Concrete Garage Floors in North Phoenix, AZ
Concrete Floors
Garage and shop floors that hold up.
Interior floors live by different rules than outdoor flatwork. They need to be flat, carry point loads like a jack stand or a lift, and stand up to whatever drips off the car. We handle tear-out, base, vapor barrier, joints and a finish that suits the room, from smooth trowel to epoxy.

What Phoenix asks of a floor
A hot-weather pour, indoors too
A garage slab poured in summer is still a hot-weather pour. Industry practice limits fresh concrete to 95°F at delivery unless a hotter mix is proven, so the pour is scheduled and the mix adjusted for the day.
Coatings need prep
Epoxy and flake coatings resist oil and stains and clean with a mop, but they need a clean, sound, prepared slab to bond to. That prep is most of the job, and it is why a coating goes on after the new slab has cured.

Straightforward or decorative
Broom finish
Fine ridges for grip when it’s wet from a storm or the sprinklers. The standard for driveways and walks.
Integral color
Color mixed through the concrete, so chips don’t show grey and the sun doesn’t fade it.
Smooth trowel
Dense and flat for garage floors, shops and courts.
Sealed
A UV-resistant sealer against water, stains and sun fade, renewed every few years.
A floor on caliche is a different job than one on wash sand
The Valley has four kinds of ground, and each one changes how we prepare the base, reinforce the slab and handle water. Your community page has the specifics.
Caliche desert floor
Dig to firm ground, break out caliche that sits high in the base and haul it off the site, bring in aggregate base compacted in lifts, and slope the slab and the grade so roof and sprinkler water run away from it and off the hardpan.
River and wash alluvium
Compaction done in lifts at the right moisture, with loose or soft soil dug out and replaced, a thicker section anywhere a truck, trailer or RV will park, and grading that keeps runoff off the slab and out from under it. Washes and drainage easements stay open.
Expansive clay pockets
Remove the soft and organic soil, bring in compacted aggregate base, set rebar on chairs, and keep the moisture under the slab steady: drainage away from it, and turf and drip lines held back from its edges.
Desert foothills and rock
Excavation into the rock or hardpan, a thicker compacted base where the support is uneven, drainage that catches runoff above the slab and carries it around, and engineered retaining walls where the grade is cut. Walls on hillside lots often need a permit, and each city and town has its own rules, so we check yours.
