Concrete Leveling & Mudjacking in Atlanta, GA
Atlanta Concrete Services lifts sunken concrete back to level with mudjacking and polyurethane foam injection, usually for a fraction of what replacement costs. We level driveways, sidewalks, patios, porch landings, pool decks and garage floors, then seal the joints so the problem does not come right back.
Most settled slabs we see in Atlanta have the same story. Builders backfilled around the house with loose clay that compacted over time, downspouts dumped roof water at the slab edge, or a stump and construction debris were buried under the yard and slowly rotted. With close to 50 inches of rain a year moving through that soil, voids open up under the concrete and the slab drops into them.
We level concrete in Dunwoody, Brookhaven, Sandy Springs, Smyrna, Decatur, Tucker, Duluth, East Point and College Park, with service across the wider metro & more. Before deciding between lifting and replacing, it helps to understand why concrete cracks in Atlanta in the first place.
Why Choose Atlanta Concrete Services
Concrete Leveling Services
Mudjacking (Slabjacking)
A driveway panel that tips toward the garage, or a walk that has dropped an inch at a joint, can usually be raised in place. We drill small holes, pump a cement-based slurry underneath and lift the slab slowly back to grade while filling the void beneath it.
Leveling and repair work generally runs $3 to $8 per square foot, well below the cost of tearing out and pouring new.
Sidewalk Trip Hazards
A raised or sunken sidewalk edge is how people trip, and inside the City of Atlanta the property owner is responsible for fixing the walk in front of the house once notice arrives. If the panel dropped rather than heaved, we can often lift it flush with its neighbor instead of replacing it.
Panels pushed up by roots need a different fix, usually panel replacement through our sidewalk and walkway crew, since lifting cannot lower a heaved slab.
Polyurethane Foam Lifting
For slabs over soft clay or where we want the lightest possible fill, we inject expanding polyurethane foam through holes about the size of a nickel. It weighs far less than slurry, so it does not add much load to soil that is already weak.
Foam cures in minutes, which means the slab is often usable the same day.
Void Filling at Downspouts
Hollow-sounding concrete or a gap you can stick your fingers under near a downspout means water has been washing the clay out. We fill the void before the slab cracks, and then reroute or extend the downspout so it does not happen again.
This is one of the cheapest fixes we do, and it prevents some of the most expensive damage, especially where the void runs back toward the house foundation.
Driveway, Patio & Porch Lifts
A patio sloping back toward the house, a porch landing pulling away from the steps or a garage apron that has dropped below the driveway all fall into this category. We lift each section in small increments while watching level lines so the panels end up flush and draining correctly.
Badly cracked or crumbling slabs are better candidates for a new concrete driveway or patio, and we will say so instead of selling you a lift that will not hold.
Joint & Crack Sealing
Open joints let every storm send more water under the slab. After lifting, we patch the drill holes to blend with the surface and seal joints and cracks with a flexible sealant.
That last step is what keeps a leveled slab level.
How Slab Lifting Works
Inspect & Diagnose
We check how far each section has dropped, look for the cause, whether downspouts, roots or old fill, and decide if lifting will last. You get a written price per area.
Drill Access Holes
We drill small holes in a pattern across the slab. Mudjacking holes are a bit larger than foam holes, and neither weakens the concrete.
Lift & Fill
We inject slurry or foam in stages and lift gradually, checking with levels so the slab does not crack or overshoot. The material fills the void and supports the slab from below.
Patch, Seal & Fix the Cause
We patch holes, seal joints and cracks, and correct the drainage that caused the settlement. Most jobs are done in a few hours.
Leveling & Mudjacking FAQs
How much does concrete leveling cost in Atlanta?
Leveling and concrete repair typically fall in the $3 to $8 per square foot range. Replacement with removal, by comparison, runs $10 to $16 for a driveway, so lifting usually saves a lot.
Mudjacking or foam, which is better?
Mudjacking is often more economical on larger voids. Foam is lighter, uses smaller holes and cures faster, which can help on weak clay. We recommend one based on your slab and soil.
How long does leveled concrete last?
If the cause is fixed and joints are sealed, many lifted slabs stay level for years. If water keeps washing under the slab, it will settle again, which is why we spend as much time on gutters and grading as on the lift itself.
Can every sunken slab be lifted?
No. Slabs that are broken into many pieces, crumbling or heaved by roots are not good candidates, and we will tell you so up front.
Will lifting fix my sidewalk notice from the city?
If the problem is a dropped panel, lifting it level can resolve the trip hazard. Work in the right-of-way still needs ATLDOT approval, which we handle.
How soon can I drive on it?
Foam-lifted slabs are often usable the same day. With mudjacking, we usually suggest waiting about a day before parking on it.
