Our team installs and repairs Unilock Unilock sales & service across the Peninsula, and we’ve learned that what fails in San Bruno is rarely the paver itself. It’s the base, the drainage, or the edge restraint underneath. We’ll get into that below.

Why San Bruno Residents Choose Us for Unilock Service

Noel Trevino, our owner and general contractor, grew up around construction in Southern California and has spent nearly three decades fixing the kind of work that looks fine for two years and then gives out. That experience shapes how we approach Unilock jobs in San Bruno. We don’t install a paver field and walk away. We check what’s underneath it first.

San Bruno homeowners call us because we know the difference between a paver that failed and a base that was never built right in the first place. We carry genuine Unilock Brussels Block, Beacon Hill Flagstone, and Copthorne units for repairs, and we keep quality aftermarket base aggregate, geotextile fabric, and polymeric joint sand on hand for the rebuild work that most paver fixes actually need. We serve the entire San Bruno service area, and we schedule around your timeline, not ours.

Common Unilock Construction Problems We Solve in San Bruno

• Efflorescence and salt-air staining on Brussels Block and Beacon Hill slab pavers. San Bruno’s marine fog keeps paver surfaces damp for hours after the sun burns off in Millbrae or South San Francisco. That lingering moisture pulls mineral salts to the surface and invites seasonal algae growth. The fix is usually a joint sand replacement and a drainage correction, not a chemical wash that comes back next winter.
• Base failure and rutting on sloped driveways. San Bruno’s small hillside lots shed water fast. A driveway laid over thin class-II aggregate with no geotextile separator will show lippage and ruts within a couple of wet seasons. We see it constantly on mid-century homes where the driveway was poured decades ago and later capped with pavers by a crew that skipped the base work.
• Joint sand washout and edge restraint creep at garage aprons. Where a paver driveway meets the concrete garage apron, vehicle push against the field is relentless. Without a proper edge restraint, the outer course of pavers drifts, joints open up, and the field starts to look like it’s being pulled apart. We rebuild these with a deeper compacted base and a rigid edge restraint, then re-sand with polymeric joint sand that sets firm.
• Retaining wall block bulging on terraced hillside lots. U-Cara and Copthorne walls are only as good as the geogrid and drainage gravel behind them. On San Bruno’s terraced lots near fault-zone setbacks, we’ve seen walls lean out within five years because the original installer treated a structural wall like a garden border. If the wall has moved, we rebuild it with proper reinforcement and a drainage pipe at the heel.
• Paver discoloration from standing water at planter edges. Low spots along paver patios that sit next to planter beds in San Bruno’s small backyards collect organic runoff and fog moisture. The pavers stay damp, the joint sand washes into the planter, and a dark stain creeps across the field. We regrade the sub-base, reset the pavers, and add clean drainage before re-sanding.

Unilock Service in San Bruno: What Local Conditions Mean for Your Equipment

Here’s what most paver pages won’t tell you about San Bruno. This city sits directly over the San Andreas Fault zone, and the 2010 PG&E gas pipeline explosion in Crestmoor changed how our building department reviews nearly every hardscape plan. A paver patio or driveway near the El Camino corridor or the BART/Caltrans right-of-way gets looked at through the lens of seismic stability and underground utility clearance. Neighboring cities like Millbrae or South San Francisco simply don’t have that same permitting history.

That means your Unilock driveway replacement in San Bruno may need an engineered base detail and a drainage plan on the permit set before we can pull the permit. We handle that paperwork as part of the job. We’ve done enough of these to know which plans get through the first review and which ones come back marked up. If the details aren’t right on paper, they won’t be right in the wall, or in this case, in the base under your pavers.

Unilock Models & Products We Service in San Bruno

We routinely install and repair four Unilock product lines that show up most often in San Bruno homes: Brussels Block, the tumbled concrete paver that dominates mid-century driveway replacements; Beacon Hill Flagstone, a smooth slab paver used for patios and walkways; Copthorne, the clay-look wall block; and the U-Cara Wall System for segmental retaining walls on hillside lots.

For repairs, we use genuine Unilock units so the color, texture, and dimensional tolerances match the existing field. For the base, drainage, and edge restraint work that actually determines how long the job lasts, we spec quality aftermarket materials because that’s where the original installation usually went wrong. When more than about a third of a paver field has settled or a wall has moved, we recommend a full rebuild. Patching a failed base just moves the problem six feet over.

FAQs – Unilock Construction in San Bruno

Can you match my existing Unilock pavers if only part of the driveway failed? Yes, we source genuine Unilock units in the same color and profile as your original field, and we blend the replacement area so the repair doesn’t look like a patch. Fair warning: if the base under the failed section is thin or un-compacted, matching the pavers is the easy part. Fixing what’s underneath is what actually costs money. Call (877) 752-3154 and we’ll tell you straight which situation you have.

Does San Bruno’s fog and salt air really damage pavers, or is that a sales pitch? The fog is real, and it matters. San Bruno’s marine layer keeps paver surfaces damp longer than inland Peninsula cities, and that lingering moisture accelerates efflorescence, algae growth, and joint sand breakdown. The pavers themselves are concrete and they’ll hold up. The failure usually shows up in the joints and the base. If your pavers look chalky or green every spring, the drainage and joint sand need attention, not the pavers.

Do I need a permit for a paver patio or driveway in San Bruno? In most cases, yes. Because San Bruno sits in the San Andreas Fault zone and carries post-2010 utility-scrutiny requirements from the Crestmoor pipeline incident, hardscape work near the El Camino corridor and BART right-of-way often requires an engineered base and drainage detail on the permit set. We pull permits and schedule inspections as part of the job. Call (877) 752-3154 and we’ll check your specific address against current city requirements before you spend a dollar.

How do you build a paver retaining wall on a San Bruno hillside lot? We build them as structural walls, not garden borders. That means a compacted aggregate base, geogrid reinforcement at the design spacing, drainage gravel and a perforated pipe at the heel, and genuine Unilock U-Cara or Copthorne blocks. San Bruno’s terraced lots and fault-zone setbacks leave no room for a wall that leans out after three winters. If an existing wall has moved, we don’t shim it. We take it down and rebuild it right.

Is it cheaper to replace my failed paver driveway in concrete? Sometimes, but not always. A concrete driveway runs $4,500 to $12,000 in San Bruno, which is less than a full paver rebuild. But concrete doesn’t give you the same permeability or the same look as Unilock pavers, and it cracks differently in our clay-heavy soil when the ground moves. We’ll price both options for you at the estimate. Call (877) 752-3154 and we’ll lay out the numbers side by side.
