Unilock Construction in Los Altos Hills, CA | San Bruno Construction
We provide independent Unilock paver installation and repair across Los Altos Hills, from Brussels Block driveways to Estate Wall retaining walls on steep hillside lots. What makes our Unilock work different here is simple: we’ve rebuilt enough paver jobs in this town to know that drainage, grade, and fire code requirements in Los Altos Hills are nothing like what you’ll face in a flat Peninsula neighborhood. If you’re planning a Unilock driveway, patio, or wall, call (866) 472-1908 for a free on-site estimate. We’ll inspect your site, talk through what the hillside ordinance means for your project, and give you a straight answer on cost.
We’re San Bruno Construction, a full-scope general contractor led by Noel Carvalho. We’re an independent Unilock service provider, not manufacturer-affiliated or authorized. But we’ve installed and repaired enough Unilock systems across the Peninsula to know which products hold up on a 30 percent grade and which ones won’t. That hands-on experience, not a sales rep’s pitch, is what drives our recommendations. You can read more about our Unilock expertise on our Unilock sales & service page.
Why Los Altos Hills Residents Choose Us for Unilock Service
Most contractors can lay pavers on a flat suburban lot. Los Altos Hills is a different animal. This town runs on 1-acre minimum lots, private roads, and hillside grading rules that demand real engineering, not guesswork. When a Unilock paver driveway starts shifting after two winters, it’s almost always because someone skimped on base depth or ignored drainage. We don’t. Our crew has rebuilt failed paver systems off Elena Road, along narrow private lanes, and on slopes where water moves fast in January and not at all in July.
Noel Carvalho trained in construction technology at Skyline College in San Bruno, where he learned to read plans and understand load paths before touching a tool. That training shows up in how we approach every Unilock job in Los Altos Hills: we look at the grade, the soil, the runoff pattern, and the town’s permitting requirements before we ever order a pallet of pavers. We use Unilock’s own recommended base materials and polymeric sands because they’re engineered to work together. We source OEM-compatible components, never off-brand substitutes. And we’re local enough to know that a project on a private road in Los Altos Hills may need neighbor coordination before the first truck arrives.

Common Unilock Construction Problems We Solve in Los Altos Hills
We see the same handful of failures repeat across Los Altos Hills, usually because someone treated this town like a standard flat-lot job. Here’s what shows up most:
- Polymeric sand joint erosion from hillside runoff. Winter storms here send water down slopes fast, and it doesn’t soak in. On a grade, that flow scours out joint sand, loosens pavers, and invites weeds within a season or two. We re-lay with proper edge restraint and a drainage plan that stops water before it eats the joints.
- Paver settlement on sloped driveways. Los Altos Hills driveways are rarely flat, and many are long runs that descend from the house to a private road. If the base wasn’t compacted in lifts or the geotextile was skipped, heavy vehicles will push pavers downhill over time. We excavate to stable soil and rebuild the base properly.
- Efflorescence on north-facing slopes. The shaded side of a Los Altos Hills lot stays damp longer than the sunny side. That constant moisture pulls salts up through pavers, leaving white streaks that look like bad concrete. We treat the source, not just the surface.
- Retaining wall block cracking or bulging. Steep lots need walls, and Unilock’s Estate Wall line works well when installed with proper geogrid reinforcement and drainage behind the wall. When those two elements get skipped, walls lean or crack within a few wet seasons. We rebuild with the reinforcement the slope actually requires.
- Heavy truck damage on narrow private roads. Delivery trucks and concrete mixers on a tight Los Altos Hills lane can crack edge pavers or collapse a soft shoulder. We stage materials carefully and use smaller vehicles where the road won’t take a full semi.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
If you live on a private road in Los Altos Hills, your project has a scheduling constraint that a generic paver contractor won’t mention until it’s already a problem. Many of this town’s private roads come with road agreements that require neighbor notification and town approval for any construction that affects access. And plenty of those roads are too narrow for a standard flatbed or a full concrete truck. On a steep drive off Elena Road, we rebuilt a failing Unilock Brussels Block driveway where winter runoff had eroded the joint sand and undermined the base. We excavated to stable soil, installed a geotextile and open-graded base, re-laid the pavers with a hidden drainage channel, and finished with Unilock polymeric sand. That driveway sheds water now. But before we could do any of it, we coordinated deliveries with off-site staging and smaller shuttle trucks, because the road couldn’t take a 53-foot trailer. That added a couple of days of lead time that a flat public-street job in Mountain View or San Bruno never needs. It’s the reality of building in Los Altos Hills, and we plan for it from the first conversation.
Unilock Models & Products We Service in Los Altos Hills
We install and repair the Unilock product lines that make sense for Los Altos Hills’ terrain and fire-risk profile. Brussels Block handles long driveway runs and holds up well on slopes. Beacon Hill gives you a more formal, tumbled look for patios and walkways. Umbriano’s smooth, contemporary surface works when the house is modern and the client wants clean lines. Estate Wall is our go-to for retaining walls on steep lots, because it accepts geogrid reinforcement and drains properly when built right. For repairs, we assess each section honestly. If individual pavers can be re-laid or swapped out and the joint sand renewed, we’ll say so. If the base has failed, a targeted fix won’t hold, and we’ll tell you that too. We won’t push a full replacement when a repair is the better call. Our Unilock sales & service experience means we know the difference.

FAQs – Unilock Construction in Los Altos Hills
Do I need a permit for a Unilock paver driveway in Los Altos Hills? Yes, almost always. Los Altos Hills requires planning and building permits for most paver driveway and significant hardscape work, especially when your lot falls under the town’s Hillside and Site Development regulations. We handle the permit application and coordinate with the town’s planning and building department. Call (866) 472-1908 and we’ll tell you exactly what your specific project needs.
How does the Town of Los Altos Hills’ hillside ordinance affect my paver patio design? The hillside ordinance restricts grading, impervious surface coverage, and slope disturbance on most Los Altos Hills lots. Your paver patio may need to be designed with permeable joints, specific drainage features, or reduced square footage to comply. We review ordinance requirements before designing anything.
Can Unilock pavers be used on steep driveways without sliding? Yes, when installed correctly. Unilock pavers hold on steep grades if the base is properly compacted, edge restraints are in place, and drainage keeps water from undermining the system. The failures we repair in Los Altos Hills are almost always base failures, not paver failures. A proper installation locks the system together.
What’s the best Unilock paver for fire-resistant construction in Los Altos Hills? All Unilock concrete pavers are non-combustible and comply with fire-resistant hardscape requirements. For the best fit with Chapter 7A defensible space rules, we usually recommend Brussels Block or Umbriano in lighter colors. Darker pavers absorb more heat and can feel uncomfortable on a summer afternoon, though any paver beats asphalt or loose gravel in a high-fire-severity zone.
How do you handle paver deliveries on narrow private roads in Los Altos Hills? We stage materials off-site or at the nearest public road, then shuttle pallets in with smaller trucks. We also coordinate with neighbors and the town when your road agreement requires notification. It adds lead time, but it prevents a 40,000-pound truck from tearing up a private lane. Call (866) 472-1908 and we’ll walk you through the access plan for your street.
