Save up to 70% vs. replacement
Most residential ControlLevel™ jobs fall somewhere between $1,100 and $1,500.
The exact cost of any concrete leveling project varies based on factors like: the size of the full affected area, the size of the void beneath, and how far the slab has dropped. Getting a free, on-site estimate gives you an exact price and options to consider so you can make the most informed decision.
In many cases, repairing your concrete by lifting is quicker and more cost-effective than replacement. But, some concrete genuinely does need replacing, and we'll tell you when.

How A-1 Lifts Settled Concrete

ControlLevel™ is A‑1's standard for concrete lifting, refined since 1982. You may have heard concrete leveling called mudjacking, mud jacking, slabjacking, concrete jacking, or polyjacking. Whatever you call it, the goal is the same, and ControlLevel™ is how A‑1 does it: specialized equipment, a limestone-based stone slurry, trained technicians, and a controlled process that responds to the conditions beneath each slab.
Small holes are drilled at carefully selected points, and the stone slurry is pumped beneath the slab at a slow, controlled pace. As empty spaces fill, the technician monitors and adjusts the lift. Once the slab reaches the best practical position, the holes are patched and the work area is cleaned.
Together, those elements give A‑1 greater control over the flow of material and the pace of the lift, helping us raise settled concrete carefully, minimize disruption, and avoid unnecessary tear-out.

Raise settled concrete to a safer, more even position with A‑1's exclusive ControlLevel™ System.

Polyurethane foam leveling, also called polyjacking, for select projects. A‑1 chooses the best method for your concrete.

Seal open joints and cracks to help limit water intrusion while allowing seasonal movement.

Clean built-up dirt, algae, and staining from the concrete you already have.

Seal the surface so water, salt, and everyday wear soak in more slowly. It's the maintenance step that buys a slab years.

Stabilize and support settling foundations. Ask your local A‑1 team about foundation repair options.
Based in Southeast Michigan, your A‑1 team is the exclusive provider of the ControlLevel™ system, lifting settled slabs around Oakland County, East Lansing and Novi and the surrounding areas back to a safer, more even position without the cost and disruption of tear-out and replacement.
Some of the best parts of life in Southeast Michigan are outdoors: places like Comerica Park, Michigan State Capitol and Middlegrounds Metropark. Your own driveway and patio should be as safe as the places around them, so A‑1 levels uneven concrete before a small trip hazard becomes a bigger problem.

Sunken concrete in areas like Ann Arbor or Detroit usually starts below the surface: the soil beneath a slab shifts, erodes, or can no longer support it evenly. Water can enter through open joints, cracks, and slab edges. As it moves through the ground, soil may soften or wash away, leaving empty spaces beneath the concrete. Without consistent support, part of the slab begins sinking. Seasonal freezing and thawing can add movement as moisture in the soil freezes, expands, and later thaws. Drainage problems, poorly compacted fill, tree roots, and burrowing animals may also contribute.
A large portion of the Southeast Michigan area is lake-plain clay and inland loam, a mix — dense lake-plain clay toward Detroit and Toledo that holds water against foundations, and lighter sandy loam inland that can wash and settle as fine grains move. Add the freeze-thaw cycles the Southeast Michigan lake plain sees each winter, and slab edges are especially prone to settling.
While the causes of sunken and damaged concrete are pretty similar across the greater Southeast Michigan area, what you're seeing may be completely different than someone up the road.

A‑1 Concrete Leveling. A‑1 raises settled driveways, sidewalks, patios, steps, garage floors, and pool decks back to level with the ControlLevel stone-slurry system or foam leveling, whichever suits your slab, typically for far less than replacement. One local crew serves Southeast Michigan and the surrounding areas, with free on-site estimates.
For qualifying projects, leveling can save up to 70% compared to replacement. Most jobs fall between $1,100 and $1,500. Your exact number comes from a free on-site estimate.
They're different tools. Mudjacking-style leveling pumps a natural slurry beneath the slab; foam injects an expanding synthetic. A‑1's ControlLevel™ system gives the technician live control of the lift. A‑1 Southeast Michigan offers both and will recommend the right one for your slab.
Mudjacking is the traditional name for lifting concrete by pumping material beneath it. ControlLevel™ is A‑1's modern version: a limestone slurry, specialized equipment, and a slow, controlled lift.
Raising settled concrete back to a safer, more even position without tearing it out. Also called concrete lifting, raising, slabjacking, or mudjacking.
Small holes are drilled in the slab, material is pumped beneath to fill the voids, and the slab is guided back to position. With ControlLevel™, the technician monitors and adjusts the entire lift.
Most repairs can last for the life of your concrete. Longevity depends on the conditions beneath the slab, drainage, and upkeep like caulking and sealing.
If the slab is still solid, leveling usually wins: a fraction of the cost, done in a day. If it's crumbling or structural, replacement is the honest answer, and we'll tell you.
Yes. A‑1 Southeast Michigan offers polyurethane foam leveling, also called polyjacking, for select projects. Foam and ControlLevel™ are different approaches suited to different site and slab conditions.
Usually the adjoining property owner, but rules vary by city. Check your city's sidewalk program; if the repair is yours, A‑1 can level it for far less than replacement.
Often, yes. Frozen ground can limit some lifts, but many projects run year-round. Your local crew will tell you what your slab needs.

* Actual savings vary: "Save up to 70% off the cost of replacement" compares qualifying concrete-leveling projects with the cost of fully removing and replacing the same concrete. Actual savings depend on factors such as the slab, site conditions, project scope, and replacement requirements. Your free estimate provides project-specific pricing.
** Actual time varies: For most jobs, concrete is available the same day for walking and in 24 hours for vehicles once work is complete. Actual timing depends on factors such as the surface, project conditions, weather, and materials used. Check with your local A‑1 technician for details.
