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.

A-1 Concrete Leveling & Repair in Flint, MI

Q: Who fixes sunken concrete in Flint?

One local crew serves Flint and the surrounding areas, with free on-site estimates.

For qualifying projects, leveling can save up to 70% compared to replacement. Across A-1 locations, most jobs fall between $1,100 and $1,500. For the accurate number in Flint, request a free, on-site estimate from A-1 Flint today.

Q: Mudjacking vs. polyurethane foam: which is better?

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.

Q: What is concrete leveling?

Raising settled concrete back to a safer, more even position without tearing it out. Also called concrete lifting, raising, slabjacking, or mudjacking.

Q: How does concrete leveling work?

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.

Q: How long does concrete leveling last?

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.

Q: Is concrete leveling worth it, or should I just replace it?

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.

Q: Does A-1 Flint lift concrete with foam?

No. A-1 Flint uses its exclusive ControlLevel system to lift concrete, with precision, into a safe, even position. The ControlLevel system pumps a stone slurry grout material (limestone and water) beneath the surface for maximum void fill and long-lasting strength.

Q: Who is responsible for sidewalk repair?

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.

Lift your settled concrete back to a safer, more even position with A‑1's ControlLevel™ system, available throughout Flint and the surrounding areas.

ControlLevel is an excellent option for lifting concrete in many situations, but not all. Your local A‑1 Flint experts will tell you exactly what you need, and how much it could cost, with your free, on-site estimate.

Lift it if…

It's settled or uneven but still solid
Water pools or runs the wrong way
It has cracks but the slab is still mostly intact
The problem is where the slab sits, not the slab breaking down

Replace it if…

It's crumbling or very badly deteriorated
It is spalling, flaking, or chipping, and you want it looking new again
The slab itself is broken apart, not just sunken
It was poured incorrectly, with waves or other surface irregularities

Why Concrete Sinks in Flint, MI

LOCAL SOIL Sandy Loam

AVG ANNUAL RAINFALL 34″

NIGHTS AT/BELOW FREEZING 149 nights

PEAK FREEZE-THAW WINDOW November–March

Sunken concrete in areas like Flushing or Swartz Creek 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.

While the causes of sunken and damaged concrete are pretty similar across the greater Flint area, what you're seeing may be completely different than someone up the road.
