lifting cost in Rochester, MN?
Concrete lifting cost depends on the number of slabs being lifted, the severity of the settlement, and how much material needs to be injected to fill the voids beneath. Most residential projects in Rochester, including a settled driveway apron, a section of sidewalk, or a patio with one or two low sections, fall in a range that is significantly less than full slab replacement. We provide a free quote for every concrete lifting job before any work begins, so you know the exact scope and cost upfront. There are no separate trip fees or material surcharges added after the fact.
How long does concrete lifting last?
Polyurethane foam lifting is a long-lasting solution when the underlying soil conditions are stable. In areas with solid subbase and no ongoing drainage or erosion issues, lifted slabs can remain level for ten years or more. The foam itself does not degrade over time or wash out the way traditional mudjacking slurry can. In areas with ongoing soil movement, such as spots near tree lines, downspouts, or known fill soil, we discuss drainage improvements at the time of the project because addressing water management alongside the lift significantly extends how long the correction holds.
How long before I can use the concrete after lifting?
The patching compound on the access holes cures within a few hours, and foot traffic is generally safe on the same day. For driveways and areas that will see vehicle weight, we recommend waiting until the following morning to allow the polyurethane foam underneath to reach full cure strength. This is a conservative guideline, and in practice the foam reaches working strength within 15 minutes of injection. The one-day wait is a precaution for heavy loads on recently lifted slabs. Compare this to new concrete, which requires 7 days minimum before light vehicle traffic and 28 days before full cure.
Can all settled concrete be lifted, or are some slabs too far gone?
Concrete lifting works best on slabs that are structurally sound but have settled due to soil voids or compaction beneath them. If a slab has major cracking, spalling, or has broken into multiple pieces with significant displacement between them, lifting is unlikely to produce a good result, and replacement is the more honest recommendation. We assess every slab before quoting. Cracking that follows control joints and is in good alignment is often compatible with lifting. Random cracking across the face of the slab is a sign the concrete may not hold the lift long term. We will tell you which situation you are dealing with before any money changes hands.
Does concrete lifting work on steps and stoops?
Yes, concrete steps and stoops are among the most common concrete lifting projects we handle in Rochester. Settled front steps are both a safety hazard and a curb appeal problem, and lifting them is almost always less disruptive than demolishing and replacing the entire stoop assembly. The process is the same: small access holes, foam injection, level monitoring, and patching. Steps that have pulled away from the house foundation and settled independently are good candidates. Steps that have cracked through the riser face or tread are evaluated on a case-by-case basis. Contact us with photos if you are not sure whether your steps are a good candidate for lifting.
Ready to Fix That Settled Concrete?
Sunken concrete does not fix itself. Over time, settlement gets worse, drainage problems compound, and what starts as a minor trip hazard becomes a more serious repair.
