Unilock Construction in Ben Lomond, CA | Millwright Builders
We install and repair Unilock paver driveways, patios, and retaining walls across Ben Lomond, CA as an independent contractor – not a Unilock dealer or authorized shop. What makes our Unilock work different here is simple: we design for slopes, saturated winter soils, and post-CZU-fire rebuild requirements that flatland paver jobs never face. If you’re planning a Unilock driveway, patio, or segmental wall on a hillside parcel in the 95005 ZIP, call (866) 925-0334 for a free estimate.
Why Ben Lomond Residents Choose Us for Unilock Service
Unilock pavers are only as good as the base beneath them. That’s the whole story. On a steep Ben Lomond lot, the base is everything – water wants to run, soil wants to move, and a patio laid over native dirt without drainage will heave within two winters. We’ve spent years laying Unilock sales & service work on the mountain grades and saturated hillsides that define this area, and we’ve learned what fails so we build what doesn’t.
Noel Castañeda, our owner, came up doing residential construction on the Peninsula before founding Millwright Builders, and he’ll tell you the same thing he tells every Ben Lomond homeowner: the paver is the part you see, but the base, the drainage, and the geogrid are the parts that matter. We spec the brand, explain the trade-off, and stand behind the install. For Unilock in Lompico and Ben Lomond, that means a compacted aggregate base deep enough for the grade, a perforated underdrain where runoff concentrates, and joint sand that stays put through atmospheric-river storms.

Common Unilock Construction Problems We Solve in Ben Lomond
- Heaved and rocking pavers on sloped driveways. When water migrates under Unilock pavers during winter storms, the base washes out and individual units start to rock under truck tires. On Ben Lomond grades, this happens fast if the original install skipped drainage. We pull the field, rebuild the base, and reset the pavers with proper slope drainage.
- Polymeric sand erosion and joint washout. Ben Lomond’s heavy rain concentrates runoff in channels, and where unlined slopes feed water across a patio, the joints open and pavers shift. We re-sand with a high-performance polymeric joint sand and, where needed, regrade or add sub-surface drainage so the washout doesn’t return.
- Efflorescence and surface staining on wet-cast pavers. The maritime fog belt keeps things damp, and where drainage is poor, water sits against wall faces and paver surfaces, leaving white mineral deposits. We clean the surface and correct the drainage so the staining stops recurring.
- Bulging or toppling segmental walls. A U-Cara retaining wall built without geogrid or drainage aggregate on a tall Ben Lomond slope is a wall waiting to fall. We see this often – walls that look fine for a season or two, then start to lean after a wet winter. We rebuild with proper geogrid placement, drainage rock, and a filter fabric detail that keeps fines from clogging the system.
- Fire-hardening retrofit gaps after the CZU Lightning Complex rebuild. Where the 2020 fire burned through Ben Lomond, old hardscape was often removed and replaced piecemeal. We see paver edges and wall units that don’t meet current ignition-resistant detailing requirements, and we correct those transitions so the rebuilt hardscape aligns with the home’s defensible-space plan.
Unilock Service in Ben Lomond: What Local Conditions Mean for Your Equipment
Ben Lomond sits on steep, unincorporated Santa Cruz County parcels where almost every Unilock driveway or retaining wall needs a geotechnical detail and a CAL FIRE defensible-space review folded into the same permit. That’s not true in Felton, it’s not true in Scotts Valley, and it’s absolutely not true on a flat lot in San Jose. Here, the slope drainage and the fire-hardening clearances drive the paver layout. A driveway that looks straightforward on paper may need a retaining edge, a French drain, and a fire-resistant vegetation buffer – all specified in the same permit set before a single paver goes down. We’ve built Brookdale Unilock service driveways and patios on hillside parcels above Ben Lomond where the geotechnical review flagged soil that couldn’t hold a standard 4-inch base, and we thickened the section and added geogrid to keep the surface stable. If you’re planning Unilock work on a Ben Lomond slope, expect the permit process to ask more of the design – and expect us to answer with an engineered base, not a guess.
Unilock Models & Products We Service in Ben Lomond
We work with the full range of Unilock residential product lines, including Brussels Block, Brussels Dimensional, Beacon Hill, and the U-Cara retaining wall system. For Ben Lomond paver installations, we source genuine Unilock units for color and dimensional matching, so if you’re adding to an existing patio or replacing a damaged section, the new pavers blend with the old. We pair Unilock units with quality base aggregate, geogrid, and polymeric joint sand – the components that actually determine whether a wall or driveway survives a mountain winter. Where a Unilock wall or patio has failed only at the base or joints, we rebuild the base and reset the same pavers rather than replace the field. We replace units only where they’re cracked, spalled, or discontinued and no longer available.

AfterUnilock Service Pricing in Ben Lomond
Paver work in Ben Lomond costs more than the same square footage on a flat lot, and that’s because of what’s underneath. Here are the price ranges we quote for Unilock work in this area:

| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What moves the number within those ranges comes down to site conditions: slope steepness, access for equipment, whether we’re cutting into native rock or fill, the depth of base aggregate needed, and the drainage detail. A free estimate includes a site walk and a written line-item scope. Call (866) 925-0334 for an exact quote on your Ben Lomond property.

FAQs – Unilock Construction in Ben Lomond
Yes – when the base is right. A Unilock paver driveway on a Ben Lomond slope will hold through heavy winter rain if it’s built over a deep compacted aggregate base with a perforated underdrain and geogrid reinforcement. What fails here is not the paver; it’s the base beneath it. Built to the material’s standard, not just to code, a Unilock driveway will stay put. Call (866) 925-0334 for a site assessment and a firm number on your project.
In most cases on steep unincorporated parcels in Ben Lomond, yes – and Santa Cruz County will tell you that before we even get to the wall design. Walls over a certain height, or walls supporting a driveway or home setback, trigger a geotechnical review. Even when it’s not required, on a tall slope we’ll recommend one because a wall without a soil analysis is a wall built on assumptions.
Yes. Unilock pavers are non-combustible and typically work well in the ignition-resistant zones around a home, but the placement matters – a paver patio that extends toward wildland vegetation may need a break in the form of a rock or concrete buffer. We coordinate the paver layout with the defensive-space plan, so your hardscape doesn’t undercut your fire clearance. We’re happy to walk your Mount Hermon Unilock service or Ben Lomond lot and show you what’s feasible.
In most cases, yes. If the pavers themselves are intact – no cracking, no spalling, no fading beyond normal – we pull them, rebuild the base, address the drainage, and reset the same units. You keep the look you chose and lose the heave and the rocking. We replace only where pavers are damaged or no longer available to match.
Drainage is the cost variable. On a Ben Lomond hillside, you’re paying for a thicker base, a perforated underdrain, possibly geogrid, and more excavation and material hauling due to limited access. A flat-lot driveway might run $7,000 to $10,000; a steep Ben Lomond driveway with drainage and retaining edges often lands at $12,000 to $18,000. The estimate will show you exactly where the money goes. Call (866) 925-0334 and we’ll put a firm number on paper.
Yes. For any Unilock wall or driveway on a steep Ben Lomond parcel, we handle the Santa Cruz County permit submittal and coordinate with CAL FIRE and the geotechnical consultant as needed. Permits are part of the scope, not an add-on surprise. You shouldn’t become a project manager; that’s why you hire a general contractor.
