We pour commercial concrete in Lawrenceville and across metro Atlanta: building slabs, parking areas, loading pads, dumpster pads, sidewalks, curbs and the approaches that tie a property to the street. Retail trade, education and health care employ more people here than anything else, so much of the commercial building in town serves stores, schools and clinics. Those surfaces take delivery trucks, steady foot traffic and cars turning on the same spot all day. We set slab thickness, reinforcement and joint layout for the load the property will really carry. A slab that suits an office walkway will crack under a box truck, and tearing it out costs far more than pouring it right.
The land here is hilly, with 181 feet of local relief within a few miles, and it changes from one block to the next. Pacolet soil, which drains well, is the dominant type locally, but we never take that on faith. Every site gets graded and tested on its own before work starts. With about 55 inches of rain a year, water decides a lot: the slope of the lot, the strength of the subgrade, and where runoff goes once it leaves the slab. Get those right and a commercial surface stays level and useful for years. Call us for a free estimate.
What moves the number on a slab is mostly what sits under it and what it has to carry. A slab for foot traffic and shelving needs less depth and steel than one taking forklifts or delivery trucks. Grading matters too. Gwinnett County is hilly, so some sites need cut, fill and compaction before any forms go down. Load, subgrade, reinforcement and finish are what set the price. Call for a free estimate.
A driveway fails from the bottom up. Soft spots in the base, water running under the edges and missing control joints crack most of them, not the concrete itself. We strip organic soil, compact a graded stone base, and set rebar or wire mesh so the slab stays in one plane. Pacolet soil, the most common type in the county, drains well, but it varies, and with about 55 inches of rain a year we pitch every driveway to shed water.
Interior floors for shops, warehouses and retail space live or die on flatness and curing. We lay a vapor barrier over compacted base, reinforce for the loads the floor will actually see, and saw-cut joints early so shrinkage cracks land where we put them. Finish follows use: a hard steel trowel for carts and foot traffic, sealed or polished surfaces for showrooms. What usually goes wrong is rushed curing, which leaves a soft, dusty top layer that wears through fast.
With the median home here built in 1987, plenty of the slabs we see carry decades of wear: settled sections, spalled surfaces, trip edges at the joints. We find the cause before we fix anything. A crack from a washed-out base comes right back if all you do is fill it. Depending on what we find, we rout and seal cracks, patch spalled areas, or cut out the bad section and pour new concrete with reinforcement doweled into the old slab.
We walk the property before anything gets drawn. Gwinnett County is hilly, with 181 feet of local relief within a few miles, and it changes block to block, so we shoot grades across the whole footprint and mark where water wants to go. Pacolet soil dominates here and drains well, but we test your site on its own. We also pin down the load, because a loading dock and a sidewalk need very different slabs. We handle the permit.
Most slab failures start under the concrete, not in it. We strip topsoil and roots down to firm subgrade, then proof-roll it with a loaded truck to find soft spots before a slab does. Bad pockets get dug out and backfilled. A crushed stone base goes on top, compacted in lifts and checked as we go. The area sees about 55 inches of rain a year, so we grade every surface to shed water away from the building, never toward it.
Forms go up in lumber or steel, set to a string line and staked hard enough that wet concrete cannot push them out of true. Inside a building, a vapor barrier goes down over the base so ground moisture stays out of flooring and finishes. Reinforcement follows the load: welded wire for light-duty areas, tied rebar grids where trucks and forklifts run. Every bar sits on chairs so it ends up mid-slab. Steel lying on the dirt does nothing.
Pour day gets scheduled around the weather, not the other way round. We order the mix for the job, with strength and additives matched to the slab and the conditions that morning. Trucks are timed so each load meets the last one while it is still workable, because a cold joint in the middle of a floor is a crack waiting to happen. Concrete gets placed close to where it lands, vibrated around the steel and struck off to grade.
Timing matters more than technique here. Finish too early and bleed water gets trapped under the surface, where it later flakes off as scaling. Too late and the slab fights back. We bull-float, wait for the sheen to leave, then finish to the use: a broom texture outside for grip, a steel trowel for warehouse floors, stamped or decorative work where looks count. Control joints go in by tool or saw the same day, so the slab cracks where we choose.
Curing is where strength is actually made, and it is the step most crews rush. Concrete needs water to keep hardening, so we keep the surface wet or covered under curing compound or blankets through the first several days. Let it dry out fast and you get shrinkage cracks and a weak, dusty top. Average highs run around 72°F and lows near 53°F, but any given week can differ, so we pick the cure method before the pour. Traffic stays off until the slab is ready.
Sealing protects what the earlier steps built. Once the slab has cured enough to let moisture escape, we apply a penetrating sealer on exterior walks and driveways, or a film-forming acrylic on stamped and decorative surfaces to hold the color. Warehouse floors get a densifier that hardens the top and cuts dust. Sealer put down on damp concrete clouds white and peels, so we wait. Resealing on a schedule keeps oil, salt and water out. Call us for a free estimate on your project.
The right system starts with what the slab has to carry. A sidewalk in front of a retail unit, a loading apron that takes box trucks every morning, and a warehouse floor under racking and forklifts all call for different thickness, different mixes and different reinforcement. Wire mesh holds light pedestrian surfaces together. Rebar set on chairs gives structural strength where wheel loads concentrate, and thickened edges carry weight at the perimeter. Fiber in the mix helps control surface cracking across large pours. Decorative and stamped finishes can go over any of these, but they sit on top of the structure, never in place of it.
Our choice comes from the site, not from a catalog. Pacolet soil is the dominant type in Gwinnett County and it drains well, but it varies from one part of the county to the next, so we test every property before we specify anything. Grade matters just as much. The county has 181 feet of local relief within a few miles, which means slope has to be measured on each lot rather than assumed, and about 55 inches of rain a year will find any low spot a slab leaves behind. We set the subbase, slope and joint layout around those conditions, then choose materials to match. Call for a free estimate on your project.
Most of what sets the price of a commercial slab is already sitting on the property before anyone brings a truck. Square footage matters, but two jobs of the same size can bid very differently. These are the factors we look at, and most of them you can check yourself on a walk around the site.
| What changes the price | Which way | Why |
|---|---|---|
| Old concrete or asphalt still in place | costs more | It has to be broken up, loaded and hauled off before we can form anything new. |
| How a truck reaches the work | costs less when the path is open | A clear approach lets us pour straight from the chute. A fence, a tight gap between buildings or soft ground means pumping it in. |
| Slope across the site | costs more on steeper ground | Gwinnett County is hilly, so many sites need cutting, filling or taller forms to set a level slab. |
| Slab thickness | costs more as it gets thicker | Delivery trucks, forklifts and equipment call for more depth, which means more concrete and more base. |
| Reinforcement | costs more with heavier steel | Rebar takes time to lay out and tie, and the loads on the slab decide how much goes in. |
| Where the water goes | costs more if it pools or runs toward a building | Drains or regrading have to come before the pour, or the surface fails early. |
| Roots, stumps or buried lines | costs more | Anything underground has to be located, then cleared or worked around. |
| Decorative or stamped finish | costs more than a broom finish | Patterns and color add labor and time on the day of the pour. |
When you compare bids, make sure they describe the same job. Look for slab thickness, base depth, the size and spacing of the reinforcement, who removes the old material, and whether the permit is included. A lower number often means one of those was left out.
There isn't one number that fits every commercial walk. Width comes from the approved site plan, the foot traffic the property expects and the accessibility rules for the route between parking, entrances and the public sidewalk. We build to the drawings and check running slope and cross slope against them before we pour. We handle the permit. If your plans are still loose, bring them along when you call for an estimate.
Terms belong on paper, agreed before anyone breaks ground, so ask us to put them in writing with the estimate. Concrete also needs the owner's side of the bargain: joints sealed, drainage kept clear, and trucks and forklifts kept off a new slab until it has cured. We explain what the surface needs to hold up and why the control joints go where they do. That way you know exactly what you are paying for.
Ask any contractor bidding your Lawrenceville project for current license and insurance paperwork, and read it before you sign. Check that the business named on it matches the one on the contract. Check that the coverage dates run past your finish date. On commercial property, your landlord, lender or general contractor may also want a certificate naming them. Asking early is normal, and a serious bidder expects it.
We pour flatwork and structural concrete for property that sees steady traffic. That means building slabs, sidewalks and entry walks, curb and gutter, dumpster pads, loading areas, equipment pads and retaining walls. Retail trade and health care are two of the area's largest industries by employment, which translates into storefront walks, clinic entrances and the parking areas around them. Where a broom finish looks too plain, we do stamped and decorative work too.
Price follows the wall's length, what it holds back, the footing, the reinforcement and how easily a truck can reach the site. Gwinnett County is hilly, so the grade behind the wall matters as much as the face you see. With about 55 inches of rain a year, drainage behind it is part of the job, not an extra. At that height, engineered drawings may be required. Call for a free estimate; the number comes from your site, not a chart.
As deep as the engineer's drawings and the soil say, and no deeper for show. Footing depth depends on the building's loads, the bearing capacity found in testing and how far the grade falls across the lot. Pacolet soil, which drains well, is the county's dominant type. It still changes from block to block, so every site is tested on its own before we dig. We handle the permit and the inspections that follow.
