Schertz sits within the San Antonio–New Braunfels metro area. It has grown into a community of roughly 44,000 residents, per recent Census Bureau estimates. Hot, humid summers and heavy rainfall at times put real stress on concrete surfaces. Proper drainage grading and PSI selection are key for local projects.

San Marcos Custom Concrete gives Schertz property owners a contractor they can trust. Our flatwork is built to code.
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.

Concrete Flatwork, Slabs, and Surface Construction Services in Schertz, TX
San Marcos Custom Concrete handles flatwork projects in Schertz. We serve business properties and homes across the city. Our work runs from small walkways to large multi-slab installs. Our crew checks soil conditions, drainage patterns, and traffic loads. We do that before we suggest a mix design and steel plan for your project.
Driveway, Patio, Sidewalk, and Walkway Flatwork Builds
Our team pours driveways, patios, sidewalks, and walkways built to handle Schertz's expansive clay soil and temperature swings. We grade each site to move water away from foundations before any concrete gets poured. Business parking areas and home driveways both get proper base compaction and joint spacing. That prevents early cracking. San Marcos Custom Concrete finishes each surface with a broom or stamped texture. The pick depends on the property's needs.
Concrete Slab for Additions, Sheds, and Garage Pads
We pour slabs for home additions, storage sheds, garage pads, and workshop foundations across Schertz. We serve nearby communities too. Our crew sizes each slab's thickness and steel to match the structure's expected load. We also match local building code needs. Vapor barriers go beneath slabs that support living spaces. They control moisture from the ground. San Marcos Custom Concrete times our work with your contractor. Framing can begin without delay.
Pool Deck and Outdoor Entertainment Area Slabs
Our crew builds pool decks and outdoor slabs that stay cool and slip-resistant during Schertz's hot summer months. We suggest broom-finished or textured surfaces near pools. Smooth concrete becomes slick when wet, and that is a danger. Expansion joints go around the pool shell. They absorb ground movement without cracking the deck. San Marcos Custom Concrete also grades outdoor slabs to drain away from the home's foundation.
Concrete Material Specifications and Construction Quality in Schertz, TX
San Marcos Custom Concrete picks mix designs, steel, and coatings based on each project's use. We also weigh exposure to Schertz's climate. Business clients and homeowners both gain from material picks matched to traffic and weather.
PSI Mix Selection for Residential and Commercial Slabs
Our crew picks concrete strength based on the slab's purpose. In most cases we use 3,000 PSI for home walkways and 4,000 PSI or higher for business drive lanes. Business properties with delivery trucks or heavy gear require stronger mixes than standard home driveways. We factor in Schertz's freeze-thaw cycles, though mild compared to northern states. We also factor in summer heat when we choose additives. San Marcos Custom Concrete never cuts corners on mix design, no matter the project size.
Wire Mesh, Rebar, and Expansion Joint Standards
We reinforce slabs with wire mesh or rebar. The pick depends on the load needs and soil movement common in Guadalupe and Bexar counties. Rebar gets specified for driveways, business pads, and any slab that will bear vehicle weight. Expansion joints get cut or formed at steady intervals. They control where cracking occurs as the concrete cures. San Marcos Custom Concrete follows industry spacing standards. Joints function as planned, not as afterthoughts.
Sealer and Coating Selection for Outdoor Surfaces
Our team applies sealers and coatings matched to each surface's sun exposure and foot traffic level around Schertz properties. Penetrating sealers work well for driveways. They resist UV breakdown without leaving a slippery film. Decorative coatings get picked for patios and pool decks. Homeowners want added color or texture there. San Marcos Custom Concrete suggests resealing every two to three years. That maintains protection against Texas heat and rain.
Concrete Services for Homeowners, HOAs, and Neighborhood Communities in Schertz, TX
San Marcos Custom Concrete serves single-family homeowners, HOAs, and neighborhood groups across Schertz. We size flatwork to fit each community's needs. Our schedule handles everything from single driveways to multi-phase common area projects.
Single-Family Home Driveway and Patio Projects
We pour driveways and patios for homeowners across Schertz. We work around existing landscaping and property lines on each project. Our crew walks each site with the homeowner before we pour. We confirm layout, drainage direction, and finish choices. Small home jobs get the same base prep and steel standards as larger business work. San Marcos Custom Concrete in most cases completes standard driveway pours within one to two days. The exact time depends on square footage.
HOA Common Area Sidewalk and Amenity Concrete Work
Our team handles sidewalk repairs and amenity center slabs for HOAs in Schertz. We also handle common area concrete for HOAs that manage shared spaces across Schertz neighborhoods. HOA boards often need phased schedules. Pool areas, clubhouses, and walking paths stay open during the work. We coordinate with property managers to cut disruption. We also meet community deadlines and budget limits. San Marcos Custom Concrete has poured amenity slabs of many sizes. They range from small mailbox kiosks to full clubhouse patios.
Neighborhood Community Entry and Feature Concrete
We build entry monuments, decorative walkways, and feature slabs. They give Schertz neighborhoods a polished entrance that works as one design. Stamped or colored concrete gets used often for entry features. It adds curb appeal without the upkeep of pavers. Our crew works with landscape architects and developers. We match concrete finishes to the community's overall design plan. San Marcos Custom Concrete has completed entry features for many projects across the Randolph Metrocom.
Concrete Safety, ADA Compliance, and Code Standards in Schertz, TX
San Marcos Custom Concrete builds each walkway, ramp, and public-facing slab to meet ADA needs and local Schertz code standards. Business properties and HOA common areas face stricter rules than typical home driveways.
ADA-Compliant Walkway and Ramp Installation
Our crew builds ramps and walkways that meet ADA slope, width, and landing needs. They serve business properties and HOA common areas in Schertz. Slopes cannot exceed a 1:12 ratio. Landings need specific dimensions at doorways and direction changes. Businesses open to the public carry legal duty for access routes across their property. Those routes must stay compliant. San Marcos Custom Concrete checks measurements against current code before we finalize any public-facing walkway.
Non-Slip Surface Requirements for Outdoor Concrete
We finish outdoor surfaces with broom textures or special coatings. They meet slip-resistance standards near pools, ramps, and entryways. Smooth-troweled concrete looks appealing. But it becomes a hazard once wet, most of all during Schertz's frequent summer storms. Business entrances and HOA pool decks both require finishes tested for grip under code. San Marcos Custom Concrete picks the right texture based on where the surface sits and how much moisture it will see.
Drainage Grade and Permit Compliance for Flatwork
Our team grades each slab to direct water away from structures and property lines. We meet Schertz's stormwater and drainage rules. Poor grading is one of the most common reasons flatwork fails inspection. It also causes foundation problems down the road. We pull required permits before we break ground. Projects avoid delays or costly rework later. San Marcos Custom Concrete has passed inspection on projects across Guadalupe, Bexar, and Comal counties.
