Unilock Construction in Tiburon, CA | San Bernardino Contractors
We provide independent Unilock paver and retaining-wall installation and repair across Tiburon – driveways, patios, walkways, and hillside retaining walls. What makes our Unilock work here different is that we plan for Tiburon’s single-lane hillside access and fog-belt moisture before a single paver gets staged. Unilock sales & service is a core part of what we do, and we’ve learned exactly how these systems behave on steep Marin grades. Call (855) 473-5620 to talk through your project and get a free estimate.
Why Tiburon Residents Choose Us for Unilock Service
We’re not a paver installer who picked up the Unilock catalog last spring. We work with the full Unilock line in Tiburon every season — from Marin City Unilock service to local hillside jobs – Brussels Block, Town Hall, Beacon Hill wall block, Cambridge Pavingstones with ArmorTec – and we know how each one performs when cut into a 30-degree hillside or left to sit under a redwood canopy that never dries out. Ruben Castillo, our owner, grew up learning to frame and reroof on a shoestring budget, then took his construction technology training at San Bernardino Valley College. He has spent two decades learning that what matters is not which paver you choose, but what sits underneath it on a sloped lot. We match Unilock line and color blends when we repair, we set proper edge restraint, and we tell homeowners straight when a base has failed and needs a re-do, not a patch. If it’s not built right the first time, you’re just paying for it twice.
We’re an independent Unilock service provider. Not authorized, not sponsored, not warranty-backed by Unilock. That matters because our answer to every question about your pavers is based on what’s actually happening on your lot, not what a manufacturer rep wants you to sign off on. In Tiburon service area work, that independence changes the estimates we write and the fixes we recommend.

Common Unilock Construction Problems We Solve in Tiburon
- Joint sand washing out on steep driveway aprons. Driveways off the Tiburon Blvd corridor pitch hard down to the street, and Marin’s winter rain concentrates runoff into narrow channels. Polymeric sand that works fine on a flat Sonoma lot gets sheared loose in one rainy season here. We re-set joints with a proper polymeric blend and correct the drainage so water goes where you intended, not over the neighbor’s slope.
- Edge restraint failure and paver creep on hillside patios. We regularly see patios with shallow spikes driven into unengineered fill. The downhill edge lets loose, pavers creep a half-inch or more, and joints open in a season. We cut in a pinned concrete curb restraint and compact the base properly before re-laying the Unilock field.
- Efflorescence and moss staining on shaded, north-facing paver fields. Tiburon’s bayside fog belt keeps north- and west-facing pavers damp for months. White mineral deposits surface, moss takes hold in the joints, and shaded retaining-wall faces stay slick. We clean, re-sand, and where needed adjust drainage or canopy to give the surface a chance to dry.
- Base settlement and differential heaving over native clay fill. The original Tiburon hillside builds often set pavers right on native clay without over-excavation. Rocking units, ponding, and a step-off at the driveway or wall transition are dead giveaways. The fix is demolition and base rebuild, not a surface patch – and we’ll tell you that before you spend a dollar.
- Improper Unilock wall drainage on cut slopes. Retaining walls on Tiburon grades hold back water, not just soil. Without proper weep holes and backfill gravel, the wall face stays saturated, stains, and the block can bow. We rebuild with drainage where needed and re-lay the original Beacon Hill block line when the units themselves are still sound.
Unilock Service in Tiburon: What Local Conditions Mean for Your Equipment
Here’s something you only learn by working on Tiburon hillsides, not by reading the Unilock install manual or installing Unilock in Chinatown-style flat lots: the real scope line on most of these projects is drawn before the first paver shows up. Streets off the Tiburon Blvd spine are frequently single-lane with no turnaround at the end. A full Unilock paver bundle and base rock don’t fit on a utility trailer that needs somewhere to turn around, and a concrete truck can’t climb some of these grades. So the staging plan and the haul plan become part of the base design itself. We’ve shuttled Brussels Block pallets from a street-level drop point up a hillside by conveyor because no truck could get within a hundred feet of the pad. We’ve coordinated with neighbors ahead of time to stage material on a flat shoulder, then moved it in phases. If the contractor writing your estimate hasn’t walked the access route and timed the turnarounds, the number they give you isn’t a quote – it’s a guess. Our estimates account for pump trucks, conveyors, and neighbor-coordinated staging because on these lots, those line items are not optional extras.
Unilock Models & Products We Service in Tiburon
We install and repair the full residential Unilock line that makes sense for Tiburon lots. Brussels Block – the tumbled-edge paver that handles driveways, patios, and walkways – is the most common one we see, and we stock matching color blends and repair quantities locally for faster turnaround on Tiburon jobs. Town Hall gives a historic-look tumbled surface for patios and garden walks. Beacon Hill is our go-to tumbled retaining-wall block for hillside terraces. Cambridge Pavingstones with ArmorTec surface protection hold up well on sun-facing driveways. On repairs, we match the original Unilock line and color blend so patches don’t read as patches, and we use Unilock-compatible edge restraint, geotextile, and polymeric joint sand rather than generic substitutes.

AfterUnilock Service Pricing in Tiburon
Pricing in Tiburon reflects the hillside. Jobs here carry site-access and compaction costs that flat-lot projects in Marin never see, so the range is real and the number you get from a drive-by estimate may not be. We line-item everything so you can see where the money goes.
| Unilock Service | Typical Price Range in Tiburon |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives cost on a Tiburon lot is access – how far the material has to travel from the last turn-around, how much over-excavation is needed on the grade, and whether drainage work has to happen before the base goes in. A free estimate from us includes a walk of the access route, not just the pad. Call (855) 473-5620 and we’ll put real numbers on your project.

FAQs – Unilock Construction in Tiburon
Yes, when the base and edge restraint are designed for grade – not just the same flat-lot recipe. A Unilock Brussels Block driveway on a 15-20% slope needs over-excavation, compacted aggregate base, pinned concrete curb restraint on the downhill side, and polymeric joint sand that won’t wash out in the first winter rain. Most heaving and creep we see on Tiburon driveways traces back to someone skipping one of those steps. Call (855) 473-5620 and we’ll tell you honestly what your specific grade needs.
It will, with correct drainage and the right joint treatment. North- and west-facing Tiburon patios hold moisture for months, which leads to efflorescence and moss in the joints. We address that by correcting drainage away from the patio, choosing a polymeric sand suited to damp conditions, and in some cases adjusting canopy to let the surface dry. It’s a site-specific concern, not a product failure – but it’s one a contractor who only works flat dry lots may not plan for.
Many of them do, and in Tiburon, Town of Tiburon and Marin County review requirements can apply depending on wall height, grade, and what’s above or below the wall. We tell you if your wall triggers engineering and permit review, and we won’t lay block against a cut slope without proper drainage behind it. Call (855) 473-5620 and we’ll walk through what your wall actually requires.
We plan the staging and haul route before the base detail is finalized. On Tiburon hillsides off the Tiburon Blvd spine, we’ve run material up by conveyor, moved pallets in phases from a neighbor-coordinated flat shoulder, and designed schedules around turn-around limits. If a contractor’s estimate doesn’t include those line items, it doesn’t include reality. That access plan is built into our free estimate – call (855) 473-5620.
Usually yes, and we match both the Unilock line and color blend so the repaired section doesn’t read as a patch. That said, if the failure is base settlement, re-setting new pavers on top of a bad base is money thrown away – we’ll tell you when the right fix is a base rebuild under the existing units. Call (855) 473-5620 for an exact assessment and quote; estimates are free.
