Union City concrete work, from the hills to the flats
Union City sits between our home base in Fremont and Hayward. Most of our calls here come from single-family houses with a driveway out front and a patio out back, along with townhomes, apartment buildings and the shops and offices along the main roads. A lot of the concrete on these streets has been down since the neighborhoods went in, so we see plenty of driveways cracked across the middle, walks lifted by tree roots and patios that have settled toward the house.
The ground changes the job from one side of the city to the other. Lots in the hills east of Mission Boulevard mean steeper driveways, more steps and sometimes a retaining wall, while flatter lots to the west usually come down to how wide the slab runs and where its water goes.
Concrete services we offer in Union City
Concrete driveway building
Most Union City driveways we see are cracked or lifting at the street end. We tear out the old slab, dig and pack a new base, then pour.
Concrete patio construction
Backyard patios here are often small and tight to the house, so we set the slope to carry water away from your foundation, not toward it.
Stamped concrete services
Stamped concrete gives a front walk or patio the look of stone or brick, which suits a lot of Union City entries. We seal it to wear well.
Concrete sidewalk building
Union City walks to the door or along the street heave and crack with age. We replace them sloped to drain and flush with what's around them.
Garage floor concrete
Garage floors in older Union City houses are often cracked, stained or sunk in spots. We pour a new slab that holds a car and a workbench.
Decorative concrete
Colored concrete, exposed stone and borders can dress up a plain Union City front yard without changing the layout. We match the finish to your house and street.
Concrete retaining walls
On sloped lots east of Mission Boulevard, a concrete retaining wall holds back the hill and gives you a flat strip of yard you can use.
Concrete floor installation
For additions, workshops and commercial spaces in Union City, we pour interior concrete floors flat and finished smooth enough to take tile, coating or traffic.
Concrete pool decks
Pool decks here take sun, wet feet and splashing all summer. We pour them with a textured finish for grip and slope them away from the pool.
Concrete steps construction
Raised entries and split-level homes in Union City often have front steps that have cracked or pulled away from the house. We rebuild them even and solid.
Slab foundation building
When you're adding a room, backyard unit or garage, the slab under it decides how the building holds up. We dig, pack and set steel before pouring.
Foundation installation
New foundations for additions and rebuilds on Union City lots start with footings dug to firm ground, so the walls above have something solid to sit on.
Concrete parking lot building
For shops, offices and apartment lots along Union City's main roads, we pour concrete parking areas built for daily traffic and sloped to drain to the right spots.
Concrete footings
Decks, patio covers and fences in Union City backyards need concrete footings under them. We dig them to the depth the plans call for and pour them clean.
Foundation raising
If a corner of your Union City house or a slab has dropped and doors stick or floors slope, we look at why it moved before we lift it.
Concrete cutting
We saw-cut old driveways for removal, open slabs for plumbing repairs and cut trenches, with water on the blade to keep dust down on close-set Union City streets.

Working in Union City: permits, licenses and what moves the price
Whether a driveway, patio or slab in Union City needs a permit is the call of the city's Building Division, so when it isn't clear I check with them for your address before we start. A job that has to go through plan review waits on the city before we can break ground, and that's usually the first thing that moves a start date. Before you hire anyone here, ask to see two things, a California contractor license and a Union City business license, and the questions below cover when each one applies.
I learned concrete on a city crew, pouring sidewalks, curbs and driveway approaches next to inspectors, and I started this business in Fremont in 2020 to bring that same care to homeowners. The price here moves with the size of the slab, whether old concrete has to be broken out and hauled off, how much soft dirt comes out under it, the thickness and steel it needs, the finish you choose and how easy it is to get a truck to the pour. The schedule turns on the permit, the tear-out and the days the concrete needs before you use it, and your written estimate lays all of that out. Trucks reach most jobs here off Mission Boulevard or Union City Boulevard, and on tighter streets we plan where the truck sits before pour day, the same as we do in Fremont and Newark. We're licensed and insured, with satisfaction guaranteed on every job.
Why Union City slabs crack, sink and hold water
The Building Division marks soils hazard zones east of Mission Boulevard and west of Union City Boulevard. Those are general areas and say nothing about your lot in particular, but they're a good reason I look at the ground before I price anything. The subgrade, the dirt the slab sits on, decides how the concrete holds up, so we dig out soft or loose soil, pack in a base and set rebar, steel bars that hold the slab together if it does crack. That's the part nobody sees once it's poured, and it's the part I won't cut.
Most of the cracked or sinking slabs we tear out had the same problems, a base that was raked level instead of dug out and packed, water running toward the house and no control joints. Concrete shrinks as it hardens, so we cut control joints, straight grooves that give the crack a planned place to go, and we slope the slab to carry water away from your house.
How a concrete job runs when you call us in Union City
Here's how a job goes from your first call to the walk-through, so you know who you'll talk to and when anything gets poured.
Call or send us a note
Call (341) 201-0945 or use the form and tell us about the slab, and we'll get back to you to set a time for me to come out. You don't need plans or measurements to start.
I look at your site
I walk the site with you, check the ground, the old concrete and where the water runs, and listen to what you want. You get a written estimate that spells out what's included, so you can see what you're paying for before anything is poured.
We pull permits and pour
Once you say go, we pull any permit the job needs and set up the inspections, working around the Building Division's counter hours of Monday through Thursday, 9 a.m. to 5 p.m., and every other Friday from 9 a.m. to noon. Then our crew digs out, packs the base and pours, with me on site running it.
Walk the finished job together
When the pour is done, I walk the job with you and go over how to treat it while it hardens. We clean up and leave the street, gutter and sidewalk the way we found them.
Questions about concrete work in Union City
Who handles permits for concrete work in Union City?
The city's Building Division handles permits in Union City, and its counter takes over-the-counter permits along with plans and resubmittals for jobs that need review. When your concrete job needs a permit, we deal with the counter, the inspections and the inspector for you, as the steps above lay out.
Does a concrete contractor need a Union City business license?
Yes, the city requires a business license for every business and trade working in Union City, and its list names contractors and out-of-town businesses working inside city limits. That includes a Fremont company like ours, so it's fair to ask any contractor you're weighing about it.
How do I know if my concrete contractor needs a California license?
A contractor needs a license from the Contractors State License Board when the job needs a building permit, uses any additional workers, or totals $1,000 or more in labor and materials. The board says a job may be exempt only when it needs no permit, uses no employees and comes in under $1,000 all in. Ask for the license before you sign anything.
How much does a concrete driveway cost in Union City?
A Union City driveway's price comes down to its size, the tear-out, the base work under it and the finish, so your number comes from the written estimate I put together at your house. A broom finish, a light dragged texture that gives shoes and tires grip, costs less than stamped or colored concrete, while a thicker slab with more steel costs more. If the budget's tight, I'd rather you save on the finish than the base, because the base is buried on day one and it's the one thing you can't fix later without tearing the whole slab out.
How long does a new concrete driveway take before I can drive on it?
You can walk on new concrete well before you can drive on it, because it keeps gaining strength for days after the pour, a wait called curing. I'll tell you on the walk-through when your slab is ready for feet and when it's ready for cars, since the mix and the conditions on pour day change it. We'll also plan around where you'll park while the driveway is out.
What building codes does Union City use for concrete work?
The Building Division lists the California Building Code and the California Residential Code among the standards it follows, along with the state's electrical, mechanical, plumbing, energy, fire and green building codes. When your driveway, patio or other flatwork, the trade's word for flat slabs, goes under a permit, we build it to what the permit and those codes call for.
