We work with developers, property managers, and general contractors. They need strong custom concrete that meets code and holds up under heavy traffic.

We match the mix design, thickness, and steel to your load needs.
Seguin has earned the nickname "the Mother of Concrete Cities." Nearly 100 limecrete structures were built here in the 1870s. That legacy still shapes how residents think about strong construction. The city sits on the northern edge of the South Texas Plains. Hot, humid summers push temperatures into the low-to-mid 90s. Winters stay mild, with fast-moving cold fronts called northers at times. The city has over 36,000 residents. Steady business growth near Interstate 10 and Highway 123 adds to the demand. Seguin property owners need concrete that resists heat cracking, heavy rain, and shifting clay soil.
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 Parking Lots, Floors, and Structural Slab Construction in Seguin, TX
San Marcos Custom Concrete designs and installs parking lots and structural slabs in Seguin. We also install interior floors for business properties. Our promise is simple. We plan each slab around your site's traffic, drainage, and load needs before a single yard of concrete gets poured.
Parking Lot Layout, Slab Thickness, and Traffic Flow Design
Parking lot layout decides how well a business lot handles daily traffic and delivery trucks. It also decides long-term wear in Seguin. We map drive lanes, striping, and ADA-compliant spaces before construction begins. The finished lot moves vehicles safely and with ease. Our crew sets slab thickness based on expected load. In most cases that means 5 to 6 inches for standard parking and up to 8 inches near loading zones. San Marcos Custom Concrete grades each lot for proper drainage. That matters most during Seguin's heavy spring and fall rain events.
Warehouse and Industrial Floor Slab Construction
Warehouse floors need a slab that can carry racking systems, forklifts, and constant gear traffic without cracking. Our team pours industrial floors with high-strength mix designs. They suit the weight loads common in Seguin's growing distribution and manufacturing sector. We control joint spacing and surface flatness with care. Uneven floors slow down forklift work and add gear wear. Local manufacturers depend on floors that meet strict flatness standards. They include firms that supply the automotive and steel industries near Seguin.
Retail and Office Building Entry and Sidewalk Concrete
Retail and office entries create the first impression a customer or tenant gets of a Seguin business. We form and pour entry slabs, sidewalks, and ramps. They meet the slope and access standards that local code requires. Our crew finishes these surfaces to resist slipping. That matters during Seguin's frequent summer storms and humid mornings. San Marcos Custom Concrete times entry work with landscaping and signage crews. Property owners get a clean, finished look on schedule.
Heavy-Duty Concrete Mix, Reinforcement, and Commercial Material Standards for Seguin Businesses
Business concrete demands a different mix and steel standard than home work. San Marcos Custom Concrete builds each slab to match. We source materials rated for the loads, traffic, and climate conditions found across Seguin, TX.
High-Load PSI Mix for Commercial and Industrial Slabs
High-load work requires a concrete mix strong enough to carry heavy vehicles, racking, and gear without breaking down. Our team specifies 4,000 to 5,000 PSI mixes for most business and industrial slabs. We adjust upward for special loading zones. We pick aggregate and cement ratios based on the use case. A retail sidewalk and a warehouse floor carry very different demands. This mix strength gives Seguin property owners a slab built to last decades under daily business use.
Rebar Grid Spacing and Fiber Additive Specifications
Steel keeps a business slab from cracking under load. Temperature swings and soil movement are common in this part of Texas. Our crew places rebar grids at intervals matched to slab thickness and expected traffic. In most cases that means 12 to 18 inches on center for heavy-use areas. We also add synthetic fiber to many mixes. That cuts shrinkage cracking during Seguin's hot summer cure periods. San Marcos Custom Concrete documents each steel layout. It is ready for inspector review.
Sub-Base Compaction and Vapor Barrier Standards
Sub-base prep decides whether a slab stays level and crack-free for years or fails within a single season. Our team compacts the sub-base to spec before any concrete gets poured. We account for Seguin's clay-heavy soil. We install vapor barriers under interior slabs to block moisture. That protects flooring materials and gear above. This prep work costs less upfront than a failed slab repair. It is a step our crew never skips.

Our crew builds apartment complex concrete to withstand heavy daily use. It also meets access needs for residents and visitors. We plan drainage with care around these properties.

Commercial Concrete Permits, Inspections, and Code Compliance in Seguin, TX
Each business concrete project in Seguin has to clear permits and inspection before it counts as finished. San Marcos Custom Concrete manages this process directly. Property owners don't have to navigate it alone.
Building Permit Application and Plan Review Process
Building permits require detailed plans before the City of Seguin approves any business concrete work. Our team prepares and submits these plans for city review. They include slab specs, steel layouts, and drainage details. We track the review timeline with care. We respond fast to any requests for revisions from plan reviewers. San Marcos Custom Concrete has submitted plans through this process many times. We can foresee common questions before they slow a project down.
ADA and Accessibility Requirement Compliance
Access rules affect ramp slopes, sidewalk widths, and parking space dimensions on each business property in Seguin. Our crew builds entry ramps and walkways to meet ADA slope needs. This in most cases cap at a 1:12 rise-to-run ratio. We also size and place accessible parking spaces per the space count that lot size requires. Getting this wrong after the concrete cures means costly demolition and repour. We verify each measurement before we pour.
Stormwater, Drainage, and Impervious Surface Permits
Stormwater control matters on each business pour. New parking lots and slabs increase the hard surface on a property. Our team works out drainage needs. We coordinate with city staff to secure the correct permits before construction starts. We grade each large concrete surface to direct water toward approved drainage points. Water does not flow toward neighboring properties. This planning protects Seguin property owners from drainage violations. Violations can delay a certificate of occupancy.
