Concrete Contractor in Wilton, CA - Driveways and Slabs Built on a Solid Base

Driveways and sidewalks are on the county's list of work exempt from a building permit, but zoning limits can still apply to work on that list. So before we dig, we check what the county wants for your lot and your job.

A retaining wall no taller than 4 feet, measured from the bottom of the footing to the top of the wall, needs no county permit unless it's holding back a surcharge, extra weight like a slope or a parked truck behind it. The county keeps a separate guideline with the details for walls, so we measure the height before we plan it.

Anything submitted for a permit since January 1, 2026 has to meet the 2025 California Building Standards Code. The county also takes plans only electronically, for projects of every size, so on a job that needs drawings, they go in online rather than over the counter.

You'll usually be walking on it well before you're driving on it, and heavy trucks and trailers wait the longest, because concrete keeps gaining strength for days while it cures. I'll tell you the waits for your slab at the estimate, so you know when the driveway is out of use.

It may get hairline cracks, because concrete shrinks as it dries, and I'd rather tell you that now than promise otherwise. We cut control joints, grooves that give those cracks a straight place to form, and we dig out and pack the base, because most big breaks start with a slab settling on loose dirt.

The base decides whether the slab stays put, and it's the part nobody sees once we pour, which is why it's the first thing people want to cut. I'd spend your money there before a fancier finish, because a good-looking slab on soft dirt still sinks and cracks.
