Unilock Construction in Mountain View, CA | San Mateo Construction
We handle Unilock repair in Los Altos and Mountain View, including paver driveways, patios, and retaining walls, and the one thing that sets our work apart here is how we deal with this city’s clay-heavy soil. Unilock systems fail in Mountain View for predictable, local reasons: bad drainage, thin base layers, and unpermitted past work. San Mateo Construction is an independent Unilock service provider, not affiliated with or authorized by Unilock. If you’re in 94035, 94039, 94040, or 94041 and need Unilock work quoted or repaired, call (855) 901-7266.
Why Mountain View Residents Choose Us for Unilock Service
We’ve rebuilt Unilock installations across Mountain View and Los Altos Hills Unilock service areas long enough to know what works in this soil and what doesn’t. Our crews have pulled apart failed paver driveways in 94041, rebuilt retaining walls in the 94040 hills, and leveled patios in the 94043 flats. Noel Carrington, who leads our San Mateo Construction team, grew up just over the county line in San Mateo’s Baywood neighborhood, where he spent weekends as a kid pouring concrete footings with his father. That early education in drainage and compaction still informs how we approach every Unilock job. We’re not tied to Unilock, which means we can be honest with you. Genuine Unilock pavers and wall units for repairs, yes. But we also specify aftermarket base aggregates and polymeric sands that perform better than the bargain stuff in Mountain View’s clay. We’ll tell you when a repair makes sense and when it’s time to replace.

Common Unilock Construction Problems We Solve in Mountain View
- Uneven settlement under Unilock Brussels Block pavers. Mountain View’s clay soil expands and contracts through winter rain and summer drought. When the base under a Brussels Block driveway is too thin, the pavers lippage, ponding follows, and the surface starts to look wavy. We pull the pavers, rebuild the base to a proper depth, and reinstall with edge restraints that hold the pattern.
- Lateral creep on sloped Unilock Beacon Hill driveways. The hilly sections of 94040 and 94041 see driveways gradually march downhill when the original base wasn’t compacted correctly. Waves form, joint sand washes out, and the driveway loses its crisp lines. We re-compact and sometimes re-grade before reinstalling the Beacon Hill units.
- Unilock Estate Wall failures from trapped water. Retaining walls on Mountain View lots fail when downspouts and surface flow concentrate behind the wall. No drainage, no wall. We add clean stone backfill, perforated pipe, and proper weep holes so hydrostatic pressure doesn’t push the wall over.
- Efflorescence and color fade on Unilock Lineo pavers. The whiteness you see on pavers isn’t damage; it’s mineral salts pulled up by winter rain and left behind by summer drought. Sealing gets neglected, fade sets in. We clean and seal Lineo pavers so they hold their color, and we explain which sealers make sense for Mountain View’s UV exposure.
- Sunken pavers near garage aprons and foundations. Time after time, we find old Unilock driveways settling right where homeowners back out every day. The edges drop, water runs toward the house, and the foundation gets wet. Fixing this before it becomes a structural issue is the kind of proactive call we recommend.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
There’s a particular issue we run into in the older 94041 blocks that you won’t see written about in Unilock’s catalogs. Homeowners buy a 1950s rancher, start planning a kitchen addition, and when the city of Mountain View comes out to review the property, they find unpermitted past hardscape work: a failing retaining wall buried under ivy, a patio poured without permits, a paver driveway that was never signed off. We’ve corrected these before. In fact, we were called to a 1950s rancher in the 94041 ZIP after the homeowner noticed their Unilock Brussels Block driveway sinking near the garage. We pulled the pavers, found the original base was only 2 inches of gravel over clay, and rebuilt it with 6 inches of compacted aggregate and a drainage channel before reinstalling the Unilock pavers with fresh edge restraints. The driveway now sheds water away from the foundation and has survived two winters without movement. That’s the Mountain View reality: your Unilock investment doesn’t get to be pretty until the underlying work passes inspection and handles water correctly. A lot of what we do is fixing what someone else did wrong before we ever lay a new paver.
Unilock Models & Products We Service in Mountain View
We work with the Unilock lines that show up most often in Mountain View: Brussels Block for driveways and walkways, Beacon Hill for its larger format and flagstone look on sloped lots, Estate Wall for retaining and garden walls, and Lineo for a cleaner, modern paver profile on patios. For repairs, we use genuine Unilock pavers and wall units to match existing color and texture. The one place we deliberately step away from Unilock specs is base aggregates and polymeric sands. The aftermarket products we stock perform better in clay-heavy, wet-winter conditions, and they’re what we keep on hand for fast turnaround on Mountain View jobs. If you want an honest repair-versus-replace assessment, that’s exactly what we give. Especially when a failed wall or driveway is threatening the integrity of what’s next to it. We also bring the same level of care to Unilock sales & service across the broader Bay Area, so what we learn in Mountain View’s soil gets applied everywhere we work.

FAQs – Unilock Construction in Mountain View
They sink because Mountain View’s clay soil moves more than most people realize. Winter rains swell the clay, summer drought shrinks it, and if the base under the pavers is too thin or wasn’t compacted properly, the pavers follow the movement. The fix is a properly built base: usually 4 to 6 inches of compacted aggregate, sometimes with a drainage layer depending on the site. Call (855) 901-7266 if your pavers are moving, and we’ll tell you what your base actually needs.
Yes. We use genuine Unilock Brussels Block pavers for repairs so the color and texture match what’s already on your property. Where existing pavers have faded from Mountain View sun, we’ll also talk through whether cleaning and sealing the whole surface makes sense so the new pavers don’t stand out. Call (855) 901-7266 for an exact match quote.
Sometimes. The City of Mountain View’s Community Development Department reviews hardscape work on a case-by-case basis, and a paver driveway that changes your impervious surface area or grading can trigger a permit. We’ve also seen unpermitted past hardscape work block new permits until it’s corrected. We’ll tell you upfront what’s likely to require a permit and we pull permits for projects that need them.
They handle it well if the drainage is right. Winter rain pushes water into the base and behind walls; summer drought dries the soil and the pavers. The two cycles together are hard on a poorly built base, which is why proper base compaction and drainage come first on every Unilock job we do in Mountain View. Sealing also matters for Lineo pavers, since wet-dry cycles accelerate efflorescence and color fade.
Unilock Brussels Block is the most common choice for flat driveways in 94043 because it handles vehicle weight well when the base is correct. Beacon Hill also works if you want a larger format with a flagstone look. The product matters less than the base underneath it. We’ll help you choose between the two based on your driveway’s slope and sun exposure. Call (855) 901-7266 to talk it through.
