Unilock Construction in San Francisco, CA | Workshop Contractors
We install and repair Unilock pavers, walls, and driveways across San Francisco, from the flat streets of the Mission to the steep grades of Noe Valley and Bernal Heights. Unilock work here is different because the city’s hills, damp marine air, and retrofitted Victorian foundations create failure patterns you simply don’t see in flatter, drier towns. If you’re planning a paver driveway, patio, or retaining wall in San Francisco, call Noel Figueroa and the Workshop Contractors team at (844) 384-3361 for a free estimate. We are an independent contractor. We’re not authorized, sponsored, or endorsed by Unilock, but we’ve been installing their systems on San Francisco lots long enough to know exactly where they fail and why.
Most of what we do falls under one roof: Unilock sales & service, concrete work, and the excavation and drainage that hardscape on hillsides demands. One contractor. Every trade.
Why San Francisco Residents Choose Us for Unilock Service
We’re a San Francisco General Contractor first, which means we see the whole site, not just the paver layer. That matters on San Francisco’s lot-line Victorians and Edwardians where an Unilock driveway shares edges with foundations, retaining walls, and neighbor party walls. Noel Figueroa grew up around the kind of finish work that holds up under a second look, and he built this company on the idea that framing square, tile that lines up at the grout joint, and a paver base that drains properly are all the same discipline.
Our crews train on Unilock’s current installation guidelines and base-prep requirements. We stock Unilock OEM pavers, caps, and edge restraint locally so color and dimensional consistency stay intact when we repair a section rather than relaying the whole run. When the base is sound, we repair. When the base is shot, we tell you straight and rebuild it. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
We serve San Francisco service area ZIP codes 94111, 94112, 94114, and 94115, and we know the ground in each of them.

Common Unilock Construction Problems We Solve in San Francisco
- Base settlement on sloped lots. Unilock pavers laid over poorly compacted aggregate on San Francisco’s hillside fill shift within a few seasons and create trip hazards. We see this most on driveways where a garage was carved into a slope and the fill was never mechanically compacted.
- Efflorescence and salt staining. The marine layer and fog belt keep pavers damp for weeks at a time, and that moisture pulls mineral salts to the surface as white, chalky blooms. It’s cosmetic, but it looks like the paver is failing. We clean and seal where it makes sense.
- Joint sand loss and weed intrusion. Wind-driven winter rain from the Pacific washes polymeric sand out of exposed Unilock joints, especially on driveways and patios facing the ocean. Once the joint sand goes, weeds get a foothold and the pavers begin to move independently.
- Edge restraint failure at tight side yards. Unilock paver edges without proper restraint against party walls or foundations bulge where there’s no room for lateral movement. San Francisco’s lot-line construction leaves zero tolerance for edge drift.
- Drainage defeats paver base. Fog keeps surfaces damp and winter storms deliver real rain. Without sloped base drains and permeable joints, water pools at garage thresholds and softens the aggregate over time.
Unilock Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s mandatory soft-story retrofit ordinance, Ordinance 66-15, is the defining fact of hardscape work on this city’s older homes. The 1,700-plus pre-1906 wood-frame Victorians and Edwardians that survived the earthquake and fire sit largely on unreinforced brick foundations, and many must now be retrofitted at the street frontage. What that means for an Unilock driveway or walkway is blunt: if you install or repair pavers before the retrofit shoring and foundation work is complete, that new hardscape gets torn out and relaid when the retrofit crew arrives. We sequence Unilock work after retrofit excavation is done, or we phase it so the paver base and edge restraint only go in once the foundation curb is final. In Noe Valley and Bernal Heights, we routinely find that a “two-story” Edwardian is really a one-story over a full-height basement garage carved into the slope, which makes sequencing everything, from shoring to drainage to pavers, the core of a durable job.
Here’s the field example. In Noe Valley, we rebuilt a Unilock Brussels Block driveway for an Edwardian whose garage had been carved into the slope, a typical Visitacion Valley Unilock service scenario. The original pavers had settled because the base sat over uncompacted fill left from the garage conversion. We removed the pavers, re-excavated to proper depth, installed a geotextile and compacted aggregate base, then reset the Brussels Block with Unilock edge restraint pinned into the new foundation curb. The result is a stable, drained driveway that no longer ponds at the garage threshold during winter storms.
Unilock Models & Products We Service in San Francisco
We install and repair the Unilock product lines most common on San Francisco properties: Brussels Block, Beacon Hill, Copthorne, and Lineo. Brussels Block shows up on driveways and walkways for its tumbled, older look that suits Victorian-era streetscapes. Beacon Hill and Copthorne are flagstone-style pavers we see on patios and rear yards. Lineo’s clean, plank-like lines fit more contemporary additions.
For repairs, we use Unilock OEM pavers, caps, and restraint products to maintain color and dimensional consistency. For base aggregates and polymeric sands, we source aftermarket products suited to San Francisco’s damp, seismic conditions. We will always recommend repair over replacement when the base is sound and only surface or joint issues exist, but we’re honest when a failed base on a hillside lot requires partial reconstruction.

What drives the cost in San Francisco is almost always excavation: hillside fill that needs compacting, old brick foundations at the curb line, and tight side yards where equipment has to be staged in the street. A free estimate means we walk the site with you, check the base and drainage, and give you a written line-item quote. No change orders unless we uncover something structurally different from what we discussed. Call (844) 384-3361 to schedule that walk.

FAQs – Unilock Construction in San Francisco
Yes. Steep lots require a geotextile, deeper compacted aggregate base, and often a retaining edge pinned into a structural curb or foundation. We’ve done exactly this in Noe Valley and Bernal Heights where garages are carved into slopes. Call (844) 384-3361 and we’ll look at your grade, drainage, and access before quoting.
It depends on the scope and whether the work connects to a required soft-story retrofit or affects drainage at the property line. San Francisco has strict rules about impervious surface and run-off, and any paver work that ties into a foundation curb under Ordinance 66-15 may trigger plan review. It’s one reason we verify permits before excavation starts. Ask us when you call (844) 384-3361.
That’s efflorescence, mineral salts migrating to the surface because the marine layer keeps pavers damp for long stretches. It’s cosmetic, not structural, but the fix depends on the pavers, drainage, and whether sealing is appropriate. We can clean and assess it in one visit. Call (844) 384-3361 for an evaluation.
If your building is under a mandated retrofit, any hardscape at the street frontage must be sequenced after the shoring and foundation work is complete. Install pavers first and the retrofit crew tears them out. We phase our Unilock work so that never happens. Call (844) 384-3361 and tell us if your building has a retrofit notice; that changes the schedule.
Usually, yes. We keep Unilock Brussels Block, Beacon Hill, Copthorne, and Lineo in our sourcing pipeline, and we order OEM pavers and caps to match your existing color and profile. The limiting factor is whether your original pavers have faded differently than new stock, but we can blend course by course to minimize the line. Bring photos and we’ll tell you honestly what’s matchable.
