Concrete Contractors Serving San Bruno
San Bruno sits in the shadow of San Bruno Mountain, close enough to San Francisco International Airport that flight paths are part of daily life in parts of the city, and close enough to the coastal gap that fog is a near-constant presence. It's also grown into a genuine tech employment hub with YouTube's headquarters anchoring the Bayhill Office Park.
Residentially, the city is a mix of hillside neighborhoods that climb toward the mountain and flatter valley streets closer to El Camino Real, and the concrete work splits along those same lines — slope and drainage on one side, straightforward tract renewal on the other.

Most Requested
Concrete Services in San Bruno
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.

Property Styles Across San Bruno
The valley floor near downtown and El Camino holds modest postwar homes on regular lots, largely from the 1950s. Neighborhoods climbing toward San Bruno Mountain and the western hills have later development with more slope, larger lots in places, and driveways engineered for grade rather than a flat approach.
04
Ground Conditions and Site Considerations
San Bruno Mountain dominates the western skyline and shapes the terrain across much of the city, with hillside neighborhoods bringing real grade, retaining considerations, and engineered drainage into the picture. The valley floor near downtown and the Caltrain corridor is comparatively flat and straightforward.
How San Bruno Weather Affects the Work
San Bruno sits in the coastal fog belt, with cool, often overcast conditions common through much of the year, moderated somewhat compared to Pacifica or Daly City but still requiring the same patience with curing that fog-belt cities need. We schedule around the marine layer rather than assuming warm, dry conditions.
Concrete Problems We See Most in San Bruno
Every city has its own recurring issues. These are the ones that come up disproportionately here.
Hillside drainage toward San Bruno Mountain
Properties climbing the mountain's lower slopes need runoff directed deliberately, since undirected water on this terrain finds its own path and it's rarely a convenient one.
Aging postwar driveways in the valley
The flatter neighborhoods near downtown have original 1950s driveways reaching the end of a long service life, typically cracking first at the garage approach.
Cool, damp curing conditions
Fog-belt moisture slows strength gain in freshly placed concrete, which we account for with extended curing schedules rather than working off a warm-climate timeline.
Built to Last
How We Build Concrete That Survives This Ground
Whatever the soil does in San Bruno, 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.
Transformations
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
Drag the handle — or use the arrow keys — to compare the condition before and after.

What Working With Us Looks Like
From first call to finished slab, here's how a San Bruno project runs.
Free on-site consultation
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 San Bruno
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.
