We’re not a manufacturer-authorized dealer, and we don’t pretend to be.

Call (833) 400-1314 for a free estimate on any Unilock patio, driveway, or wall project in Campbell.
Why Campbell Residents Choose Us for Unilock Service
Unilock makes a well-engineered product, but the install determines whether it holds. We’ve spent years working with Brussels Block, Beacon Hill, Richcliff, and Seneca across Campbell’s 1950s through 1970s tract homes, and we’ve learned where the system fails when local conditions get ignored. Noel Carvalho, our owner and general contractor, grew up in Gilroy watching his father patch their family home on weekends, then studied construction technology at Gavilan College before spending two decades running builds across Santa Clara County. That background shows up in how we approach Unilock work in Campbell: we spec base depth for adobe clay, pre-screen for orchard roots, and use Unilock sales & service standards that respect both the manufacturer’s specifications and Campbell’s design review process. One contractor, every phase, from excavation to polymeric sand.

Common Unilock Construction Problems We Solve in Campbell
Each of these failures appears in Campbell with a specific local trigger. Here’s what we regularly correct:
- Efflorescence on Brussels Block pavers: Campbell’s wet winters push water through older slab-on-grade yards with poor drainage, leaving chalky white mineral deposits on the paver surface. It’s cosmetic but persistent, and scrubbing alone won’t stop it until the drainage underneath is addressed. We re-grade where needed and clean with a proper efflorescence remover before re-sanding.
- Settling and shifting of Beacon Hill pavers over adobe clay: Adobe clay expands when wet and shrinks when dry. If the base wasn’t compacted to spec, Beacon Hill pavers will dip and separate within two winters. We remove the affected section, excavate deeper, and re-compact with the correct aggregate before resetting.
- Joint sand erosion in Richcliff patios: Winter rain in Campbell washes standard joint sand out of Richcliff’s tighter joints, and once the sand goes, weeds and paver movement follow. We replace with Unilock polymeric sand, which sets firm and holds through the next wet season.
- Frost heave and root intrusion under Seneca wall blocks: Frost heave is rare in Campbell, but it can happen. More common: mature orchard tree roots pushing against Seneca wall blocks installed too close to a heritage oak or walnut. The wall leans, the block cracks, and the repair requires a root barrier, not just re-stacking.
- Paver discoloration from hard water irrigation: Campbell’s tap water runs hard, and older ranch homes often have irrigation systems tied to the same supply. Over time, calcium deposits dull the surface of Unilock pavers. We clean and seal where appropriate, but we’ll tell you plainly if a sealant isn’t worth the cost on your particular project.
Unilock Service in Campbell: What Local Conditions Mean for Your Equipment
Campbell’s heritage tree ordinance is the one thing generic contractor pages never mention, and it changes how Unilock projects get started here. If a mature orchard tree sits anywhere in your proposed patio or driveway footprint, city hall can halt excavation until the tree is assessed and protected. That’s not a bureaucratic formality; it’s a work stoppage with real scheduling and cost consequences. We routinely bring an arborist to pre-screen Unilock projects before we break ground anywhere in Campbell, because we’d rather spend a few hundred dollars on an assessment than lose two weeks waiting on a permit. In the Orchard City neighborhood, we once hit old orchard roots and a pocket of adobe clay after excavation on a Brussels Block patio. Our tech adjusted the base depth, installed a root barrier, and re-compacted to Unilock specs, and the crew finished with polymeric sand. That patio survived the next winter’s rains without settling. Good construction doesn’t need a sales pitch – the work explains itself.
Unilock Models & Products We Service in Campbell
We install and repair the main Unilock product families: Brussels Block, Beacon Hill, Richcliff, and Seneca. For repairs on existing installations, we use Unilock OEM joint sand and base materials to maintain warranty compliance. When a paver line has been discontinued and only a few units are damaged, we source quality aftermarket matches that blend visually and perform comparably. Our stance is simple: if the existing base is structurally sound and only a handful of pavers need replacing, we’ll always recommend repair over a full tear-out. That’s the difference between a contractor who installs Unilock and one who understands the whole system from excavation to jointing.

AfterUnilock Service Pricing in Campbell
Here are the price ranges we quote for Unilock work in Campbell. These reflect typical project scopes for the city’s ranch homes and larger lots, not bargain-basement installs that skimp on base preparation.
| Service | Price Range (Campbell, CA) |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the price: access to your yard, whether we hit adobe clay or roots requiring extra excavation, the square footage of the project, and which Unilock line you choose. A Beacon Hill driveway on a flat Campbell lot will run lower than a Richcliff patio that needs a root barrier and re-grading, similar to what we see with Saratoga Unilock service pricing. Every free estimate includes a written line-item breakdown, so you’ll see exactly where the money goes. Call (833) 400-1314 to schedule yours.

FAQs – Unilock Construction in Campbell
Yes, it very likely will if a mature tree stands within the project footprint or its root zone. Campbell’s ordinance requires assessment and protection for heritage trees before excavation. We bring an arborist to pre-screen your site during the estimate phase, which avoids permit delays later. Call (833) 400-1314 and we’ll check your property’s tree situation before you commit to anything.
Adobe clay expands and contracts with moisture, which means a shallow or poorly compacted base will move under your pavers within a season or two. We excavate deeper than the minimum spec, use the correct aggregate, and compact in lifts until the base is stable. Skimping on this step is the most common reason Unilock patios and driveways fail in Campbell. For an exact assessment of your yard’s soil and what it means for base depth, call (833) 400-1314.
Sometimes, but it depends on the condition of the concrete. If the slab is cracked, spalling, or has drainage issues, overlaying pavers will trap those problems underneath and the new surface will fail. If the concrete is sound, we can overlay with proper edging and a drainage plan. We’ll tell you honestly which path makes sense after inspecting your driveway. Estimates are free at (833) 400-1314.
Brussels Block holds up well in Campbell’s climate because its textured surface provides traction when wet and its dense concrete resists the calcium deposits from hard irrigation water. Richcliff is also a solid choice for patios where you want a tighter joint. The best paver depends on your specific yard conditions, drainage, and how you use the space. Call (833) 400-1314 and we’ll walk you through the options with Campbell’s climate in mind.
After the rainy season, inspect your joints for sand erosion and refill with Unilock polymeric sand before weeds establish. Clean efflorescence with a proper remover if white deposits appear, and address any low spots where water pooled. A spring inspection costs less than a summer repair. We offer maintenance visits for Unilock installations across Campbell, so call (833) 400-1314 to schedule one.
