Industrial Concrete Floors in Wyoming

Slab curl, not the pour itself, ruins most industrial floors. Corners lift, joints open and a forklift starts bouncing at the dock door. Wyoming adds dry wind, wide temperature swings and frozen subgrade, which make the usual problems arrive faster. We build industrial floors to avoid them.

The floor is what the owner actually uses every day. Racking loads, forklift traffic, point loads from machines and the wear of steel wheels all land on it. A floor in a distribution building has to stay flat. A floor in a process plant has to resist chemicals and wash-down. A floor in a freezer has to stay dry under the slab. Each of those is a different design and a different pour.

The market keeps asking for large slabs. Cheyenne Business Parkway is a 900 acre park with utilities in place and tenants that include a regional distribution center. Sheridan's Kennon Products broke ground on a 35,000 square foot corporate and manufacturing building in the Sheridan High-Tech Business Park. Different scales, same demand for a slab that stays level.

Slabs we place

We pour slab-on-grade floors for warehouses, manufacturing buildings, shops and cold rooms. Typical work includes subgrade preparation, vapor retarders where the use calls for them, reinforcement or fiber, embeds and trench drains, floor hardeners and sealers. We coordinate dock pits, equipment pads and slab depressions with the building design, since cutting those in later costs more than forming them.

Equipment bases, racking footings and heavy machine foundations often sit within the slab or beside it. Our equipment pads and foundations work coordinates those, and the slab around them is placed so joints fall on column lines and not through a machine base. Building shells go up faster when the floor, pads and walls follow one plan; see our warehouse shell construction for how it all fits.

Subgrade, joints and flatness

A floor is only as good as the ground under it. We prove the subgrade with a proof-roll, replace soft or frozen material and place a uniform base. Variations in support make slabs curl and crack. We then lay out joints on a grid that follows columns and racking, saw-cut at the right time, and design the details at doors and thresholds where cracks like to start.

Flatness depends on method. Laser screeds, straightedge checks and F-number measurement after placement are standard where racking and narrow-aisle trucks demand tight tolerance. We agree on the target with the owner before the pour, not after, because a very flat floor costs more and some operations do not need it. Finishing crews, power trowels and curing materials are staged before the first truck arrives.

Who finishes the concrete

Concrete finishing is a skill that cannot be rushed or handed off. We require experienced finishers, placing crews and a field engineer who owns the sequence and the QC on our floor pours. That matters when the mix is stiffening and the pump is behind. A decision in the middle of a pour is made by someone who has been there.

We pair that with a ready-mix supplier relationship that keeps trucks moving and a testing agency on site for slump, air and cylinders. Whether the pour is a large warehouse slab for a distribution center or a smaller slab in a shop, the routine is the same: pre-pour meeting, checked forms, tested mix, finish, cure.

Cold and wind decide the day

Rawlins has recorded temperatures from 98 F to minus 36 F and gets about 54 inches of snow a year. Frozen subgrade cannot be poured on. In winter we enclose and heat the building before placement, thaw the ground, keep the slab above freezing until it gains strength and monitor temperature with embedded sensors. Heat and blankets cost money, but a frozen slab costs more.

Wind is the quiet problem. Dry air and gusts pull moisture from the surface, causing plastic shrinkage cracks before the finishers are done. We close the building envelope where we can, set windbreaks, use evaporation retarders and start curing the moment the surface permits. Pour start times are set by the forecast, not by convenience.

Tolerances, testing and local codes

Floor specifications run from the designer's requirements: slab thickness, reinforcement, joint spacing, flatness and levelness, hardener and curing methods. We submit mix designs, joint layouts and a pour plan before work starts. Testing includes slump, air content and compressive strength cylinders, and flatness measurements on the slab itself.

Local building departments adopt and enforce their own codes. The state adopted its 2024 International Codes on June 28, 2024, and cities and counties with delegated authority adopt their own editions. For floors in cold storage and refrigerated buildings, underslab heating and insulation are part of the design, and we coordinate those with the refrigeration contractor so a freezer floor does not heave the building.

What changes the price of a floor

Thickness and reinforcement drive material cost. Flatness tolerance drives labor. Winter protection drives temporary heat and enclosure. Admixtures and curing compounds add to the price of the mix, but they also protect the work. A floor with steel fibers can cut the reinforcing labor and speed placement, while a floor with conventional mesh may cost less per yard but more per day.

Long-term cost depends on joints. A floor with wide joint spacing needs more reinforcement and careful detailing. A floor with narrower spacing needs more sawing and joint maintenance. We lay out the tradeoff and let the owner decide with a view to forklift traffic and maintenance. For tilt-up projects see our tilt-wall industrial buildings page, where the slab is also the casting bed.

Send us the loads and the flatness target

Tell us the building size, the racking or equipment loads and the flatness you need. We will prepare a slab plan with joint layout, a winter or wind strategy and a price, so the floor is ready when your racking arrives.

Common Questions

How flat does my warehouse floor need to be?

It depends on what runs on it. Standard racking and forklifts tolerate normal floor flatness. Narrow-aisle and high-bay racking systems need much tighter tolerances. Ask your racking supplier for the number before the pour, and we will price and plan the floor to meet it.

Why do floors curl at the joints?

Concrete dries faster at the surface than at the bottom, so the top shrinks more and the corners lift. Good mix design, curing, joint spacing and a uniform base reduce it. We also place and cure slabs to limit moisture loss from the top.

Can you pour a floor in winter?

Yes, if the building is enclosed and heated, the subgrade is thawed and the slab is protected until it gains strength. We schedule winter pours with extra care and budget for heat, because a poured slab that freezes early loses strength and durability.

Do I need a vapor barrier?

If the floor will receive moisture-sensitive flooring or coatings, or is in a humid process, yes. For a plain warehouse floor, many owners skip it. We follow the designer's specification and discuss tradeoffs. Placing concrete directly on a vapor barrier raises curling risk, which we manage with mix and curing.

How long before we can put racking on the floor?

Concrete gains strength over days, but full cure takes weeks. We can often open the floor for light foot traffic the next day and racking after a few days, subject to cylinder results and the designer's approval. Heavy equipment waits for test results.
