A concrete slab is the flat, poured base that everything else sits on: a garage floor, a shed pad, a patio, the floor of an addition. In Auburn we pour slabs for residential property owners and for smaller commercial jobs, and the work looks simple from the street. It isn't. A slab that stays flat and uncracked for decades comes from what happens underneath it and inside it, long before anyone sees a finished surface. That hidden part is where most of our attention goes.
Every project starts with the ground. Pacolet soil, which drains well, is the dominant type across Gwinnett County, but it changes from one lot to the next, so we test each site individually before work starts. From there we set the grade, compact the base, place the reinforcement the slab calls for, and set forms to the finished height. Pour day is the short part. The preparation behind it takes longer, and it should. Once the concrete is placed, we finish the surface to suit its use: broomed for grip outside, troweled smooth inside.
Most failures we get called to look at trace back to a handful of causes. The base wasn't compacted, so the slab settled unevenly and cracked along the low side. Water had nowhere to go, and with about 55 inches of rain a year, it finds the weak point. Reinforcement was left out, or it sat on the dirt instead of up in the pour where it does its job. Control joints were cut too shallow or too far apart. None of this shows on the first day. It shows a year or two later.
Getting it right costs time more than anything else. It means an extra day on base work when the ground needs it. It means waiting out a storm rather than pouring into one, and ordering the mix that suits the slab instead of whatever is easiest to get delivered. It means cutting joints at the right hour, not the convenient one. A homeowner would never spot any of these as a line item on a bill. Every one of them decides whether the slab lasts or gets torn out early.
Slabs are the center of our work, and the same attention goes into driveways, patios and decorative concrete, stamped surfaces included. A useful estimate starts with what the slab has to carry: a parked truck, a workshop full of heavy tools, a hot tub, the walls of a room addition. Each of those calls for its own thickness and its own reinforcement, and the ground under it matters as much as the load on top. If you have a project in Auburn, call us for a free estimate and tell us what's going on it.
A slab quote is only as good as the measurements behind it, so ours come from your site, not a chart. We look at the footprint, the load the slab will carry, how much the grade has to change, and what base the ground needs underneath. Pacolet soil is well drained and common across Gwinnett County, but it varies from lot to lot, so we test every site before a number goes on paper. Call for a free estimate.
Driveways fail at the edges and the joints first. We compact a crushed stone base, set steel reinforcement on chairs so it sits in the middle of the slab instead of on the dirt, and thicken the edges where tires roll off. Control joints are cut so cracks land where we put them. With about 55" of rain a year here, every driveway gets pitched to shed water away from the garage. Finishes run from plain broom to stamped.
Interior floors live or die on what is under them. We lay a vapor barrier over a compacted base so ground moisture does not wick up into whatever goes on top later. Reinforcement is wire mesh or rebar, depending on the load. For floors left bare, we power trowel to a hard, tight surface, then seal or stain it if you want. Garage floors get a slight fall toward the door, so water off a car runs out instead of pooling.
Not every cracked slab needs to come out. Hairline shrinkage cracks can be routed and sealed. A slab that has sunk or tipped usually has a void underneath, often from a downspout or a washed-out base, and that has to be dealt with before any repair on top will hold. We find the cause first. If the concrete is sound, we fix it. If it is broken through and moving, we say plainly that replacement is the better spend.
Sidewalks are narrow slabs, and narrow slabs crack wherever they are not given a place to. We form walks on a compacted base, cut joints at regular intervals, and slope the surface just enough that rain runs off to the side. Where a walk meets a driveway, a step or the house, we set an isolation joint so each piece can move on its own. A broom finish for grip is standard. Stamped or colored decorative borders are an option.
Before anything is dug, we walk the property and watch where water goes. That matters here: the area sees about 55 inches of rain a year, and a slab set in the wrong spot sits in it. Pacolet soil, which is well drained, is the dominant type in Gwinnett County, but it varies from lot to lot, so we test every site individually. We also look for buried lines, tree roots and old fill that will settle.
We strip topsoil and anything organic down to firm ground, because roots and loam rot away and leave voids under a slab. Soft spots get dug out and replaced. Then comes a gravel base, packed in lifts with a plate compactor rather than dumped and raked flat. The grade gets a slight fall away from the house. Most cracked driveways fail here, not at the surface: the base was thin, wet or never compacted.
Forms go in next, set to string lines so the top of the slab lands where the grade plan says it should. We use straight lumber, staked and braced, since a form that bows under wet concrete bows the finished edge with it. Reinforcement depends on the project: welded wire mesh or rebar tied in a grid. Either way it sits up on chairs, inside the slab. Steel lying on the gravel does nothing structural at all.
Concrete comes off the truck and goes into the forms as close to its final spot as the chute or pump can place it. Dragging it long distances with rakes separates the stone from the paste. We watch the water closely. Extra water makes concrete easy to spread and weak once it sets, so it doesn't get added to save effort. The surface is screeded level with a straightedge before bleed water starts to show.
Timing decides this step. We bull float right after screeding, then wait for the bleed water to leave before edging, jointing and troweling. Working that water back into the top gives a dusty, flaking surface later. Control joints are tooled or saw cut so cracks follow a straight line we chose. Driveways get a broom finish for grip. Stamped and decorative work happens now too, pressed in while the concrete still takes an impression.
Fresh concrete gains strength by holding onto its water, not by drying out. Once finishing is done, we keep the surface damp, either with a sprayed curing compound or with covers that hold moisture in. Average daily highs here run around 72°F and lows around 53°F, which is workable, but a hot, windy afternoon still pulls water from the top fast. Keep cars off until we tell you the slab is ready for them.
A sealer is the last coat, applied after the slab has cured, not before. On plain broom-finished driveways and patios, a penetrating sealer soaks in and slows down water, oil and staining without changing the look. Stamped and colored surfaces usually get a film-forming sealer that brings the color up and adds some sheen. Neither lasts forever. Traffic and weather wear sealers down, so a surface that sheds water well today will need another coat eventually.
Two slabs the same size can come in far apart on an estimate. The difference is almost always the site, not the concrete, and most of it you can see for yourself by walking the property.
| What changes the price | Which way | Why |
|---|---|---|
| An old slab, patio or driveway already in place | costs more | It has to be broken up, loaded and hauled off before any forming starts. |
| A mixer truck that can back straight up to the forms | costs less | The truck pours directly. Narrow gates, fences or a yard the truck cannot cross mean a pump or wheelbarrows, and that is extra labor. |
| Roots, stumps or buried debris under the work area | costs more | Anything soft or organic has to come out and be replaced with compacted base, or the slab settles over it. |
| A slab that will carry a vehicle, a shop or a hot tub | costs more | Heavier loads call for a thicker slab and more steel reinforcement than a walkway does. |
| Water that pools or runs toward the pad | costs more | With about 55 inches of rain a year, we grade for runoff first and sometimes add drains before the pour. |
| Ground that slopes across the footprint | costs more | The low side needs more fill and deeper forms to bring the slab level. |
| A stamped or decorative finish | costs more | Pattern, color and sealer add hours of work after the base slab is poured. |
| Firm, level ground that drains on its own | costs less | Pacolet soil, common across Gwinnett County, usually drains well. It varies, so we test every site before work starts. |
Lining up competing bids, check that each one names the same thickness, the same reinforcement and the same base under the slab. See whether removal, haul-off and grading are written in or left out. A lower bid that skips the base or the steel is pricing a different slab.
We cut wet. A saw running with water keeps dust down at the blade, and we mist broken concrete before it gets loaded so it does not drift onto cars, porches or open windows. Heavy breaking stays inside normal working hours. We lay protection where equipment crosses the lawn, keep a clear path to your door, and haul debris off as it comes up instead of stacking it for days.
Yes. Wire mesh comes in standard sheets, and we cut, lap and tie those sheets to fit the shape of each slab, including curves, notches and odd corners. Where a project needs more than mesh can give, such as a driveway carrying heavy vehicles, we switch to rebar laid on a grid sized for that load. Reinforcement is chosen per project, not pulled from a default. Tell us what the slab has to carry.
Planning the pour around your hours does most of the work. We section the job so part of a lot or walkway stays open while another part is formed, poured and curing, and every active area is fenced and coned off. Delivery trucks and pumps get staged away from customer traffic. Before work starts, we walk the site with whoever runs the business and agree on entrances, parking and what stays open each day.
Outside Auburn, we work in Lawrenceville and the other metro Atlanta towns listed on this page, all on the same terms. Same crew, same materials, same standards for site prep and reinforcement. The neighborhood matters less to us than the site itself. A driveway, patio or commercial slab gets the same testing and planning wherever it sits. If you are not sure your property falls inside our area, call and ask.
That depends on the site, so we price it after seeing it. Wall length, how much soil it holds back, drainage behind it and access for the truck all move the number. Pacolet soil is the dominant type in the county and drains well, but it varies from lot to lot, so every site is tested individually before work starts. A wall that height also needs a proper footing and reinforcement. Call for a free estimate.
Mostly the flat work a business leans on every day: parking areas, sidewalks, loading pads, dumpster pads, entry walks and interior slabs for new construction or additions. We also pour decorative and stamped surfaces for storefronts and patios where appearance matters as much as structure. Shops, offices, clinics and schools across Auburn all need the same basics. A surface that drains, carries its load and holds up. Call and describe the project.
