Why Tiburon Residents Choose Us for Unilock Service

We’ve installed Unilock pavers on Tiburon’s steep, tight hillside lots for years, from permeable driveways off the Old Rail Trail to retaining walls above downtown. That local reps and field time matters because Unilock’s product line is deep, and what works on a flat Marin County lot will not hold on a 10% grade with wind-driven rain hitting it all winter. We’re an independent Unilock service provider, not authorized or partnered with the manufacturer. That independence means we specify the right Unilock product for your slope, not the one a dealer is pushing. Glen Sorrento grew up in the Shell Cove neighborhood of Foster City and studied building construction technology at College of San Mateo before spending two-plus decades working through nearly every project type the Peninsula throws at a contractor. He’ll tell you straight: “Let’s figure out what the job actually needs – then we’ll talk materials.”

Common Unilock Construction Problems We Solve in Tiburon

• Base erosion and settling on steep grades – On Tiburon’s hillside streets, an improper open-graded base or missing geogrid lets Unilock pavers shift downhill after heavy rain, especially where runoff concentrates. We excavate to stable subgrade and rebuild the base properly. No shortcuts.
• Edge restraint failure – Without properly anchored edge restraints, paver courses creep on slopes. This is common on driveways above downtown where grade exceeds 10%. We install Unilock’s own edge restraints, anchored to spec.
• Joint sand washout – Wind-driven rain off the bay strips joint sand from Unilock surfaces, leading to loose units and weed growth if polymeric sand wasn’t used or was improperly installed. We re-sand with the correct polymeric product and address drainage so it doesn’t happen again.
• Efflorescence and paver spalling – Freeze-thaw is rare in Tiburon, but marine moisture and clay soils cause efflorescence and spalling on older Unilock lines not rated for wet/dry cycles. We can clean, repair, or replace affected units depending on coverage.
• Drainage failures behind retaining walls – Estate Wall and other Unilock wall systems fail fast in Tiburon when weep holes clog and hydrostatic pressure builds. We rebuild with proper backfill, geotextile, and drainage stone that handles hillside runoff.

Unilock Service in Tiburon: What Local Conditions Mean for Your Equipment

Because Tiburon’s hillside streets above downtown and along the Old Rail Trail are so narrow and steep that concrete trucks and even standard flatbed deliveries often can’t reach the site, Unilock paver projects here are routinely staged from a street-level drop and hand-carried or conveyor-belted up the hill. That single fact changes the entire project plan. The base design must account for limited compaction access, so we often spec a deeper open-graded base with geogrid rather than relying on heavy plate compactors in tight spots. Product choice shifts too. Smaller-format Unilock units like Brussels Block or Thornbury are far easier for a compact carrier to handle on a hillside than large-format slabs. If you live on one of those narrow upper streets, your real cost is often decided by how materials get up the hill, not by the paver price per square foot.

Unilock Models & Products We Service in Tiburon

We work with the Unilock lines most common in Tiburon: Brussels Block for driveways and walkways, Beacon Hill for a more contemporary finish, Thornbury for a tumbled look that suits older cottages and hillside homes, and Estate Wall for retaining walls and terraces. We use Unilock’s own edge restraints, joint sand, and geogrid where specified, but base materials come from local Marin suppliers: Class II road base and geotextile. No off-brand pavers. If your existing Unilock surface is failing only in isolated areas, we’ll repair and re-set those units. If more than 30% is shifting or spalling, we recommend full replacement with a properly engineered base. For broader Unilock product questions, see our Unilock sales & service page.

FAQs – Unilock Construction in Tiburon

Can Unilock pavers be installed on a steep Tiburon driveway without sliding?
Yes, if the base is engineered correctly. We install geogrid, a deeper open-graded base, and anchored edge restraints rated for slopes above 10%. That combination holds pavers through heavy rain. Call (833) 589-8103 for an on-site assessment.

How do you handle deliveries and staging for a Unilock project on a narrow hillside street?
We stage pallets at street level and hand-carry or conveyor-belt them up to the site. It’s slower labor, but it works where trucks can’t reach. We will not risk a flatbed on a road it cannot safely navigate.

Do I need a permit for a Unilock paver driveway or patio in Tiburon?
Often yes. Tiburon’s design review and geological scrutiny are strict, and permeable surfaces may be required depending on your lot’s runoff profile. We handle the permit paperwork and Marin County submittals as part of the job.

What Unilock products work best for fire-resistant landscaping in Tiburon’s WUI zones?
Unilock concrete pavers are inherently non-combustible, which is a real advantage in wildfire-interface areas. We spec permeable Unilock lines for driveways and patios to help with defensible space and drainage compliance.

How long does a Unilock paver installation take on a typical Tiburon hillside lot?
Most driveways run five to ten working days depending on access and slope. Patios are usually three to five. The staging on a steep street is what adds time. We’ll give you a schedule with the estimate. Call (833) 589-8103.
