Concrete Contractor in Atherton, CA - Slabs Laid Level Among the Oaks
Hallmark Menlo Park Concrete is a concrete contractor pouring driveways, patios, steps, walls and foundations in Atherton, CA. We put most of our care into the ground under the slab, the part you won't see once it's poured.
Concrete work under Atherton's trees
Atherton runs as its own town, with its own building, planning and public works offices. The town describes its six square miles as covered in native live oaks, white oaks, bays, redwoods, cedars and pines. On a driveway or patio job that matters, because roots can run closer to a slab than you'd guess from looking at the trunk.
We pour driveways, patios, walkways, steps, retaining walls and foundations here, the same work we do in Menlo Park and Redwood City. Most of what decides how a slab holds up happens before the pour, in the base, the forms and the drainage, so that's where I spend the time on an Atherton job.
What we check on the ground first
Before I price a job, I look at what's growing near it and whose it is. Outside the few places the town looks after, such as the medians and the Town Center, trees in Atherton are the property owner's or the neighbor's responsibility, so a root under your driveway is usually yours or the next lot's to deal with. Then I check the soil and where the water runs.
- Roots under the slab. Where a tree grows close, its roots can lift and crack a slab over time, so we find where they run before we set the forms.
- A raked base. If the subgrade, the dirt a slab sits on, was only raked level and not dug out and packed, the slab settles as that dirt does.
- Water toward the house. A slab that tips back toward the house sends water against the foundation, so we check the fall of the forms before we pour, not after.
Driveways, patios and foundations for Atherton homes
A lot of concrete work starts with something you can see: a driveway cracked across, a patio sunk at one corner, or water pooling by the garage door. Where that's happening, the old base is usually the reason, so we break out the slab, dig down to firm ground, pack a new base and cut control joints, planned grooves that give the slab a straight place to crack.
Other jobs start before there's anything to look at, with an addition, a garage or a cottage that needs a slab foundation or footings under it. There the forms and the measurements matter most, because a foundation that's out of level shows up in every wall built on it.

Common questions about concrete in Atherton
Do I need a permit to replace a concrete driveway in Atherton?
The town's Building Department decides that, since it issues permits for building and altering structures in Atherton, and we check with it for your address before we set a date. When your job needs a permit, we handle the paperwork or help you with it, and we don't start until it's in place.
Does a concrete contractor in Atherton need a California license?
Yes, under the state licensing board's rules, when the job needs a building permit, uses extra workers, or labor and materials add up to $1,000 or more. A bigger job can't be split into smaller contracts to stay under that line. The town issues its own business license to contractors too, and we're licensed and fully insured.
Can you pour a driveway near a heritage oak in Atherton?
Only once the town has issued a permit, if the work would remove, disturb or damage a heritage tree or do something prohibited inside its tree protection zone, the defined area around it. I look at the trees near the work at the estimate, and we sort out that permit before we dig.
How much does a new concrete driveway cost in Atherton?
The price comes from the size, the old concrete coming out, how deep we dig for a firm base and the finish you pick, so I give you a number once I've measured on site. If money's tight, I'd choose a plain broom finish, a light texture for grip, before I'd cut the base.
Will my new concrete driveway crack like the old one did?
It may crack a little, because most concrete does, but a packed base and control joints, the grooves we cut so it cracks along a straight line, usually keep that small and out of sight. I'll also tell you up front how long to stay off it while it cures, the slow hardening that makes it strong.
