Having a contractor pour concrete typically costs $6-$12 per square foot for a basic, professionally installed slab, with small jobs and decorative finishes costing more. Total price depends on slab size and thickness, site preparation, concrete strength, access for delivery, reinforcement, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed basic slab | $6 per sq ft | $9 per sq ft | $12 per sq ft | Standard access and broom finish |
| 400-sq-ft patio | $2,400 | $3,600 | $4,800 | About 4 inches thick, no major demolition |
| Concrete material | $125 per cu yd | $160 per cu yd | $200 per cu yd | Delivery and local surcharges may be extra |
| Small-job minimum | $500 | $900 | $1,500 | Varies with travel, setup, and truck access |
What a standard concrete pour costs by slab size
A basic slab usually costs $6-$12 per square foot installed, while a small pour can have a higher effective rate. That range generally covers ordinary ready-mix concrete, forming, placement, finishing, and a simple broom texture. It assumes a level or moderately prepared site, normal truck access, and a residential job using common concrete strength.
A 10-by-10-foot pad may cost $800-$1,500 even though its area is only 100 square feet; contractor minimums and mobilization can outweigh the square-foot rate. A 400-square-foot patio commonly lands around $2,400-$4,800. A 600-square-foot driveway may run $4,800-$9,000 for a standard design, with thicker concrete or extensive base work increasing the estimate.
Concrete volume also provides a useful cross-check. A 4-inch slab takes about 0.0123 cubic yards per square foot, so 400 square feet requires roughly 4.9 cubic yards before waste. Contractors often order a little extra to account for uneven ground and spillage. Material alone is only part of the bill; labor, forming, equipment, and site preparation make up much of an installed quote.
Assumptions: Typical U.S. residential pricing, standard ready-mix, 4-inch slab, basic finish, and no unusual access or drainage work.
How concrete, labor, and forming appear in a quote
Installed pricing is a combination of materials and job work, not just the ready-mix truck charge. The breakdown below represents a typical 400-square-foot, 4-inch slab with a basic finish. Actual estimates may combine several rows into a single square-foot price, and regional labor or minimum charges can shift the shares.
| Quote component | Typical rate | 400-sq-ft example | What it covers |
|---|---|---|---|
| Ready-mix concrete | $125-$200 per cu yd | $650-$1,100 | About 5-5.5 cu yd, including waste allowance |
| Labor and finishing | $2-$5 per sq ft | $800-$2,000 | Placement, screeding, edging, and surface finish |
| Forms and reinforcement | $1-$3 per sq ft | $400-$1,200 | Form boards, stakes, mesh, or rebar as specified |
| Base and site preparation | $1-$4 per sq ft | $400-$1,600 | Grading, compacted gravel, and minor excavation |
| Equipment and delivery | $150-$800 per job | $150-$800 | Truck access, pump, tools, and delivery charges |
| Disposal or haul-away | $100-$1,000 per job | $100-$1,000 | Old slab or excess soil removal when required |
These components are not always additive at their maximums: a contractor may include forms or routine equipment in the installed rate. Pumping can add roughly $500-$1,500 when a truck cannot discharge close to the forms. Reinforcing steel, thicker sections, and a substantial gravel base should be listed clearly so the buyer can compare equivalent scopes.
Labor estimates can be checked with . Crew rates vary, but labor may effectively work out to about $50-$100 per worker-hour after payroll burden, tools, and business overhead. A quote that lists only a low material cost is not comparable to one that includes placement, finishing, and cleanup.
Why thickness, access, and finish change the estimate
Thickness and access are two of the quickest ways for a concrete quote to move beyond the basic range. A 4-inch slab is common for patios and light-duty residential use; a driveway intended for vehicles may need 5-6 inches or a design suited to soil and expected loads. Moving from 4 to 6 inches increases concrete volume by 50%, before any added reinforcement or labor.
Size affects price in two directions. Larger pours usually reduce the per-square-foot cost because setup is spread over more area, but they require more concrete and may need a larger crew. Below about 200 square feet, minimum charges are especially common. A pour requiring less than a full truckload may also face a short-load fee, often $100-$300 depending on supplier and market.
Site access matters when the truck cannot reach the forms. A pump may add $500-$1,500, while wheelbarrow placement over a long route can add labor. Slopes, soft soil, roots, buried utilities, or drainage corrections can require excavation and additional base material. Excavation and grading may add $2-$8 per square foot where conditions are difficult.
Finish and reinforcement change both material and labor. A broom finish is usually among the least expensive choices; exposed aggregate or stamped patterns can add about $3-$10 per square foot, and colored concrete can add $1-$4 per square foot. Wire mesh may add $0.20-$0.60 per square foot, while rebar, thicker edges, or engineered reinforcement costs more. The written scope should state the thickness, strength, reinforcement, and finish.
How to lower the concrete bill without cutting essentials
Keeping the design simple and the site ready often saves more than choosing a cheaper concrete mix. A rectangular layout uses forms efficiently and is easier to finish than a design with many curves, corners, or steps. Combining nearby small pours into one scheduled project may reduce separate mobilization or minimum charges, if the work can be completed under suitable weather and access conditions.
Ask whether the quoted area includes excavation, gravel, reinforcement, control joints, and cleanup. Then compare at least three written estimates with the same dimensions and specifications. A lower bid may omit removal, grading, or a pump that another contractor has included. Request a line-item explanation of extra charges for short loads, delivery, disposal, and site complications.
Choose a finish that suits the use rather than adding decorative work by default. Broom-finished concrete can be durable and slip-resistant for many patios and walkways; stamping, staining, and exposed aggregate add labor and material expense. Avoid reducing thickness or reinforcement solely to lower a price: the required design depends on use, soil, climate, and local requirements.
Basic preparation can help when the contractor approves it. Clearing furniture, plants, or loose debris may prevent billed prep time, but excavation, grading, and compaction should be performed by someone capable of meeting the project specification. Poor base preparation can lead to settlement or cracking and costly repairs. Schedule flexibility can also help contractors coordinate a pour, but weather conditions and curing needs should take priority over a rushed date.
How long crews need for a residential slab pour
Most straightforward residential pours take one or two days of crew work, although preparation and curing extend the overall timeline. A small pad may require several hours for forming, placement, and finishing once the base is ready. A typical 400-square-foot patio can need a crew of three to five workers for roughly 6-10 hours on pour day, plus a separate visit for layout or preparation.
Labor time depends on slab geometry, truck access, weather, and the finish. A pump can reduce difficult carrying but has its own setup and minimum charge. Decorative stamping requires coordinated work during a limited finishing window and often costs more because of specialized labor. Rain, high heat, or freezing conditions can delay the pour or require protection and curing measures.
Concrete may be walkable after about 24-48 hours, depending on conditions and mix, but heavy loads should not be placed on it immediately. Driveways commonly need several days before vehicle traffic, and full design strength is typically reached over a longer curing period. The contractor should provide project-specific access and curing instructions; curing time is not the same as crew labor time.
Three example quotes for patios, pads, and driveways
These examples show how area, preparation, and access produce different totals at similar base rates. They are illustrative U.S. estimates, not fixed national prices. Each assumes ordinary residential labor, a basic finish, and no major permit or drainage expense.
| Project | Scope and unit rate | Labor and equipment | Estimated total |
|---|---|---|---|
| Small AC pad | 8-by-10 feet, 4 inches; $10-$15 per sq ft effective | 2-3 workers, 4-6 hours; basic form and delivery | $800-$1,200 |
| Backyard patio | 400 sq ft, 4 inches; $7-$12 per sq ft | 3-5 workers, 6-10 hours; modest gravel base | $2,800-$4,800 |
| Two-car driveway | 600 sq ft, 5 inches; $9-$15 per sq ft | 4-6 workers, 8-12 hours; stronger base and reinforcement | $5,400-$9,000 |
The small pad has a higher unit price because contractor setup, dispatch, and delivery are spread over little area. The driveway assumes ordinary access and a mostly prepared site; demolition, a steep slope, or a pump could push it above the range. If a contractor proposes a materially lower total, confirm whether the quote includes the required thickness and base, rather than comparing totals alone.
What demolition, pumping, and permits add to a pour
Extra charges are often tied to access or work that happens before the new concrete arrives. Removing an existing slab commonly costs about $2-$6 per square foot, including breaking and hauling, although thick or reinforced concrete can cost more. Soil excavation and disposal may be priced by volume or equipment time; ask whether the quote includes a haul-away fee and a tipping charge.
A concrete pump is useful when the truck cannot discharge near the forms, but it is not automatically necessary. Typical residential pump charges fall around $500-$1,500, depending on equipment, distance, and minimum run time. Difficult hand placement can also add labor. Short-load fees, weekend delivery, and remote delivery may be separate supplier charges, so the estimate should identify them before work begins.
Permit rules depend on the city, county, and project. A simple patio may not need a permit in some locations, while driveway changes, work near public sidewalks, drainage changes, or structures may require approval or inspection. Permit fees often range from about $50-$500 for straightforward residential work, but requirements and charges vary substantially. Confirm local rules before scheduling, and ask whether the contractor has included permit handling.
Some jobs also need drainage adjustments, utility locating, or changes to meet local code. These should be treated as distinct scope items, not assumed to be included in a per-square-foot slab rate. A written quote should describe what happens if excavation uncovers unsuitable soil or buried obstacles, along with how added work will be priced.
How concrete prices differ across U.S. markets
Local labor, delivery distance, and concrete supply can shift an otherwise identical job by roughly 10%-30%. Large metropolitan areas and high-cost coastal markets may run about 10%-25% above a national middle-market estimate, particularly where labor is tight or site access is limited. Smaller towns can be 5%-15% below some metro prices, but remote delivery or a distant batch plant may erase the difference.
Weather also affects scheduling and job requirements. Freeze-thaw regions may need attention to drainage, air-entrained concrete, and a suitable base, while very hot conditions can require additional timing or curing precautions. These are design and construction considerations, not optional upgrades to eliminate without advice. Ask local contractors to identify the concrete mix and preparation they recommend for the site and expected use.
Supplier quotes may include fuel, environmental, or short-load surcharges that differ by market. Comparing two quotes from contractors serving the same area is more useful than applying a national average to a specific property. The most meaningful comparison uses the same slab dimensions, thickness, concrete strength, reinforcement, finish, access plan, and cleanup scope.
Assumptions: Price ranges are broad residential estimates; local codes, soil, weather, and contractor availability can change the final bid.
