Unilock Construction in Tiburon, CA | Timberline Contractors
Unilock hardscape in Tiburon is a different animal than it is on a flat lot in Corte Madera. We install and service Unilock paver driveways, patios, and Pisa2 retaining walls across the 94920 ZIP, and the defining factor here is almost always access, not aesthetics. Timberline Contractors provides independent Unilock construction and repair across the Tiburon Peninsula, including Marin City Unilock service, – we’re not manufacturer-affiliated or authorized, which means we’re free to solve your hillside drainage and staging problems honestly. Call (866) 253-5808 for a free estimate.

Why Tiburon Residents Choose Us for Unilock Service
Most paver contractors in Marin know how to lay a Brussels Block patio on a flat backyard. Put that same patio on a Tiburon hillside with no at-grade staging and winter runoff sheeting down the slope, and the whole job changes. We’ve spent enough time on these lots to know that the base is the project – the pavers are just what you see when we’re done. Nelson Fung, our owner and Tiburon General Contractor, learned the trade formally at Los Angeles Trade-Technical College and has been swinging hammers on everything from bungalow remodels to mid-size commercial builds long enough to know where a cheaper shortcut costs twice as much in three years. Do it right the first time or explain yourself twice.
We stock genuine Unilock units, matching edge restraints, and polymeric sand so your segmental system locks together as designed – never mismatched patch pavers that read differently after five seasons of Tiburon fog and rain. And because we’re a full-scope general contractor, we can handle the retaining wall, drainage, and deck work your hillside Unilock project actually needs under one contract. You aren’t coordinating three trades on a steep street where there’s nowhere to park a second truck.

Common Unilock Construction Problems We Solve in Tiburon
- Efflorescence and salt bloom on bay-facing patios. Brussels Block and Beacon Hill Flagstone units on the water side of Tiburon sit in the fog belt, where constant moisture never lets the pavers fully dry out. The white, chalky residue isn’t a paver defect – it’s mineral migration trapped by the marine layer. We clean and re-seal with the right breathable sealer, but we’ll also fix the drainage that’s keeping the pavers wet in the first place.
- Base failure and paver settlement on sloped driveways. When winter runoff sheets down a Tiburon driveway, the base layer takes the hit. Open-graded base without proper edge restraint and poly sand detailing will erode from underneath, and the pavers start to heave and separate. We rebuild the base for drainage first, not just re-set the pavers.
- Pisa2 wall creep on hillside surcharge. A retaining wall on a sloped Tiburon lot holds back more than soil – it holds back the weight of the slope behind it. Without geogrid layered behind the wall, Pisa2 units can bulge or creep outward. We see this on older walls where the original install skipped grid to save money.
- Stained and faded Umbriano faces under cantilevered decks. Drainage from a deck cantilevered over grade dumps dirty runoff straight across the pavers below. Umbriano’s smooth face shows that staining fast. The fix is routing the deck drainage away from the paver field, then cleaning and re-sealing the surface.
- Washed-out edge restraints on steep frontages. Along narrow Tiburon streets, water runs hard along the edge of a paver driveway and eats at the restraints. We repair the edge with genuine Unilock restraints and re-detail the transition so runoff moves past, not through.
Unilock Service in Tiburon: What Local Conditions Mean for Your Equipment
Above the Tiburon waterfront, many lots have no at-grade staging area at all. There’s no flat spot for a pallet of Umbriano, no place to park a plate compactor next to the patio. Unilock pallets and compaction equipment have to be craned or walked down a slope before a single paver is laid. That flips the normal construction sequence: base excavation and compaction get staged around access, not the other way around. On a street off the hillside, we’ve walked every pallet and the compactor down a narrow slope because there simply wasn’t room to stage at grade. It changes how you think about the job. You dig in lifts, you compact in accessible bands, and you schedule material delivery against neighbor access easements and view corridors. A flat-lot paver page never has to wrestle with any of this – which is exactly why the typical Unilock guide falls short for Tiburon homeowners.
Unilock Models & Products We Service in Tiburon
We install and repair the full range of Unilock segmental pavers and retaining systems you’ll see on Tiburon lots: Brussels Block pavers for driveways and patios, Beacon Hill Flagstone for a more natural flagstone look on bayside terraces, Umbriano for smooth, contemporary surfaces, and Pisa2 for retaining walls that have to hold back real hillside surcharge. Our Unilock sales & service work covers both fresh installs and repair of existing systems. We use genuine Unilock units and matching edge restraints and polymeric sand – never aftermarket knockoffs that fade differently or lock poorly. For Tiburon turnaround, we keep common Brussels Block and Pisa2 units accessible locally so repairs don’t wait on a factory order.

FAQs – Unilock Construction in Tiburon
Yes. We routinely walk or crane pallets and compaction equipment down sloped access points when there’s no at-grade staging area – the sequence gets built around the access, not the other way around. Call (866) 253-5808 and we’ll walk your lot to see what staging looks like for your specific site.
That’s efflorescence – mineral salts migrating to the paver surface because the marine fog layer keeps the pavers perpetually damp. It’s not a product defect. We clean it with the right agents, then address the drainage that’s holding moisture against the surface so it doesn’t come back in six months. For a quote on a bayside patio, call (866) 253-5808.
Almost always, yes. The surcharge from the slope behind the wall means the wall is holding back far more lateral pressure than a garden wall on flat ground. Pisa2 walls on Tiburon hillsides should have geogrid layered behind the block to prevent creep and bulging. Call (866) 253-5808 for an assessment before an older wall gets worse.
The base, edge restraints, and surface drainage have to be built for Tiburon’s winter runoff pattern – sheet flow moving downhill fast. We rebuild the open-graded base with proper restraint at the edges and route runoff past the paver field so the base doesn’t erode from underneath. Estimates are free: call (866) 253-5808.
Yes – this is where a full general contractor makes a real difference. We can tie a new patio or paver driveway into our Home Remodeling in Tiburon or a deck cantilevered over grade, handling the drainage, retaining, and hardscape under one contract so you don’t end up with three different crews on a lot that can barely fit one. Call (866) 253-5808 to talk scope.
