Unilock Construction in San Bruno, CA | Milpitas Construction
We install and repair Unilock paver driveways, patios, and retaining walls throughout San Bruno as an independent contractor. What makes our Unilock work different here: we know that most mid-century San Bruno lots sit on saturated, clay-heavy subgrade and that seismic retrofit work often means pulling up a perfectly good paver field just to let foundation crews access the perimeter. Call (877) 752-4194 for a free Unilock estimate in 94066.
As a full-scope general contractor, we spec materials by name across 50+ brand product lines, and Unilock is one of the paver systems we trust for Peninsula driveways and patios. We are not a Unilock dealer, and we are not manufacturer-authorized. We buy through distributors, which means our loyalty is to the homeowner and the long-term performance of the install, not to a badge. When you hire us for Unilock construction in San Bruno, you get one accountable team from base course to final polymeric sand, backed by our own workmanship on every lift, lay, and re-sand.
Why San Bruno Residents Choose Us for Unilock Service
Unilock pavers are only as good as what sits under them. Ken Stafford, owner of Milpitas Construction, grew up in this part of the Bay Area and has spent decades watching mid-century Peninsula lots punish shallow base courses and lazy edge restraints. He and our crews know exactly which Unilock lines hold up on fog-soaked, wind-blasted San Bruno lots, and we specify our own compacted Class II base, aluminum edge restraints, and polymeric joint sand underneath every paver. That is where a Unilock install actually lives or dies here.
Beyond the product knowledge, San Bruno homeowners keep calling us because we are already working in 94066 on the exact housing stock that defines the city: 1960s and 1970s ranch-style homes with small lots, post-and-pier foundations, and drainage that fights back every winter. We are not driving in from another county or over from Unilock service in Millbrae to guess at your subgrade. We have already repaired, relayed, or rebuilt paver work on your neighbors’ streets, and we know what the soil has been doing to those base courses for fifty years.

Common Unilock Construction Problems We Solve in San Bruno
- Joint sand washout and edge restraint failure. Heavy winter rain on sloped San Bruno driveways pushes water through the paver surface faster than standard joint sand can hold. Without solid aluminum edging, pavers migrate toward the street and the whole field starts to rut. We re-sand with polymeric product and install proper restraints so the system drains without pulling apart.
- Efflorescence on Brussels Block and Beacon Hill pavers. This is not a cleaning problem you can ignore. The chalky white bloom comes from moisture migrating up through the compacted base on clay-heavy Peninsula soil, carrying soluble salts that deposit on the paver face. We see it constantly on San Bruno lots where the base was never built for the actual groundwater behavior underneath it.
- Overloaded Thornbury retaining walls. A lot of 1960s San Bruno lots were graded on the cheap, and the original grade change was never engineered for what a modern retaining wall has to hold. Wall lean, bulging courses, and tie-backs pulling out of the soil are the usual signs. We rebuild the wall with proper drainage behind it, because no block holds when water is pushing from the back.
- Heaving and lippage near garage aprons. We run into this a lot in the neighborhoods just west of SFO, where the frost-free climate does not mean the subgrade is stable. Saturated, poorly drained soil underneath a thin base lets pavers shift and lift, and you feel the lip every time you pull into the garage. The fix starts below the surface, not on top of it.
- Driveway settlement after seismic retrofit access. This is the San Bruno-specific one. When a foundation contractor bolts and braces a mid-century home, the perimeter often needs a paver field lifted and set aside. We do that lift, protect the pavers, and relay them onto a recompacted base after the inspection, so homeowners are not paying for a brand-new driveway just because a retrofit truck needed room to work.
Unilock Service in San Bruno: What Local Conditions Mean for Your Equipment
Here is the thing about San Bruno that no generic Unilock page is going to tell you. Your city sits directly on the San Andreas fault zone near Crystal Springs Reservoir, and the retrofit permit volume here, foundation bolting, cripple-wall bracing, soft-story upgrades on 1960s apartment buildings, is a defining part of the local construction calendar. That means Unilock in South San Francisco and San Bruno crews are routinely called into the same tight mid-century lots twice: once to lift and relay a driveway or patio apron so a foundation contractor can access the perimeter footings, and again after the bolting inspection to reset and re-sand the pavers. A paver driveway in this city is not just a surface, it is an access panel for seismic work, and the way it is built has to survive being opened up and put back without losing its grade, its drainage, or its edge restraint. If your base was compacted properly the first time, the re-lay is quick and clean. If it was not, the retrofit is when you find out.
On a split-level ranch in the Crestmoor area off Crestmoor Drive, our crew found a Brussels Block driveway where the original base had settled and joint sand had washed out after a wet winter, leaving a lip at the garage apron. We lifted the field, re-compacted a proper Class II base with new edge restraints, and relayed the same Unilock pavers, then re-sanded with polymeric joint sand so the next rainy season runs off instead of pooling. The homeowner got the original stone back at a fraction of a full replacement, something we also handle with Unilock repair in Pacifica.
Unilock Models & Products We Service in San Bruno
We work with most Unilock paver and wall lines you will find on Peninsula driveways, patios, and garden walls. Brussels Block shows up on a lot of tumbled, traditional San Bruno driveways and walkways. Beacon Hill Flagstone is the large-format slab look we see on patios where homeowners want a smoother, more modern surface. Thornbury tumbled wall block is common on lot-line retaining walls and planter borders. And for drainage-sensitive driveways, Unilock’s Eco-Priora permeable line is a real option worth looking at when a property sits low on its lot or the city flags runoff during a remodel. Our approach is simple: we source genuine Unilock units for the visible surface, and we specify our own compacted Class II subbase, polymeric joint sand, and aluminum edge restraint because those are the parts that decide whether the install still looks level in five years. We stock common joint sand, edge restraint, and base materials locally for faster San Bruno turnaround. If your existing Unilock surface is sound and only the base or joints have failed, we lift, re-base, and relay instead of pushing a full replacement. That is the difference between fixing the problem and just selling you new stone.

FAQs – Unilock Construction in San Bruno
Yes. A paver driveway on a fault-zone lot is not just a cosmetic surface, it is the access path for any future foundation bolting or retrofit work. We build every San Bruno Unilock driveway with a properly compacted Class II base, solid edge restraints, and a joint sand system that can be lifted and relayed cleanly if a seismic contractor ever needs to reach the perimeter footings. If you want a driveway that can be opened up and put back without losing its grade, call (877) 752-4194 for an estimate.
Efflorescence is moisture moving up through the base and depositing salts on the paver surface. San Bruno’s fog and winter rain, plus the clay-heavy soil under a lot of homes, create exactly the conditions for it. The bloom itself is usually cosmetic and often weathers off, but when it keeps coming back, it usually means the base is holding water. We can assess whether you need a drainage correction or simply a base rework, not just a surface cleaning.
Yes, and we do it regularly. If the Unilock units themselves are intact and the problem is a settled base, washed-out joints, or failed edge restraint, we lift the field, re-compact the base, reset the same pavers, and re-sand with polymeric joint sand. The patio looks right and drains right for a lot less than a full replacement. Call (877) 752-4194 and we will tell you which path makes sense for your lot.
A Unilock paver driveway in San Bruno typically runs $7,000 to $18,000 depending on size, slope, and subgrade correction. That is more than asphalt, but pavers hold up better on the clay-heavy, saturated Peninsula lots and they are far easier to lift and relay when seismic work needs access. Concrete runs $4,500 to $12,000, but it cracks and it does not forgive poor drainage the way a properly built paver base does. Call (877) 752-4194 for an exact quote on your driveway.
It will hold if it is built for the water behind it and the soil under it, not just the height of the wall. We see plenty of old grade changes in San Bruno that were never properly engineered. We rebuild with proper drainage rock, a perforated pipe where needed, and a base that handles what the slope actually puts on the wall. The block is the face of the system, not the system.
