Unilock Construction in Tiburon, CA | San Bruno Construction
We provide independent Unilock paver and retaining wall construction across Tiburon, CA, and the one thing that separates our work here from a flat-lot install is slope. Tiburon is a steep-hillside peninsula town, and most Unilock projects we build require geotech input, shoring, and drainage planning before the first paver gets set. San Bruno Construction handles that full scope, from site prep to final polymeric sand. Call (866) 472-1908 for a free estimate.
Why Tiburon Residents Choose Us for Unilock Service
We’ve been setting Unilock pavers on Tiburon’s tight, view-oriented lots long enough to know that the base matters more than the paver, which is why our Home Remodeling in Tiburon always starts with proper prep. A Brussels Block driveway on a 2% grade in Mill Valley behaves differently than the same product on a 30% Tiburon hillside. Noel Carvalho, our owner, trained in construction technology at Skyline College and has spent over two decades running residential projects across San Mateo County, including plenty of Unilock installations where slope creep and hydrostatic pressure were the real opponents. We’re an independent contractor, not a Unilock dealer, so our recommendations are based on what holds up on Marin hillsides, not what a manufacturer wants moved. We coordinate excavation, drainage, and installation under one contract, so you’re not juggling a paver crew, a drain guy, and a geotech consultant.

Common Unilock Construction Problems We Solve in Tiburon
- Polymeric joint sand washing out on steep driveways. Unilock’s polymeric sand is a good product, but on Tiburon’s winter-saturated slopes, water moves fast. If the base isn’t graded to shed water or the edge restraints aren’t anchored, the sand loosens and pavers start migrating. We reset the field, correct the drainage, and re-sand with Unilock’s own joint compound.
- Base settlement on hillside patios. A surprising number of Tiburon homes sit on old undocumented fill. A patio that looked flat for a decade starts sinking when winter rains finally reach the fill layer. We excavate to competent soil, rebuild the aggregate base in lifts, and compact properly instead of throwing more sand at the problem.
- Retaining wall block facing spalling or cracking. Unilock Estate Wall and Town Hall blocks are solid, but hydrostatic pressure behind a wall that wasn’t drained will crack or push the facing. We install perforated drain pipe, gravel backfill, and sometimes a geogrid tieback before rebuilding the wall. Skipping that step is how walls fail twice.
- Paver surface staining and efflorescence. Tiburon’s damp, tree-canopied north slopes keep pavers wet. That white mineral bloom isn’t a defect, it’s moisture wicking through the block. We address the source with better drainage and air movement, then clean and reseal where appropriate.
- Driver apron damage from delivery trucks. A fully loaded paver delivery truck can crack a driveway apron on a steep Tiburon street. We stage at the bottom and bring material up with a compact crawler carrier, which adds time but prevents a repair bill that eats your budget.
Unilock Service in Tiburon: What Local Conditions Mean for Your Equipment
Here’s the thing most Unilock literature won’t tell you: Tiburon’s hillside streets are narrow, steep, and often shared. A semi with a full pallet delivery can’t always turn around, and even if it can, the weight can destroy a driveway apron or a neighbor’s retaining wall. So we stage pallets at the bottom of the street and shuttle them up with a compact crawler carrier. It adds a day to the front end of a project, but it prevents two days of repairs at the back end. Off Lyford Drive, we rebuilt a failing Unilock Brussels Block drive that had settled and shifted after years of runoff from an uphill neighbor’s slope. We regraded the base, added a concealed channel drain, and reinstalled the pavers with Unilock edge restraints and polymeric sand. The result handled the next winter’s storms without movement. That’s the difference between installing pavers and getting Sausalito Unilock service on a Tiburon hillside.
Unilock Models & Products We Service in Tiburon
We work with Unilock’s most common residential lines: Brussels Block for driveways and patios, Estate Wall and Town Hall for retaining walls, and Beacon Hill for a tighter, more formal look. When a wall or patio fails, we assess whether the base and drainage can be corrected. If the pavers themselves are sound, we repair and reset rather than replace the entire field. We use Unilock’s own system components – their polymeric sand, edge restraints, and wall connectors – because mixing aftermarket parts on steep slopes often leads to joint failure or wall movement. For Tiburon homeowners, that means one supplier with one warranty chain instead of a patchwork of parts. Unilock sales & service is what we do, and we keep common components moving through our inventory so a repair doesn’t wait on a back-ordered part from the Midwest.

AfterUnilock Service Pricing in Tiburon
Unilock work in Tiburon costs more than flat-lot work elsewhere, and the reason is the slope. You’re paying for geotech review, shoring, drainage, and often a crawler-carrier delivery. Here are our current market-calibrated ranges:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every estimate includes a site walk to check slope, drainage, and access. We’ll tell you straight if your project needs a geotech report or a retaining wall before pavers make sense. Call (866) 472-1908 and we’ll give you a written line-item quote, not a ballpark guess.

FAQs – Unilock Construction in Tiburon
Yes. Tiburon runs its own planning and design review with coastal and hillside overlays, so even a driveway re-pave can trigger architectural scrutiny that a flatland city wouldn’t apply. We handle the permit path and know what the review board flags, which saves you a month of back-and-forth. Call (866) 472-1908 for a free estimate and we’ll walk you through what your specific street requires.
We stage pallets at the bottom of the hill and shuttle them up with a compact crawler carrier. It’s slower, but it protects your driveway apron and your neighbor’s retaining wall.
Sometimes, if the grade is moderate and the soil is stable. But on most Tiburon lots, or when doing Unilock in Chinatown with similar grades, once you’re past a certain pitch, you need a wall or you’re fighting gravity. We’ll tell you honestly which one applies.
We typically run 6 – 8 inches of compacted aggregate on driveways and 4 – 6 on patios, plus a proper drainage layer. Undocumented fill often needs deeper excavation. It’s the base, not the paver, that keeps things flat after a Marin winter. Call (866) 472-1908 and we’ll give you a straight answer for your specific site.
Polymeric sand isn’t structural. On a steep pitch with moving water, it can wash out if the base isn’t graded and the edge restraints aren’t anchored. We fix the drainage and the restraint system, then re-sand. The sand isn’t the problem, the water is.
