Office hours 8 AM–6 PM daily
Concrete work we take on
- Driveways: new or widened drives, parking pads beside a shop and replacement of broken sections. Long rural drives can mix concrete near the house with gravel beyond.
- Patios: back patios and grill pads, sized for a future patio cover with post footings planned before the pour.
- Sidewalks: walks from the drive to the front door or out to a shop, with steps where the grade drops.
- Shop and barndominium slabs: floors for metal buildings, garages and workshops, matched to the building drawings and the finish-out that follows.
- Small building pads: slabs for storage sheds and tiny homes.
- Culverts and aprons: the pipe under your drive at the road ditch and the short concrete section that ties the drive to the road edge.
Site prep, base, steel and curing, explained plainly
A slab depends on what sits under it. The usual order:
- Layout and locates. We mark the outline and have buried lines marked through Texas 811 before anyone digs.
- Strip and grade. Grass, roots and soft topsoil come out, and the subgrade is shaped to drain away from the building and compacted.
- Base. A compacted base layer gives the concrete a firm, even bed. Its material and depth depend on the soil and the load.
- Forms and steel. Forms set edges and slope. Rebar or mesh rests on supports so the steel ends up inside the concrete, not on the dirt.
- Pour, finish and joints. The concrete is placed, leveled and finished, often with a broom texture for traction. Control joints give shrinkage cracks a planned place to form.
- Curing. Concrete gains strength for weeks, and keeping the surface from drying too fast with water or a curing compound helps. Foot traffic comes first; vehicles wait longer.
What decides how thick it should be
There is no single right thickness. It depends on what will drive or sit on the slab (a car, a loaded trailer, a tractor), the soil, the base and where loads concentrate, such as edges and building columns. Wilson County land is generally loamy soil over clayey subsoil, and clay moves as it wets and dries. Foundation drawings from a building supplier or engineer set the thickness, beams and steel when they exist. Your estimate explains what we recommend and why.
Why fall and early winter suit pours in South Texas
Concrete hardens through a chemical reaction that heat speeds up. On a July afternoon the surface can stiffen and dry before finishing is done, raising the odds of surface cracks, so summer pours often start at first light.
Milder fall afternoons give the crew more time and let the slab cure more evenly. Wilson County winters are generally mild, but January lows average around 40 degrees, so a cold front can still bring frost. We watch the forecast, cover fresh slabs ahead of a cold night and don’t pour on frozen or soaked ground.

Driveway culverts and county permits in Wilson County
Where a driveway crosses the ditch of a county-maintained road, that strip is public right-of-way and needs a county permit. The county’s right-of-way rules, approved by Commissioners Court on April 27, 2026, cover driveways, culverts, sidewalks and earthwork. Applications go to the Wilson County Permitting and Development Office, 800 10th Street, Building B, Floresville, and right-of-way work waits until the permit to construct is signed. Key points:
- Culverts must be corrugated metal or reinforced concrete pipe, at least 18 inches across unless the precinct commissioner approves otherwise.
- Culvert ends need a sloped end treatment of at least 3:1, and the driveway radius can’t be under 6 feet.
- The drive should stay within your frontage, and roadside ditch drainage can’t be blocked.
- Concrete driveways get a county pre-pour inspection, and caliche isn’t accepted as base in the right-of-way.
- A permit to construct covers 180 days, with a county inspection once the work is reported complete.
Other roads, other rules: for a drive onto a state highway, the county sends owners to TxDOT. Inside La Vernia, flatwork is a building permit category, city right-of-way work has its own application, and Bureau Veritas handles plan review and inspections, including one before concrete is placed. Floresville has its own Buildings and Permits department.
Your project’s permits are applied for before work starts, and since the county revised its rules this year, we confirm current requirements for each job. More on our La Vernia and Wilson County permits page.
Concrete on acreage near St. Hedwig, Adkins, Floresville and La Vernia
On rural lots we plan the heavy ready-mix truck’s route to the pour, keep it off septic drain fields and soft pasture, and decide whether a pump suits a slab far from the road. Much of this country is nearly flat, so slabs need deliberate fall to shed water.
St. Hedwig is a town in eastern Bexar County and Adkins is an unincorporated community nearby, so road rules there depend on whether the town, Bexar County or TxDOT maintains the road (FM 1346, FM 1518 and Loop 1604 are state roads); we check before forming. In a subdivision, deed restrictions may also govern driveway materials, and Wilson County doesn’t enforce those, so read yours first. Area pages: St. Hedwig and Adkins, Floresville and Stockdale, where a drive onto a county-maintained road follows the same Wilson County right-of-way rules.
What to send with your estimate request
- The address, and whether the drive meets a county road, state highway or city street.
- What you want poured and rough dimensions, even paced off.
- What will use it: cars, a truck and trailer, a tractor or a shop floor.
- Photos of the spot, the ditch and any existing slab.
- Building drawings or an anchor bolt plan for a shop or barndominium.
We’ll walk the site and put the base, steel and joint plan in writing. Ready-mix is batched for your pour and steel is cut to your forms, so the rule is no cancellations after materials have been purchased.
Concrete questions
Do I need a permit for a driveway culvert in Wilson County?
If the driveway connects to a county-maintained road, yes. The culvert and apron sit in county right-of-way, which needs a permit from the Wilson County Permitting and Development Office, and concrete drives get a pre-pour inspection. State highways go through TxDOT; city streets go through the city.
How thick will my driveway or slab be?
It depends on the loads, the soil, the base and any engineered or supplier drawings. Your written estimate states the recommended thickness, steel and base rather than one number for every job.
Can concrete be poured in winter?
On most winter days, yes. Cold slows the reaction that hardens concrete, so a winter slab may need extra days before the forms come off or vehicles drive on it, and the pour is moved if a hard freeze is forecast.
Will my new concrete crack?
Concrete shrinks as it dries, so fine cracks are common. A firm base, well-placed control joints and careful curing help keep cracking at the joints, where it is least noticeable.
