Unilock Construction in Colma, CA | Gold Star Contractors
We install and repair Unilock pavers, walls, and hardscapes throughout Colma, from dealership frontages on Junipero Serra Boulevard to cemetery walkways and columbarium surrounds, and also offer Unilock service in South San Francisco. What makes our Unilock work different here is simple: we build for the fog. Colma’s damp marine air, wind-driven moisture, and commercial-heavy building stock create paver failures you won’t see in Sunnyvale or San Jose. Call (833) 382-8544 for a free estimate.
Why Colma Residents Choose Us for Unilock Service
Most contractors in Colma don’t think much about what happens to a paver three years after installation. We do, because we’ve seen what this town’s fog does to the wrong base, the wrong joint sand, the wrong edge restraint. Noel Carranza, our owner, spent years on job sites across California learning how water moves through a hardscape before it ever shows up as a crack or a sunken path. That’s the difference between a paver job that looks good for one summer and one that still holds level after five fog seasons.
We’re an independent Unilock contractor. We are not authorized by Unilock and we don’t claim to be. What we offer instead is hands-on experience with their product lines and an honest assessment of what works in Colma’s specific conditions. We use Unilock sales & service knowledge built from real installs and repairs across the Peninsula, not from a brochure.

Common Unilock Construction Problems We Solve in Colma
- Efflorescence on Brussels Block and Beacon Hill pavers. Colma’s summer fog keeps north-facing and shaded surfaces damp for weeks at a time. That persistent moisture pulls salts to the surface, leaving white chalky staining that generic cleaners won’t touch. We strip, neutralize, and reseal those pavers so the color comes back.
- Joint sand washout in commercial parking areas. Wind-driven rain along Junipero Serra Boulevard scours polymeric sand out of paver joints faster than anywhere inland. Once the sand goes, pavers start shifting. We re-sand with high-performance polymeric compounds rated for wet coastal exposure and re-compact the joints properly.
- Base settlement and paver heaving. Many older dealership and cemetery sites in Colma were built on undocumented fill. When that fill shifts or drainage fails, pavers sink, crack, or lift. We excavate to competent soil, install geotextile separators, and compact aggregate in lifts so the repair holds.
- Corrosion of metal edge restraints. The salty coastal air here eats standard aluminum and galvanized steel restraints. Loose pavers around walkways and driveways usually trace back to a rusted edge. We replace with corrosion-resistant materials and re-secure the perimeter properly.
- Color and dimensional mismatch from previous patches. When someone used a non-Unilock paver to patch a Unilock surface, the result never blends. We source Unilock’s OEM pavers for repairs so the texture, thickness, and color actually match the original install.
Unilock Service in Colma: What Local Conditions Mean for Your Equipment
Here’s what most paver guides miss about Colma: the town has roughly 1,500 living residents and more than 17 cemeteries. That means almost all paver and hardscape work here is commercial or institutional, not residential. We’re talking dealership showroom pads, cemetery walkways, mausoleum approaches, and tenant improvements on properties owned by cemetery districts as often as private owners. On Junipero Serra Boulevard and along El Camino Real, permits and plan reviews go through a small city building department intensely focused on the BART corridor and commercial frontage. For you, that means any paver project on a commercial or institutional property in Colma faces detailed review, especially around drainage and accessibility requirements. We’ve built enough of these projects to know what the reviewers look for before we submit. A residential paver patio in Daly City is a different permitting conversation than a Colma dealership entrance, and we plan accordingly. See our Colma service area page for more on how we work in town.
Unilock Models & Products We Service in Colma
We work with the Unilock lines most commonly specified for commercial and institutional hardscapes. Brussels Block remains the dominant paver for dealership lots and cemetery drives because it carries heavy loads without chipping. Beacon Hill flagstone-style pavers show up often on entries and elevated walkways. Eco-Optiloc, designed for permeable installations, fits projects where the city requires stormwater infiltration rather than sheet flow into drains. Opticurb gives us clean, radius-cut edges for islands and planters. When we repair any of these, we use Unilock OEM pavers for the surface course so color and dimension match. Below the pavers, we source quality aftermarket aggregate and geotextiles where they outperform, because performance under Colma’s damp conditions matters more than brand loyalty below grade.

FAQs – Unilock Construction in Colma
Yes, in some cases. If the existing slab is structurally sound, level, and drains properly, we can overlay Unilock pavers on a thin bedding layer. But Colma’s damp conditions mean any trapped moisture beneath pavers will cause problems later, so we only overlay when the slab’s drainage is verified and approved. Call (833) 382-8544 and we’ll tell you honestly whether overlay or full removal makes sense for your site.
Brussels Block, without question. It’s rated for heavy commercial traffic, resists chipping under vehicle loads, and holds up to the constant braking and turning forces dealership lots create. We’ve installed and repaired enough of them along Junipero Serra to know how they perform under daily commercial use. Call (833) 382-8544 for a site assessment.
Colma’s fog keeps pavers damp for long stretches, which accelerates efflorescence, algae growth on shaded surfaces, and joint sand degradation. You’ll need periodic re-sanding and occasional cleaning with products formulated for coastal exposure. Expect more frequent maintenance here than a paver owner in, say, Concord or Fremont would face.
For commercial and institutional properties along the BART corridor or El Camino/Junipero Serra frontage, likely yes. Colma’s building department reviews hardscape projects on those corridors closely, particularly for drainage and accessibility compliance. Residential patios in Colma are rare given the town’s housing stock, but if you have one, we’ll confirm permit requirements before starting. Call (833) 382-8544 and we’ll handle the paperwork.
Almost always, the pavement failed below the pavers, not the pavers themselves. Poor base compaction, undocumented fill, missing geotextile, bad drainage, or corroded edge restraints are the culprits. The fog accelerates surface issues like efflorescence, but structural failure is almost always a base problem. Call (833) 382-8544 for a free inspection and we’ll show you exactly what’s failing.

We recently replaced a failing paver driveway at a car dealership on Junipero Serra Boulevard, where the original Unilock Brussels Block had settled from poor base compaction and water intrusion off a nearby slope. Our crew pulled the old pavers, re-excavated the base, installed a geotextile separator and compacted aggregate, then reinstalled the pavers with new edge restraints and polymeric joint sand. The surface passed city inspection without delay and has held level under daily commercial traffic since. One call, done right, that’s the only way we know how to run a job.
