San Tan Valley homes and the concrete around them
Most of what we pour in San Tan Valley goes around newer subdivision homes, where people have lived with the builder's concrete for a few years and now want more of it. We're a concrete contractor based in Mesa, AZ, and the calls we get here are usually for a wider driveway, a bigger back patio, a pool deck, a walk to the side gate or an RV pad, along with footings and slabs for builders putting up new structures as the town fills in.
Because the houses are newer, the slab you want gone usually went in with the subdivision, and nobody can tell how well that ground was packed until the old concrete is out. That's why the estimate spells out the base work, and if the ground under there is worse than it looked, I'll tell you before we pour, not after.
Concrete work we do for San Tan Valley homes
- Concrete driveway building
Builder driveways here are often the first slab owners widen or replace, and we dig out and pack the base so the new one doesn't settle.
- Concrete patio construction
Many homes here came with a small back patio, and we extend or replace it with a slab sloped away from the house.
- Stamped concrete services
Stamped concrete gives a patio or entry the look of stone or pavers, pressed into the slab while it's still soft, for owners who want more than gray.
- Concrete sidewalk building
A poured walk to the side gate gives you a dry path after a storm, and we slope it so water runs off instead of toward the house.
- Garage floor concrete
When a garage floor has cracked or sunk at the door, we cut out the bad section and pour back a slab that carries your car's weight.
- Decorative concrete
Colored and exposed-aggregate finishes dress up an entry or courtyard, and in the desert sun we steer you toward lighter colors that stay cooler underfoot.
- Concrete retaining walls
Where a yard changes grade at a property line or drainage channel, a retaining wall holds the dirt back, and we plan where the water goes.
- Concrete floor installation
Casitas, workshops and room additions need an interior floor slab that's flat and level, and we set the base and forms so finish flooring goes down clean.
- Concrete pool decks
Pool decks here take full sun and bare feet, so we finish them for grip and slope them so water drains away from the pool and house.
- Concrete steps construction
Front and back steps can settle away from the slab they meet, and we pour new ones with even step heights, tied in so they stay put.
- Slab foundation building
For new casitas, detached garages and additions, we pour the slab foundation to the plans, with the base packed and the steel set before the truck comes.
- Foundation installation
Small builders and property owners call us for foundations on new structures here, and we form, set the steel and pour to the engineer's drawings.
- Concrete parking lot building
Shops and offices along the main roads need lots that carry delivery trucks and drain to the right spot, so we pour thicker slabs with a planned slope.
- Concrete footings
Block walls, pergolas and shade structures sit on footings, the buried concrete that spreads their weight, and we dig them to the depth the plans call for.
- Foundation raising
When a slab or footing has dropped, we look at why before we lift it, because raising it without fixing the cause usually means it sinks again.
- Concrete cutting
We saw-cut openings for doors and plumbing runs, and cut out a cracked driveway section so it can be replaced without tearing out the whole slab.

Call (480) 645-9450Working in San Tan Valley while the county handles permits
San Tan Valley is a new town, and for now Pinal County still issues building permits here, once the town has signed off that the work fits its zoning. A job that needs a permit waits on both offices before we can set forms, so at the estimate we settle with you whether yours needs one and who pulls it, and we work to the inspections the county sets. We're licensed and fully insured, and if you're not sure about any of it, ask me and we'll go over it together.
What moves the price here is the size and thickness of the slab, how much old concrete comes out first and how much base work the ground needs, and your written estimate breaks those out so you can see what you're paying for. The schedule turns on the permit, if there is one, and the weather, so we line up pours for early morning with the trucks coming in off Hunt Highway, the same way we run jobs up in Gilbert and Chandler.
Storm water and desert heat on San Tan Valley slabs
Rain doesn't come often here, but when a storm does, the water that lands on your slab has to go somewhere. A drainage study covering the town found that in a 100-year storm, up to 222 structures in its study area could have as much as six inches of water ponding right against them, and a patio or driveway that falls toward the house makes that worse by sending runoff to your foundation. Before we form anything, I look at where water runs on your lot now, and we slope the new slab to carry it away from the house.
The sun is the other thing every slab here fights. Concrete poured in the midday heat dries too fast on top and turns weak and dusty later, so we pour early, keep the slab damp while it cures, which is the slow hardening that gives it strength, and cut control joints, shallow grooves that tell the slab where to crack, as soon as it can take the saw.
What to expect from your San Tan Valley concrete job
Here's how a job goes from your first call to the final walk-through, so you know who you'll see and what you get along the way.
Call us and set a visit
Call (480) 645-9450 or send the form, and I'll set up a time to come out, look at the site and hear what you want. It helps if you're home for it, so you can show me where water sits after a storm.
Walk the site with me
I look at the ground and the old concrete, then write you an estimate that spells out the prep, the pour and any removal, so you can see what the price covers before you decide. If your job needs a permit, we settle who pulls it right then, and the start date waits until it's issued.
We prep, pour and finish
Once you're ready, we schedule around the weather, and our crew digs out and packs the subgrade, the ground the slab sits on, then sets forms and rebar, the steel that keeps a crack from spreading apart. We pour and give it a broom finish, a brushed texture so it isn't slick, and I check in on site through the job.
Walk the finished job together
We walk the finished job with you and go over how long to stay off it, since new concrete takes foot traffic well before it's ready for a car. Your satisfaction, guaranteed.
Questions about concrete work in San Tan Valley
Who issues building permits in San Tan Valley right now?
Pinal County issues building permits for qualifying San Tan Valley projects during a transition expected to run through December 31, 2026, and the town expects to take over permitting on or before January 1, 2027. Applications go to Pinal County, and each one now needs the property owner's authorization, so you'll be asked for it even when we pull the permit. Applications filed on or after January 1 follow the town's newer building codes, so when you file can change what the permit asks for.
Does a small shed in San Tan Valley need a building permit?
A one-story detached storage shed or playhouse of 200 square feet or less, with walls no taller than 10 feet and set in an approved location, is exempt from a building permit under a Pinal County bulletin. That exemption is about the shed, and the county notes that work without a building permit can still need an electrical, plumbing or mechanical permit or other agency approvals. Bring up the shed pad at the estimate and we'll go over it with you before anything gets poured.
How do I know if my San Tan Valley home is in a flood zone?
The town checks whether your project falls in a FEMA flood hazard area, and in local reporting on a drainage study, the Queen Creek Wash was named as the only federally mapped floodplain in San Tan Valley. If your project is in one, the town sends you to the Pinal County Flood Control District for a floodplain clearance or floodplain use permit, and a copy has to go in with the building permit application.
What adds to the cost of a concrete driveway in San Tan Valley?
The biggest swings usually come from what has to be torn out first and how much base work the ground needs, more than from the pour itself. If the job needs a permit, permit and inspection fees are paid straight to Pinal County, plus a processing fee while the county handles permits for the town. If you need to trim, I'd drop a fancy finish before I'd skimp on the base, because the base is what keeps the slab from settling and you can't fix it later without tearing out the concrete.
What causes concrete driveways to crack in San Tan Valley?
Most cracking we see comes from a base that was raked level instead of dug out and packed, joints that were cut late or skipped, and concrete poured in the heat of the day. Concrete almost always cracks some as it shrinks, so the joints give it a straight place to do it, and a packed base keeps the slab from sinking with the dirt under it. We handle all three on our jobs, which is why we start with the ground and not the finish.
How do I fix a patio that pools water against my house in San Tan Valley?
Usually by cutting out the section that tips toward the house and pouring it back with a fall that carries water away, because a patch or coating on top doesn't change where the water runs. Rain is light here, about 7.22 inches a year on average for the Phoenix area, so a bad slope can hide for months until a storm shows you where it goes. At the estimate I'll look at how water moves across your whole yard before we cut anything.
