Campbell’s housing stock tells a specific story. Nearly every neighborhood here was carved from prune and apricot orchards between 1955 and 1975, leaving a city of small ranch homes on modest lots with original concrete driveways, shallow slabs, and soil high in expansive Santa Clara Valley adobe clay. That clay swells when winter rains hit, then shrinks through dry summers, and it does not forgive a paver base that was skimped on or an edge restraint that was under-spec’d. We’ve seen Unilock systems fail in Campbell for reasons that would not apply in flatter, sandier parts of San Jose, and we’ve learned to build for this ground.

We are not affiliated with or authorized by Unilock. We are an independent paver and hardscape crew that has worked with Unilock products across the South Bay for years, including Unilock service in Saratoga. Our expertise comes from field experience with Unilock’s regional product line and California base-and-drainage requirements, not from any manufacturer warranty relationship.

Why Trust Rowan Construction Group Campbell for Your Unilock Construction?

Grant Rowan grew up in Beverly Hills and picked up his first framing hammer before he could drive, shadowing a neighbor who remodeled kitchens on weekends. He trained at Santa Monica College’s Construction Technology program, where he learned to read blueprints, calculate load paths, and pull a permit correctly the first time, before moving into Kitchen Remodeling and broader construction work. Over the course of his career he has run residential and commercial projects across the South Bay and Silicon Valley foothills, including several gut-renovations near the Pruneyard Shopping Center area in Campbell that required careful coordination with city inspectors and active neighboring businesses. That background matters when your Unilock driveway replacement needs a structural evaluation because your 1962 cripple-wall home triggers seismic review under current Campbell building department rules.

Our crews are background-checked and uniformed. A live person answers our phones 24/7. Every visit produces a documented photo record, included as standard, not sold as an upgrade. Under Clause 1 of the Haven Standard, the price is written before anyone picks up a tool, and no change proceeds without a signed change order. That discipline is why our projects finish within a few percent of the agreed number. Measure twice, document once, build it right.

On Unilock specifically, we stock Unilock-compatible edge restraints, polymeric sand, and base aggregates locally. We know which Unilock colors and textures are currently available through regional distribution, and we know the base prep that keeps them flat on Campbell’s adobe clay. We do not guess at compatibility, and we do not promise what we cannot source.

Common Unilock Construction Problems We Fix in Campbell

• Efflorescence on Brussels Block and Copthorne pavers. The white, powdery bloom that shows up after winter rains or irrigation overspray is calcium hydroxide migrating to the surface. In Campbell, it is worse on north-facing driveways and patios where moisture lingers longer, and it is worse still if the original installer used a base aggregate with high soluble-salt content. We strip the efflorescence with a cleaner matched to the paver type, then assess whether the base drainage needs correction so the problem does not recur.
• Polymeric sand loss and joint erosion. Campbell’s clay soils swell and shrink seasonally, flexing the paver bed and cracking polymeric sand joints. Once the sand is gone, weeds move in and pavers start to shift. We remove the remaining loose material, re-sweep with fresh polymeric sand formulated for Bay Area temperature swings, and mist-activate it properly so it sets to the correct depth.
• Edge restraint failure and toe-out on driveway aprons. Where Unilock pavers meet existing concrete or asphalt, the edge restraint takes the load of vehicle traffic turning in and out. In Campbell, many original driveways are narrow 1950s concrete aprons with no proper expansion joint, and the steel or plastic restraint rusts or cracks under seasonal ground movement. We replace with heavy-duty aluminum or concrete curb restraint, pinned and backfilled for the load.
• Faded or chalky surface on Umbriano pavers. Umbriano’s exposed-aggregate finish is durable but not immune to years of UV and pool-chemical splash. In Campbell, where summer sun is intense and many homes added pools in the 1970s and 1980s, we see this most on south-facing pool decks. The surface is not structurally failed, but the aesthetic is gone. We assess whether a color-enhancing sealer restores the depth or whether replacement of the affected field is the honest call.
• Base failure from inadequate drainage on former orchard soil. Campbell’s adobe clay holds water. If the original Unilock installer skipped the geotextile fabric or used too little permeable base aggregate, winter rains saturate the subgrade and the pavers heave. Our crew re-laid a sinking Unilock Brussels Block driveway in a Campbell neighborhood where the edge restraint had rusted out and rain runoff was undermining the base. We pulled the pavers, re-compacted and re-graded the aggregate base, reset a new edge restraint, and reinstalled the Brussels Block with polymeric sand, and the driveway has stayed flat and tight through two wet seasons.

Unilock Parts & Our Repair-vs-Replace Approach

We use Unilock-compatible OEM-style edge restraints, polymeric sand, and base aggregates. For sealers and cleaners, we use quality aftermarket products where the chemistry is equal or better, and we tell you which is which before application. We do not mark up parts and pretend they are something they are not.

If a section is heaved but the pavers are sound, we lift, re-grade, and re-set. This is common in Campbell where a downspout was dumping onto one corner of a patio or where a tree root has lifted a small field. If a large area has failed restraint, widespread efflorescence from bad base chemistry, or base saturation that has destabilized the subgrade, replacement of that section is usually the honest call. We will show you the photo record and explain the line-item difference before you decide. Call (831) 704-1211 for a written quote either way, estimates are free.

Our Unilock Service Process - Step by Step

1. 1
   Diagnosis with photo documentation. We walk the site, identify the Unilock series and the failure mode, and photograph every condition. You get the photo record before we leave, so you see what we see.
2. 2
   Written scope and flat price. Under Clause 1 of the Haven Standard, we deliver a written quote with line-item costs for base repair, paver reset, replacement, or full installation. No work starts until you have the number in writing.
3. 3
   Repair or install with Unilock-compatible materials. We source the correct edge restraint, polymeric sand, and base aggregate for your Unilock series and Campbell’s clay-soil conditions. If permits are required, we pull them.
4. 4
   Compaction, leveling, and joint activation. We re-compact the base in lifts, set the pavers to grade with proper pitch for drainage, and activate the polymeric sand so joints lock without washing out.
5. 5
   Final walk, photo record, and warranty. We walk the finished work with you, deliver the final photo documentation, and back the job with our 365-Day Done Right Promise. If it is not done right, we make it right.

Unilock Products We Service & Install in Campbell

We work with Unilock Brussels Block, Beacon Hill, Umbriano, and Copthorne pavers. Brussels Block is the workhorse for Campbell driveways, its tumbled finish forgiving on older slabs that are not perfectly flat. Beacon Hill works well for patios where a smoother, more contemporary surface is wanted. Umbriano suits pool decks and modern installations, though it needs honest conversation about sealer maintenance in high-UV exposure. Copthorne delivers the old-world look for accent borders and courtyards. We stock Unilock-compatible edge restraints, polymeric sand, and base aggregates locally for fast turnaround on repairs.

We Also Service These Brands

Rowan Construction Group Campbell sources across fifty-plus vetted brands. In related trades we install KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, and Kohler and Toto fixtures. Our paver work also covers Belgard and Techo-Bloc systems. Multi-brand depth means the written quote uses honest numbers, not inflated single-source pricing.

FAQs - Unilock Construction Service in Campbell

Can you install Unilock Brussels Block or Beacon Hill on a Campbell driveway with the clay soil we have here?

Yes, we install both series regularly in Campbell, and we build the base specifically for this soil. That means excavating to the correct depth, laying geotextile fabric to separate the native adobe clay from the permeable aggregate base, and compacting the base in lifts so it does not settle when the clay swells. The pavers themselves are not the issue, the base preparation is. Call (831) 704-1211 and we will walk your driveway and show you what the base should look like.

Why is my Unilock Umbriano patio getting chalky and faded?

The chalky appearance is surface oxidation and UV degradation of the cement paste at the exposed-aggregate face, often accelerated by pool chemical splash or sprinkler overspray. It is cosmetic, not structural. We assess whether a color-enhancing sealer restores the depth or whether the surface is too far gone. In Campbell’s sun, unsealed Umbriano on a south-facing pool deck typically needs attention every three to five years. Call (831) 704-1211 for an exact assessment, estimates are free.

Do you only install Unilock, or can you match the Unilock pavers already on my property?

We are an independent contractor, not a Unilock-exclusive installer. We can match existing Unilock pavers where the series and color are still available through regional distribution, and we can blend Unilock with Belgard or Techo-Bloc where a customer wants mixed materials. We will verify availability before quoting so you do not get a mismatch. Call (831) 704-1211 to schedule a look.

What does it cost to replace a Unilock paver driveway compared with sealing it?

Sealing is maintenance, not repair. If your base is sound and your pavers are flat, sealing protects the surface and refreshes color. If you have heaving, joint loss, or edge failure, sealing wastes money on a surface that will keep moving. We will tell you which category you are in. Call (831) 704-1211 for a written quote.

My Unilock pavers are heaved and the polymeric sand is gone - can you fix just that section?

Often yes. If the heave is localized and the pavers are not cracked, we lift the affected field, re-grade and re-compact the base, reinstall the pavers with fresh polymeric sand, and blend the repair. If the heave is widespread or the base is saturated from a drainage problem, partial repair will not last. We photograph the conditions and give you both options with prices. Call (831) 704-1211 for an exact quote, estimates are free.

Is Rowan Construction Group Campbell authorized by Unilock?

No. We are an independent Unilock service provider, not affiliated with or authorized by Unilock. Our expertise comes from years of field installation and repair work with Unilock products across the South Bay, not from a manufacturer certification. We use Unilock-compatible OEM-style materials and quality aftermarket products where appropriate, and we disclose which is which.

Do you use genuine Unilock/OEM parts?

We use Unilock-compatible edge restraints, polymeric sand, and base aggregates that meet or exceed OEM specifications. For sealers and cleaners, we use quality aftermarket products where the chemistry is equal or better. We do not claim parts are genuine Unilock when they are not, and we itemize materials on every written quote.

How long does Unilock service take?

A localized repair, lift-and-reset on a heaved section typically takes one to two days. A full driveway replacement with proper base excavation and compaction takes three to five days, plus cure time for any concrete curb work. Permitted jobs in Campbell add time for structural evaluation if your home’s cripple wall triggers seismic review, which is common on pre-1975 construction. We build that timeline into the written scope.

What Unilock models/series do you cover?

We service and install Unilock in Los Gatos and Campbell, including Brussels Block, Beacon Hill, Umbriano, and Copthorne pavers. We do not work with every Unilock product line, and we will tell you upfront if your series is outside our current inventory or expertise.

Will service void my Unilock warranty?

Unilock’s warranty terms apply to manufacturing defects and are separate from installation or service work. As an independent provider, our service does not activate or void any manufacturer warranty. We document our work with photos and written scope so you have a record if a manufacturing claim ever arises.

How much does Unilock construction cost in Campbell?

Paver driveway installation runs $7,000-$18,000, paver patio installation $3,500-$11,000, driveway replacement $5,000-$14,000, and driveway sealing $250-$700. Exact cost depends on square footage, base condition, access, and whether permits or seismic evaluation are required. We deliver a flat written price before any work starts.
