Unilock Construction Service Nationwide

Why San Bruno Homeowners Choose Unilock Construction

We provide independent San Bruno Unilock service – paver driveway and patio installation, retaining walls, and repair work on existing Unilock surfaces. Our crew has set Unilock pavers and walls across the Peninsula for years, and we know how these systems behave in San Bruno’s fog-belt climate where damp air, clay-heavy soils, and sloped lots create specific failure modes you won’t see in drier parts of the Bay. We are not an authorized Unilock dealer – we’re a contractor who buys, cuts, and installs Unilock by name because the product holds up when the base and drainage are done right. Call (866) 472-1908 to talk through your project, whether it’s a new Brussels Block driveway or a Beacon Hill wall that’s starting to lean.

San Bruno’s marine-influenced climate keeps paver surfaces damp for months at a stretch, and that moisture works its way into joints, bases, and wall cores. What looks like a cosmetic issue – white haze on pavers, a sunken corner near the curb – usually traces back to water and base prep, not the paver itself. We handle the full scope: paver driveway installation, paver patio installation, driveway replacement, and wall repair, including Unilock service in Millbrae and surrounding areas. If you already own Unilock surfaces that are shifting, hazing, or losing joint sand, we can diagnose the actual cause and fix it without selling you a full rebuild you don’t need.

Why Trust San Bruno Construction for Your Unilock Construction?

Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College right here in town. That hands-on program taught him to read plans, understand load paths, and think through a project before a single tool comes out of the truck. Over the past two-plus decades he’s run residential projects across San Mateo County – pulling permits at City Hall on San Mateo Avenue, coordinating work in tight side yards, and rebuilding paver surfaces that were laid wrong the first time. His daughter was born in San Bruno, and that’s reason enough to care whether a driveway still locks in twenty years from now.

For Unilock work specifically, our advantage is repetition. We’ve cut and set Brussels Block, Beacon Hill, and Umbriano pavers on enough San Bruno driveways to know how each line behaves under local conditions. Brussels Block’s tumbled edges hide minor lippage well but its textured surface holds fog moisture longer than smooth pavers, which is why we’re specific about joint sand selection and slope. Beacon Hill wall block is rugged, but on a San Bruno hillside lot the wall is only as good as the geogrid and drainage behind it. We spec base depth, geogrid, and drainage for the actual soil and slope, not a generic spec sheet. Good construction doesn’t announce itself – it just works, year after year.

We’re a full-scope general contractor, not a paver-only crew, so when your Unilock project touches a foundation retrofit, a new retaining wall, or drainage that ties into existing hardscaping, we coordinate the whole scope under one contract. No finger-pointing between the paver crew and the drainage crew because there isn’t one.

Common Unilock Construction Problems We Fix in San Bruno

Here’s what we see repeatedly on Unilock installations around San Bruno, and what’s actually causing each issue:

• Efflorescence on Brussels Block and tumbled pavers. That chalky white bloom across the surface is water-soluble salts migrating through the paver. San Bruno’s persistent fog plus irrigation overspray keeps pavers damp, so the salts keep rising. The haze often shows up worst on north-facing and shaded sections. The fix is usually moisture management and a proper joint system – not sealing over the problem, which can make it worse.
• Polymeric sand washout on sloped driveways. Winter storms push water down San Bruno driveways fast, and if the slope exceeds what the joint sand can hold, the sand erodes. Pavers shift, ruts form, and the driveway starts moving. We re-slope the surface where possible, use a high-performance polymeric sand rated for the grade, and install sturdy edge restraints so the entire field stays locked in.
• Base failure and settlement on clay-heavy soil. San Bruno’s flatlands and lower hills hold a lot of clay. A paver driveway set over two or three inches of uncompacted gravel will rut and settle within a couple of wet winters. We’ve pulled back pavers off El Camino and found exactly that – a thin, soft base over clay. The fix is removing the bad base, compacting six inches of Class II aggregate in lifts, and only then setting the pavers.
• Beacon Hill wall block separation and leaning. Retaining walls on sloped San Bruno parcels fail when geogrid reinforcement or back-drainage was skipped. Block separations and bulges don’t fix themselves – the block line keeps creeping downhill each wet season. We rebuild the wall with proper grid placement, clean drain rock, and a drainage path that actually exits daylight, not into the wall’s core.
• Edge restraint failure along curbs and borders. Driveways and patios in San Bruno’s tight lot lines often butt against concrete curbs, house slabs, or fences. When the edge restraint isn’t anchored well, the outer rows of pavers creep outward and gaps open up. We re-anchor the restraint with appropriate spikes or concrete, then re-set the edge pavers so the field stays square.

Unilock Parts & Our Repair-vs-Replace Approach

We source genuine Unilock pavers and wall units for color and dimensional matches on Unilock repair in Pacifica and throughout the Peninsula. Unilock’s color blends vary by manufacturing batch, so when we patch a section of a Brussels Block driveway, we match the existing field as closely as the current batch allows and orient the new pavers to minimize visible difference. For joint sand and edge restraints, we use quality aftermarket products where Unilock doesn’t specify one – the critical part is choosing a polymeric sand rated for San Bruno’s moisture and grade, not buying a bag with the brand name on it.

Our repair vs replace decision is straightforward. If a driveway or patio has isolated settlement from a soft spot or an old utility trench, we re-level that section, re-compact, and re-sand the joints. If the base is failed across the field – which we check with test pits, not guesswork – replacement is the honest call. Patching a fifty-square-foot band of failed base while the rest keeps settling just spends your money twice. Call (866) 472-1908 and we’ll tell you which situation you’re in.

Our Unilock Service Process – Step by Step

Here’s how a typical Unilock project runs with us, from first call to final walkthrough:

1. 1
   Diagnosis and base check. We assess the existing surface – or the raw site for new work – and dig test pits to see what the base actually is. On an existing Unilock driveway, this tells us whether we’re repairing a section or rebuilding the field. We check slope, drainage, and edge restraint condition before quoting anything.
2. 2
   Repair or installation plan. For repairs, we specify which pavers or wall units we’ll source, what base work is needed, and the joint sand spec. For new installations, we spec base depth for San Bruno’s soil, set the slope for drainage, and plan the edge restraints and any geogrid for walls.
3. 3
   The work itself. We remove and salvage reusable pavers where possible, excavate to the proper depth, compact the subgrade and Class II base in lifts, set the pavers or wall block per Unilock’s installation specs, and install edge restraints. For walls, geogrid goes in at the right layers with clean drain rock behind.
4. 4
   Joint sand and finishing. We sweep in polymeric sand, compact the surface, and activate the sand with a controlled water application. This is the step that makes or breaks a paver job in San Bruno’s climate – too little water and the sand doesn’t set, too much and it washes before it cures.
5. 5
   Test and walkthrough. We check drainage by observation, verify the pavers are locked under traffic, and walk the site with you. Any adjustments get made before we call the job done.

Unilock Products We Service & Install in San Bruno

We install and repair Unilock in South San Francisco and San Bruno, working with the full range of products commonly used on local properties. Brussels Block is the workhorse for driveways and patios – a tumbled, dimensional paver that takes traffic well and has a classic look. Beacon Hill gives us an estate-style wall and paver option with bigger scale for larger properties. Umbriano’s large-format slab profiles suit modern home fronts and wider patios. For retaining walls, we work with Unilock’s tumbled wall block systems, including Seneca Ridge profiles, spec’d with proper geogrid on sloped San Bruno lots. We also service paver driveways, patios, and walls installed by others – most of our repair calls are on surfaces we didn’t originally build.

We Also Service These Brands

We’re not tied to one manufacturer. Beyond Unilock, we work with KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, and Kohler, Moen, Grohe, Delta, and Toto plumbing fixtures. That’s the point of a full-scope contractor – your paver patio can be part of a larger remodel without juggling separate vendors.

FAQs – Unilock Construction Service in San Bruno

Do you install genuine Unilock pavers, or do you substitute another brand?
We install genuine Unilock pavers and wall units. We buy them by name and cut them to fit the site. If you want a different brand – Belgard or Tremron, for example – we can quote that too, but when the job calls for Unilock, that’s what gets installed. Call (866) 472-1908 for a project-specific quote.

Why does my Unilock paver driveway keep turning white?
That’s efflorescence – water-soluble salts rising through the paver and crystallizing on the surface. In San Bruno’s fog-belt climate, the pavers stay damp for long stretches, and irrigation overspray adds more moisture. It’s not a manufacturing defect and it doesn’t harm the paver structurally. We address it by fixing moisture sources and using a proper joint system; a full explanation comes with the estimate. Call (866) 472-1908 to have us look at your driveway.

Can you fix a sunken section of pavers without redoing the whole driveway?
Yes, if the settlement is isolated. A sunken band over an old utility trench or a soft spot at the curb can often be re-leveled by pulling that section, rebuilding the base, and re-setting the same pavers. If the base is failed across most of the field, a full replacement is cheaper in the long run. We test the base before quoting so you know which call applies. Reach us at (866) 472-1908.

How deep does the base need to be for Unilock pavers on San Bruno soil?
For driveways on San Bruno’s clay-heavy soils, we specify six inches of compacted Class II aggregate over a prepared subgrade. Four inches is the bare minimum for pedestrian patios on good soil, but driveways take more. Skimping on base depth is the number one reason we get called to rebuild paver driveways that are five years old and already rutted. Call (866) 472-1908 to discuss your site conditions.

Can Unilock wall block hold a retaining wall on a sloped San Bruno lot?
Yes, when the wall is engineered properly. Unilock wall block itself is strong – the fail point is usually missing geogrid, skipped drainage, or a poorly compacted base. On San Bruno hillside lots, we add geogrid layers and clean drain rock behind the wall to hold the slope. If your wall is leaning or separating, call (866) 472-1908 before it gets worse.

Is San Bruno Construction authorized by Unilock?
No, we’re an independent contractor, not an authorized Unilock dealer. That means we can’t extend or modify Unilock’s manufacturer warranty, but it also means we’re free to spec the right base, drainage, and edge restraint for San Bruno conditions rather than a one-size-fits-all installation. We install the product correctly, and we stand behind the workmanship.
