Concrete flatwork in Little Rock, Arkansas

Concrete flatwork in Little Rock, Arkansas

Concrete flatwork in Little Rock, Arkansas runs $5.32 to $15.61 a square foot with us. That covers everything from a plain 4-inch slab with wire mesh up to a fully optioned pour. Hillside drives, 6-inch shop slabs, downtown plazas, and industrial pads get priced by their spec. We pour across Central Arkansas along I-40, from Chenal Valley to the Heights to the Port of Little Rock.

A sloped Chenal Valley drive and a downtown plaza are two different jobs, and each one below gets its own spec. The Arkansas concrete flatwork page covers the work statewide.

How do you build hillside driveways in West Little Rock and Chenal Valley?

Most of the city’s high-end driveway work is in West Little Rock along Chenal Parkway, Pleasant Valley, and Chenal Valley. Many of those lots sit on slopes. Up there, the ridges above Cantrell Road step down toward the river valley. A hillside drive has to shed water and handle freeze-thaw along its downhill edge. It also has to ride out uneven settling. On many of these lots, clay that swells when wet (expansive clay) sits under half the slab and rock sits under the other half.

A good hillside driveway starts with a grading plan, not a pour date. We work with the grading contractor on the cut-and-fill. We make sure the packed fill reaches the planned height and the swales carry water off the pad. Where the grade drops more than a foot or two, stepped footings keep the slab from hanging out over loose fill. Hillside drives usually get a 5 to 6 inch slab with #4 rebar on 18-inch centers, over a 6-inch packed AB-3 stone base. That costs more per foot than a flat lot. Our concrete driveways page covers drives in general, and our flatwork project photos show finished pours.

How does Heights and Hillcrest historic sidewalk and patio replacement work?

The Heights, Hillcrest, and Pulaski Heights have some of the oldest flatwork in town. The sidewalks along Kavanaugh Boulevard went in from the 1920s to the 1950s, and the mixes weren’t consistent. Narrow streets, alleys, and big old trees shape every job.

Historic sidewalks follow the city’s public works specs. That’s a 4-inch slab, a broom finish, set joint spacing, saw-cut control joints, and slopes that meet the ADA standards. Tree roots often lift the old Kavanaugh and Cantrell sidewalks. So we have an arborist trim them before we pour.

Patios run on their own spec, and the price moves with the finish, the steel, and the access. A narrow drive or an alley-only lot adds staging time, and that shows on the quote as labor.

What spec do downtown plaza and Clinton Library district sidewalks follow?

Downtown east of Main Street, from the River Market past the Clinton Library to SoMa, brings steady sidewalk, plaza, and ADA curb cut work. With that much foot traffic, blocking off the work drives the schedule.

Plazas get a commercial spec. Where people and service trucks share the slab, we pour 6 inches of 4,000 PSI air-entrained concrete. That mix has tiny air bubbles in it, so it lives through freezing. The saw-cut joints follow a grid set to the design, and so does the finish. On a busy block we put up barriers, mark an ADA detour, and do the loud demolition early in the morning. Kitchen exits onto River Market service alleys get a 6-inch reinforced pour with a hard trowel finish that stands up to chemicals.

What does Port of Little Rock industrial pad and loading dock work require?

The Port of Little Rock industrial park and the North Little Rock industrial strip, near where I-30 meets I-40, hold the city’s warehouse flatwork. Dock aprons, trailer pads, and forklift floors all get a heavier spec than a home pour.

• Forklift floors: 6 inches minimum of 4,000 PSI concrete, with #4 rebar on 12-inch centers or a welded wire mat picked by the load. The saw-cut joints follow the column grid.
• Loading dock aprons: 8 inches, with steel dowels across the joints at the dock edge so the load passes from slab to slab.
• Staging lots: 8 to 10 inches with a coarse broom finish.

When forklifts need a very flat floor, we check the FF flatness number per ASTM E1155.

What spec governs medical campus walkways?

Little Rock’s hospitals always have walkway, ADA ramp, and drive slab work going. The spec covers four things:

1. ADA slopes checked before the pour, not after.
2. Tactile warning strips colored all the way through and set at the base of every ramp.
3. Broom finishes set for wheelchair and gurney grip.
4. Phasing that keeps emergency access open.

Those slabs get 6 inches of air-entrained concrete per ASTM C260, with #4 rebar on 12-inch centers. The saw-cut joints go on a tight grid. The finish is a medium broom. We plan lane closures and shift changes with the hospital’s building crew, so the drives stay open.

North Little Rock and Maumelle suburban residential flatwork

North of the river, Maumelle, Lakewood and Park Hill in North Little Rock, and Sherwood along Highway 107 carry most of the area’s new-build flatwork. Two jobs lead:

• New-build driveways: a 4-inch slab on welded wire mesh or #4 rebar at 18-inch centers, broom finished. We cut the control joints within about 12 hours of the pour, per ACI 224R guidance.
• Backyard patios in Maumelle, Park Hill, and Lakewood. Our concrete patios page covers patios in general.

How do you prep Arkansas River floodplain subgrade for flatwork?

Parts of downtown, the Port, and the river valley sit on Arkansas River clay laid down by floods (alluvial soil). It holds water in wet seasons and settles unevenly. Flatwork poured on that clay as-is moves through freeze-thaw and wet-dry cycles, and it cracks along the joints within two winters. So we start with a soil engineer’s read of the subgrade, the ground under the slab. We dig down to a stable layer. Then we pack the native soil to 95 percent Proctor, the standard lab density. Then 4 to 6 inches of crushed stone (AB-3 or #57 per Arkansas DOT specs) goes on top, packed just as tight. Where the Pulaski County flood map flags a zone, we raise the slab on stem walls or a post-tensioned base. Any indoor pour gets a 15-mil vapor barrier. We photograph the subgrade prep and send the photos with the final invoice.

Up on the ridges, the river clay gives way to rocky upland at the edge of the Ouachitas. The steps stay the same. Only the dig depth and the stone base change by site.

What does rural barn and horse farm flatwork need in Pulaski, Saline, and Faulkner counties?

Rural land in Pulaski, Saline, and Faulkner counties brings horse farm, cattle, and mixed farm work. Barn slabs, wash bays, and hay storage pours face things a home slab never does:

• Urine and manure acids eating at the top
• High-pressure washdowns
• Heavy wheeled equipment

A horse barn slab gets 6 inches with #4 rebar on 12-inch centers and a hard trowel finish. Then we add a silicate densifier that hardens the top, and we slope the slab to a center drain. Barndominium slabs are their own kind of job. They’re the foundation and the finished floor in one. So they need to be flatter, carry more steel for shop loads, and take a polish or coating later. See our Arkansas barndominium slab page, Pour-4-Polish, and the barndominium and shop slab service.

Scheduling pours around summer storms and winter freeze-thaw

Summer storms off the Gulf can drop an inch of rain on a fresh slab in minutes. From late May through September, they usually hit between 2 PM and 6 PM. So our summer pours start at first light, and the slab reaches initial set before the storms come. The first truck by 6 AM is standard in June, July, and August. Heat also cuts the time we have to trowel a Pour-4-Polish slab flat, so we book those for spring and fall when we can.

Winter flips the problem. Little Rock averages 15 to 25 hard-freeze nights a year, plus the odd ice storm. Every outdoor slab we pour gets an air-entrained mix with 5 to 7 percent air, per ASTM C260. Below 40 degrees, we add an accelerator and cover the slab with insulated blankets until it reaches about 500 PSI. We don’t pour below 25 degrees, or with rain due within 4 hours of finishing.

What does Little Rock flatwork cost?

• Flatwork slab, plain 4-inch with wire mesh up to fully optioned: $5.32 to $15.61 a square foot
• Driveways: $6.96 to $16.43 a square foot
• Patios: $5.30 to $17.72 a square foot
• Hillside drive with drainage work: priced by the grade and drainage, after we see the lot
• 6-inch shop or barndominium slab with rebar: priced by thickness and steel
• Downtown sidewalk or plaza: priced by thickness and finish
• Port pad or dock apron: priced by thickness and flatness spec
• Pour-4-Polish slab: from $6.19 a square foot for the pour, plus from $3.58 for the polish

Access, the ground, the steel, and the thickness move the cost more than the price of ready-mix does. Little Rock jobs run as planned multi-day trips, often paired with work in a nearby county. The drive cost (our trip to your site) is its own line on every quote. The Arkansas concrete driveway cost guide goes deeper on drives.
