Concrete cost per foot usually means price per square foot and ranges from $6 to $18 for a professionally installed slab, depending on thickness, finish, access, and location. A basic 4-inch slab averages about $8-$10 per square foot; decorative finishes, reinforcement, demolition, or difficult site access can raise the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic poured concrete | $6/sq ft | $8-$10/sq ft | $12/sq ft | Standard 4-inch slab and broom finish |
| Concrete patio | $1,200 | $2,400 | $4,500 | About 200-300 sq ft, before unusual site work |
| Concrete driveway | $3,000 | $6,000 | $12,000 | About 400-800 sq ft; thickness and removal matter |
| Stamped or colored concrete | $10/sq ft | $14-$18/sq ft | $25/sq ft | Pattern, color, and sealer affect pricing |
What a 4-inch concrete slab costs per square foot
For a simple, accessible 4-inch slab with a standard broom finish, installed prices commonly run $6-$12 per square foot, with $8-$10 a practical planning average. A 400-square-foot slab may therefore cost about $2,400-$4,800, excluding major grading, demolition, or drainage work. Small projects can have a higher per-foot rate because crew mobilization and minimum charges are spread across fewer square feet.
These figures generally include concrete, basic forming, placement, and finishing. They assume ordinary ready-mix, a reasonably level site, and typical local labor rates; they do not guarantee a contractor quote. Assumptions: standard materials, normal access, no major excavation, and a basic finish. For a straightforward 4-inch pour, budgeting roughly $8-$10 per square foot is a useful starting point.
How concrete, labor, and site work appear on a quote
Contractors may present a single installed price or separate the work into materials, labor, and preparation. The breakdown below is a general allocation for a standard residential slab; local bids can group these charges differently.
| Quote item | Typical price | What changes it |
|---|---|---|
| Concrete materials | $2-$5/sq ft | Thickness, mix strength, delivery distance |
| Labor and finishing | $3-$7/sq ft | Crew size, finish, pour complexity |
| Base, forms, and reinforcement | $1-$4/sq ft | Gravel depth, rebar or mesh, form layout |
| Equipment and delivery | $150-$700 total | Truck access, pump needs, small-load fees |
| Removal and disposal | $2-$6/sq ft | Old slab thickness and hauling distance |
Labor may be estimated by area or by crew hours. A pump, where required to reach a backyard or elevated pour, can add roughly $500-$1,500. Ask whether the written quote includes excavation, base compaction, reinforcement, delivery, and cleanup.
Thickness, reinforcement, and finish change the square-foot rate
Thickness is a major concrete cost driver because deeper slabs use more material and may require additional preparation. A 4-inch slab is common for patios and many walkways; a 6-inch slab can be appropriate for heavier vehicle loads, subject to site conditions and local specifications. Moving from 4 to 6 inches can add about $1-$3 per square foot.
Rebar or wire mesh may add roughly $0.50-$2 per square foot, while stamped patterns and integral color can push finished pricing into the $10-$25 range. Slopes, poor soil, drainage corrections, and limited truck access also increase labor or equipment needs. Confirm the specified thickness and reinforcement before comparing bids, since a cheaper quote may cover a lighter-duty slab.
Concrete prices in urban, suburban, and rural markets
Labor rates, ready-mix availability, permitting, and delivery distance create regional differences. Urban projects often run about 10%-25% above a comparable suburban job because of higher labor costs, access restrictions, parking, or pumping. Rural work may be 5%-20% higher when the site is far from a batch plant or a small pour triggers a delivery minimum.
These are broad comparisons, not fixed regional price lists. Local demand and weather can outweigh the urban-rural pattern, and a remote site with easy truck access may cost less than a crowded city lot. Use local bids with matching slab dimensions and scope rather than relying on a national per-foot average alone.
How long a residential concrete pour takes
A typical crew of three to five workers may spend one to two days preparing and pouring a 400-800-square-foot slab, with additional time for excavation or demolition. The concrete is usually placed and finished in hours, but scheduling depends on weather, crew availability, and ready-mix delivery. Labor rates commonly fall around $50-$100 per worker-hour when priced separately, though many contractors quote a project total.
Concrete needs time to cure before it reaches its intended strength. Walking may be allowed after about 24-48 hours, while vehicle use commonly requires at least seven days and sometimes longer under the contractor’s instructions. Schedule curing time into the project plan; rushing the pour or reopening a driveway early can lead to expensive damage.
Three sample patio and driveway estimates
These examples illustrate how area, finish, and site work affect totals. Each assumes ordinary access and local midrange pricing; actual quotes vary by market and specifications.
| Project | Calculation | Estimated total |
|---|---|---|
| Basic patio | 240 sq ft × $9/sq ft | $2,160 |
| Reinforced driveway | 600 sq ft × $12/sq ft, including 6-inch thickness | $7,200 |
| Stamped patio | 300 sq ft × $17/sq ft | $5,100 |
A quote for a larger driveway may also include removal of existing concrete, grading, or a pump fee, so its total can exceed the per-foot calculation. Compare the listed scope and finish as well as the final dollar amount.
When replacing concrete beats patching a cracked slab
Small, stable surface cracks may be repairable for about $300-$800, while larger crack repairs or leveling commonly cost $500-$2,500 depending on area and method. Replacement becomes more likely when the slab has widespread settlement, broken sections, poor drainage, or repeated damage. New concrete often costs $6-$12 per square foot for a basic pour, with demolition and disposal adding approximately $2-$6 per square foot.
Repairs can cost less upfront but may not address a failing base or recurring water problem. A contractor should identify whether the issue is surface-level or structural before pricing a patch. Compare the repair cost with a replacement quote that includes removal, base work, and the same finished area.
Lower the concrete bill by controlling scope and access
Keeping the slab dimensions simple, preparing a clear route for trucks, and arranging removal before pour day can reduce labor delays. A standard broom finish usually costs less than stamping, exposed aggregate, or custom borders. Combining nearby pours may also reduce repeated delivery or crew mobilization charges, if both areas are ready at the same time.
Request at least three itemized quotes using identical dimensions, thickness, reinforcement, finish, and site-preparation requirements. Check whether small-load fees, permits, disposal, and taxes are included, and avoid paying for upgrades that do not suit the slab’s use. Matching the scope across bids is the most reliable way to tell whether a lower price is a real saving.
