Concrete contractor in Chino Hills - slabs planned for slopes and rain
Keystone Corona Concrete is a concrete contractor based in Corona that builds driveways, patios, walks, steps, walls and slabs for Chino Hills homeowners, and I'm on site with our own crew through the pour.
Getting the base right under Chino Hills concrete
Most of our work is flatwork, the driveways, patios and walks that lie on the ground, along with slabs, walls and concrete floor installation in a garage or an addition. What I care about most is what's under it. A slab on poor prep cracks no matter how good it looks the first week.
Price moves with the size, how much old concrete comes out, how much digging and base work the ground needs, and the finish you pick. The schedule turns on any permit, the weather and curing, the wait while fresh concrete hardens enough to take weight. On a tight budget I'll trim the finish before the base, because the base keeps the slab from settling. Your written estimate spells out what's included.

How a Chino Hills job runs
Call or send a request
Call us or send the form with a few lines about the job and where it is, and we'll get back to you to set a time for me to come out.
I walk it with you
I look at the ground, the slope and the old concrete with you and tell you what I'd do and why. Then you get a written estimate showing what's included.
We schedule and pour
Once you say go, we set the schedule and handle any permit paperwork, which the city takes online. I'm on site with our crew from forming through finishing.
What rain and slopes mean for concrete in Chino Hills
The city's own code says the hills, along with how the streets and storm drains are laid out, can turn heavy rain into flooded roads and landslides that sometimes block the way in. So I check where water runs on your lot before anything gets formed, and we slope the slab to send it away from the house. If a big storm's coming, we move the pour.
If you've seen the state park close its trails after a rain because the clay soil turns slick, you know what wet clay does. Where a yard has clay under it, I plan the digging and base around that. We do the same work nearby in Yorba Linda and Chino, so call or send the form and I'll come look at yours.

Chino Hills concrete questions
Do I need a permit to replace a concrete driveway in Chino Hills?
You may, because Chino Hills requires a permit from its building official for grading or excavation of any kind, apart from a list of exemptions. A new apron, curb or sidewalk in the public right-of-way also needs an encroachment permit. I'll go over what your job needs at the estimate, and we handle the paperwork before work starts.
Does a concrete retaining wall need a permit in Chino Hills?
Yes, unless it meets every condition on the city's exemption list. A wall up to 4 feet tall, or holding back less than 3 feet of soil, is exempt only when the ground behind it slopes gently, no nearby structure loads it and every part sits more than 5 feet from a property line. The city's Building and Safety Division answers permit questions.
Does my concrete contractor need a California state license?
Yes, the California Contractors State License Board requires one when the job needs a building permit, uses employee labor or totals $1,000 or more in labor and materials. We're fully licensed and insured. Chino Hills also issues a city business license to companies based outside the city, with a listed fee of $17.83.
Will my new concrete patio crack like the old one did?
Any slab can crack, but most bad cracking traces back to a base that was raked level instead of dug out and packed, so that's where I spend the time. We also cut control joints, shallow grooves that give the slab a planned place to crack as it shrinks, and we cut them on time rather than late.
