Fifty-eight mornings at or below freezing and twenty-four days at or above 100 degrees Fahrenheit: those are the 1991 to 2020 normals at Midland International Airport, along with about 13.51 inches of precipitation a year. A slab placed on this ground has to handle both ends of that range, and the calendar for its pour has to reflect it.
A slab on grade is a floor cast directly on prepared soil, with no framing underneath. Its performance depends heavily on what is under it, on how the joints are laid out, and on how quickly the surface is protected after finishing. The troweling gets noticed, but the base and the cure do the real work.
Concrete Contractors of Midland places slabs for spec offices, shops, medical buildings, warehouses and processing sites. We work from the engineer's drawings, agree on the joint plan in advance, and give the owner a pour calendar that accounts for batch plant haul time and the owner's own operating schedule.
Concrete operations and trade handoffs
Concrete trade partners set screed lines, place reinforcing where the design calls for it, place and finish the concrete, saw the joints and apply curing. That covers the work that determines how a slab looks and performs, and it keeps one team accountable for flatness and finish.
For earthwork, base preparation and underslab utilities we coordinate trade partners. We tie their schedule into ours so the base is proven and the plumbing rough-ins are inspected before the concrete trade partner shows up. When a rough-in inspection slips, we say so and move the pour date instead of covering unapproved work. A slab crew arriving at an unfinished base wastes a day, and the mix in the truck does not wait.
From subgrade proof to cure
We start with the subgrade. Caliche and imported base are checked for compaction and moisture, soft spots are corrected, and the vapor barrier or sand layer called for in the drawings is installed and protected. On pour day we confirm elevations, check the mix ticket and set the placement sequence.
Finishing starts once bleed water leaves the surface, not before. Joints are cut early enough to control cracking, and curing begins right behind the final pass. In summer we add evaporation control and place early. In a cold snap we protect the slab with blankets so the surface does not freeze while it is green. We also ask the finishing crew to walk the slab at the end of the day, since early marks and plastic cracking are easiest to correct while the concrete can still be worked.
Corridors and projects that drive slab demand
Midland's growth is visible in its road projects. TxDOT has proposed new Loop 250 main lanes running from Fairgrounds Road out to CR 1150 (Elkins Road), with a Todd Drive overpass, and its public comment window closed July 10, 2024. A September 4, 2025 City of Midland release lists a TxDOT signal project at I-20 and Cotton Flat Road as awarded, along with Garfield and Florida and Garfield and Front Street.
Each of those corridors brings new access to land that will need slabs for shops, offices and retail pads. We follow the schedules because they affect truck routes and, indirectly, which sites open up. At the Basin level, the Spraberry and Wolfcamp shale intervals are the main horizontal drilling targets, and the work they support shows up as yard and building slabs around town.
Services that connect to the slab
A slab seldom stands alone. Footings and stem walls provide the edge and bearing, sidewalks and flatwork connect the building to the parking, and concrete paving carries vehicles around it. Quoting these together lets us plan joints and elevations across the whole site.
Where an owner needs a high-performance floor, we also discuss polished concrete floors and other surface options early, because the mix, finish timing and cure for those floors differ from a standard broom finish.
Who buys slabs from us
The mix of clients we serve is broad. Commercial developers want pads ready for tenants. Industrial and manufacturing owners want floors that handle trucks and racking. General contractors and CM firms want a concrete partner that keeps schedule promises.
Each calls for a different conversation. We ask about loads, traffic, finish and operating hours, then pass the questions that belong to the engineer, such as thickness and reinforcing, back to the design team rather than guessing at them. Our job is to build what is drawn and to flag it when the drawn slab does not fit the way the building will be used.
What the slab package covers
A complete slab package includes base verification, vapor barrier installation or coordination, reinforcing placement, edge forming, placement, finishing, jointing, curing and cleanup. We also record the mix tickets and coordinate cylinder testing with the owner's agency.
Optional items include hardeners, sealers and special finishes, and we price them separately so owners can compare. Where the drawings call for thickened edges, pits or embeds, we list them as part of the scope rather than leaving them as surprises.
Where we place slabs
We serve Midland and the surrounding Permian Basin communities, including Odessa, Big Spring and smaller towns along I-20. We mobilize crews to each site, and haul distance from the nearest plant is part of the calendar.
A slab placed twenty minutes from a plant is a different task from one placed an hour away, so we adjust mix design, truck spacing and crew size to match. Remote locations also change how we stage forms, steel and finishing tools, since a forgotten item cannot be fetched in ten minutes. We load the truck against a checklist before it leaves.

Common Questions
How thick should my slab be?
The engineer picks thickness from the expected loads and the soil. A quiet office floor and a warehouse full of forklifts call for very different designs. Concrete trade partners follow the plans, and we flag it when the stated loads and the drawn thickness look out of step.
Why do slabs crack even when poured correctly?
Fresh concrete loses volume as it hardens, so a few hairline cracks are normal and sawn joints steer them to chosen lines. A weak base, fast drying and late saw cuts turn that into real damage, which is why those three get our attention.
Can you pour in Midland's summer heat?
Yes, if the day is planned for it. We book pours at first light, ask the plant for a cooled mix, spray retarder on the surface and start curing the moment finishing ends. When hot wind would dry the top before the crew can close it, we move the date.
Do you install the vapor barrier and the base?
We coordinate both, and we furnish them when the scope says so. Barrier sheets need overlapped, taped seams and protection from chair legs and boot traffic, or moisture will find a way up.
What flatness should I expect from a standard slab?
A typical commercial slab is finished to ordinary tolerances. Where racking or machinery demands more, say so during bidding and we will add the machines and finishing hours that requires. Our super flat floor slabs page explains that work.
