Antioch driveways and yards as we see them on jobs
Antioch is home base. I started this business here in 2023 after years of pouring and finishing next to my dad, and most of our calls come from homeowners in Antioch and the cities around it, plus some small business owners. Most of what we pour is flatwork, which is driveways, patios, walks and steps. In one week we might tear out a cracked driveway on a block near downtown, lay out a patio on a hillside street up toward Contra Loma, and form steps for a shop. The same work takes us west into Pittsburg and east to Oakley.
Lots here run from flat to steep, and plenty of yards slope toward the house or the street. That slope decides where the water goes, so on every job I work out the grade before anything else, because once the concrete is down you can't change it.
Concrete work we do on Antioch homes and businesses
Concrete driveway building
When a driveway has sunk at the garage or cracked across the middle, we tear it out, pack a new base and pour it sloped toward the street.
Concrete patio construction
Patios here get used most of the year, so we slope yours away from the house and lay out the joints around where you'll put the table.
Stamped concrete services
Stamped concrete gives a patio or entry the look of stone or brick, and we pack the base first, because a pattern can't hide settling.
Concrete sidewalk building
For a walk to the front door or along the side yard to the back gate, we keep it even underfoot and shedding water off to one side.
Garage floor concrete
A cracked garage floor can be cut out and repoured, with a slight fall toward the door so water off the car runs out instead of pooling.
Decorative concrete
Colored concrete, a pebble finish or a border can make a front walk or patio match the house, and I'll tell you which finishes stay comfortable under bare feet.
Concrete retaining walls
On sloped back yards a concrete retaining wall holds the hill back so you get flat ground to use, and we plan where the water behind it drains.
Concrete floor installation
For shops, sheds, workshops and room additions, we pour interior floors flat and level so walls, cabinets and equipment sit right on them.
Concrete pool decks
A pool deck takes bare feet, splash water and chemicals, so we give it a finish with grip and pitch it so water drains away from the pool.
Concrete steps construction
Crumbling or uneven front steps are a trip hazard, so we rebuild them with even rises and a landing that drains, tied into the walk below.
Slab foundation building
For a garage, an addition or an accessory building, we pour the slab foundation on a dug-out, packed base, square and level so the framing goes up true.
Foundation installation
When a new building needs a foundation, we lay it out from the plans, set the forms and steel, and pour it ready for framing.
Concrete parking lot building
Small business owners call us for parking areas and lots that carry daily traffic, so we build a heavier base and plan where the rainwater goes.
Concrete footings
Footings carry the weight of a wall, a patio cover or a deck post into firm ground, so we dig them to the size the plans call for.
Foundation raising
If part of a slab or house has dropped, I'll find out why it moved before we lift it, because lifting without fixing the cause won't hold.
Concrete cutting
We saw-cut concrete for a wider driveway, a new drain line, a door opening or a clean edge where the old slab meets the new one.

Working in Antioch: permits, licenses and what moves the price
The city's Building Services Division issues building permits here and inspects the work, so before we start I check what your job needs with the city, or with the county if your address falls outside city limits. If a permit is needed, we apply for it as your contractor, or help you file it yourself through the city's online permitting system, and we fit the review into the schedule before we set forms. Before you hire anyone, check that they hold a California contractor license and a current Antioch business license, which the city requires of every contractor and subcontractor working here. We're licensed and fully insured.
Getting concrete to the spot matters as much as the pour. A driveway open to the street lets the truck back right up, while a back yard patio behind a narrow side yard may need a pump or wheelbarrows, and that changes the cost. Price also moves with the size, how much old concrete and dirt has to come out, the thickness and steel, and the finish. The schedule turns on any permit, the weather and curing, the days a slab needs to harden before you use it, so the written estimate I send after measuring is where you get your own number. It's the same approach when we head out Highway 4 to Brentwood.
Why Antioch slabs sink, crack and hold water
Most sinking slabs we tear out have the same cause, a base that was raked level instead of dug out and packed. The subgrade, the ground the slab sits on, settles over the years, the slab goes down with it and water starts pooling in the low spot. That base is buried on day one and it's the first thing people cut from the budget, so if something has to give, I'd rather you pick a plain broom finish, the light texture that gives shoes and tires grip, than skimp underneath. We dig out, pack it firm and check which way the water will run, so your slab sheds water away from the house instead of toward it.
Concrete cracks, and anyone who tells you theirs won't isn't being straight with you. What we control is where. We cut control joints, straight grooves that give the slab a place to crack, while the concrete is still fresh, and we set rebar, the steel inside the slab that holds a crack tight instead of letting it spread.
What to expect when you hire us in Antioch
From your first call to the final walk-through, here's what happens and who you'll be dealing with along the way.
Call or send us a message
Call (925) 503-1201 any day from 6 AM to 11 PM, or use the form, and tell us what you want poured or replaced. We'll set a time for me to come out.
I measure and price it
I come out myself to look at the ground, where your water runs and how we'll get concrete to the spot, then send you a written estimate. You'll know the price before anything is booked, and it helps if you're home so we can talk through the layout.
We prep, pour and finish
Once you say go, we sort out anything the city or county needs, then my crew and I dig out, pack the base, set forms, pour and finish. If your job needs a permit, the review comes before we set forms, so we schedule the pour around it.
We walk the job together
I walk the finished job with you before we leave and go over how to treat the slab while it cures. Satisfaction guaranteed.
Questions about concrete work in Antioch
Call (925) 503-1201The cost comes down to the size, how much old concrete has to be broken out and hauled off, and how much digging and base the ground needs. Thickness, steel and the finish move it next, since a broom finish costs less than stamped or colored concrete. I don't quote concrete off a phone call, so I'll measure yours and send you a written price.
Maybe not, since the city lists most residential concrete flatwork, and retaining walls three feet tall or less, among the projects that don't need a building permit. That list says most, not all, so we check your address and your plan before we pour. You can see the list yourself on the city's Building Division page.
Yes, if the work reaches the public right-of-way, the strip along the street that usually includes the sidewalk and curb, the city's Engineering Division requires a separate encroachment permit, and that covers curb cuts and driveway changes. It's on top of anything the building side needs, so if your new driveway meets the street differently than the old one, we plan for it in the schedule. The city's building permit requirements page explains it.
A contractor needs a state license when the project needs a building permit, uses any other workers, or costs $1,000 or more in labor and materials, counted across every contract on the job. Nearly any driveway or patio passes that figure, so ask anyone you're comparing for their license number and look it up with the state board.
Longer than it takes before you can walk on it, because the slab keeps gaining strength as it cures and a car is the heaviest thing it carries. I give you the days for your slab when we finish, since the thickness, the mix and the weather that week all change it. Until then, park on the street and keep the drive taped off.
Most of the year works, because Antioch gets about 13 inches of rain in an average year, so we're usually watching the heat more than the rain. In warm weather the top can dry faster than the inside, which leaves a weak, dusty surface later, so we start pours early in the day and keep the slab damp while it cures. When rain is in the forecast, we move the pour rather than cover a fresh slab and hope.
