Unilock Construction in Los Altos, CA

Unilock Construction in Los Altos, CA | San Bruno Construction

We’re an independent construction and hardscape crew that installs and repairs Unilock pavers and segmental walls across Los Altos. We are not authorized by, affiliated with, or sponsored by Unilock, and we won’t claim to be. What we are is a general contractor who has torn out and rebuilt enough failed paver systems on Los Altos lots to know exactly where the problems start. The short version: most Unilock failures we see in Los Altos come down to the base and the edge, and that’s where we focus first. Call (866) 472-1908 to ask about your driveway, patio, or wall.

We carry Unilock sales & service depth that comes from years of working with Brussels Block, Cambridge, Beacon Hill, and the Estate Wall line as part of full remodels. Serving Los Altos service area zip codes 94022, 94023, and 94024, we understand that nearly every project here is a remodel, addition, or scrape-and-rebuild, not a fresh tract lot. That shapes what gets built, where it fits, and what the city will sign off on. If your hardscape sits inside that equation, we handle the coordination.

Why Los Altos Residents Choose Us for Unilock Service

We know Unilock service in Los Altos Hills and the surrounding area, and we know Los Altos. Those two things matter more than any manufacturer badge. A paver driveway or retaining wall on a flat, open lot can forgive a mediocre base. On a Los Altos lot with a tight setback, a saturated hillside-adjacent slope, or a coverage envelope that the city already scrutinized, it will not. The failures we see each winter follow the same script: a base that wasn’t free-draining, an edge restraint that wasn’t set tight to grade, and joints that pumped out by February.

Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where the program taught him to read plans and understand load paths before a tool comes out of the truck. He’s run residential jobs across San Mateo County for more than two decades, and he brings that same read-the-plans-first discipline to Unilock service in Stanford and every Unilock patio, driveway, and wall we handle in Los Altos.

Because we’re our General Contractor in Los Altos, not a paver-only subcontractor, the paver work fits into the larger project. The driveway ties into the hardscaping. The patio interfaces with drainage. The wall respects the grading. One crew coordinates the whole thing, so the paver edge doesn’t end up fighting the downspout or the property line.

Common Unilock Construction Problems We Solve in Los Altos

Here’s the list of what we see most often, and what it actually means for the owner:

• Polymeric sand joints washing out after an atmospheric-river winter. Los Altos gets its rain in concentrated bursts. When water saturates a base that wasn’t open-graded and free-draining, the joints pump and erode. We see this every spring on driveways across 94022 and 94024. The cure isn’t sweeping in more sand; it’s fixing the base.
• Efflorescence and salt bloom on Brussels Block and Cambridge paver faces. White haze after a wet winter isn’t a defect. It’s moisture migrating through the paver and carrying minerals to the face. It often means the base is holding water. Los Altos hillside-adjacent lots make this worse because the soil sits wetter longer.
• Soldier-course and edge-restraint creep on sloped driveways. On a narrow Los Altos lot, the driveway slope fights the edge every time a car turns on it. If the restraint wasn’t set against a concrete toe or properly staked edge, the outer course walks outward toward the setback line. It’s slow, but it’s steady.
• Segmental retaining wall movement after saturated ground conditions. Walls built without proper drainage behind them lean and bulge when winter storms saturate the hillside-adjacent soil. We rebuild more walls in Los Altos for this reason than for any other single failure.
• Paver systems installed without enough thought to lot coverage and grading. A patio or driveway that looked fine on the original plan sometimes ends up redrawn after the city reviews the coverage math. We’ve had to recut hardscape scope on more than one Los Altos project to keep the project moving.

Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment

Here’s the Los Altos-specific detail that most contractors miss. Los Altos enforces lot-coverage and floor-area-ratio limits strictly, and nearly every project here is our Home Remodeling in Los Altos — an addition, or scrape-and-rebuild rather than a new tract lot. What that means for hardscape: a paver driveway or patio often has to fit inside coverage and setback math the city already reviewed during plan check. So the hardscape scope frequently gets redrawn after design review, not before. We’ve had projects where the paver driveway passed plan check, then the city flagged the rear patio mid-remodel because it pushed total impermeable coverage over the line. So we recut the patio, rebuilt the edge tight to the new line, and kept the project moving. That’s not a conversation most paver installers have had, but in Los Altos it’s a normal Tuesday.

On a scrape-and-rebuild off a downtown cottage lot near the village core, we tore out a failed paver driveway whose polymeric joints had pumped through two winters and whose soldier course was creeping into the setback line. We re-excavated to a free-draining open-graded base, reset edge restraint tight to grade, and reinstalled Unilock Brussels Block with ArmorTec. The crew then cut and relaid the rear patio to stay inside the lot-coverage envelope the project had cleared at plan check. The driveway has now taken two atmospheric-river seasons without joint wash or edge movement.

Unilock Models & Products We Service in Los Altos

Most of what we install or repair in Los Altos falls into four Unilock lines: Brussels Block, Cambridge Pavingstones with ArmorTec, Beacon Hill Flagstone, and the Estate Wall or Brussels Dimensional Wall system. Each one has specific characteristics that matter here. Brussels Block is forgiving and classic, but it shows efflorescence quickly on a wet base. Cambridge with ArmorTec gives a harder face but its interlocks punish a sloppy edge. Beacon Hill reads well for paths and patio accents on California-modern remodels, but it’s less tolerant of a subgrade that shifts. On retaining walls, Estate Wall is the workhorse, but its drainage design is non-negotiable on a hillside-adjacent Los Altos lot.

We stick with Unilock’s own system components: the pavers, the matching edge restraints, the specified base and joint materials. Mixing aftermarket parts into a segmental system is precisely what causes joint and edge failures down the road. If the base and restraint are sound, we repair. If the base has failed or the wall has moved, we rebuild rather than patch and pretend.
