Unilock Construction in Cupertino, CA | San Bernardino Contractors

We provide independent Unilock construction service across Cupertino, from paver driveway installation to patio work tied into larger home additions. The thing that separates our Unilock work here from anywhere else: we build over the teardown-and-rebuild fill that dominates Cupertino lots, so base compaction and re-grading come before paver selection, every time.

Why Cupertino Residents Choose Us for Unilock Service

We’ve laid Unilock pavers through hundreds of Bay Area rebuilds, so we know how their unit profiles and jointing systems handle Cupertino’s expansive clay and seasonal movement. That matters here more than most cities. As an independent installer we’re free to specify the right Unilock line for your grade, drainage, and design-review constraints rather than whatever a dealer is pushing. We carry Unilock’s own edge restraints, joint sand, and compatible polymeric products on our Cupertino service trucks, not generic substitutes. Ruben Castillo runs our crews, and he’s the first to say the job isn’t the paver, it’s what’s under it. Unilock sales & service through us means one contractor owns the excavation, the base, the units, and the warranty.

Common Unilock Construction Problems We Solve in Cupertino

Here’s what actually goes wrong with Unilock work on Cupertino properties, based on what we repair and re-lay every season:

• Joint sand washout at old-to-new transitions. On 1960s ranch lots being expanded, new Unilock hardscape often meets old concrete flatwork tight to a slab edge with no proper edge restraint. Winter rains push joint sand out, edges migrate, and the whole field starts walking. We re-restrain and re-sand with Unilock-compatible polymeric.
• Rutting at driveway aprons from under-compacted base. Cupertino’s clay soils hold water, and where winter rain pools against a hillside grade, a paver driveway apron laid over loose base will rut and lip. We excavate, re-compact, and often add geotextile before setting units.
• Efflorescence and staining on smooth pavers. Lighter Unilock lines like Beacon Hill Smooth and Umbriano show white haze and water staining when drainage pitches toward the house instead of away, which is common on lots re-graded during a rebuild. We correct the pitch before laying.
• Shifting at unpermitted addition seams. Cupertino rebuilds routinely uncover decades-old unpermitted concrete or paver additions mid-project. Where new Unilock meets that old work, the seam shifts and chips. We cut back to sound base and rebuild the transition properly.
• Spalled pavers from the wrong product for the traffic load. A cobblestone line like Uni-Stone handles pedestrian work fine, but put it under daily SUV traffic on a Cupertino driveway and the surface spalls. We spec Brussels Block or a large-format smooth line instead when vehicles are involved.

Unilock Service in Cupertino: What Local Conditions Mean for Your Equipment

Cupertino’s teardown-and-rebuild cycle means the pavers we install here often go down over brand-new fill and utility trenches from a rebuild rather than virgin soil. That’s the single biggest variable, and generic paver pages miss it. On a quiet Cupertino ranch-tract street, we tore out a failing 1960s concrete walk and laid a Unilock Brussels Block path and Beacon Hill Smooth driveway apron for a new two-story addition. The old slab sat over uncompacted fill from a prior unpermitted addition, so we excavated, re-based, and re-graded the slope away from the foothill-side foundation before setting units with proper edge restraint. Those pavers have stayed locked through two wet winters. The paver choice didn’t save that job. The base work did. In Cupertino, base compaction and re-grading, not the product line, determine whether a Unilock driveway or patio stays flat.

Unilock Models & Products We Service in Cupertino

We install and service the full Unilock residential range for Cupertino projects. Brussels Block is our go-to for driveways that see heavy vehicle traffic; Beacon Hill Smooth and Umbriano large-format smooth pavers belong on patios and walkways where the finish matters; Uni-Stone cobble works for paths and accents. We stock Unilock edge restraints, joint sand, and polymeric products locally so turnaround in Cupertino stays fast. When a patio or walkway is failing only because of base or drainage, we repair and re-lay the existing units. Full replacement makes sense when the pavers themselves are spalled or the layout no longer fits the new footprint.

FAQs – Unilock Construction in Cupertino

What causes the white haze on my Unilock patio after winter rains? That’s efflorescence, and in Cupertino it usually means water is moving up through the base and evaporating through the paver surface. We fix the drainage pitch first, then clean and re-seal. The haze will come back if the water path doesn’t change. Call (855) 473-5620 and we’ll walk your patio and tell you exactly where the water is going.

Is San Bernardino Contractors an authorized Unilock dealer? No, we’re an independent contractor. That’s deliberate. We aren’t tied to a distributor’s inventory, so we spec the Unilock line your Cupertino lot actually needs. We buy direct through our supplier network and install to Unilock’s published standards.

Do you use genuine Unilock parts and accessories? Yes. Edge restraints, joint sand, and compatible polymeric products are Unilock’s own. The system is engineered to work together, and cutting corners there is the fastest way to watch a paver field fail in Cupertino soil.

Which Unilock models do you install in Cupertino? Brussels Block, Beacon Hill Smooth, Uni-Stone, Umbriano, and Senzo. We also service existing Unilock installations from any of those lines, including Unilock repair in Los Altos and throughout the area.

How long does a Unilock paver driveway take in Cupertino? A standard driveway runs three to five working days, including excavation, base compaction, setting, and joint sand. Larger jobs tied to a home addition run longer. Call (855) 473-5620 for a timeline specific to your property.
