Concrete slab: what moves the price in South Carolina

  • Thickness and mix

    A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).

  • Base and reinforcement

    A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.

  • Truck and pump access

    If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.

  • Small-job minimums

    Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.

  • Finish

    A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.

When South Carolina weather lets you pour

Season matters for concrete slab. For each South Carolina metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for pouring concrete.

Charleston has the longest comfortable season of the metros we cover in South Carolina at 12 months; Spartanburg has the shortest at 6 (April through June and August through October). Rainfall runs from 44 inches a year in Columbia to 54 inches in Myrtle Beach.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.

South Carolina labor market for concrete slab

Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 4 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.87 for South Carolina.

For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $23.73 an hour, which is 13% below the national $27.41. The middle half of them earn between $21.74 and $29.70 an hour. BLS counts 1,930 of them working in the state, 8.4 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.

Construction laborers (47-2061), 30% of the weighting: a median of $20.65 an hour, 9% below the US median of $22.66. The middle half of them earn between $17.64 and $23.62 an hour. About 19,620 work in the state. That is 85.1 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.

For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $23.53 an hour, which is 18% below the national $28.78. The middle half of them earn between $21.62 and $27.78 an hour. BLS counts 8,160 of them working in the state, 35.4 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.

For carpenters (47-2031, weighted 10%) the local median is $24.36 an hour, which is 16% below the national $29.12. The middle half of them earn between $20.97 and $30.10 an hour. BLS counts 6,950 of them working in the state, 30.2 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.

A crew paid at the 75th percentile for cement masons and concrete finishers ($29.70 an hour) would add about $170 to the statewide midpoint; one at the 25th percentile ($21.74) would take off about $60. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

BLS counts 2,305,080 jobs across South Carolina (May 2025), which is 1.5% of US employment.

Extras that change the South Carolina total

Extras are quoted nationally and then scaled to South Carolina by the average of the local wage index (0.87) and goods index (0.96), a factor of 0.92. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.
