A garage floor starts with what's underneath

Garage floor concrete in Mission, TX is a new slab poured over ground we've dug out and packed hard. When an old garage floor cracks or sinks at one side, the cause is usually underneath. The subgrade, the dirt the slab sits on, was raked smooth and never compacted, so the slab settled with it. That's where I spend the time first.

The price turns on the size of the floor, how much digging the base needs, whether we add steel and any color or stamping, which is decorative concrete work. The schedule turns on the permit, the weather and curing, the wait while the slab gains strength before you use it. We're licensed and insured, and your own figure comes from the quote I write after I measure.

  • Soil dug out and the base packed firm
  • Steel held up inside the slab, not on dirt
  • Joints cut where we want cracks to go
  • Poured in the cool hours, not midday heat

Where the money should go

Every bid splits the budget between what's under the slab and what's on top, and the base gets cut first because nobody sees it on day one.

  • Finish first

    What you get
    A nice surface poured over dirt that was raked level, not packed.
    The catch
    The base settles with the dirt, and the slab cracks and sinks.
  • Base first

    What you get
    A packed base, steel held up, planned joints and a broom finish for grip.
    The catch
    Most of your money goes where you'll never see it. That's the right trade.
  • Base plus extras

    What you get
    The same solid base with a coating, color or a lift planned in.
    The catch
    Every extra has to be planned before the pour, and each one adds cost.

How we plan and pour it

  1. You reach us

    Call (956) 379-6556 or send the form, and tell us your garage size and whether you're planning a coating or a car lift.

  2. I measure and quote

    I come out myself to measure, look at the ground and how water moves across it, and write a quote that spells out each part of the job.

  3. Permit, forms and base

    We sort out any permit and set the date once it's issued, then set the forms, check the grades and pack the base in layers.

  4. Pour day

    Our crew pours with me on site, timed around the weather, and the steel rides on supports inside the slab instead of lying on the dirt.

  5. Joints and clean-up

    We cut control joints, shallow grooves that give shrinkage cracks a planned place to form, then clean up and go over when you can use the floor.

Decide these before the pour

A lift, a coating or the ground around the garage can change how thick we pour, where the joints go and what the quote says, so settle them first.

  • Planning for a car lift

    A lift needs a thicker slab with the joints laid out around the posts. One garage-slab guide puts the minimum at 4-1/4 inches, so tell me before we pour.

  • A coated floor

    If you'll coat the floor, the same guide says a vapor retarder under the slab is worth having, since soil moisture rises through it. A bare floor in an unheated garage doesn't.

  • Pouring in steady heat

    Mission's climate is subtropical, and hot-weather guidance says to pour during cooler hours, even at night, so we'll usually suggest a cooler start time and plan garage access around it.

  • Thickness in the bid

    Residential slabs around McAllen usually run four to six inches thick, with garages at the thicker end, so check that a bid states the thickness and how the steel is held up.

  • Ground around the garage

    Where a garage sits below a slope or the yard needs holding back, a concrete retaining wall may need to come first so soil and runoff stay off the new slab.

What a good garage slab looks like

Look for straight, evenly spaced joints, a clean edge at the door and a surface that isn't dusty or flaking. Open any example to see it up close.

How much does a new concrete garage floor cost near Mission, TX?

A concrete slab in nearby McAllen usually costs about $5 to $11 per square foot, before any staining or stamping. Steel reinforcement adds a little per square foot, and stain or stamping adds more. Whatever your number comes to, it's satisfaction guaranteed on every job.

Do I need a permit to pour a garage floor in Mission, TX?

Yes. The City of Mission requires a permit for any concrete slab worth $100 or more, and a garage floor is well past that. We handle the application with the city's Inspections Division, at 956-580-8691, and set the pour date after it's issued.

How long after pouring can I park on my new garage floor?

Plan on about a week before you park on it, to be safe. A new slab should be walkable within 48 hours, but concrete takes about a month to fully cure, so it's wise to hold off on heavy loads for that first week. Line up somewhere else for the cars until then.

Will my new concrete garage floor crack like the old one?

It may show fine cracks, and that's normal, but they're meant to land in the joints. Even a well-designed, well-built slab isn't fully crack-free, which is why we cut joints to decide where shrinkage cracks go. A thin crack along a joint line just means the joint is doing its work.
