Concrete contractor in Fremont, CA - driveways and patios on solid ground
Professional Union City Concrete is a concrete contractor based in Union City that pours driveways, patios, walkways, garage floors and slabs for homes across Fremont, CA, with careful prep under every slab and joints placed where they belong.
Houses and yards across Fremont
Fremont is a big city, and our jobs here run from the flat neighborhoods on the bay side to the sloped streets that climb toward the Mission Peak hills. Most calls are for houses on their own lots. Some are older homes with driveways and patios that have carried decades of use, and some are newer tract homes where the original concrete is starting to show its age. We also see shops and business properties. As a concrete contractor in Union City, CA, we're right next door, so Fremont feels as close to home as our work in Newark.
That range shapes the job. A flat lot near the bay usually comes down to getting water off the slab, while a sloped lot near the hills can need steps or a retaining wall before a patio makes sense.
What to know before a Fremont concrete job
Permits here come from the City of Fremont's Permit Center, the one-stop office where people get permits for construction projects. The city requires a building permit before anyone builds, alters, repairs or demolishes a structure, but its list doesn't settle whether a particular driveway or patio needs one, so that's the city's call and the Permit Center is where to ask. When your job does need a permit, we take care of the application and inspections and keep you informed, and that review has to clear before we pour. It's also worth asking any contractor you're considering whether they hold a current Fremont business tax registration, because the city won't schedule a final building inspection without one, and a permitted job can stall at the last step. We're licensed and fully insured.
What moves the price is mostly what you can't see on day one. The size and thickness of the slab matter, but so do how much soft ground has to come out and be replaced with a packed base, and whether the slope calls for steps or a wall. The schedule turns on the permit, if there is one, and on the wait before you can use the new slab. We plan jobs the same way in Hayward and Milpitas, and the written estimate I leave you lists what's included and what isn't, so you can see where your money goes.
Services in Fremont, CA
Concrete driveway building
Older Fremont driveways often crack or sink where the base settled under years of cars. We dig out the soft ground and pack a firm base before pouring.
Concrete patio construction
Fremont backyards often have an old patio that tips toward the house and holds water. Our concrete patio construction sets the slab to drain away from your walls.
Concrete sidewalk building
Tree roots along Fremont streets lift walkway panels until someone trips on the edge. We cut out lifted sections and pour new panels that sit flush.
Concrete retaining walls
Sloped lots toward the hills often need a wall to hold back soil. We build concrete walls on solid footings with drainage behind them.
Concrete steps construction
Front steps on older homes crack and pull away from the porch as the ground shifts. We break out old ones and form new steps of even height.
Garage floor concrete
Attached garages in Fremont tract homes take years of car weight and develop cracks and low spots. We pour a new floor that sheds water toward the door.
What Fremont ground asks of a new slab
Fremont sits close to the Hayward and Calaveras faults, and a city staff report on proposed building code changes carried forward the city's existing provisions for soils prone to liquefaction, where wet ground can lose its strength in a strong quake, and for corrosive soils, which wear away at buried steel. That's a point about the whole city, not a reading of your yard, but it's why I look at the ground before I price a job, and why footings, foundations and slabs with rebar, the steel that holds a slab together if it cracks, get planned around your site.
On older houses here, the slab we tear out usually tells the story. The dirt was raked level instead of dug out and packed, so the subgrade, the ground the slab sits on, settled and took the concrete with it. If the budget is tight, I'd rather spend it on a firm base and good drainage than on a fancier surface, because a finish can be redone later and a bad base can't be fixed without starting over.

Fremont concrete questions answered
How much does a new concrete driveway cost in Fremont?
The price of a Fremont driveway depends on its size and thickness, the base work your ground needs and the finish you pick, so I give you a written figure after seeing the site. Breaking out and hauling away an old driveway adds to it, and so does tight access that means more work by hand. A broom finish, the light brushed texture that gives tires and shoes grip, costs less than stamped or colored concrete, and that's usually the easiest place to save.
What comes first for exterior work on a Fremont home that's 50 years or older?
A historic evaluation comes first, because the city requires one before it issues permits for demolition, relocation or exterior changes on properties 50 years or older. The evaluation checks whether the property may have historic significance before anything is changed. If your house is that old and your concrete job needs a permit, ask the Permit Center early whether your work counts, since the evaluation can add time before we start.
Which building code applies to concrete work in Fremont now?
Fremont now follows the 2025 California Building Standards Code, which has applied since the start of 2026. If your project needs a permit, that's the code it's reviewed under, so we plan the footings, slab or foundation to it from the start.
What causes concrete driveways to crack in Fremont?
Most bad cracks come from ground settling under the slab, water running under its edges, or joints that were cut late or skipped. Concrete shrinks as it dries, so we cut control joints, shallow grooves that give the slab a planned place to crack, and set them where a crack does the least harm. A new slab can still show fine hairline cracks, but the firm base and drainage we talked about above, along with well-placed joints, make it far less likely to break up the way the old one did.
How long does a new concrete driveway or patio need to cure before I can use it in Fremont?
You can usually walk on new concrete well before you can drive on it, and I give you the dates for your slab when we walk the finished job. Curing is the stretch after the pour when concrete keeps gaining strength, and putting weight on it too soon can leave marks or cracks. The weather and the mix both affect it, which is why I set the dates for your job instead of quoting one rule.
Do I need a permit for a shed or gazebo on a concrete pad in Fremont?
Fremont requires a permit for residential accessory structures over 120 square feet, such as sheds, workshops, gazebos and cabanas, and smaller ones may be exempt. Every size still has to meet the city's zoning rules on use, placement and design, and any electrical, mechanical or plumbing work in the structure needs a permit no matter how small it is. Tell us the structure's size when you call, and if our part of the work needs a permit, we'll take care of the application and inspections.
