The cost to pour an 8×10 concrete slab typically ranges from about $320 to $1,200 before tax, depending on thickness, reinforcement, site prep, and finishing. Key drivers include subgrade preparation, forms, concrete strength, and whether any additional features are needed. Understanding these factors helps buyers estimate total project pricing.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|

| Labor | $280 | $420 | $750 | Pour, finish, joints; 1–2 workers, 3–6 hours |
| Equipment | $80 | $120 | $200 | Forms, vibrator, saw cut |
| Delivery/Disposal | $40 | $70 | $100 | Truck delivery and waste removal |
| Permits/Inspections | $0 | $50 | $100 | Depends on local rules |
| Overhead/Contingency | $0 | $40 | $80 | 10–15% of subtotal |
Overview Of Costs
Typical range for an 8×10 slab is $320-$1,200, with per-square-foot costs commonly cited between $4 and $15 depending on reinforcement and site prep. The lower end reflects basic 4-inch pours with standard gray concrete on a prepared surface, while the higher end includes thick slabs, reinforced wire or rebar, and extra finishes. Assumptions: region, slab thickness, and basic site prep.

| Delivery/Disposal | $40 | $70 | $100 | Transport and waste |
| Overhead & Contingency | $0 | $40 | $80 | Budget cushion |
What Drives Price
Site prep and slab thickness are primary cost drivers. A 4-inch slab on-grade is the baseline; increasing thickness to 6–8 inches for load or equipment support adds material and labor. Concrete strength (e.g., 3,000 psi vs. 4,000 psi) affects material cost. Subgrade moisture control, forms, joints, and reinforcement (wire mesh or rebar) also push costs higher. Assumptions: standard residential site, no structural engineering required.
Ways To Save
Careful planning can reduce surprises and overruns. Consolidate deliveries, reuse existing forms when feasible, and schedule during off-peak seasons in regions with price variance. Request a single, itemized quote to compare exact line items and avoid hidden fees. Assumptions: basic finishes, standard delivery window.
Regional Price Differences
Prices vary by region due to labor and material availability. In coastal metro areas, expect higher labor costs and delivery charges; in rural areas, savings may come from lower permit and disposal fees, but access limitations can add time. For a typical 8×10 slab, regional deltas can be ±15% to ±30% from the national average. Assumptions: three representative markets.
Labor, Hours & Rates
Labor costs combine crew size and time estimates. A two-person crew often completes a basic 8×10 pour in 3–6 hours, including finishing and jointing. Hourly rates can range from $35 to $85 per hour per worker, depending on region and demand. Assumptions: standard crew and local wage norms.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes.
Basic — 4-inch slab, no reinforcement beyond standard mesh, standard finish. Specs: 8×10, 80 sq ft, 1.0 yd³, 2 workers, 3 hours. Total: $350-$520. Assumptions: simple site, standard mix.
Mid-Range — 4-inch slab with welded wire mesh, basic broom finish. Specs: 8×10, 1.5 yds, 2–3 workers, 4–5 hours. Total: $680-$980. Assumptions: moderate finish, average regional costs.
Premium — 6-inch slab or 8-inch with rebar, decorative finish, improved subgrade. Specs: 8×10, 2.0–2.5 yds, 3–4 workers, 6–8 hours. Total: $1,000-$1,200+. Assumptions: higher strength concrete, reinforcement, and finish work.
