Concrete work in Antioch, from driveways to backyard walls
The short answer: C&K Pittsburg Concrete Company is a concrete contractor based in Pittsburg, CA, and Antioch is right next door, so it's a short drive for us. I come out to look at every job myself, and our crew pours driveways, patios, walkways, steps, walls and foundations for Antioch homes, rentals and small shops.
Most Antioch calls start with something you see every day. It's a driveway crack that keeps getting wider, a patio that's dropped at one corner, or water that sits by the garage door after it rains. We also hear from people who own rentals and small commercial lots here, where a broken walk or a rough parking area becomes a problem for tenants and customers. It's the same work we do in Pittsburg and Oakley, and we handle it the same careful way.
Lots here run from flat front yards to backyards that climb, and that changes the job. On a flat lot, most of the work is getting water to run away from the house. On a slope, a patio may need a step or a short wall to hold the ground behind it, so I look at the grade before we talk about finishes.
Why Antioch driveways and patios crack, sink and pool
Antioch gets only about 13 inches of rain a year on average, so the trouble isn't how much water falls but where it ends up. A slab that tips toward the house sends what rain there is to the foundation and the garage door, so before we pour, we check which way the yard drains and set the new slab to fall away from your walls.
Most of the sinking and cracking we're called about starts underneath. When the last crew raked the dirt level instead of digging it out and packing it, the slab settles as that loose dirt does, and no finish on top can save it. Hot summer afternoons cause their own problem, because concrete poured in midday heat can dry too fast and leave a weak, dusty top. So we dig down to firm ground, pack the subgrade, the layer the slab rests on, and schedule pours for the cooler part of the day.
Concrete services for Antioch homes, rentals and shops
Concrete driveway building
When your driveway is cracked, sunk at the garage or holding water, we tear it out, rebuild the base and pour one that drains to the street.
Concrete patio construction
A backyard patio for summer evenings, poured on a packed base and pitched away from the house so rain doesn't end up against the wall.
Stamped concrete services
If you want the look of stone or brick without pavers to weed and reset, stamped concrete presses that pattern into a single patio or walkway pour.
Concrete sidewalk building
When a front walk or side path has heaved, breaks at the edges or catches toes, we replace it with a level path nobody trips on.
Garage floor concrete
For a garage floor that's cracked, stained or uneven, we pour a new slab with a smooth finish that's easy to sweep and park on.
Decorative concrete
Color, exposed stone or a scored pattern on a driveway border or front walk, for when plain gray doesn't suit the house or the rest of the yard.
Concrete retaining walls
On a backyard that slopes, a concrete wall holds the hill back and gives you flat ground, with drainage behind it so water doesn't push it over.
Concrete floor installation
Interior slabs for additions, workshops and small commercial spaces, set on a compacted base with the right thickness for what will sit on them.
Concrete pool decks
Around a pool, the deck needs grip for wet feet and a slope that carries splash water away from the house, and we plan both before the pour.
Concrete steps construction
Front steps that have cracked, pulled away from the porch or rise at odd heights get rebuilt even, so nobody misses a step at your door.
Slab foundation building
For a new garage, ADU or addition, the slab foundation is the part you'll never see again, so the base and steel inside it get our closest attention.
Foundation installation
Footings and foundation walls for an addition or a building on a sloped lot, poured to the engineer's plans once the forms and steel are set.
Concrete parking lot building
For a shop, a rental property or a small business lot, we pour paving thick enough for daily traffic and graded so water doesn't sit where customers park.
Concrete footings
Concrete pads under porch posts, decks, walls and sheds, sized for the load so whatever sits on top doesn't lean or sink as the years go by.
Foundation raising
When part of the house has dropped and doors stick or floors slope, we lift and support it, bringing in an engineer when the job needs one.
Concrete cutting
We cut clean openings in old slabs for plumbing, doorways or a new walk, and we check for steel and pipe inside before the blade goes in.

Working in Antioch: permits, licenses and what moves the price
Permits for concrete work here go through the city's Building Services Division, which issues building permits and inspects the work. Its permit-exempt list includes most residential concrete flatwork, the driveways, patios and walks that sit flat on the ground, but most isn't all, so I check with the division early in planning and walk you through their answer. When a permit is needed, we pull it and plan the schedule around the city's review. Before you hire anyone, look the contractor up with the state licensing board, and ask whether they hold an Antioch business license, which the city requires of everyone doing business here, subcontractors included. We're fully licensed and insured, and I'd rather you check than take my word for it.
What moves the price here is mostly what's under and around the slab: how much old concrete comes out, how deep we dig for a solid base, how far the crew has to wheel concrete from the street, and whether the job touches the curb. After that come size and finish, because a broom finish, the light brushed texture that gives shoes and tires grip, costs less than stamping or color. The schedule turns on the weather and, when there's a permit, the city's review. Highway 4 is our usual way in from Pittsburg, the same road that takes us over to Concord, so getting a crew and a truck to your house is rarely what holds a job up. Your estimate spells out what's in the price and what isn't.
What happens when you call us about an Antioch job
Here's how a job goes from your first call to the final walk-through. I'm the one you'll see at the start and on the job, so you'll always know who to ask.
- Step 01
Call or send the form
Tell us what you're seeing, like a cracked driveway, a sunken patio corner or a new slab you've been planning, and where you are in Antioch. We'll set a time for me to come out.
- Step 02
I walk the site with you
I look at the old concrete, the grade and where the water runs, and I ask a lot of questions, because the hidden parts are what set the price. You get a written estimate that says what's in it and what isn't, so you know exactly what you're paying for.
- Step 03
We dig, set forms and pour
Our crew digs out and packs the base, sets the forms and the rebar, the steel that holds the slab together if it cracks, then pours and finishes it with me on the job. If a permit is needed, the pour waits for the city's review, and once it's down I'll tell you when you can walk on it and when the car can go back on, because curing, the slow hardening that gives concrete its strength, takes days.
- Step 04
Clean up and walk it together
We haul off the old concrete and leftover forms and leave the site swept. Then we walk the finished job with you and answer whatever's left.
Questions about concrete work in Antioch
How much does a new concrete driveway cost in Antioch?
I can't give you a fair price without seeing it, so your number comes in a written estimate after I walk the driveway and see what has to come out. If the budget is tight, I'd trim the finish before the base, because the base is buried on day one but it's what keeps the slab from sinking and cracking later. A plain broom finish over a well-packed base usually outlasts a fancy surface on raked dirt.
Do I need a separate permit to change my driveway at the curb in Antioch?
Yes, the city requires an encroachment permit from its Engineering Division for any work in the public right-of-way, the city's land along the street, and that includes curb cuts and driveway changes. It's separate from a building permit, and owners and contractors can apply for it online. If your new driveway reaches the street, we sort it out before the pour gets scheduled.
When does a contractor need a state license for concrete work in California?
A contractor needs a state license when the project needs a building permit, uses any other workers, or costs $1,000 or more. That $1,000 counts labor and materials together, across every contract on the project, so a bigger job split into small bills still counts as one. Below that line, with no permit and no employees, a license isn't required, as long as the person doesn't claim to be licensed.
What is the best way to build a retaining wall in a sloped Antioch backyard?
Start with the water, because a wall that can't drain gets pushed by the wet ground behind it, so we plan the drainage behind the wall before anything else. Height matters too, since the city lists retaining walls three feet tall or less as permit-exempt, and a taller one falls outside that exemption. If your slope needs more than that, I'll tell you early, along with whether an engineer should design it.
Can I pour a concrete shed pad in my Antioch backyard without a permit?
Not without checking first. The city's guidance says a portable shed may be exempt from a building permit if it's freestanding and movable, under 120 square feet, no taller than eight feet, with no plumbing or wiring and no permanent foundation. A poured pad could be read as that foundation, so before we pour one, we ask the building division how they'll treat your shed.
How do I keep a new patio in Antioch from cracking like the old one?
You keep it from sinking with a dug-out, packed base, and you control where it cracks with control joints, the shallow grooves cut across the slab so any crack forms in a straight line inside the groove. Joints cut late or skipped are why so many old patios crack in random places, so we cut them on time. I won't tell you a slab will never crack, but those two things keep it level and in one piece.
