About San Marcos Custom Concrete
San Marcos Custom Concrete has been pouring concrete in San Marcos, TX and the towns around it for over 20 years. From day one, the focus has been simple: concrete that holds up and looks good doing it.
In that time, we have built driveways, patios, slabs, foundations, and walkways. We have poured stamped concrete and done repair work on homes and businesses of all sizes. We started this company on a simple belief. A concrete crew should care about how the work looks, not just how strong it is. Texas heat, heavy loads, and sudden storms all beat on concrete. Good work has to stand up to all of that. It should also make your property look better and worth more.

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.

San Marcos Custom Concrete does custom concrete work the right way. We talk plain, plan with care, and build work you can count on. Each job starts with the space itself — what it is for, and what you want it to look like. A basic slab or a detailed stamped patio gets the same care, from the ground up.
Our goal is simple. We give owners concrete that is strong and good-looking. We build it around your real needs, not a one-size-fits-all plan. We keep the process smooth. And we do work you can trust for years.
Our Vision
We want to be one of the most trusted concrete companies in San Marcos, TX and the towns around it. Owners should know us for work that lasts, clean finishes, and service that earns trust at each step of the job.
San Marcos is growing fast. New homes, businesses, and outdoor spaces all need concrete that is built right. A new driveway, a custom outdoor living area, a foundation, or a repair job — our goal is the same. We leave every property better than we found it.
