D&T Diamond Bar Concrete pours driveways, patios, steps and slabs for homeowners in Walnut, CA. We're based nearby in Diamond Bar, and we dig out and pack the ground under every slab before we pour.
Concrete work in Walnutfrom a crew just next door
We're based in Diamond Bar and pour the same driveways, patios and steps in Walnut that we do in San Dimas and West Covina. Many homes here sit on a slope, so where the water runs matters as much as the finish.
What moves the price is the size of the slab, how much old concrete comes out, how deep the base has to go and whether you want a stamped finish. The schedule turns on the permit question, the weather and curing, the wait before a slab can take weight.
Call (909) 760-1399 or send us the form, and I'll come out, measure and write up what's in the price.
Concrete we pour in Walnutfrom driveways down to footings
Most Walnut calls are for driveways, patios and steps, but we also handle walls, foundations and small business lots when a job calls for them.
- Concrete driveway building Sloped driveways need a packed base and a fall away from the garage, so water heads for the street.
- Concrete patio construction Backyard patios pitched away from the house, so rain runs into the yard and not under your back door.
- Stamped concrete services Stamped patterns for front walks and patios, laid over the same dug-out, packed base as plain concrete.
- Concrete sidewalk building Side-yard and front walks rebuilt where old sections have lifted or sunk into a trip hazard.
- Garage floor concrete When cracks and chipping have spread across the garage, we replace the slab and cut control joints, grooves that tell cracks where to run.
- Decorative concrete Colored and textured concrete for entries and courtyards where a plain gray slab doesn't suit the house.
- Concrete retaining walls On a sloped yard, a concrete wall holds back the hill so a patio or play area can sit level.
- Concrete floor installation Interior and shop floors poured over a checked, compacted subgrade, the ground the slab rests on.
- Concrete pool decks Pool decks with a textured top for bare feet and a pitch that sends splash water to the drains.
- Concrete steps construction Where a house sits above the street or the yard, we build front and back steps with even risers.
- Slab foundation building Slabs for additions, sheds and ADUs, with rebar, the steel inside that holds cracks tight.
- Foundation installation New foundations for additions and outbuildings, dug to firm ground before any concrete goes in.
- Concrete parking lot building Small business owners call us for lots built to carry cars and delivery trucks every day.
- Concrete footings Footings for patio covers, walls and posts, set on packed soil so they stay where we put them.
- Foundation raising If a slab or small foundation has sunk on one side, we find out why before we talk about lifting it.
- Concrete cutting Clean saw cuts for doorways, utility trenches, or taking out one bad section instead of the whole slab.
Why Walnut calls usstraight answers before the pour
I started our business in 2023 after learning driveway and patio work around Diamond Bar, and I explain each step the way I'd want it explained. Satisfaction guaranteed on every job.
Licensed in California, insured on every job
California's contractors board requires a license for work that needs a building permit, uses employees or costs $1,000 or more, counting labor and materials. We're fully licensed and insured.
The owner works the job
I work alongside our crew on the job itself, so the person who quoted your slab is the one checking the base and the forms.
The base comes before the finish
If the budget's tight, I'd cut a fancy finish before I'd cut the base, because a nice top on soft dirt cracks and sinks with it.
Water checked before we form
We look at where water runs on your lot and set the slab to fall away from the house, so it doesn't pool against your foundation.
You'll hear if you don't need it
I'd rather lose a job than sell you work you don't need, so if cutting out one bad section will do, that's what I'll tell you.
From your call to cleanupwith one person you can reach
You talk to me from the first look to the last walkthrough, and the estimate is free and written out, so you know what you're paying for before anything gets dug up.
You call or message us
Call (909) 760-1399 or use the form and tell us what's going on, like a cracked driveway or a patio that pools water. We get back to you.
I come out and measure
I look at the job myself and measure it. Your estimate spells out what's in the price and what isn't, like whether the old concrete gets hauled off.
Permit check, then the pour
A permit is the city's call, so we check with the local building office before setting a date and handle the paperwork with you if one's needed. Then I'm on site from forming to cleanup.
We walk it together
Once the forms are off and the site's clean, we walk the new concrete together, and I tell you when it's ready to walk on and when it's ready for the car.
What Walnut lots ask of concreteslopes, sun and tired old slabs
These are the conditions we run into most on Walnut jobs, and what we do about each one.
Steep driveways
On a steep drive we shape the pitch so runoff heads to the street and give it a broom finish, a light texture that gives tires grip.
Hot afternoons on pour day
Concrete poured in midday heat can end up with a weak, dusty top, so in warm months we start early while it's cooler.
Old slabs on raked dirt
A lot of sunken older slabs sat on dirt that was raked level instead of packed, so we dig down to firm ground first.
Cracks in the wrong places
Joints cut late or skipped let a slab crack wherever it wants, so we cut ours on time and cracks usually stay in the lines.
