Why a new slab in Chino is worth doing right

Most people call us when they can see the problem. A driveway cracked across, a patio sunk toward the house, water pooling where it shouldn't, a walk with a lip that catches a toe. Usually the old slab wasn't the real problem. What it sat on was.

So I plan the part you won't see. We dig out to firm ground, pack the subgrade, the soil and gravel the slab sits on, and set the grade so water runs away from your house. Where a slab carries a car we usually add rebar, steel that holds cracked pieces together, and we cut control joints, shallow grooves that give the concrete a place to crack where we chose.

If the budget's tight, the base is the last place I'd cut, because a nice finish on poor prep still cracks. The same goes for concrete steps up to a front door, where one settled corner tips every tread.

Heat and timing shape a pour in Chino

Chino's summers are the first thing I plan around. NOAA's long-term averages give the city about 99 days a year at 90°F or hotter, 23 of them at 100°F or more. Concrete finished in midday heat dries too fast on top and turns weak and dusty later, so in summer we pour early and keep the slab damp while it cures, the slow hardening that sets its strength.

Price moves with the size, how much old concrete comes out, how much base work the ground needs and the finish you pick, since a broom finish, the light texture that gives shoes and tires grip, costs less than stamped work. The schedule turns on any permit, the inspections and the cure. Your written estimate spells out the rest.

Rain matters too, even with only about 10 inches a year, because a slab that falls toward the house can go unnoticed until the first real storm. I check where the water runs before we set a form, the same way we do in Chino Hills, Eastvale and Temescal Valley. Ask for an estimate and I'll walk your yard with you.

Chino concrete questions, answered

Do I need a permit for a new concrete driveway in Chino?

It can, so check before anyone pours. Chino's Building Division issues permits for all work except what the state codes exempt, and its examples of exempt work are painting, carpet, tile and small repairs, not concrete. If your job needs one, I'll go over it at the estimate and we'll handle the paperwork.

How long does a building permit last in Chino?

The city's building FAQ, written before the current code, says a permit expires 180 days after it's issued or 180 days after work stops. The building official can grant one free 180-day extension if a letter with the reason arrives before it expires. On most flatwork we start soon enough that it doesn't come up.

Does an out-of-town concrete contractor need a Chino business license?

Yes. Chino requires a city business license from anyone doing business in the city, and that includes contractors from out of town. It's a fair question to ask any contractor you're considering, along with their state license.

When does a concrete contractor need a California state license?

The Contractors State License Board says anyone who builds or alters a structure in California needs its license when the job needs a building permit, uses extra workers, or costs $1,000 or more in labor and materials. We're fully licensed and insured, and you should ask any contractor before you sign.

Will my new concrete patio crack like the old one did?

Concrete can still crack, but good prep keeps cracks small and inside the joints we cut for them. Most bad cracks start with a base that settled or water running under the slab, so we dig out and pack the base, slope it away from the house and cut joints on time.

How long until I can drive on a new concrete driveway?

Expect to walk on it after a few days and wait longer before you drive on it, because concrete keeps gaining strength while it cures. I'll tell you the wait for your slab at the estimate so you can plan where the cars go.
