Unilock Construction in Tiburon, CA | Brookside Contractors
We provide independent Unilock construction service across Tiburon, from paver driveway installations on steep hillside lots to retaining walls that have to hold back Marin County clay. For homeowners in nearby communities, we also offer Marin City Unilock service with the same slope-tested approach. The thing that makes our Unilock work different here is simple: we actually build for Tiburon’s geotechnical reality, not a flat-lot spec sheet. Nate Burrell and the Brookside Contractors crew have been doing hardscape and construction work on slopes like these long enough to know that a patio here is never just a patio. Call (833) 725-3508 for a free estimate on your Unilock project.
Why Tiburon Residents Choose Us for Unilock Service
Unilock pavers and walls show up all over Tiburon, on the waterfront terraces, the hillside driveways, the garden paths cut into slopes with a view of the bay. Homeowners choose them because they look right on a Marin County property and they hold up to the weather, mostly. The catch is that Unilock products need installation that respects local ground conditions, and that’s where we come in. Our crews work with Unilock sales & service specifications every week, trained by Unilock technical reps on proper base compaction, edge restraint, and drainage detailing for sloped applications.
We are not authorized or endorsed by Unilock, and we’ll tell you that straight. We’re an independent Tiburon General Contractor that happens to know these products inside and out because Tiburon keeps us busy with them. When a homeowner calls about a shifted paver driveway or a wall cap that cracked after the last winter storm, we know what we’re looking at before we even park the truck. Nate Burrell grew up watching cheap construction fail early, and he runs this company with the same standard: build it right on the first pass, or you’ll be back to fix it on your own dime.
“Do it once, do it right – everything else is just a future repair bill.” That’s how we approach every Unilock job in Tiburon.

Common Unilock Construction Problems We Solve in Tiburon
- Salt-laden fog and winter runoff corroding edge restraints. This is the big one on Tiburon’s bluff and waterfront lots. Unilock’s steel edge restraints and fasteners take a beating from marine air, and once the restraint fails, pavers start migrating downhill. We replace corroded steel with Unilock’s aluminum restraint, which handles the salt exposure far better, and re-secure the paver field so the driveway or patio stops spreading.
- Clay soils and hillside movement cracking rigid mortars and grout. Marin’s expansive clay expands and contracts with winter saturation and summer drying, and any rigid mortar joint in a Unilock wall cap or step tread will eventually crack. We rebuild those caps with flexible construction joints and proper drainage behind the wall so the structure moves without failing.
- Efflorescence and surface spalling from poor drainage. Where water doesn’t drain off a Tiburon patio or walkway properly, salts migrate up through the pavers and leave that white chalky bloom on the surface. In severe cases the paver faces start spalling. We correct the drainage, clean and seal the units where they’re salvageable, and replace only the ones that are too far gone.
- Base settlement and rutting on steep driveways after heavy rains. Improper base compaction on a slope is a time bomb. The first serious winter storm saturates the base, the fines wash out, and the Unilock driveway pavers rut and settle. We excavate, install a geotextile separator, re-compact the aggregate base in lifts, and rebuild the driveway so it drains instead of eroding.
- Wall cap and step tread failures on hillside terraces. Tiburon’s terraced lots put a lot of load on Unilock Estate Wall and Beacon Hill walls. When caps crack or shift, it’s usually a drainage or freeze-thaw issue combined with grade movement. We rebuild caps with proper slope for runoff and verify the wall’s drainage system is actually working.
Unilock Service in Tiburon: What Local Conditions Mean for Your Equipment
Here’s what separates Unilock work in Tiburon from Unilock in Chinatown or the same job twenty minutes inland in Corte Madera or Mill Valley: Tiburon’s hillside and design-review ordinances often require geotechnical reports for any grading or retaining wall over a certain height. Even a small Unilock patio or driveway project on a sloping Tiburon lot can trigger a soils report and design review that wouldn’t be needed on a flat parcel a few miles east. The town sits on a steep Marin County peninsula where nearly every buildable lot is hillside, waterfront, or bluff-edge, and the permitting process reflects that. A paver driveway off Paradise Drive or a retaining wall on a lot above the Old Rail Trail isn’t just a hardscape job anymore; it’s a geotechnical project with paperwork attached. We’ve navigated enough Tiburon design review and building department submissions to know what questions get asked before they’re asked, and we build our Unilock installations to pass inspection the first time. That means proper drainage design, engineered base depths, and retaining wall construction that accounts for the surcharge load of the slope above it. When you hire us for Unilock work in Tiburon, you’re hiring a contractor who already knows the town’s hillside rules, not one who’s going to learn about them after the permit gets flagged.
Unilock Models & Products We Service in Tiburon
We work with the full range of Unilock hardscape products you’ll find on Tiburon properties. That includes Brussels Block pavers for driveways and patios, Beacon Hill flagstone-style slabs for walkways and pool decks, Estate Wall blocks for retaining structures, and Thornbury pavers for a more traditional look. When a drive or patio needs repair, we assess whether the base and drainage can be corrected and the existing units reused; we only replace spalled or cracked pavers. For parts, we use Unilock’s own edge restraints, polymeric sands, and sealers where specified, paired with quality aftermarket base materials and geotextiles for the structural layers. We keep common Unilock components stocked locally for fast turnaround on Tiburon repairs, so a failed edge restraint doesn’t leave you waiting two weeks while your driveway keeps shifting.

AfterUnilock Service Pricing in Tiburon
Unilock construction costs in Tiburon run a little higher than inland Marin because of the slope work, drainage requirements, and occasional geotechnical review. Here’s what you can expect on the major Unilock project types we handle:
| Service | Price Range |
|---|---|
| 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 the cost on a Tiburon Unilock job is what’s under the pavers: the aggregate base depth, geotextile separation, drainage routing, and whether the slope requires retaining components. A patio on a relatively flat Tiburon lot will land toward the lower end of that range; a steep driveway with corroded edge restraints and a failed base will push toward the top, and sometimes beyond, because the base and drainage rebuild is the actual job. Our free estimate includes a written line-item breakdown so you can see exactly what you’re paying for. Call (833) 725-3508 to schedule yours.

FAQs – Unilock Construction in Tiburon
Do Unilock pavers need special base preparation on Tiburon’s steep hillside lots? Yes, and this is the part most installers get wrong. On slopes greater than about 5%, the aggregate base needs to be thicker than flat-lot standards, compacted in lifts, and separated from the native clay with a geotextile fabric so winter runoff can’t wash fines out and cause settlement. We also add drainage interceptors where needed to keep water from undermining the paver field. If your Tiburon driveway or patio wasn’t built with these steps, it will eventually rut or shift. Call (833) 725-3508 and we’ll take a look.
Can Unilock retaining walls be used on bluff-edge properties in Tiburon? They can, but not as a substitute for engineered slope stabilization. On a bluff-edge or steep hillside lot, any retaining wall above a modest height will likely need a geotechnical design, a permit, and possibly design review. Unilock Estate Wall blocks are fine as the facing product, but the wall’s structural design, drainage system, and foundation have to be engineered for the actual loads and soil conditions on your specific parcel. We handle that coordination as part of the build.
How does salt air affect Unilock pavers and walls in Tiburon? Salt-laden fog accelerates corrosion on steel edge restraints and fasteners, which is a common failure point on Tiburon driveways and terraces. The pavers themselves are concrete, so they’re not corroding, but the steel components holding the edge of the paver field are. We use Unilock’s aluminum edge restraint on Tiburon replacements because it lasts dramatically longer in marine air. Salt can also draw efflorescence up through pavers where drainage is poor. Our fixes account for both.
What’s the typical cost to replace a failed Unilock paver driveway in Tiburon? Most full Unilock driveway replacements in Tiburon land between $5,000 and $14,000, depending on the square footage, slope, and what the base and drainage situation looks like once we excavate. A simple paver re-installation on a sound base is less; a full rebuild with geotextile, new aggregate, and edge restraint replacement is more. Every estimate we give is free and line-itemed, so you’ll know the number before you commit. Call (833) 725-3508 for an exact quote.
Do I need a permit for a Unilock patio or retaining wall in Tiburon? Often, yes. Tiburon’s hillside and design-review ordinances can require geotechnical reports for retaining walls above a certain height, and even a paver patio that changes drainage patterns or involves grading can trigger a permit. A flat-lot patio of modest size with no grading may not need one, but the moment you’re on a slope, adding a retaining structure, or altering drainage, assume the town wants to review it. We pull permits and work with your geotechnical engineer when the town requires it, and we build to pass inspection.
