A cracked or sunken slab usually tells you something about what is happening underneath it. We repair concrete slabs in Lithia Springs: garage floors, patios, walkways, driveways, and the pads that sit under sheds and equipment. Some damage is only on the surface, like scaling or a hairline crack that opened as the concrete cured. Other damage is structural, where a section has dropped, lifted or split clean through. Those two problems can look alike from the back step. They need very different repairs.
We start by finding the cause. Every site is tested individually before work starts, because the ground under one slab can behave nothing like the ground under the next. We check how water moves across and around the property, since a downspout emptying against a slab edge will undo a good repair. Then we choose the method: routing and sealing for stable cracks, patching for shallow surface damage, or cutting out a failed section and pouring it back with new reinforcement tied into the old.
The usual failure is a patch laid on top without anyone asking why the slab moved. It looks fine for a while, then the same crack opens beside it, or the filler works loose. With about 50 inches of rain a year, water finds every gap you leave it. Getting it right means fixing drainage and support first, matching materials to the existing concrete, and letting new work cure fully before it carries weight.

Price comes down to what sits under the slab and what goes into it. Subgrade prep, compacted gravel base, slab thickness, rebar or wire mesh, and how close a truck can get to the pour all move the number. So does the finish: broom, smooth trowel or stamped. We test every site before work starts, measure the property, and write the estimate line by line. Call for a free estimate and you will see where each part of the cost comes from.
A driveway fails from the bottom up. We cut out organic soil, compact a crushed stone base, and pour a thicker section where vehicles turn and park. Reinforcement goes in on chairs so it sits mid-slab instead of lying useless in the gravel. Control joints get cut the same day, spaced so the cracks concrete always wants to make happen in straight lines. Finish is broom for grip, or stamped and sealed where you want a decorative surface.
Interior floors in garages, basements, workshops and commercial spaces start with a vapor barrier under the slab, because moisture coming up through bare concrete ruins whatever is laid on top of it. We place reinforcement, pour, and power trowel to a flat, dense surface. From there the floor can stay plain, take a polish, or get a sealer or epoxy coating. Joints are planned around walls, columns and drains so the floor moves where it should.
Cracks, sunken sections and heaved edges nearly always trace back to something underneath: washed-out base, poor compaction, roots, or water pooling against the slab. We find that cause before touching the surface. Hairline cracks get routed and sealed. Settled sections can be lifted and the voids filled. Where a panel is broken through, we saw-cut it out, rebuild the base, dowel into the sound concrete, and pour new. Patching over a bad base just buys a second repair.
Sidewalks look simple and still go wrong: poured on loose fill, left without joints, or pitched toward the house. We set forms to a slight cross slope so water sheds into the yard, compact the base, and tool joints at even spacing so cracking stays controlled. A broom finish keeps them safe when wet. Where a walk meets a driveway, steps or a porch, we tie in cleanly with expansion material so each piece moves on its own.
A cracked or sunken slab is usually telling you something about what sits underneath it. We start there. Before we patch, grind or pour anything on a Lithia Springs property, we work out why the concrete moved: water running where it shouldn't, fill that was never compacted, or a base that washed out over the years. Fixing the surface without answering that question just buys a few seasons. Our repairs are built around the cause, so the slab stays where we leave it.
Every site is tested on its own before work starts, because soil varies from one lot to the next and a guess about the base is how repairs fail. From there we match the fix to the conditions. That means lifting and filling where the slab is sound, cutting out and replacing sections where it isn't, and adding reinforcement where the load calls for it. Driveways, patios, garage floors and walkways each carry weight differently. We treat them that way, with materials chosen for the job in front of us.
Water is behind a lot of slab trouble. With about 50 inches of rain a year, runoff finds every low spot and open joint along an edge, and it carries base material out with it. So drainage is part of the repair, not an add-on. We look at where water lands, where it goes, and whether the grade around the slab is sending it back underneath. Getting that right takes a little longer on the day. It is also the difference between fixing a slab once and fixing it twice. Call us for a free estimate.
On a Lithia Springs slab repair, we start by walking the property and reading what the old concrete is telling us. Cracks that run straight and tight are usually shrinkage. Cracks where a section has dropped point to settling, washout or roots underneath. We check how the slab drains, where water goes when it rains, and whether the base failed or the concrete did. Every site is tested individually before work starts, so the repair is sized to the ground it sits on.
Most slab failures start below the concrete, so this is where we spend the time. Broken sections come out and get hauled off. We dig out soft or organic soil down to firm ground, then bring in crushed stone and compact it in lifts with a plate compactor until it stops moving. The grade gets set so water sheds away from the foundation. Under interior slabs, or anything that will be covered later, a vapor barrier goes down last.
Forms are straight lumber, staked tight and checked with a string line and level, because the finished slab will match whatever shape the forms hold. Then comes the steel. Driveways and slabs that carry vehicles get rebar tied in a grid, while lighter patios may get welded wire mesh or fiber in the mix. Either way, the reinforcement sits on chairs so it ends up in the middle of the slab. Steel lying on the gravel does nothing.
Pour day is about control. We order the mix for the job and check it at the truck, and nobody adds water to make it spread easier, because that is how weak, dusty surfaces happen. Concrete gets placed close to where it belongs instead of being dragged across the forms. It is then screeded flat, bull floated, and consolidated around the edges and steel so no voids are left behind. If rain threatens, the pour waits.
Bleed water has to leave the surface before anyone works it. Finishing too early traps that water near the top and leads to scaling and flaking later. We edge the perimeter and cut or tool control joints so the slab cracks where we choose, not where it wants to. Then the finish goes on: a broom texture for traction on driveways and walks, a smooth trowel for garages, or stamped and decorative patterns with color for patios.
Concrete keeps gaining strength for weeks, and it only does that if it holds onto its water. Right after finishing, we either keep the slab damp or spray on a curing compound. When sun or wind would dry the top faster than the bottom, we cover it. That uneven drying is what causes curling and surface cracks. Foot traffic comes first. Cars wait longer, until the slab has the strength to carry them without marking or cracking.
Once the slab has cured, a sealer keeps water, oil and leaf stains from soaking in. Plain broom-finished driveways usually get a penetrating silane or siloxane sealer, which leaves no film and no shine. Stamped and colored surfaces get an acrylic that deepens the color, though it wears and needs recoating over time. We clean the concrete first, apply thin even coats rather than heavy ones, and keep everyone off until it has dried completely.
That answer belongs on paper, from us and from anyone else bidding the job. A commercial concrete project carries real exposure: heavy equipment, open forms, and crews on your property for days at a time. Before any contract is signed, the contractor should hand over license, insurance and bonding documents that you can check directly with the issuing office. Treat a verbal answer to this question as no answer at all.
Yes. We order the mix to the design the slab calls for, then time the truck to the day the forms, base and reinforcement are ready. A load that sits waiting starts setting in the drum. So the pour is worked out before the plant gets the call: where the truck parks, whether a pump or buggies are needed, and how many hands are on the surface while it is placed and finished.
Ask for the certificates, and ask before any work is scheduled. That is the right habit with every contractor, residential or commercial, and it applies to us the same way. A certificate of insurance should name the carrier and the policy dates. A bond should name the surety. Call those companies yourself to confirm the documents are current. Five minutes on the phone settles it.
Yes, where the work calls for them. Plenty of slab repairs (a cracked patio section, a sunken walkway panel) need no permit at all. Structural work, a new driveway apron, or anything touching the right-of-way is more likely to. We pull what the job requires, build the schedule around inspection points, and keep the approved paperwork on site so an inspector can check forms and reinforcement before any concrete goes in.
Yes. Welded wire mesh comes in standard sheets and rolls, and we cut and lap it to fit the exact footprint of the slab, whether that is a narrow side walkway or an irregular patio. When a project needs a heavier gauge or tighter spacing than the stock product, we order it to that spec. For some loads, rebar is the better reinforcement, and we will tell you so.
Most of the dust comes from cutting, so we saw wet and run vacuums on the grinders. Cutting out only the damaged section, rather than breaking up the whole slab with a jackhammer, keeps both the noise and the work area smaller. We sheet off nearby doorways and vents, agree on working hours with you before the first day, and haul broken concrete away as it comes up instead of piling it in the yard.
