San Mateo County · California
Concrete Contractors Serving Hillsborough
Hillsborough is a town built around large lots and privacy, with no commercial zoning at all and some of the highest property values in the country. Homes sit well back from winding roads behind mature oak and redwood canopy, and the driveway is often the first substantial piece of infrastructure a visitor experiences on the property.
That scale changes what a concrete project looks like here. A driveway is frequently a multi-hundred-foot approach navigating real grade, and the work is nearly always paired with landscape design, gated entries, and drainage engineering rather than being a standalone repair.

Most Requested
Concrete Services in Hillsborough
The four we're asked for most often here. Every other service we offer is available throughout the city too.
Concrete Driveways
Vehicle-rated driveways with engineered thickness, controlled cracking, and drainage that moves water away from your garage.
Concrete Patios
Outdoor living surfaces planned around furniture, foot traffic, and how your household actually uses the yard.
Stamped Concrete
Stone, brick, slate, and plank patterns pressed into fresh concrete, colored in layers and sealed for depth.
Foundations & Slabs
Structural concrete that carries the building — slab-on-grade, tilt-up panels, cast-in-place walls, and additions.
03
Property Styles Across Hillsborough
Substantial estate homes on parcels typically well over half an acre, often much larger, spanning traditional, Mediterranean, and significant contemporary architecture. Mature oak and redwood trees are a defining feature of most properties, and outbuildings — guest houses, pool houses, detached garages — are common, each generating its own access and hardscape needs.
04
Ground Conditions and Site Considerations
Hillsborough sits on genuinely varied ground, from gently rolling estate lots in the lower town to real hillside terrain climbing toward the ridge shared with Burlingame and the county's western hills. Long driveways frequently cross meaningful elevation change, and mature tree root systems are present on nearly every property.
How Hillsborough Weather Affects the Work
Moderately fog-influenced with mature tree canopy keeping much of the town shaded and cooler than the open flats nearby. Winter rainfall on sloped, heavily wooded lots takes longer to drain than on open ground, which factors into scheduling excavation and drainage work.
Concrete Problems We See Most in Hillsborough
Every city has its own recurring issues. These are the ones that come up disproportionately here.
Long private driveways over real grade
Estate driveways here often run several hundred feet and cross genuine elevation change, requiring engineered drainage and consistent base preparation over the full length rather than a simple straight pour.
Mature oak and redwood root protection
Century-old trees on these properties represent both a major landscape asset and a real design constraint, and the town takes tree protection seriously enough that layouts routinely get adjusted to avoid root zones.
Placing concrete far from the road
When the work site sits deep on a large lot, pumping and staged delivery become standard practice rather than exceptions, and access planning is a genuine part of every estimate.
Built to Last
How We Build Concrete That Survives This Ground
Whatever the soil does in Hillsborough, the answer is the same in principle: build the layers under the slab properly and design for the movement rather than hoping it doesn't happen.
This is what a slab we build looks like in section. Skipping any one of these layers is the single most common reason concrete in this area fails early.
What happens when a layer gets skipped
- 5
Concrete slab
3,000–4,000 PSI · 4" home, 6"+ vehicles
Four inches under a delivery truck cracks, every time. Thickness has to match the heaviest thing that will ever sit on it — not the family car.
- 4
Reinforcement
#4 rebar at 18" centers, chaired
Rebar lying on the base does nothing at all. It has to sit in the slab's middle third, where it can hold a crack closed instead of watching one open.
- 3
Vapor barrier
10-mil sheeting under interior slabs
Without it, ground moisture wicks up through the concrete. That delaminates coatings, lifts flooring, and leaves a garage or shop slab that never fully dries.
- 2
Aggregate base
Crushed Class 2 rock, 4–6" in lifts
Pour straight onto soil and water has nowhere to drain. It collects under the slab, softens the ground, and the support the slab was designed around disappears.
- 1
Compacted subgrade
Graded to fall, compacted to 90–95%
Skip the compaction and the slab settles unevenly within a few wet seasons. One side drops, a crack opens across the difference, and no surface repair will hold it.

The Condition We're Usually Called To
Representative comparisons of the problems that bring people to us, and what replacement achieves. Drag the handle across each frame.
Typical 1960s tract home
Driveway replacement
A driveway poured at three and a half inches on uncompacted native soil, cracked through in three places and settling toward the garage. Replacement went in at five inches over six inches of compacted Class 2 base, with rebar chaired into the slab and the fall reversed away from the house.
- Water now runs to the street instead of the garage slab
- Thickness and reinforcement rated for two modern vehicles
- Control joints cut on a grid, so future movement is directed
Shaded rear yard
Patio rebuild
A north-facing patio that stayed damp year round, growing moss in the joints and holding water against the house wall. Rebuilt with fall built into the slab, a wider footprint, and a sealed decorative finish that sheds water instead of holding it.
- Positive fall away from the building, no standing water
- Sealed surface that resists moss and organic staining
- Footprint extended to take a full outdoor dining setting
Mature street-tree frontage
Front walkway & entry
Root heave from a protected street tree had lifted three panels into a trip hazard and opened the joints to weeds. Replaced with a root barrier, a flexible joint at the tree side, and a patterned finish that ties the entry to the house.
- Trip hazard removed and the accessible route reinstated
- Root barrier installed without harming the protected tree
- Decorative finish that lifts the whole entry approach

Commercial Concrete in Hillsborough
None. Hillsborough has no commercial zoning by design, and our work here is exclusively residential estate property, sometimes including institutional work at the town's small number of civic and school sites.

Neighborhoods We Work In
Lower Hillsborough · West Hillsborough · North Hillsborough · Hayne Estate area · El Cerrito area
The town is uniformly large-lot and low-density, but West Hillsborough's terrain climbs toward genuine hillside grade with the longest, most technically demanding driveways. Lower Hillsborough tends toward gentler ground, though every property here carries mature tree canopy that shapes the design.

We come out, look at the existing conditions, and talk through what you're trying to achieve — including whether the work you're asking about is actually the work you need.
Written estimate and design decisions
You get a written scope and price, plus a walkthrough of finish, color, and layout options with physical samples where decorative work is involved.
Permits and scheduling
Where the work needs city approval or an encroachment permit, we handle the application and build the timeline around it.
Demolition and site preparation
Old material is removed, the base is graded to the drainage design and compacted properly. This stage decides how long the finished slab lasts.
Pour, finish, and cure
Concrete is placed and finished to the specification you chose, control joints are cut on a planned grid, and the slab is cured under controlled conditions.
Walkthrough and aftercare
We walk the finished work with you and leave you with clear guidance on when you can use it and how to keep it looking right.
Aftercare
Keeping Concrete in Good Condition in Hillsborough
Four habits that do most of the work of getting three decades out of a slab in this climate.
Reseal on a schedule
Every 2–3 yearsDecorative and stamped work every two years, plain flatwork every three. Waiting until it looks tired means it has already been absorbing water for a season.
Clear and refill the control joints
AnnuallyJoints exist so the slab cracks where you chose. Packed with grit and weeds they stop working, and the slab cracks somewhere you didn't choose.
Check drainage before the wet season
Each autumnConfirm downspouts discharge past the concrete and soil hasn't built up above the slab edge. Most local concrete failures are water failures first.
Clean oil and rust quickly
As it happensPetroleum breaks down the surface paste and rust penetrates deep enough to become permanent. Degreaser and a stiff brush within a few days is enough.
