Unilock Construction in Lompico, CA | Millwright Builders
Millwright Builders provides independent Unilock paver and retaining wall installation across Lompico, CA, and serves as a Lompico General Contractor. We’re not manufacturer-authorized, and we don’t claim to be. What we do bring is hands-on experience building Unilock driveways, patios, and segmental walls on steep mountain parcels where a flat-lot install would fail inside two winters. Call (866) 925-0334 for a free estimate.
Unilock pavers are one of the better hardscape systems for mountain terrain when they’re installed to the material’s actual engineering requirements. That’s the catch. On a Lompico hillside, the paver itself matters less than what’s under it, what’s holding the edges, and where the water goes. We specify the brand, explain the trade-off, and stand behind the install.
Why Lompico Residents Choose Us for Unilock Service
Noel Castañeda, our owner, did his construction trades training at Skyline College in San Bruno and spent nearly two decades on residential and light commercial work across the Peninsula before founding Millwright Builders. He grew up in Sunshine Gardens in South San Francisco, where he learned early that structures hold because of decisions made before anything gets built. That same instinct drives how we approach Unilock work in Lompico.
We’ve installed Unilock Brussels Block, Beacon Hill Flagstone, Town Hall pavers, and Pisa2 retaining wall systems on lots that would scare off a volume installer. We don’t bid a Lompico job without walking the slope, checking drainage, and looking at access first. Then we tell you what the project actually needs, even if that’s more excavation and a better base than you hoped for. Your paver drive shouldn’t creep downhill because somebody undercut the subgrade to save a day.

Common Unilock Construction Problems We Solve in Lompico
- Paver settlement and creep on steep driveways: Lompico drives run up sloped, private parcels, and when the base isn’t excavated deep enough for the grade, pavers shift under the weight of vehicles and winter runoff. We see stair-step spreading at the edges of drives on Lompico Road and West Lompico Road every season. The fix isn’t new pavers; it’s re-excavation, a deeper compacted aggregate base, and proper edge restraint.
- Joint sand washout and edge failure after heavy rain: Lompico gets serious winter storms that channel water across patios and drives. Without a functional drainage plan and solid edge restraint, joint sand disappears and the perimeter units start wandering. We cut channel drains and set concrete curb restraints to steer stormwater away from the paver field.
- Retaining wall bulge and lean on saturated hillsides: A Pisa2 or similar segmental wall built without geogrid reinforcement and drain rock behind it will eventually lean or bulge on a Lompico slope. The soil here holds water in winter, and hydrostatic pressure does not care how straight the wall looked on day one. On slope-failure walls, we recommend an engineered rebuild, not restacking the same units.
- Surface staining and efflorescence from shade and redwood litter: Constant shade under the Santa Cruz Mountains canopy means pavers never fully dry. Redwood needles, sap, and organic debris stain light-colored Unilock surfaces, and trapped moisture drives efflorescence. We address drainage and surface preparation to reduce staining cycles, and we’re honest about which paver colors hold up better here.
- Failed base under a paver drive that’s been patched before: In a mountain cabin area with older owner-built homes, we regularly find prior work where pavers were laid over a marginal base to save money. The drive looks fine in July and starts sinking by February. Repacking a sunken drive over bad subgrade just buys one more winter. We fix the subgrade first.
Unilock Service in Lompico: What Local Conditions Mean for Your Job
Most Lompico paver jobs are really driveway projects on a slope, which is why Unilock in Mount Hermon faces similar challenges. That’s the sentence that separates our work here from a Unilock install in a flat Bay Area suburb. A Unilock drive off Lompico Road or West Lompico Road needs a deeper compacted base than the standard catalog detail, tighter edge restraint on the downhill side, and a drainage plan that accounts for stormwater running across steep, winter-soaked terrain. The delivery itself can require traffic flagging on a one-lane stretch, and concrete trucks sometimes can’t make the turn at all. We plan logistics and slope work before the first permit is pulled, not after the materials are already on site.
Consider a job we did on a steep private drive off West Lompico Road. We pulled up a heaved paver apron where the old base had been laid too shallow, and water had been running under it for years. We re-excavated to a deeper compacted aggregate base, set a concrete curb restraint on the downhill edge, tied the field into Unilock Brussels Block, and cut a channel drain to steer stormwater off the drive before the winter rains. The client got a driveway that sheds water instead of shedding pavers.
Unilock Models & Products We Service in Lompico
We install and repair the Unilock lines that perform best on mountain terrain: Brussels Block for driveways and high-traffic surfaces, Beacon Hill Flagstone for patios where a more organic flag look suits the property, Town Hall for a cleaner modern layout, and Pisa2 for segmental retaining walls. When Unilock repair in Felton or nearby is needed, we source genuine Unilock units so wall and paver profiles match an existing run exactly. But we’re direct when a failed base or an underbuilt wall is the real problem. No amount of genuine product fixes bad subgrade.
For homeowners exploring Unilock sales & service across the broader region, we recommend starting with a site walk of the actual slope. A catalog photo won’t tell you whether your drive needs retaining or where the stormwater actually goes.

FAQs – Unilock Construction in Lompico
Yes, a Unilock paver driveway can handle a steep Lompico grade when the base is engineered for it. The difference between a drive that lasts and one that creeps downhill is excavation depth, compaction, edge restraint, and drainage, not paver brand. We design for slope before we lay a single unit. Call (866) 925-0334 if you want us to look at your specific grade.
Sinking and spreading at the edges almost always means the base was too shallow or the edge restraint failed, and Lompico’s winter runoff made it worse. Water gets under the pavers, the subgrade softens, and the edges start to wander. Repacking the sand won’t stop it; the fix is re-excavation and a proper restraint system. Call (866) 925-0334 for a site evaluation and quote.
We coordinate it. On the narrow stretches of Lompico Road and its side routes, a full paver or concrete delivery can require traffic flagging, advance scheduling, and sometimes a smaller truck or staged transfer. We plan that before the permit gets pulled, not after materials arrive. It’s one of the reasons we walk every Lompico site before quoting.
Often yes, and that’s a structural question before it’s an aesthetic one. A patio cut into a Lompico slope usually needs some retained earth above or below it, and a segmental wall like Unilock Pisa2 requires geogrid and drain rock to hold up to saturated winter soil. We’ll tell you if the job genuinely needs a wall and design it with drainage built in.
A properly built one will. Lompico’s winter storms are the immediate test; a well-drained, deeply based paver drive sheds water and survives. Wildfire requirements affect the edges of the project, including defensible space and sometimes access dimensions, so we build those considerations in from the start. Call (866) 925-0334 for an exact quote that accounts for all of it.
