What a commercial concrete project actually costs in San Antonio, broken down by project type, square footage, spec requirements, and the variables that move the price up or down. Real numbers from real jobs in Bexar County, not national averages that don't reflect the local market.
Commercial concrete pricing in San Antonio operates differently from residential work. The numbers are driven by scale, load requirements, permitting complexity, and the spec standards set by the City of San Antonio, TxDOT, and ADA compliance rules. A business owner or property developer budgeting for a commercial slab without understanding those variables will either overpay or underbuy, and both outcomes cost money.
This guide breaks down commercial concrete costs in San Antonio by project type: parking lots, warehouse floors, retail slabs, loading docks, and commercial driveways. It explains what drives the price, what the spec minimums are, and what questions to ask before any contractor begins work on your property.
Commercial concrete is not priced the same way as residential work. The spec is more demanding, the permitting is more involved, and the liability exposure on a commercial property is higher. A contractor quoting a commercial parking lot at residential pricing is almost certainly cutting corners on thickness, reinforcement, or base preparation. The cost tables in this guide reflect properly spec'd commercial work that will pass a City of San Antonio inspection, not the lowest number you can find.
A commercial concrete parking lot in San Antonio is one of the highest-volume projects we handle. The pricing range is wide because the variables are wide: lot size, expected traffic type, subgrade condition, drainage requirements, and whether the city requires a permit (it almost always does for new commercial paving).
The single biggest variable in commercial parking lot pricing is the existing subgrade. Bexar County's expansive clay soils require thorough excavation and a compacted crushed limestone base of at least 6–8 inches. When a low bidder skips this step, the slab will crack and heave within 3 to 5 years, long before the structural life of the concrete itself is exhausted.
How to get parking lot pricing that is actually comparable across bids: Require every bidder to specify in writing: slab thickness in inches, rebar size and spacing, base material and depth, joint spacing, and whether ADA compliance is included. Without that, you are comparing different products at different prices. The $5/sqft bid may be a 4" slab with wire mesh. The $7/sqft bid may be a 6" slab with proper rebar. They are not the same project.
- Slab thickness specified: 6" minimum for passenger vehicles, 8" for trucks and heavy equipment
- Reinforcement type and spacing in writing: #4 or #5 rebar at specified centers, not wire mesh alone
- Base preparation depth confirmed: minimum 6" compacted crushed limestone in Bexar County clay soils
- Control joint spacing noted: every 12–15 feet in both directions for a 6" commercial slab
- ADA compliance scope included if any accessible parking spaces are part of the project
- Permit coordination confirmed; commercial paving in San Antonio typically requires city permit
A warehouse or industrial concrete floor is a different product from a parking lot slab. The surface flatness tolerance, the concrete mix design, and the finish requirements are driven by the operations happening on the floor, not just the load it carries. A floor that racks and forklifts will roll across has to meet flatness standards (FF/FL numbers) that a parking lot never needs to worry about.
The vapor barrier is not optional for commercial warehouse floors in San Antonio. Even with our relatively dry climate, moisture migrating through the slab will damage floor coatings, rack anchors, and anything stored directly on the concrete. A 10-mil polyethylene vapor retarder under the slab is the minimum; 15-mil reinforced vapor barriers are standard for temperature-controlled storage facilities.
Ask for the design mix before approving a warehouse floor quote: A properly designed warehouse floor slab uses a minimum 4,000 PSI concrete mix, not the standard 3,000 PSI mix used for residential work. The w/c (water-to-cement) ratio should be 0.45 or lower to reduce shrinkage and improve surface hardness. Any contractor who cannot specify the mix design by PSI is not quoting a commercial-grade floor.
- Concrete mix design specified: minimum 4,000 PSI, w/c ratio 0.45 or lower
- Vapor barrier included: 10-mil minimum polyethylene under slab, 15-mil for temperature-controlled spaces
- Surface hardener specified if heavy forklift or rack anchor loading is expected
- Flatness tolerance (FF/FL number) defined in the contract if forklift operations will occur
- Saw-cut control joints scheduled within 4–8 hours of pour, before slab cracks on its own
- Cure time before forklift traffic confirmed: minimum 7 days for light traffic, 28 days for full loads
Commercial driveways and loading dock aprons are the hardest-working concrete on any commercial property. They carry fully loaded semi-trucks, suffer point loads from trailer landing gear, and absorb hydraulic fluid and diesel spills. No other surface on the property takes more abuse. The spec requirements reflect that, and the cost reflects the spec.
Loading dock aprons require special attention to joint design. The transition between the apron and the adjacent pavement is where reflective cracking and joint deterioration start. Doweled construction joints with load transfer bars, armored joint edges, and a proper sealant system extend the life of the dock apron by 10–15 years compared to a standard butt joint.
Any commercial driveway approach connecting to a public street in San Antonio requires a City of San Antonio Right-of-Way Construction Permit. If the approach connects to a TxDOT-maintained roadway (a state highway or US route), a TxDOT Driveway Permit is required separately. These are not optional, and unpermitted work in the right-of-way can result in mandatory removal at the property owner's expense.
- Slab thickness specified for the actual expected load: 8" minimum for semi-truck traffic
- Rebar size and spacing confirmed: #5 at 12" centers as a minimum for heavy commercial approaches
- Slope direction designed and confirmed in writing: 1–2% away from the building
- Doweled joints with load transfer bars specified at all construction joint locations
- Right-of-way permit obtained before any work begins at the street connection
- TxDOT permit confirmed if the approach connects to a state or US highway
Concrete work for retail centers, restaurants, and office properties in San Antonio involves a different set of priorities than industrial work. Aesthetic finish matters in customer-facing areas. ADA compliance requirements are stricter because members of the public are using the space. And the timeline pressure is higher: a retail tenant cannot open until the concrete passes inspection.
| Application | Spec | Cost range (San Antonio) | Key considerations |
|---|---|---|---|
| Retail storefront sidewalk and apron | 4–5" slab, broom finish, ADA-compliant slope | $7–11/sqft | Must meet City of San Antonio sidewalk standards and ADA cross-slope requirements (max 2%) |
| Restaurant patio (covered or uncovered) | 4" slab, decorative finish, slope for drainage | $10–20/sqft | Stamped or stained finish common; grease trap access and floor drain locations must be set before pour |
| Office building exterior walkways | 4" slab, broom finish, accessible route | $7–12/sqft | Accessible route from parking to building entrance must be continuous. ADA requires no change in level greater than 1/4" without a bevel |
| Retail strip center parking lot | 6" slab, rebar, ADA spaces + accessible aisles | $6–10/sqft | Accessible parking space count is determined by total lot size per ADA standards; Van-accessible spaces require 8-foot access aisle minimum |
| Drive-through lane (restaurant / bank) | 6–7" slab, #4 rebar, sealed joints | $9–14/sqft | Constant turning radius creates stress concentrations at edges; expansion joints and edge restraint are critical |
| Concrete retaining wall (commercial) | Engineered design required by city | $40–80/sqft of wall face | Any retaining wall over 4 feet in San Antonio requires a stamped engineering drawing and Building Permit |
Build concrete cure time into your tenant opening schedule: The most common construction delay for retail and restaurant openings in San Antonio is concrete that is not fully cured before floor coverings, equipment, or heavy fixtures are installed. A concrete slab needs 28 days to reach full structural strength. You can walk on it in 48 hours and do light work in 7 days, but setting commercial kitchen equipment or rolling shelving into place at day 10 on a new slab risks surface damage and long-term strength issues. Build 28 days of cure time into your project timeline before the trades go back in.
Commercial concrete quotes in San Antonio can vary by 30–50% for what appears to be the same project. That range is not arbitrary. It reflects real differences in what the contractor is including and what they are leaving out.
| Variable | Impact on price | What to know |
|---|---|---|
| Project size (square footage) | Larger = lower per sqft cost | Concrete is a volume business. A 50,000 sqft parking lot costs significantly less per square foot than a 5,000 sqft lot; mobilization costs and concrete delivery efficiency scale with size |
| Existing site conditions | Demolition, excavation, and haul-off add $1–3/sqft | Removing existing asphalt or deteriorated concrete adds cost. Rocky subgrade or poor compaction may require deeper excavation than originally estimated |
| Subgrade quality | Can add $1–4/sqft if lime stabilization is needed | San Antonio's high-plasticity clay soils sometimes require lime treatment before a commercial base can be placed. This is identified in the geotechnical report. Do not skip the geotech on large commercial pours |
| Concrete mix design (PSI) | 3,000 PSI vs. 4,500 PSI adds $0.50–1.50/sqft | Commercial projects should specify minimum 4,000 PSI. Higher-strength mixes cost more at the batch plant but reduce long-term maintenance costs significantly |
| Reinforcement type | Fiber-reinforced adds $0.30–0.60/sqft; heavy rebar grids add $1–2/sqft | Wire mesh is the cheapest reinforcement option and the least effective in high-load commercial applications. Specify rebar size and spacing explicitly in your contract |
| Season and weather | Summer pours may add scheduling premium | Concrete work in San Antonio's peak summer heat requires early morning starts, curing compounds, and more labor oversight. Experienced contractors price this in; inexperienced ones skip the precautions and charge the same rate |
| Permitting complexity | Permit fees range from $500 to $5,000+ depending on project scope | Commercial projects in San Antonio almost always require permits. Permit fees, plan review time, and inspection scheduling should be factored into project timelines and cost |
| Access and site constraints | Tight access for concrete trucks adds $0.50–2/sqft | Concrete trucks need reasonable access to pour efficiently. Sites that require concrete pumping (because trucks cannot get close enough) will add pump rental and operator costs |
| Specialty finishes | Decorative work adds $3–12/sqft over standard broom | Exposed aggregate, staining, or stamped patterns in exterior commercial areas add both material and labor cost but can significantly improve the appearance and property value of retail and hospitality projects |
Bexar County soils are not uniform. High-plasticity clay (PI above 30) is common in many parts of San Antonio and can require lime or cement stabilization before a commercial base can be placed. A geotechnical report costs $800–2,500 for a typical commercial site and tells you exactly what the subgrade conditions are. Without it, your contractor is guessing, and if the subgrade fails after the pour, no contractor warranty covers it. The geotech report is the cheapest insurance you can buy on a commercial concrete project.
Not every concrete contractor in San Antonio is equipped for commercial work. Commercial projects require different insurance levels, permit experience, equipment capacity, and familiarity with city and county code requirements. Hiring a residential driveway crew for a commercial parking lot or warehouse floor is one of the most common and expensive mistakes property owners and developers make.
| What to verify | What a qualified commercial contractor provides | Red flag |
|---|---|---|
| General liability insurance | $2M+ general liability; commercial projects require higher coverage than residential | Certificate of insurance below $1M, or no documentation provided |
| Workers' compensation | Active workers' comp policy covering all crew members | "We use subcontractors" as a reason not to carry workers' comp. This puts you at risk |
| Permit experience | Has pulled commercial concrete permits in Bexar County recently and can name the permit types required for your project | Does not mention permits or asks you to handle permitting yourself |
| Written quote detail | Itemizes slab thickness, mix design PSI, rebar spec, base depth, joint spacing, finish type, and cleanup separately | Quote is one line: "concrete parking lot, 10,000 sqft, $X" |
| Mix design specification | States the concrete PSI, aggregate size, and w/c ratio, or refers to a specific ACI mix design | Cannot specify PSI or says "we use standard concrete" |
| Commercial portfolio | Photos and addresses of comparable completed projects in San Antonio | Only residential projects in their portfolio, or stock photos with no verifiable local work |
| Payment terms | Deposit (25–40%) to mobilize, progress billing on large projects, final payment after punch list approval | Full payment required before work begins, or no written payment schedule |
