Concrete & flatwork cost estimator

Draw or size your area, pick a quality tier, and watch an honest, line-item price range build as you go — driveways, patios, sidewalks, slabs and commercial & industrial floors across the San Antonio–Austin I-35 corridor. It’s a budget range, not a final quote: a free on-site measure confirms the firm number.

How the concrete estimate is built

Most online concrete calculators just multiply square feet by one rate. Ours doesn’t. It builds the price the way a real estimator does — from concrete cubic yards (area × thickness, plus a waste factor), a compacted base, the reinforcement you choose (fiber mesh through #5 rebar), labor, finishes like broom, stamped or stained, plus demolition, drainage, permits and engineering where they apply.

On top of that it applies transparent site-complexity multipliers for access, shape, load and slope, then shows a low–expected–high range with a confidence level. Every figure is a line you can see, so you understand exactly why a 4″ patio and a 6″ commercial driveway aren’t priced the same.

It’s a budget range, not a contract. We confirm the firm price with a free on-site measure that checks subgrade, base and drainage — and we’ll tell you plainly when a slab needs an engineer or a city permit. Prefer to read first? See the full concrete & flatwork services.

Concrete cost questions

How much does concrete cost per square foot in Texas?+
Installed flatwork in the San Antonio–Austin corridor generally runs about $8–$18 per square foot for standard residential work, and $16–$40+ for decorative or commercial-grade slabs. The estimator builds a line-item range from your real measurements, thickness, base, reinforcement and finish.
Is the estimate a final quote?+
No — it’s a budget range based on the numbers you enter. We confirm the firm price with a free on-site measure that checks your subgrade, base, drainage and access before any contract.
What changes the price of a concrete slab?+
Thickness, PSI, reinforcement, base depth, finish, demolition and haul-off, drainage correction, access difficulty, permits and engineering. The estimator shows each as its own line so you can see why the price moves.
How accurate is the concrete estimator?+
It uses the same line-item logic our estimators use, so the range is realistic. Final pricing can still shift with hidden conditions like soft soil, demolition thickness or utility conflicts.
Does it estimate commercial & industrial concrete too?+
Yes — pick a commercial or industrial project type for thicker, heavily reinforced slabs with load-transfer joints, and the estimator flags where an engineer, permit or ADA review is typically required.
