Unilock Construction in Sausalito, CA | San Bernardino Contractors
We’re an independent contractor that handles Unilock sales & service, installing and repairing paver and retaining wall systems across Sausalito. The thing that separates our Unilock work here from anywhere else is the hillside: nearly every job off Bridgeway involves staging pallets by crane or hand-carry because trucks can’t reach the lot. If your patio is settling, your driveway is washing out, or your retaining wall units are loosening on a slope, call us at (855) 473-5620 for a free estimate.
Why Sausalito Residents Choose Us for Unilock Service
We know Unilock’s model lines the way a mechanic knows an engine. Brussels Block, Beacon Hill, U-Cara retaining walls, the Elegance porcelain line: if it’s on a Sausalito hillside, we’ve set it, repaired it, or pulled it up to fix what a previous contractor got wrong underneath. Ruben Castillo runs our crews, and he was raised on job sites where shortcuts meant do-overs. He’s spent two decades framing, pouring concrete, and remodeling across California, and that same standard applies to every paver base we compact.
We’re independent. That matters to you because we’re not a Unilock dealer pushing a catalog pattern onto your slope. We select and detail the system to fit the site. If the base is bad, we say so. If the units are still sound, we’ll re-set them rather than sell you a new surface that will heave again in two winters.

Common Unilock Construction Problems We Solve in Sausalito
Here’s what we see repeatedly on Sausalito properties, and what each one actually means for your pavers:
- Joint-sand washout on sloped driveways. Winter rain sheets down hillside streets before it can infiltrate, and the fines in your paver base migrate toward the downhill edge. Units stay sound but start rocking. We see this constantly on steep driveways below Bridgeway. The fix is base re-compaction and drainage, not more sand.
- Efflorescence and green growth on north-facing patios. Marine fog keeps shaded paver fields damp for months, and that chalky white or green film on retaining-wall caps and stair treads is mineral migration and algae, not a product defect. We clean and re-seal, but we also re-grade so water stops sitting on the surface in the first place.
- Corroded edge restraint near the water. Salt spray off the bay eats standard metal edging and polymeric sand binders within a few wet seasons. You’ll see rust staining and loosened restraint long before the pavers themselves fail. We replace with corrosion-resistant trim and matched connectors.
- Base settlement on cut-and-fill grade. Many Sausalito lots are cut into the hill with fill placed decades ago. Pavers laid directly over that fill without proper compaction will pond water against foundation walls and cantilevered decks. This is a base failure, not a paver failure, and it needs a rebuild, not a top dressing.
- Retaining wall movement on steep grades. U-Cara units and other segmental walls shift when the base course isn’t level or the drainage behind the wall is missing. On Sausalito’s 30% grades, that movement shows up fast. We rebuild from the base up with proper geogrid reinforcement and daylighted drains.
Unilock Service in Sausalito: What Local Conditions Mean for Your Equipment
Here’s the local reality most paver contractors from flat-land cities miss: Sausalito’s hillside streets off Bridgeway climbing toward the Golden Gate view are so steep and narrow that we routinely crane or hand-carry Unilock pallets over roofs to reach the work area. That’s not a scheduling footnote; it dictates the whole job. You can’t stage materials at the curb and wheel them back. You can’t run a skid steer up a 35% grade. You plan delivery around crane lift windows, you compact in lifts by hand where machinery won’t fit, and you build the paver base to shed water down a slope rather than sit flat. In Mill Valley, Tiburon Unilock service areas, or Corte Madera, a paver patio is a straightforward flat-lot pour. In Sausalito, the retaining walls and drainage engineering often out-budget the pavers themselves. We bid accordingly, and we schedule accordingly. Ruben grew up doing framing and concrete work on shoestring budgets, and he still applies the same rule to every job: if it’s not built right the first time, you’re just paying for it twice.
Unilock Models & Products We Service in Sausalito
We work across the Unilock line that actually gets installed on Bay Area hillsides: Brussels Block for driveways and patios, Beacon Hill for a smooth flagstone look, U-Cara for segmental retaining walls that handle real grade changes, and Elegance porcelain pavers for rooftop and view-deck surfaces where weight matters. Our approach to parts is straightforward: matched Unilock units and proprietary connectors, never generic substitutes that change the profile. We stock common replacement units for the lines we install most in Sausalito, which means we’re not waiting a week for a pallet when only forty units need swapping.

FAQs – Unilock Construction in Sausalito
Yes, when the base is built for it. The grade itself isn’t the problem; it’s water moving down the slope and finding the downhill edge of your paver field. We install daylighted drains, re-compact in lifts, and use deeper edge restraint on slopes over 15%. Most driveway failures we see in Sausalito are base failures, not paver failures. Call (855) 473-5620 and we’ll tell you what your specific driveway needs.
We crane them over the roof or hand-carry them. On the steep streets off Bridgeway, we routinely schedule a crane for Brussels Block or Beacon Hill pallets because a delivery truck physically cannot turn or stop safely. We factor that lift cost into the estimate upfront, so there’s no surprise later. It’s part of why we do so much work in Sausalito; most contractors who don’t know the hillside will underbid access and then stall mid-job.
That’s efflorescence and algae from marine fog sitting on a shaded surface. Sausalito’s microclimate keeps north-facing paver fields damp for weeks, especially in winter. The chalky white is mineral salt migrating through the concrete; the green is biological growth. We clean it, re-grade so water stops pooling, and apply a breathable sealer that won’t trap moisture. Call (855) 473-5620 for a condition assessment and a quote to fix it right.
Partly. Salt spray accelerates corrosion of metal connectors and edge restraint, but the primary cause of loosening U-Cara units is usually water getting behind the wall with nowhere to drain. We rebuild with proper backfill drainage, geogrid reinforcement at the right intervals, and corrosion-resistant hardware. The wall is a system, not a stack of blocks. If yours is moving, get it checked before the next big winter rain.
Absolutely. About half our repair work in Sausalito involves pulling sound pavers, re-compacting and draining the base, and re-setting the same units. We’d rather do that than sell you a new surface that will fail the same way. If the base is bad, the pavers aren’t the problem. Call (855) 473-5620 for an honest assessment, and estimates are free.
