What sets our Unilock work apart here isn’t just the pavers, it’s how we handle what’s underneath them: San Jose’s clay soils, seismic codes, and ADU-driven backyard builds create subgrade conditions that demand more than a standard base.

Why San Jose Residents Choose Us for Unilock Service

We’ve been laying Unilock pavers in San Jose long enough to know that a Brussels Block driveway in the 95112 ZIP behaves differently than a Copthorne patio in a newer infill lot near 95109, and we bring that same expertise to Unilock service in Communications Hill. That’s not marketing talk. It’s base prep, drainage, and edge restraint, and those details are where paver jobs either last 20 years or start shifting in three. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on remodel and commercial builds before Timberline. He’s the one who will tell you that a paver is only as good as the six inches of compacted aggregate under it. We’re not authorized by the Unilock manufacturer, and we’re clear about that. What we stand behind is our installation: the excavation, the compaction, the geotextile separation on problem soils, and the finished surface that drains right and stays put.

Our crews work with Unilock’s OEM edge restraints, base materials, and polymeric sands because those components were engineered to work with Unilock’s dimensional specs. When a job calls for sealing, we source aftermarket sealers rated for San Jose’s UV intensity and wet-dry swings rather than whatever’s on sale at the big box. You’re hiring the labor and the judgment, and that’s where we earn the call.

Common Unilock Construction Problems We Solve in San Jose

• Efflorescence on Brussels Block and Beacon Hill. San Jose’s rainy season, roughly November through March, saturates the clay-heavy subgrades under many local paver installations. When the base doesn’t drain adequately, moisture wicks up through the pavers and leaves white mineral deposits on the surface. We often see this on older driveways where the original installer skipped drainage aggregate. The fix usually involves improving base drainage and cleaning the affected course, not replacing the whole surface.
• Paver settlement and lippage from shallow base depth. Tight rear setbacks on ADU projects, especially behind 1950s ranch homes in east San Jose, often mean smaller excavators or even hand-digging. Some crews respond by skimping on base depth. We don’t. Settlement shows up as uneven paver edges and trip hazards within a couple of wet seasons. We compact in lifts and test as we go.
• Edge restraint failure where new pavers meet old concrete. Mid-century ranch properties in San Jose frequently have original concrete driveways or garage slabs that have settled and cracked over decades. When pavers abut those slabs without proper edge restraint, the paver field starts migrating outward within two or three years. We pin Unilock’s rigid edge restraints and cut a clean interface against the existing concrete so the two surfaces stay where we put them.
• Surface staining and color fade on Copthorne and Town Hall. San Jose’s dry, sunny summers deliver serious UV exposure, and unsealed pavers can bleach and pick up oil stains from vehicles, especially on driveways. We recommend sealers formulated for high-UV climates and reapply on a schedule that matches the paver’s location and traffic.
• Base failure under structurally sound pavers. We regularly see Unilock installations in San Jose where the pavers themselves are fine but the base underneath has turned to mush from poor drainage or inadequate compaction. In those cases, lifting and re-laying with proper base compaction is often a fraction of the cost of full replacement, and the pavers go right back down, tight and level.

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

San Jose’s ADU-friendly permitting environment has changed how backyards get built here. The city has actively encouraged accessory dwelling units and densification, which means homeowners across ZIPs like 95108 and 95106 are constructing detached backyard units behind ranch homes from the 1950s and 60s. Those lots were never platted for two dwellings. The result: paver patios and driveways squeezed into rear setbacks where sewer laterals, gas lines, and old irrigation pipes run directly under the proposed excavation area. We routinely hand-dig and verify lateral locations before any base work begins, because hitting a century-old clay sewer line with a machine is a five-figure mistake and a nasty phone call to the city’s building division. This is the kind of careful prep we bring to Unilock service in Alum Rock and every San Jose neighborhood we serve. This is not a standard step on a typical suburban lot in a neighboring city. In San Jose, it’s the difference between a clean paver installation and a project that turns into a plumbing emergency. When you combine that with the seismic activity near the Calaveras and Hayward faults, the subgrade under a paver surface needs to be compacted to a standard that holds up to ground movement, not just foot traffic.

Unilock Models & Products We Service in San Jose

We install and repair the full range of Unilock’s dimensional paver systems, including Brussels Block, Beacon Hill, Copthorne, and Town Hall. Each line has its own profile, color range, and thickness options, and we help San Jose homeowners match pavers to their home’s era and architecture. For repairs on existing installations, we use Unilock’s OEM edge restraints and base materials to maintain system integrity, and we stock common replacement pavers locally so we’re not waiting on a freight shipment from the Midwest to finish your driveway. For sealing and joint stabilization, we use aftermarket products chosen specifically for San Jose’s UV exposure and wet-winter cycles. Our Unilock sales & service work covers everything from new construction to selective repair, and we’ll tell you honestly when paver replacement makes more sense than patching.

FAQs – Unilock Construction in San Jose

Do San Jose’s ADU rules affect how you install a Unilock paver patio or driveway behind an existing home? Yes. San Jose allows detached ADUs on single-family lots, but those backyard units often sit close to lot lines with sewer laterals and utility lines running under the yard. Before we excavate for a paver base, we hand-dig and verify lateral locations, and we may need to adjust the paver layout to avoid loading those lines. Call (866) 253-5808 and we’ll check your specific site.

How does San Jose’s clay soil and rainy season impact Unilock paver installations? San Jose’s clay soils expand when wet and shrink when dry, and the November-to-March rainy season adds saturation at the worst time for base work. We use geotextile separation fabric over clay subgrades, compact in lifts, and build drainage into the base so water moves away from the paver layer instead of pooling under it. For a quick assessment of your soil and drainage, call (866) 253-5808.

Can you match a Unilock paver to my home’s original 1920s bungalow style near downtown San Jose? In neighborhoods like 95112, with early-1900s bungalows and Victorians, we often recommend Unilock’s Brussels Block in tumbled or muted tones to echo the aged concrete and brickwork typical of those blocks. The paver profile reads period-appropriate without looking brand new. We’ll bring samples to your site so you can see them against your home’s existing hardscape.

Do you handle permits for paver driveways and patios in San Jose? Permeable paver systems sometimes trigger different permit requirements than standard surfaces, and San Jose’s permitting process has its quirks. We’ll tell you whether your specific project needs a City of San Jose Building Division permit, and we handle the paperwork when it does. Estimating the scope is free, call (866) 253-5808.

What’s the difference between repairing and replacing a Unilock paver driveway that has settled? If the base under your pavers has failed but the pavers themselves are intact, we can lift the affected area, re-compact the base with proper aggregate, and re-lay the same pavers. That typically costs significantly less than full replacement. If the pavers are cracked, chipped, or the base has failed across the entire surface, replacement is the better call. We’ll show you both options with pricing before you decide.
