Concrete driveway building
A lot of Union City driveways are the original pour, and by now they've cracked across the middle or dropped at the garage where the dirt under them settled. We break out the old slab, dig down to firm ground, pack new base rock and pour a driveway that sheds water toward the street, with a broom finish, the light brushed texture that gives tires and shoes some grip.
Concrete patio construction
Backyard patios here often hold a puddle after every rain because they were poured dead level or tipped back toward the door. We set the new patio with a gentle fall away from the house and cut control joints, shallow grooves that give the slab a straight line to crack along instead of a random one.
Slab foundation building
When you're adding a garage, a room or a backyard unit, the slab under it has to match the plans, not a rule of thumb. Our slab foundation building covers the layout, the forms, the rebar, which is the steel inside that holds the slab together, and the pour.
Concrete retaining walls
Lots that climb toward the hills on the east side of the city often need a wall to hold a cut bank or level off a yard. We build concrete retaining walls on proper footings with drainage behind them, because a wall that traps water is the one that starts to lean.
Concrete steps construction
Front steps on older houses tend to pull away from the porch or tip as the ground under the bottom step settles. We tear them out, pack the ground underneath and pour new steps with even rises so nobody catches a toe.
Foundation raising
When a corner of a slab or a house has dropped, the cause is usually the ground under it, soil that got wet or was never packed. We find out why it moved before we lift it, so the fix deals with the water or the soil and not just the crack you can see.
Union City, CA properties and local conditions
The city's Building Division marks soils hazard zones east of Mission Boulevard and west of Union City Boulevard, and it's clear that those are broad areas, not a verdict on any one lot. What that tells me is that the ground under a slab here can't be taken on faith. When the base is raked level instead of dug out and packed, the slab settles right along with the dirt, so on every job we dig to firm ground, pack the base in layers and see what the soil is doing before we set a single form.
Water is the other half of it. Most of the sinking and pooling we get called about comes from a slab that falls toward the house or a downspout that empties onto the driveway, so I check where the water runs before anything is poured. If the budget gets tight, I'd rather you spend on the base and the drainage than on a fancy finish, because the base is buried on day one and it's the one part you can't fix later.
What to know about permits and licenses in Union City
In Union City, permits come through the city's Building Division, and whether your job needs one is their call, not ours. Their counter issues some permits right there and takes plan submittals for others, and when plans come back for changes and have to be sent in again, that's usually what stretches a schedule. When a job needs a permit, we handle the paperwork and inspections with you. Before you hire anyone, us included, you can check two things, a California contractor license and a Union City business license, and we're fully licensed and insured.
We come down from Hayward, so Union City is a short drive for our crew, and we work the same way here as we do in Fremont to the south and over the hill in Dublin. Your price mostly turns on the size of the slab, how much old concrete we break out and haul away, how much digging and base rock the ground needs, how close a truck can get and the finish you pick. The schedule turns on the permit, if there is one, and on curing, the wait while new concrete gains strength before you put weight on it, and the estimate gives you your own number.

Call us or send the form
Tell us what you've got, whether it's a cracked driveway, a new patio or a slab for an addition, and we'll set a time for me to come out. It helps if you're home for the visit so you can show me what's bothering you.
Walk the site and write it up
I look at the old slab, the grade, where the water runs and how close a truck can get, and I listen to what you want. The estimate spells out what goes into the base, the steel and the finish, so you know what you're paying for before you decide.
Line up permits and engineering
If your job needs a permit or drawings, we put that together and take it through the city with you. The Building Division counter is open Monday through Thursday, 9 a.m. to 5 p.m., and every other Friday from 9 a.m. to noon, so permit work moves on their days.
Prep, pour and walk through
Our crew digs out and packs the base, sets the forms and steel, pours, finishes and cuts the joints, with me running the work. When it's done, we walk the finished job with you and go over how long to stay off it while it cures.
Frequently asked questions
How do I know if my concrete contractor needs a Union City business license?
If they're working inside Union City, they need one. The city says its code requires a business license for every business and trade operating in Union City, and its list names contractors and out-of-town businesses working within city limits. You can read the rules on the city's business license page and ask any contractor you're weighing whether they hold one.
When does a concrete contractor need a California state license?
The Contractors State License Board requires a license when a job needs a building permit, uses any workers beyond the contractor, or comes to $1,000 or more in labor and materials across one or more contracts. The board only exempts small jobs that need no permit, use no employee labor and stay under that $1,000 mark in total. Most concrete work takes a crew, so ask to see a state license before you sign anything.
How much can a contractor ask for as a down payment in California?
The state board says a contractor can't ask for or take a down payment of more than $1,000 on a home improvement job, and on a smaller contract the limit is lower. It's a statewide rule, so it applies in Union City the same as anywhere in California. If someone wants a big check before any work starts, that's worth a second look.
What makes a concrete driveway cost more in Union City?
The ground under it and the finish on top are usually the biggest swings. A driveway that has already settled usually means the base failed, so we dig deeper and bring in more base rock, which costs more up front but is the work that keeps the new one from sinking the same way. Stamped or colored finishes run higher than a plain broom finish, and extra steel or thicker concrete where heavy trucks park adds some too.
How do I keep a new concrete patio from cracking?
Start with the base and the joints, because those decide where a slab cracks and how badly. Concrete shrinks as it cures, so we cut control joints early to give it straight lines to crack along, and we pour early in the day so the top doesn't dry out in midday heat and turn weak and dusty. With a packed base under it, cracks usually stay thin and stay put, though nobody can honestly promise concrete won't crack at all.
What building code does Union City use for a new slab foundation?
The Building Division lists the California Building Code and the state's residential code among the standards it follows, along with the energy, green building and other state codes. For a slab under a house, garage or addition, that means the plans set the thickness, footings and steel, and the inspections check the work against them. We build to the plans and the engineer's details, and we're there for the inspections.
About Union City, CA
Union City sits between Hayward and Fremont, and most of the work we see here is on single-family houses along tract streets, with townhomes, rentals and small businesses mixed in. A lot of those homes still have the driveways, walks and patios they were built with, and that's usually where the trouble shows up, a corner that dropped, a walk that tips toward the house or a patio that never drained right.
East of Mission Boulevard the streets climb toward the hills, and those lots bring cut banks, retaining walls and water running downhill across driveways. On the flatter ground the job is more about the base and getting water off a slab that has nowhere obvious to go, so in this city the ground decides how we build long before anyone picks a finish.
