Unilock Construction in South San Francisco, CA | Workshop Contractors
We install, repair, and rebuild Unilock paver driveways, patios, walkways, and retaining walls across South San Francisco as your trusted South San Francisco General Contractor. Workshop Contractors is an independent Unilock hardscape specialist, not a manufacturer affiliate or authorized dealer, and the one thing that sets our work apart here is that we plan every job around two local realities: marine-layer moisture and Old Town’s famously tight lots. If you’re pricing a paver project or dealing with a settled wall, call (844) 384-3361 for a free estimate.
Why South San Francisco Residents Choose Us for Unilock Service
Unilock makes a genuinely good paver, but a paver is only as good as the base under it. That’s where most South San Francisco installations fall short. We’ve spent years installing Brussels Block, Beacon Hill, Richcliff, and Umbriano across the Peninsula, including Broadmoor Unilock service, and we know how those specific product lines behave when they sit in the fog belt for a decade.
Noel Figueroa, our owner and general contractor, grew up around tradesmen who taught him that a structure is only as honest as its foundation. That applies to a 60-foot retaining wall and a 400-square-foot backyard patio equally. When we take on a Unilock job in South San Francisco, we bring that framing-and-foundation mindset to the base prep, the drainage plan, and the edge restraint. Most paver failures are base failures. We treat the base like the real construction project, because it is.
We also carry Unilock’s own system components – base material, joint sand, edge restraints, polymeric sand – and for older installs we source compatible aftermarket parts that meet or exceed OEM specs. You get honest repair-vs-replace advice, not a sales pitch.

Common Unilock Construction Problems We Solve in South San Francisco
- Joint sand washout and efflorescence on Brussels Block driveways. Persistent coastal fog and winter rain keep paver joints damp for weeks at a time here. When drainage is undersized, the joint sand washes out and white mineral deposits creep up the paver faces. We regrade the base slope, add proper drainage where needed, and rejoint with polymeric sand that actually holds in wet conditions.
- Leaning or settled Beacon Hill retaining walls. Older 1920s to 1960s cottages in South San Francisco often have poor roof runoff and shifting soil. A Beacon Hill wall that was never engineered for the site will start leaning within a few rainy seasons. We rebuild with proper base compaction, drainage gravel behind the wall, and geogrid where the height demands it.
- Moss and algae on Richcliff pavers. In the fog belt, north-facing surfaces stay damp for months. Richcliff’s textured surface is beautiful, but it holds moisture and grows moss under tree canopy or near downspouts. We clean, treat, and often reposition downspout discharge so the problem doesn’t come back in six months.
- Paver edges crumbling on driveways and walkways. Heavy winter rain undermines paver edges where the edge restraint wasn’t set into a concrete collar. This is common on South San Francisco’s older stucco-over-woodframe properties, where the original hardscape was often a weekend project, not a permitted installation. We set a proper concrete collar and haul out the failed base.
- Failed asphalt-to-paver driveway conversions. We see a lot of old asphalt driveways that someone paved over with pavers and called it done. The base was never removed, never regraded, never compacted. It fails. We do the full tear-out, regrade for marine-layer moisture, and build it back correctly.
Unilock Service in South San Francisco: What Local Conditions Mean for Your Equipment
South San Francisco’s small-city building department runs its own permit culture, and Old Town residential lots are frequently too tight for equipment or dumpsters. That means a Unilock paver project here often needs a street-use permit and careful staging, a step that neighboring cities with wider lots and different permit processes don’t require. We plan for that from day one. When we work in Old Town, Avalon, or the neighborhoods west of Highway 101, we know the lots are narrow, the side yards are wheelbarrow-width at best, and the freeway is a few blocks away. Staging across 101 or hauling through the airport-adjacent corridors near SFO changes scheduling. We file the street-use permit, schedule the dumpster, and coordinate the haul route before we ever break ground, whether it’s here or a Unilock repair in Daly City. That’s not a detail. It’s the difference between a job that finishes on schedule and one that sits for two weeks waiting on a permit.
Unilock Models & Products We Service in South San Francisco
We install and repair the full Unilock residential line, but most of our South San Francisco work centers on four product families. Brussels Block is the workhorse for driveways and patios – classic tumbled look, strong enough for vehicle traffic when the base is right. Beacon Hill is our go-to for retaining walls and seat walls, with a split-face texture that reads as stone. Richcliff gives a more contemporary, linear paver with a subtle texture, popular for small patios where a smoother look fits the architecture. Umbriano has a granite-like finish and is often chosen for pool decks and walkways where a refined surface matters. For parts, we use Unilock’s own system components whenever possible to maintain warranty compliance. For older installations, we source compatible aftermarket restraints and drainage parts that meet or exceed OEM specs. We stock common joint sands and edge restraints locally so South San Francisco jobs don’t stall waiting on a parts shipment.

FAQs – Unilock Construction in South San Francisco
Yes, but only when the installation is built for the climate. The fog belt keeps joints damp, so we use polymeric sand that resists washout and we regrade base slopes to move water away from the paver surface. A properly installed Unilock patio or driveway here needs a joint sand top-up every few years, not constant upkeep. If your pavers are growing moss or losing sand every winter, the drainage was never right. Call (844) 384-3361 and we’ll tell you what’s actually going on.
Usually yes. Old Town lots are often too tight for a dumpster on the property, and South San Francisco’s building department requires a street-use permit for staging in the public right-of-way. We handle that filing as part of the project. If a contractor tells you they’ll just park the dumpster in the street without a permit, the city will tag it and you’ll be the one dealing with the notice. Call (844) 384-3361 for an estimate that includes the permit process.
The marine layer mostly affects base compaction and curing. We schedule excavation and base work when the ground has had a chance to dry after rain, because compacting wet soil is a waste of time – the base will settle later. In South San Francisco, that means we sometimes shift a start date by a few days to wait out a wet week. It’s slower, but it’s the reason our pavers stay flat. Call (844) 384-3361 and we’ll give you a realistic window for your specific site.
For a small shady yard, we usually recommend Richcliff or Umbriano. Richcliff’s linear shape makes a narrow space feel longer, and Umbriano’s denser surface resists moss better than more textured pavers. If the yard is north-facing and stays damp, we’ll also recommend a brighter color tone to keep the space from feeling dark. The right choice depends on the specific lot, so call (844) 384-3361 for a free site visit and we’ll show you samples in your actual yard.
Sometimes. If the wall is leaning because of a localized drainage issue and the base is still sound, we can pull the affected section, fix the drainage, and rebuild it. If the base compaction was inadequate everywhere, a partial repair just delays the full failure. We’ll give you an honest assessment either way. Build it right the first time. The second time costs twice as much and nobody’s happy about it. Call (844) 384-3361 for a repair evaluation.
