Unilock Construction in South San Francisco, CA | Gold Star Contractors
We install, repair, and rebuild Unilock paver driveways, patios, and retaining walls across South San Francisco. As an independent Unilock service provider, not a manufacturer-affiliated dealer, we track both current and discontinued Unilock lines so we can match your existing hardscape when a repair is needed. What separates paver work in South San Francisco from inland Bay Area cities is the fog-belt marine air and steep Westborough hillsides, which change how base prep, edge restraint, and joint sand must be specified. Call (833) 382-8544 for a free Unilock estimate in South San Francisco.
Why South San Francisco Residents Choose Us for Unilock Service
We have installed Unilock pavers on hundreds of South San Francisco properties, from hillside lots west of El Camino to tenant improvements along the industrial corridor, and we offer Broadmoor Unilock service as well. Our crew has a working knowledge of Unilock’s Brussels Block, Brussels Dimensional, Beacon Hill, and Eco-Optiloc lines, and we know which edge restraints and joint sands OEM spec calls for on sloped or vehicular applications. Noel Carranza, our owner and general contractor, grew up around Anaheim tract homes being renovated block by block, studied construction technology at Fullerton College, and spent his twenties on concrete and finish carpentry before building this operation. He carries that same hands-on, no-drama approach into every South San Francisco paver job we take on. One call, done right, that’s the only way he knows how to run a job.
We also understand the city’s permitting culture. South San Francisco reviewers look closely at drainage and hardscape coverage, and we prepare plans that address both before the first shovel hits. Our team handles Unilock sales & service with the same discipline we bring to full remodels and exterior systems.

Common Unilock Construction Problems We Solve in South San Francisco
- Joint sand washout and efflorescence on north-facing slopes. Fog-belt moisture on shaded Brussels Block patios, especially under redwood canopies, keeps joints from ever fully drying. The result is white mineral bloom and sand loss that invites weed growth and paver movement. We excavate, re-sand with Unilock polymeric joint sand, and correct any drainage that keeps water trapped against the surface.
- Edge restraint failure on sloped driveways in Westborough and the hills west of El Camino. Winter runoff finds the paver perimeter quickly. When the OEM restraint fails or was never installed, lateral creep begins and the driveway starts walking downhill. We rebuild the perimeter with Unilock OEM edge restraints, never generic substitutes on vehicular or sloped runs.
- Base settlement over undocumented fill or old concrete on pre-1950s bungalow lots. South San Francisco’s west-of-El-Camino housing stock includes small-lot bungalows built before modern grading standards. What looked like a flat driveway often hides buried concrete or loose fill. We see lippage, ponding, and ghost lines where old slabs telegraph through. The fix is over-excavation, geotextile, and re-compaction in lifts, then re-laying salvaged pavers.
- Permeable paver clogging on Eco-Optiloc in industrial-adjacent areas. Airborne dust from logistics yards and biotech construction settles into permeable joints and cuts infiltration rates. We clean and restore the open-graded base, or recommend a traditional paver where runoff quality and maintenance reality don’t support permeable.
- Retaining wall leaning or bulging on steep side-yard terraces. Hillside lots in Westborough often stack terracing, and older Unilock walls without proper drainage behind them start to lean within a decade. We rebuild with geogrid, clean drain rock, and weep holes sized for South San Francisco’s winter rain.
Unilock Service in South San Francisco: What Local Conditions Mean for Your Hardscape
South San Francisco sits directly in the fog belt of the San Bruno Gap. Marine air pours through from the Pacific, and combined with winter rain, it keeps paver base and bedding sand damp far longer than in inland Bay Area cities. That is the single most important local factor in how we build Unilock installations here. We schedule base compaction and paver laying in the same dry window to prevent the sand from pumping under load. On shaded north-facing slopes, we use open-graded base instead of dense-graded aggregate so water never gets trapped and freezes the system into heave. A paver job in South San Francisco is engineered differently than one on a flat inland lot, and the difference shows up in edge restraint, joint sand selection, and drainage detail. This is not a generic paver install market, and the Unilock work we do across South San Francisco service area reflects that.
In Westborough, a homeowner on a steep lot off Westborough Boulevard had a 20-year-old Brussels Block driveway creeping downhill and ponding at the garage apron. We found the original base had been laid over fill without geogrid and the edge restraint was spalling. We removed the pavers, over-excavated eight inches, installed geotextile and geogrid, re-compacted in lifts, and re-laid the salvaged Brussels Block with new OEM edge restraint and polymeric joint sand. The driveway now drains to the street and has held through two rainy seasons. That is the standard we bring to every hillside job in South San Francisco.
Unilock Models & Products We Service in South San Francisco
We work with the Unilock lines most common on South San Francisco properties. Brussels Block and Brussels Dimensional show up on older driveways and patios throughout the Westborough hills and the bungalow streets west of El Camino. Beacon Hill and Eco-Optiloc appear on newer builds and some commercial frontages. Our stance on parts is simple: we use Unilock OEM edge restraints, joint sand, and geotextile on warranted installations, and we will not substitute generic restraints on sloped or vehicular applications. When existing pavers are sound, we re-base and re-sand rather than replace. When settlement or restraint failure is widespread, we recommend full tear-out and rebuild. We keep the common OEM edge restraint profiles and polymeric sands on hand for fast South San Francisco turnaround, and we source discontinued paver colors directly through Unilock channels when a match is required. For properties nearby, we also provide Unilock repair in Daly City.ed.

FAQs – Unilock Construction in South San Francisco
In most South San Francisco cases, yes, especially when the driveway slopes, drains to the street, or changes hardscape coverage area. The city’s planning and building staff review drainage and site coverage closely, and a paver driveway that alters runoff can trigger their review. We pull permits on every job that needs one and handle the submittal, corrections, and inspection coordination. Call (833) 382-8544 and we will tell you whether your specific project needs a permit.
The fog belt keeps base and bedding sand damp for longer stretches than inland cities, which means compaction timing and base gradation have to be right or the system will pump and settle. We schedule compaction and paver laying in the same dry window, and on shaded north-facing slopes we use open-graded base to keep water moving through rather than sitting in the system. This is the single biggest difference between South San Francisco paver work and the same job in a drier inland location.
Yes, in most cases. We track Unilock’s current and discontinued lines, including Brussels Block and Brussels Dimensional, and we source discontinued colors directly through Unilock channels. When the existing pavers are structurally sound, we re-base, re-sand, and re-lay them, only adding new pavers where needed. If the line is still available, we match it precisely. Call (833) 382-8544 with your paver photos and we will identify the line before we set foot on site.
On Westborough hillside lots, the usual culprits are undocumented fill or old concrete under the base, missing geogrid, failed edge restraint, and drainage that runs under the paver perimeter and erodes bedding sand. The fix is never just adding more sand. We over-excavate, install geotextile and geogrid where the slope demands it, re-compact in lifts, and rebuild the edge restraint with Unilock OEM material. Call (833) 382-8544 for a free assessment if your pavers are creeping or ponding.
They can be, but the airborne dust from logistics yards and active biotech construction settles into the joints and reduces infiltration over time. Eco-Optiloc works well on residential lots away from heavy dust sources, but near the industrial frontage we typically recommend a traditional paver with proper drainage unless the owner is committed to regular joint cleaning. We will tell you honestly which system fits your site.
