Concrete costs in San Marcos, TX depend on the size of the job, the design, the finish, and the site work needed. A standard concrete driveway in most cases runs $7.50 to $11.50 per square foot. Decorative or stamped concrete can range from $12 to $22.50 per square foot or more. We give free on-site estimates. You get an accurate quote for your job before any work begins.
Most home concrete projects in San Marcos, TX take one to three days, depending on the size and scope of the job. Decorative or stamped finishes may need extra time for curing and sealing. Concrete in most cases reaches full strength within 28 days. But most surfaces are ready for light foot traffic within 24 to 48 hours after the pour.
Permit needs in San Marcos, TX depend on the type and size of your project. Driveways, retaining walls, and some structural work may need a building permit. The permit comes through the City of San Marcos Development Services Department. We guide you through the process and handle the paperwork. Your project moves forward without delays.
San Marcos, TX summers bring intense heat and UV exposure. Over time, that can crack or fade concrete. A quality sealer every two to three years protects your surfaces from moisture, staining, and thermal expansion. Keep expansion joints clear of debris. Then water drains off the slab instead of pooling on it. We offer sealing services and maintenance guidance to extend the life of your investment.

Concrete is priced by the square foot of the pour itself — length × width of the slab, driveway, or deck. Here are the ranges we see on real jobs around San Marcos, and a calculator built on the same numbers.
A standard two-car driveway is 20×20 ft — 400 sq ft — and at 4 inches with a plain broom finish it runs about $3,000–$4,600 around San Marcos. Six inches for RVs and work trucks, stamped or exposed finishes, and tearing out the old driveway each move the number up from there. Every price here includes the compacted base — Central Texas clay swells and shrinks with the weather, so the base has to be built right or the slab moves with it.
A 20×20 patio at 4 inches, broom finish, runs about $2,400–$4,400. Stamped and exposed-aggregate finishes are the popular upgrades here — they can add half again to the plain price. Six inches goes under hot tubs and outdoor kitchens.
A two-car garage slab, 24×24 ft at 4 inches, runs $3,744–$5,760. Foundation-grade work — 6 inches, thickened edge, rebar, vapor barrier — prices higher per foot and is the spec a house or addition actually needs.
Pool decks price like patios with three additions: coping edges at the water, drains that move splash water away, and a slip-resistant finish. A 400 sq ft deck runs about $2,600–$4,600 in a broom finish; cool-deck coatings and stamped finishes sit above that.
Small concrete work is priced by the visit more than the square foot. Replacing one cracked or heaved section runs $11–$19 per sq ft with the demo of that section included; resurfacing a sound slab runs $3.50–$6.50. If a section has sunk, heaved, or cracked clean through, resurfacing is paint on a problem — we'll say so at the look.
Where these numbers come from. Published Central Texas cost guides — Angi's Austin slab and driveway guides, HomeBlue's San Marcos slab guide, BuildX Pro's Austin driveway data, and Austin contractor pricing guides — gathered November 2026, on top of the national guides (HomeGuide, Angi, Fixr) behind the fleet concrete card. The full research note is on file with the site records.
A note on materials. These ranges figure a standard 4-inch pour of 3,500-psi concrete on a compacted base, broom finish. Decorative finishes — stamped, exposed aggregate, stained — add materials and skilled labor, and 6-inch work uses half again as much concrete on every square foot. Tell us what the slab has to carry and we'll confirm the spec and the exact price at the in-person estimate, before any work starts.
A standard 2-car driveway is 20×20 ft = 400 sq ft; 24×24 = 576.
Sections poured in one visit share a single minimum charge.
A 20×20 patio is 400 sq ft; 10×20 = 200.
Sections poured in one visit share a single minimum charge.
A 2-car garage is 24×24 ft = 576 sq ft; a house slab is often 1,200–2,000.
Foundation-grade includes a thickened perimeter edge, rebar, and a vapor barrier — that's the spec, not an upsell.
Measure the deck band around the pool — most home decks run 300–600 sq ft.
Sections poured in one visit share a single minimum charge.
Pool decks get a slip-resistant finish and slope away from the water — both are in these numbers.
For a section replacement, measure the section itself. For resurfacing, measure the whole surface.
Sections done in one visit share a single minimum charge.
Resurfacing only works on a slab that's still sound underneath. If a section has heaved, sunk, or cracked clean through, replacement is the honest fix — we'll tell you which one yours is at the in-person look.

A good mix, the right reinforcement, sealer, and a patient cure come standard on our jobs. They are not upsells. They are how a slab holds up for decades instead of failing in a few years.
We are a local crew serving San Marcos, not a traveling outfit. If a job fails early, we hear about it at the grocery store. So we build it to hold up, not just to look good at completion.
Stamped concrete copies the look of stone, brick, wood, or slate. It costs far less than the real material. It works well for patios, pool decks, walkways, and other concrete around the home.
We offer a range of decorative finish options, including:
Flatwork means any flat concrete surface poured at ground level. This includes driveways, sidewalks, patios, and garage floors — some of the most common San Marcos concrete services we complete.
Driveways
Residential and commercial vehicle access
Patios
Outdoor living and entertainment areas
Sidewalks
Pedestrian paths connecting structures
Garage slabs
Interior vehicle and storage floors
Commercial work needs heavier steel, higher PSI mixes, and tighter specs than most home jobs. We pour concrete for retail spaces, warehouses, office buildings, and rental properties across San Marcos.
Common commercial applications include:
We design each driveway around your layout, your drainage, and the loads it will carry. Our base work — grading and compaction done right — comes before any pour. That is the difference between a driveway that lasts for decades and one that cracks in a few years.
What we consider for every driveway project:
Concrete Patio Construction
We design concrete patios to match your yard's dimensions, your preferred finish, and how the space will actually be used. Whether you want a simple broom-finished slab or a decorative stamped surface with borders, we build it the way you want it.
Finish options available for patios:
Before any concrete is poured, we grade the site and set the forms. We place the vapor barrier and lay out the rebar. Each step affects how strong the finished foundation will be. Rushed base work is one of the most common causes of foundation failure.
Foundation types we pour:
Concrete slabs serve a wide range of purposes, from garage floors and workshop pads to basketball courts and gear bases.
Garage slab
Vehicle storage, workspace
Equipment pad
HVAC units, generators
Basketball slab
Recreational use
Storage shed base
Outbuildings
Commercial floor slab
Retail, warehouse, office
We press stamps and color hardeners into the concrete before it sets. The pattern goes right into the surface. The result is a finish with real texture and detail. It holds up under daily foot traffic and Texas weather.
Common stamped concrete patterns we install:
First, we look at the damage. Then we tell you if repair or full resurfacing is the right call. Surface cracks, spalling, and minor settling can often be fixed with resurfacing. A new layer bonds over the existing slab.
Signs your concrete may need repair:
We match each mix to the load and the use of the surface. A standard home driveway in most cases uses a 3,000–4,000 PSI mix. Heavier commercial work may need 4,000–5,000 PSI or higher.
We also apply:
We focus on clean forming and an even pour depth. We finish each surface with care. That is how our work holds up over time.
With stamped concrete, timing is key. The pattern must be pressed while the concrete is still soft, but not so early that it loses its shape.
Key techniques we apply:
Control joint cutting
Directs cracking to planned locations
Broom or trowel finishing
Controls surface texture and traction
Fiber reinforcement
Adds tensile strength to the mix
Gradual curing
Prevents surface cracking from rapid drying
Rushed base work is one of the most common causes of concrete failure. Before any pour, we grade and compact the sub-base, set forms at the correct elevation, and plan for drainage.
Drainage matters a lot in San Marcos. Hill Country terrain creates slope and runoff challenges. Water that pools under a slab will erode the base and cause settlement over time.
