Phoenix Concrete Co. installs and repairs residential and commercial concrete slabs throughout Phoenix. Our crews pour driveway slabs, patio slabs, floor slabs, industrial pads, and reinforced slabs on grade. We also provide decorative, exposed aggregate, stamped, stained, and polished concrete finishes for homes, retail spaces, offices, garages, warehouses, and pool decks. Projects can include slab leveling, resurfacing, coatings, demolition, and removal when existing concrete needs more than a new pour.
Caliche hardpan, expansive clay, and triple-digit surface temperatures make soil preparation and curing especially important in Phoenix. We assess the soil, drainage, and existing utility lines before selecting the base, reinforcement, and ready-mix design. Our crews follow American Concrete Institute mix and curing guidance, and structural work is permitted through Phoenix's Planning and Development Department. As licensed and insured concrete contractors, we provide a free concrete slab estimate after walking the property and testing the soil.
Residential pours can use standard rebar or welded wire mesh, while larger commercial work may call for heavier reinforcement and post-tensioned cable. We coordinate placement, finishing, jointing, curing, and final inspection around the slab's intended load and Phoenix heat.
Phoenix Concrete Co. installs and repairs concrete slabs across Phoenix and the surrounding metro, including Scottsdale, Tempe, Mesa, Glendale, and Chandler.
A concrete slab is a flat structural surface poured over a prepared base for uses such as driveways, patios, garage floors, warehouse floors, foundations, and equipment pads. Its thickness, reinforcement, joint layout, and concrete strength should match the loads and site conditions it will face.
In Phoenix, slab performance starts below the concrete. Caliche may need over-excavation, expansive soil may need removal, and the aggregate base must be compacted in engineered lifts before a minimum 4-inch reinforced residential slab is placed.
The finished surface can be broomed for traction, troweled for interior use, exposed to reveal aggregate, stamped, stained, polished, or protected with an epoxy coating. Drainage slope, vapor barriers, reinforcement, curing, and joint placement are coordinated with the final application.
A slab designed for its soil, load, drainage, and finish can deliver long service life with fewer avoidable cracks, settlement problems, and surface defects. Professional planning also keeps the base, reinforcement, concrete mix, joints, and cure working as one system.
We build, finish, repair, and remove concrete for residential, commercial, and industrial properties. Each service is planned around Phoenix soil, drainage, heat, the intended load, and the surface appearance the project requires.
Residential work includes driveway slabs, patio slabs, garage floors, shed and equipment pads, pool surrounds, and reinforced slabs on grade. We grade for drainage, add vapor barriers where concrete meets living space, and match the finish to the home's use and design.

Warehouse and industrial slabs around the Sky Harbor logistics corridor and West Valley distribution hubs are built for forklift traffic, racking loads, and constant wheel loading. These pours are often 6 inches or thicker, with heavier reinforcement and joint layouts set by structural engineering requirements.
Request Estimate
Decorative options include earth-tone stained slabs, exposed aggregate for pool surrounds, stamped surfaces that mimic flagstone or travertine, and polished interior floors. These finishes are used across Phoenix neighborhoods from Arcadia to Ahwatukee and are selected with traction, exposure, and maintenance in mind.
Request Estimate
Settled or worn concrete may be a candidate for slabjacking, mudjacking, an overlay, or resurfacing instead of full replacement. We evaluate driveways, garages, warehouses, and pool decks to determine whether leveling or a new surface can address the condition.
Request Estimate
Polished concrete and epoxy coatings create finished surfaces for garages, retail buildouts, offices, and warehouses. Floor-slab planning accounts for flatness tolerances, ADA-compliant transitions, cure timing, and the needs of the final flooring or coating system.
Request Estimate
Our concrete work also includes countertops, custom sinks, tables, firepits, and precast products. When an existing slab cannot be repaired or conflicts with the new design, we provide concrete demolition and removal as part of project preparation.
Request EstimateThe right slab configuration depends on whether the surface supports a home, vehicle, tenant space, warehouse operation, or decorative outdoor area. Soil conditions, access, load, drainage, reinforcement, finish, and future flooring all shape the final specification.
Residential slabs are configured for the property's use, drainage, soil, and connection to living space. Base preparation and reinforcement are adjusted for caliche and expansive clay before the pour begins.
Commercial slabs are designed around structural loads, repetitive traffic, tenant-improvement schedules, and the specified finish. The project engineer's requirements guide thickness, reinforcement, joints, and when the slab can accept loads.
Surface finish changes the slab's traction, appearance, and readiness for interior or exterior use. We select the finishing method during planning so the crew can prepare forms, color, aggregate, timing, and protection correctly.
Concrete mix designs typically range from 3,000 to 4,500 psi based on the application, water-cement ratio, abrasion demands, and specified admixtures. Reinforcement and ready-mix requirements are selected together so the slab performs as designed.
Existing slabs can be evaluated for leveling, surface restoration, protective treatments, or removal. The right approach depends on settlement, surface wear, the slab's intended use, and whether the underlying base remains suitable.
Choosing a slab approach starts with the property's soil, drainage, access, use, and expected loads. From there, we match excavation, base preparation, reinforcement, mix strength, joints, finish, curing, and any coating or sealer to the project rather than applying one specification to every pour.
We check caliche depth, expansive soil, drainage patterns, and utility lines before excavation. Where required, crews remove unstable material and compact a 4- to 6-inch aggregate base course to create a stable, well-draining foundation.
We plan ready-mix delivery, placement, finishing, and curing around Phoenix heat and wind. Early-morning summer pours, evaporation retardants when conditions threaten the surface, curing compound, and an initial UV sealer on exposed work help protect finish quality.
Phoenix Concrete Co. carries an Arizona Registrar of Contractors license and standard liability coverage for residential and commercial projects. We pull permits through Phoenix's Planning and Development Department for structural work and review commercial designs against City of Phoenix and Maricopa County requirements.
Our process documents base compaction, reinforcement placement, final finish, slope, and joint placement before the walkthrough. We coordinate engineered requirements on structural and commercial work, explain the factors driving price, and provide a free itemized estimate after the site visit.
Request Free EstimateCaliche does not compact like ordinary soil, so pouring over an unprepared layer can leave uneven support beneath the slab. When sub-base work is skipped, cracking and settlement can appear within the first five years; some poorly built slabs crack in as little as three years.
Expansive Phoenix-area clay moves as moisture conditions change, which can shift slabs and open cracks. Over-excavation, a compacted base, suitable reinforcement, and post-tensioning on qualifying projects help the design manage that movement.
Heat and wind can pull moisture from fresh concrete so quickly that plastic shrinkage cracks form within hours of a summer pour. Placement timing, evaporation control, finishing discipline, and immediate curing protection are essential to surface quality.
A slab with the wrong slope can direct water toward a building or trap it against the concrete. Slabs beside living space or under moisture-sensitive flooring may also need a vapor barrier included in the original design.
Reinforcement that is too light, poorly spaced, or displaced during the pour cannot provide consistent crack control. The slab's load and soil conditions determine whether rebar, welded wire mesh, heavier schedules, or post-tensioned cable is appropriate.
Forklifts, racks, loading areas, and repetitive wheel traffic concentrate forces that residential slab details were not designed to carry. Commercial thickness, reinforcement, strength, and joint layouts must follow the structural engineer's load requirements.
Every slab moves through site evaluation, base preparation, forming, reinforcement, placement, finishing, curing, and inspection. The sequence is adjusted for the property's soil, access, load, finish, and Phoenix weather.
We visit the property to check caliche depth, expansive soil, drainage patterns, access, and existing utility lines. These findings guide the slab plan, reinforcement approach, excavation, and itemized estimate.
Crews excavate to design depth, remove unstable native soil where required, and place the aggregate base in compacted lifts. Forms are then set to grade so the completed slab drains toward the street or landscape beds as planned.
We set forms to the required dimensions and install rebar or welded wire mesh at the specified spacing. Post-tensioning cable is added on qualifying commercial, multi-family, and residential designs.
The ready-mix specification is matched to the slab's use, structural requirements, abrasion exposure, water-cement ratio, and admixtures. Truck timing is coordinated so concrete can be placed, screeded, and floated without avoidable delays in the heat.
Crews apply the selected broom, trowel, exposed aggregate, stamped, stained, or polished finish and confirm the required slope. Control joints are placed to manage shrinkage cracking, with the layout adjusted to slab thickness and design.
We apply curing compound and the initial UV sealer on exposed slabs, then inspect the surface, slope, and joint placement before the final walkthrough. On larger commercial pours, cylinder testing confirms strength gain before the designed load is applied.

Call About Concrete SlabsA 40x60 slab covers 2,400 square feet and typically falls between $16,800 and $28,800 at the Phoenix market range of $7 to $12 per square foot. Thickness, reinforcement, finish, and the amount of excavation or base preparation required by the site's caliche affect the final price. A pad of this scale may also require engineered reinforcement rather than basic wire mesh.
A 10x10 slab covers 100 square feet and averages around $620 installed in the Phoenix area. That baseline reflects a standard 4-inch reinforced slab on grade with a basic finish. Stamped or stained finishes and additional excavation through caliche raise the price.
A 30x30 slab covers 900 square feet and averages roughly $5,578 in the Phoenix market. This size can fit a two-to-three-car garage, workshop, or small commercial pad. Reinforcement, expansive clay or caliche excavation, and the selected finish can change the estimate.
A 20x20 slab covers 400 square feet and averages around $2,479 installed for standard reinforced slab-on-grade work. It is a common size for a single-car garage, carport, or mid-size patio. Site access, drainage grading, and decorative finishes can move the final number up or down.
A 4-inch residential slab can use welded wire mesh or rebar, but rebar holds its position more consistently during a pour and offers dependable crack control in expansive Phoenix soil. Driveways, garages, and patios that carry vehicles often use rebar on 12- to 18-inch centers, depending on the design. A light-duty pad may qualify for mesh after the soil and intended load are evaluated.
The 1/2/3 rule is a general concrete jointing guideline in which control-joint spacing is roughly two to three times the slab thickness in feet. For a standard 4-inch slab, joints commonly fall about 8 to 12 feet apart. The actual layout should also follow ACI guidance and account for Phoenix's fast summer evaporation.
A slab should sit on a compacted aggregate base course, usually 4 to 6 inches of crushed stone, to provide drainage and uniform support. In Phoenix, caliche or expansive clay may need over-excavation before the base is placed. A vapor barrier is also used beside living space or under moisture-sensitive flooring.
Phoenix slab pricing runs roughly $7 to $12 per square foot depending on thickness, reinforcement, base conditions, and finish. Basic 4-inch reinforced work is priced near $6.11 per square foot, while typical full driveway or patio pours range from roughly $2,979 to $5,958 with materials and labor. Additional line items can include stakes at $80-$200, curing compound at $60-$160, and a first UV sealer application at $80-$200.
Concrete costs more per square foot at installation, but a properly built residential slab can last 25 to 30 years in this climate. Asphalt surfaces exposed to the same heat cycles typically last 12 to 18 years. That longer service life can make concrete the lower lifetime-cost option.
A residential slab on grade is commonly a minimum of 4 inches, with reinforcement selected for the soil and load. Warehouse and industrial slabs are often 6 inches or thicker to handle forklifts, racks, and repetitive wheel traffic. Commercial dimensions and reinforcement should follow the project's structural engineer.
Options include broom, exposed aggregate, stamped, stained, polished, and epoxy-coated surfaces. Stamped concrete can mimic flagstone or travertine, while earth-tone stains and exposed aggregate work well with desert landscaping and pool areas. The final choice should account for traction, exposure, and maintenance.
Some settled slabs can be raised with slabjacking or mudjacking, while worn surfaces may qualify for an overlay, resurfacing, or epoxy coating. Driveways, garages, warehouses, and pool decks are evaluated for these options. If the slab or base is not suitable for repair, demolition and removal may be the better approach.
Triple-digit surface temperatures and wind accelerate evaporation, and plastic shrinkage cracking can develop within hours of a summer pour. Early-morning placement, evaporation retardants when needed, prompt curing compound, and careful finishing help protect the surface. Exposed slabs also receive an initial UV sealer application.
