What does commercial concrete actually cost in San Antonio? This complete guide breaks down pricing by project type, explains every factor that shifts your number up or down, and shows you how to get an accurate bid from a qualified local contractor.
Commercial concrete is not priced the same way as a residential patio. When a business owner or property manager in San Antonio requests a quote for a parking lot, warehouse floor, restaurant slab, or retail pad, the numbers coming back can range from $6 per square foot to $30 per square foot or more and both figures can be completely accurate, depending on what the project actually requires.
The goal of this guide is to help you understand what drives that range, what questions to ask before accepting a bid, and what the realistic cost is for the most common commercial concrete projects in San Antonio. Every number in this guide reflects current local market conditions in 2026.
A 10,000 sqft warehouse floor poured at 6″ with rebar, vapor barrier, and polished finish costs roughly three times more per square foot than a basic 10,000 sqft parking lot slab at 4″ with wire mesh. The square footage is identical but the scope is completely different. Before you compare quotes, make sure every bidder is working from the same written specification. If they are not, you are not comparing prices you are comparing different projects.
Exterior Work
A concrete parking lot is the most commonly quoted commercial concrete project in San Antonio. Costs depend on slab thickness, reinforcement type, sub-base preparation, and site conditions. For a standard commercial parking lot with no unusual conditions, expect:
San Antonio’s expansive clay soils make base preparation especially critical for parking lots. A contractor who quotes low but skips proper compaction and crushed limestone base is setting up the slab for premature cracking. Require that every bid itemize base work separately so you can compare it across contractors.
- Sub-base depth and material specified minimum 6″ compacted crushed limestone
- Slab thickness confirmed in writing 5″ minimum for standard commercial traffic
- Reinforcement type and spacing listed rebar grid preferred over wire mesh on clay soils
- Expansion joint spacing stated every 15–20 feet for large commercial pours
- Concrete mix design included 4,000 PSI minimum for commercial applications
Industrial
Warehouse and industrial floors have the most demanding performance requirements of any commercial concrete work. Forklifts, heavy racking, and point loads require thicker slabs with higher PSI mixes and often polished or sealed finishes to control dust. The flatness spec (measured by the F-number system) also increases cost.
Cold storage and refrigerated distribution facilities require additional moisture control and insulation beneath the slab, which can add $4–8 per square foot. If racking systems will apply point loads over 20,000 lbs, the structural engineer should specify the slab do not let the concrete contractor make that call without the engineering documentation to support it.
For any warehouse floor that will use forklifts, request an FF/FL (flatness/levelness) floor tolerance specification from your engineer. A floor poured without a flatness spec can be legally within normal tolerances and still cause forklift mast sway and racking problems. Most logistics operations want FF35/FL25 minimum.
Food Service
Restaurant concrete has specific code requirements that drive cost well above a standard commercial slab. Kitchen floors must slope precisely to floor drains, grease trap surrounds require chemical-resistant concrete or coatings, and the City of San Antonio requires specific finishes in health-inspected areas. Skipping any of these details creates compliance problems during inspections.
Drive-through lanes deserve special attention in San Antonio’s climate. The combination of heat, vehicle weight, and constant stop-and-go traffic causes faster wear than a standard parking lot. A 6″ slab with 4,500 PSI mix and rebar grid is the minimum spec for a drive-through lane not the 4″ light-duty slab some contractors will propose to win the bid on price.
Retail / Office
Retail and office concrete spans the broadest range because it includes both interior floor slabs and exterior pads, sidewalks, ADA ramps, and parking areas. The interior slab for a retail space is typically 4″ on grade with wire mesh relatively straightforward. The exterior work around the building is where costs escalate, especially when curb, gutter, ADA-compliant ramps, and detention pond connections are included in scope.
Medical office buildings have additional requirements around vibration control and load-bearing capacity for imaging equipment. MRI and CT equipment can weigh 15,000–30,000 lbs and require engineered slab specifications that go well beyond standard commercial flatwork. If your project involves any medical imaging installation, get a structural engineer’s slab specification before soliciting concrete bids.
Repair / Overlay

Not every deteriorating commercial slab needs full replacement. When the base is structurally sound and the surface damage is limited to the top 1–2 inches, a concrete overlay or resurfacing treatment can extend the life of the slab by 10–20 years at a fraction of replacement cost. The key question is always whether the underlying slab has structural integrity if it does not, an overlay is wasted money.
A qualified contractor should perform a core test or ground-penetrating radar scan on any slab being considered for overlay before proposing the repair approach. In San Antonio’s clay-heavy soil environment, slab voids from soil settlement are common and are not visible from the surface. Overlaying a slab with sub-slab voids produces a hollow, cracking surface within 12–18 months.
Ask for a repair vs. replacement analysis in writing before accepting either recommendation. Any contractor who recommends full replacement without assessing the base condition or recommends overlay without a ground scan is not giving you a complete picture. Both calls require site investigation to make responsibly.
Two commercial concrete projects in San Antonio can look identical on paper and come in with prices that are $8 per square foot apart. Understanding the six variables that drive that difference helps you read a bid critically and spot the places where contractors cut corners to lower their number.
The table below reflects current market pricing for commercial concrete work in San Antonio and surrounding Bexar County. All figures assume proper sub-base preparation, standard commercial reinforcement, and 4,000 PSI concrete unless otherwise noted. Pricing excludes demolition of existing concrete, disposal fees, and permits unless specified.

The most common reason commercial concrete projects go over budget is not that the original bid was wrong it is that the original bid was incomplete. When a specification is vague, contractors fill in the blanks with whatever number wins the job, not whatever scope protects the owner. Here is how to close that gap before you sign anything.
Send every bidder the same document. It should include the square footage, intended use of the slab, required slab thickness, concrete PSI requirement, reinforcement type, sub-base specification, finish type, and any code or permit requirements you are already aware of. Contractors who refuse to bid from a written scope are telling you something important about how they operate.
A single number for “complete concrete work” tells you almost nothing. Require that every bid separate: site preparation and base work, concrete materials (mix design and volume), reinforcement materials (rebar or mesh), pour and finishing labor, expansion joint installation, cleanup and disposal, and any specialty items like vapor barrier or epoxy coating. When you line up three bids side by side in this format, the differences become immediately visible.
Not every concrete contractor who does excellent residential work is set up for commercial projects. Commercial work requires different insurance minimums (typically $2M+ general liability), the ability to bond larger projects, familiarity with City of San Antonio commercial permit requirements, and experience working alongside general contractors and structural engineers. Ask specifically about commercial references from the past two years in San Antonio.
If a commercial concrete bid does not include a specific concrete mix design (PSI, water-cement ratio, air entrainment), that contractor is planning to order whatever their ready-mix supplier delivers that day. Mix design matters enormously for durability in San Antonio’s heat a low water-to-cement ratio (0.45 or below) is essential for long-term strength. If it is not in the bid, ask for it in writing before you award the contract.
Commercial concrete work in San Antonio almost always requires permits from the City of San Antonio Development Services Department. Parking lots, site work, floor slabs in new construction, and any work in a public right-of-way all need permits. Some contractors include permit management in their scope; others do not. Get clarity on who is responsible for pulling permits, scheduling inspections, and providing the paperwork trail before work begins.
