Unilock Construction in Felton, CA | San Bruno Construction
Unilock construction work in Felton means hillside hardscaping that has to survive heavy winter rain, redwood litter, and wildfire-defensible-space rules all at once. We’re San Bruno Construction, an independent contractor offering Felton General Contractor services throughout the Santa Cruz Mountains, and we install and repair Unilock paver patios, driveways, and retaining walls on the steep, fire-prone terrain most flatland crews never see. Call (866) 472-1908 for a free estimate on your Unilock project in Felton.
Our Unilock work here isn’t theoretical. We’ve pulled apart failed paver fields on Felton slopes, rebuilt bases that were never compacted right, and re-set units that crept downhill after one wet winter. And we’re not authorized by Unilock. We’re independent, which means we tell you what actually works on your parcel, not what a factory brochure says should work.
Why Felton Residents Choose Us for Unilock Service
Noel Carvalho grew up on El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before a single tool comes out of the truck. Over two-plus decades running residential projects across San Mateo County and into the Santa Cruz Mountains, including Unilock service in Lompico, he’s seen what happens when hillside hardscaping gets installed on the cheap. Felton homeowners call us because we know the difference between a Unilock field that’ll hold for twenty years and one that’ll heave by spring.
We carry the full Unilock model range for this region and source genuine units when a repair calls for a color and dimensional match. But we don’t blindly follow factory spec on base material or drainage. On Felton slopes, we spec open-graded aggregate that moves water away from the structure instead of trapping it. That one decision prevents most of the wall bulging and paver spreading we’re called to fix.

Common Unilock Construction Problems We Solve in Felton
- Retaining wall bulging from clay backfill. Felton hillsides hold water all winter. When a Unilock Pisa2 wall gets backfilled with native clay instead of free-draining aggregate, hydrostatic pressure pushes the face outward. We see this on nearly every older wall we inspect.
- Polymeric joint sand washing out on downhill driveways. Surface water sheets fast across Felton’s steep grades after heavy rain. Joint sand re-cures brittle and erodes at the toe of the slope, leaving units loose and rattling.
- Efflorescence staining from redwood litter and well water. Light-colored Brussels Block and Beacon Hill pavers pick up tannin stains from redwood debris and mineral deposits from private well water. The result is a chalky, blotchy surface that regular cleaning won’t fix.
- Paver edge-restraint failures on cut-and-fill terrain. Older owner-built patios in Felton often sit on under-compacted bases. The field creeps and spreads at the edges, especially where the hillside was cut and filled decades ago.
- Heaved and sunken paver sections after burn-scar runoff shifts. Parcels affected by the CZU Lightning Complex fire now channel water differently. A Unilock patio or driveway is often the first hardscape to reveal the new drainage path.
Unilock Service in Felton: What Local Conditions Mean for Your Equipment
Much of Felton sits on burned or deforested CZU Lightning Complex slopes where uphill drainage was permanently altered. That changed hydrology shows up first in hardscaping. A Unilock patio or driveway here is often the first place you’ll see how runoff now channels across a parcel after the canopy is gone. The water takes the path of least resistance, and that path frequently runs right under a paver field or into a retaining wall’s backfill. Add Cal Fire WUI defensible-space clearances on top, and you’ve got a second constraint: pavers or plantings tight against the house may not pass inspection. On some Felton parcels, that means rethinking where a paver field can legally go at all. A contractor who’s never worked burn-scar terrain won’t know to check for either issue before breaking ground. We do.
Unilock Models & Products We Service in Felton
We work with the core Unilock lines that hold up best in the Santa Cruz Mountains: Brussels Block for driveway and patio fields, Beacon Hill Flagstone for larger-format patio work, Pisa2 for segmental retaining walls, and Copthorne for an Olde English style on period-appropriate Felton cabins. For repairs, we source genuine Unilock units and manufacturer-recommended polymeric sand and edge restraint so color and dimensional match stays clean. For base aggregate and drainage, we spec open-graded material appropriate to your specific slope. There is no aftermarket substitute for the paver itself. When the field is sound, we re-set, re-sand, and rebuild the base. When units are cracked from subsurface movement, we replace only the affected area rather than ripping out the whole field.

FAQs – Unilock Construction in Felton
That depends on placement. Cal Fire WUI code restricts combustible materials and certain plantings within the defensible space zone around structures. Non-combustible pavers are generally fine, but where they sit relative to the house and surrounding vegetation matters. Call (866) 472-1908 and we’ll assess your parcel before you commit.
Bulging comes from hydrostatic pressure behind the wall face. Native clay backfill holds water, and on saturated Felton slopes that pressure pushes the wall outward. The fix is excavating, installing a free-draining aggregate backfill and proper drainage plane, then rebuilding.
Most Felton parcels fall under unincorporated Santa Cruz County jurisdiction, not the city. That means county permitting and potentially WUI review, depending on scope and location. We handle the paperwork as part of the job. For our full service area details, see the Felton service area page.
Yes, if the base is graded right and the sand is properly activated. On steep grades, we typically add a slight crown or swale to slow surface water and reduce erosive force at the toe of the slope. Where water concentrates, even the best polymeric sand will eventually wash out.
Redwood litter leaches tannins that stain light-colored Unilock units, and mineral-rich well water leaves a chalky efflorescence when it dries. Neither damages the paver structurally, but both change the appearance. We can recommend sealing options that slow staining without trapping moisture. Call (866) 472-1908 for a walkthrough.
