Unilock Construction in San Bruno, CA | Spruce Contractors
We provide independent Unilock paver and retaining wall installation across San Bruno as a San Bruno General Contractor, and the one thing that sets our work apart here is that we treat every project as a foundation job first. San Bruno sits inside the San Andreas Fault zone, and hilly lots with short cripple-wall homes mean a paver system has to respect drainage and base compaction in ways most pavers don’t. If you’re planning a Unilock driveway, patio, or wall in the 94066, call Nate Calloway and the Spruce Contractors crew at (877) 265-5771 for a free, itemized estimate.
Why San Bruno Residents Choose Us for Unilock Service
We install Unilock segmental pavers and retaining-wall systems as an independent hardscape contractor. That independence matters more than most homeowners realize. Because we’re not manufacturer-affiliated, we can speak plainly when a failed paver field is the fault of the base, not the product. Our crews work directly from Unilock’s own installation specs, including base compaction in lifts, polymeric joint sand, and proper edge restraint on every San Bruno job. Nate grew up in Hillsborough, spent years in the field around San Mateo County, and understands which hillside lots fight you and which materials make it through wet Bay winters. With more than 50 name-brand manufacturers across our trades, Unilock is one tool in a deep kit, not a sales script. For full Unilock sales & service depth, we know the product lines and the failure points.

Common Unilock Construction Problems We Solve in San Bruno
- Paver spread-out at driveway aprons. San Bruno’s clay soils hold water through winter, saturate the base, and let the field walk outward at unsupported edges where a rusted or missing edge restraint gives way. We pull the affected rows, reset the restraint, and recompact.
- Polymeric joint sand washout and rutting. This shows up on driveways cut into sloped lots where an under-compacted base was laid too thin. The pavers are fine; the base is the problem. We lift, re-base in lifts, and re-sand.
- Efflorescence and moss on shaded north-facing patios. San Bruno’s fog belt keeps exterior hardscape damp for months. White mineral bloom and green algae aren’t product defects. We clean, address the drainage, and re-sand with a proper poly.
- Retaining wall blockface separation on hillside cuts. Missing geogrid and inadequate drainage backfill let walls bulge outward. In a fault-zone city, that’s a structural concern, not a cosmetic one.
- Base settlement around older raised foundations. When a paver patio sinks near a 1940s or 1950s San Bruno home, the cause is often decades of drainage running against the perimeter. We regrade, redirect, and rebuild the base.
Unilock Service in San Bruno: What Local Conditions Mean for Your Equipment
San Bruno sits directly on the San Andreas Fault zone. The 1940s to 1960s ranch homes and stucco tracts that dominate the housing stock were built on raised foundations with cripple walls that are often only 18 to 24 inches tall and packed with original diagonal sheathing. Any paver driveway or patio we build has to keep its base and drainage clear of that perimeter foundation rather than piling soil and runoff against it. In the Lomita Park area, for example, we pulled up a Brussels Block driveway that had spread two inches at the street apron because the old base was under-compacted and the edge restraint had rusted through. We excavated to depth, re-compacted in lifts, reset the Unilock units with new edge restraint, and tied drainage away from the low cripple-wall foundation that the owner’s retrofit inspector had flagged. That’s where San Bruno hardscape work differs from surrounding areas like Unilock service in Millbraeg cities: the foundation is always part of the paver conversation here.
Unilock Models & Products We Service in San Bruno
We regularly install and service Brussels Block, the tumbled dimensional paver that fits San Bruno’s ranch-era streetscape. We also work with Cambridge Pavingstones with ArmorTec for a stockier, harder-wearing surface, Beacon Hill Flagstone for irregular flagging patios that suit the coastal-fog palette, and Brussels Dimensional wall units for low landscape walls. For repairs, we use Unilock’s own paver and wall units and matching edge restraints so the system performs as designed, and quality aftermarket polymeric sands and geogrid where the spec allows. We stock common Brussels Block units locally for fast San Bruno turnaround, which cuts lead time on repair jobs, unlike our Unilock service in Brisbane.

FAQs – Unilock Construction in San Bruno
Yes, if the base and drainage are set up correctly. We keep the compacted base graded away from the foundation perimeter and direct runoff to a proper outlet, so you don’t add hydrostatic pressure against an older cripple wall that’s already on a fault zone. Call (877) 265-5771 and we’ll walk the site with you before quoting.
Nearly always, the edge restraint failed or was never installed, and the base absorbed enough winter moisture to let the field spread. The pavers themselves are usually fine. We reset the edge, pull and recompact the affected area, and re-sand. Call (877) 265-5771 and we’ll confirm what’s happening on you driveway.
No. Shaded north-facing patios in San Bruno’s fog belt can hold moisture for months, which invites moss and efflorescence on any paver surface. We clean the field, fix the underlying drainage, and re-sand with a polymer that resists washout. Call (877) 265-5771 for a site check and a quote.
Most walls over three feet, and many shorter ones, do need geogrid layers and drainage backfill on sloped San Bruno ground. This isn’t optional in the fault zone. We spec geogrid per Unilock engineering guidance and never skip it to save a few hundred dollars on a wall that’s holding back a hillside. Call (877) 265-5771 for a wall assessment.
Sealing only helps if the base is sound. In San Bruno, a driveway that’s rutting, spreading, or settling through the fog season almost always has a base issue, and sealant won’t fix that. If the pavers are in good shape, we lift, re-base, re-lay, and re-sand, which costs less than full replacement. Call (877) 265-5771 and we’ll tell you which path your driveway actually needs.
