Custom Concrete in San Antonio, TX
San Marcos Custom Concrete builds and finishes custom concrete in San Antonio, TX. We serve homes and businesses across the city. We handle everything from stamped patios to structural business slabs. We serve builders, property managers, and homeowners who need strong flatwork. They need decorative finishes and driveway work done right the first time. Our crews bring years of hands-on work. We pour, stamp, stain, and seal concrete across Bexar County. We back each project with licensed, insured work. You may need a stained pool deck or a reinforced parking lot. You may need a simple walkway replacement. Either way, our team plans each pour around San Antonio's climate and soil.
San Antonio sits in a humid zone with long, hot summers and mild winters. That heat cycle puts real stress on concrete surfaces all year. The city's clay-heavy soil expands and contracts with seasonal rainfall. That is why proper base prep and steel work matter more here than in drier regions. The city has over 1.4 million residents. It also has a fast-growing housing and business market. Demand for quality concrete work keeps climbing across the metro. San Marcos Custom Concrete stays licensed and insured. Property owners in San Antonio get a crew that knows local building codes and weather demands.
Frequently Asked Questions
How much does a new concrete driveway cost?
Most driveways in this area run about $7.50 to $11.50 per square foot for plain broom-finish work. A standard two-car drive (400 sq ft) often lands between $3,000 and $4,600 for the pour. We measure your site and give you a firm price in writing.
How thick will the concrete be?
Driveways and patios are poured 4 inches thick in most cases. Heavy truck or RV areas get 5 to 6 inches. We set rebar or fiber mesh in the slab for strength.
How long before I can drive on it?
You can walk on new concrete in about 24 hours. Park cars on it after 7 days. Heavy trucks should wait about 28 days while the slab reaches full strength.
Do you tear out the old concrete?
Yes. We break up and haul the old slab, grade the base, and compact fresh gravel before we pour. Tear-out and haul-off are in the written price.
Will my new concrete crack?
All concrete can crack in time. We cut control joints in the right spots so cracks follow the joints, not the slab face. Good base work and the right mix cut the risk a lot.
How long does a job take?
Most patios take 2 days. Most driveways take 3 days. Large or stamped jobs take 4 to 5 days. Weather can add a day.
What Does My Concrete Project Cost?
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.
Concrete Driveway
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.
Concrete Patio
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.
Slabs & Foundations
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
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.
Repair & Resurfacing
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.
What Moves the Price
- Finish. Plain broom is the baseline. Stamped, exposed aggregate, and stained finishes add materials and skilled labor — stamped work can run close to double a plain pour.
- Thickness. Four inches is standard for cars and foot traffic. Six inches — for RVs, work trucks, hot tubs — uses half again as much concrete on every square foot.
- Tear-out. Breaking out and hauling off old concrete is its own line, priced per square foot on top of the new pour.
- Job size. Small pours carry a minimum charge and short-load fees from the concrete plant; on big pours the setup spreads over more feet.
- Ground. Central Texas clay swells when it is wet and shrinks hard in a drought, and that movement cracks slabs that were poured on a thin base. Base work is in every price here — it is not an extra.
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.
Estimate Your Project
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.

Commercial Concrete Design for San Antonio Businesses
Our crew handles business concrete design for retail centers, offices, and industrial sites across San Antonio, TX. We map out slab thickness, jointing, and drainage before the first truck arrives on site. San Marcos Custom Concrete works with property managers to schedule pours around business hours when we can. Business clients get a written scope with material specs. There are no surprises mid-project.
Residential Driveway and Walkway Installation
Homeowners across San Antonio rely on us for driveway and walkway work. It holds up to daily traffic and summer heat. We grade the base, set forms, and pour to a steady thickness. The surface resists cracking over time. Our crews finish each driveway with a broom or trowel texture. The pick is based on the homeowner's taste. San Marcos Custom Concrete completes most home driveways within a few working days.
Patio and Pool Deck Construction
Patios and pool decks need slip-resistant finishes and proper slope. San Antonio's rainy spring months demand both. We build pool decks with textured surfaces. They stay cooler underfoot during the region's hot summers. Our team routes drainage away from the home's foundation on each patio pour. San Marcos Custom Concrete uses control joints spaced the right way. They prevent random cracking across large deck areas.
Multi-Surface Flatwork Coordination
Larger properties often need driveways, walkways, and patios poured together in one project. Our schedule accounts for cure times between each surface. Foot traffic won't damage fresh concrete. We sequence the pours to keep the property open during the work when the layout allows it. San Marcos Custom Concrete assigns one crew lead to multi-surface jobs. Specs stay steady throughout.
Stamped, Stained, and Decorative Concrete Finishing for San Antonio Properties
San Marcos Custom Concrete offers stamped, stained, and decorative finish options. They turn plain slabs into standout features. We match colors and patterns to the style of homes and business buildings across San Antonio.
Stamped Concrete Pattern Selection
Stamped concrete lets property owners mimic stone, brick, or slate. They skip the cost of natural materials. Our crew presses patterns into the surface while the mix is still workable. We lock in texture before it cures. We offer dozens of stamp patterns suited to San Antonio's Southwestern and Hill Country building styles. San Marcos Custom Concrete seals each stamped surface. That protects the pattern from fading in the Texas sun.
Acid Staining and Color Application
Acid staining reacts with concrete to produce mottled, earth-toned finishes. They never fully repeat. Our team applies stains in layers. We build depth and variation across patios, floors, and driveways. San Antonio homeowners often choose warm terracotta and amber tones. They fit local stucco and stone exteriors. We test color samples on-site before we commit to full application. That avoids costly mismatches.
Decorative Overlay and Resurfacing Options
Decorative overlays refresh worn concrete without a full tear-out and replacement. Our crew applies thin polymer-based coatings. They accept stamping, staining, or texture just like new concrete. San Marcos Custom Concrete resurfaces cracked patios and faded driveways across San Antonio. The cost is a fraction of replacement cost. Property values often improve in a clear way once a dated slab gets a decorative overlay upgrade.
Commercial Floors, Parking Lots, and Structural Slabs Across San Antonio, TX
Business properties need slabs built for heavy loads and constant traffic. They need long-term strength too. San Marcos Custom Concrete builds structural flatwork for warehouses, retail lots, and multi-family projects across San Antonio.
Structural Mix PSI Ratings and Reinforcement
Business slabs in most cases require 3,500 to 4,500 PSI mixes. The right pick depends on the expected load and traffic pattern. Our team reinforces high-traffic areas with rebar or wire mesh. They resist cracking under vehicle weight. San Marcos Custom Concrete picks PSI ratings based on soil reports and projected usage for each San Antonio site. Parking lots and loading docks in most cases need the higher end of that PSI range.
Commercial Parking Lot Construction
Parking lots demand precise grading. Water should drain toward catch basins, not pool near entrances. We compact the sub-base with care before we pour. San Antonio's clay soil shifts more than sandy ground. San Marcos Custom Concrete pours parking lots in sections. That controls shrinkage cracking across large surface areas. Business clients get an upkeep schedule after the install. It extends the lot's life.
Topcoat Sealers and Protective Coatings
Sealers protect business floors from oil stains, UV fading, and moisture. All three are common in Texas summers. Our crew applies penetrating or film-forming sealers. The pick depends on the floor's exposure and expected foot traffic. San Marcos Custom Concrete suggests resealing business surfaces every two to three years. That maintains protection. Warehouses and retail floors both gain from a sealer matched to their wear patterns.
