Unilock Construction in San Martin, CA | Gold Star Contractors
We’re Gold Star Contractors, an independent Unilock construction service provider working throughout San Martin’s 95046 zip code. What sets our Unilock work here apart is simple: we understand that driving pavers and building segmental walls in unincorporated Santa Clara County means dealing with clay soils, county permitting, and septic setbacks that don’t exist in neighboring incorporated cities. Call (833) 382-8544 to talk with Noel Carranza about your project, whether it’s a paver driveway, patio, or a home addition that ties into existing hardscape.
We’ve installed and repaired Unilock Brussels Block, U-Cara, Beacon Hill, and Richcliff systems across the southern Santa Clara Valley for over a decade. We’re not an authorized Unilock dealer. We’re specialists who know the product lines deeply because we’ve seen how they perform on rural San Martin lots, where the ground doesn’t always cooperate and the county has its own way of doing things. Our Unilock sales & service experience means we specify components correctly the first time.
Why San Martin Residents Choose Us for Unilock Service
Most contractors working in San Martin treat paver installation like it’s the same job they’d do in Gilroy or Morgan Hill. It isn’t. The clay-heavy soils here shift under summer heat and swell during winter rains. A paver driveway laid without proper base work will look fine for a season or two, then start creeping and rutting. We’ve pulled up enough failed installations off Llagas Road and Foothill Avenue to know exactly what happens when corners get cut on rural lots.
Noel Carranza, our owner, grew up watching older tract homes get renovated block by block in Anaheim’s Platinum Triangle. He studied construction technology at Fullerton College, then spent years doing everything from concrete work to finish carpentry before building Gold Star Contractors. That background matters when your Unilock project involves grading questions, drainage swales, and county inspectors. We use Unilock OEM components and compatible base materials, never knockoff pavers or generic wall blocks, because the brand’s dimensional tolerances matter for long-term stability.

Common Unilock Construction Problems We Solve in San Martin
- Paver migration and edge failure on clay lots. San Martin’s expansive clay soil pushes laterally under summer heat. When a base was compacted without geotextile fabric, pavers creep toward the edges and the perimeter fails. We excavate properly, install the separator, and rebuild the base so the interlock holds.
- Efflorescence and surface staining on Brussels Block. Irrigation runoff from orchards and agricultural dust react with cementitious joint sand, leaving white, chalky stains on pavers. We correct drainage around the paved area and replace affected joint sand with polymeric material that resists the reaction.
- U-Cara wall settlement on sloped lots. San Martin properties often have grade changes. U-Cara walls without engineered geogrid reinforcement bulge and shift, especially where winter swale drainage isn’t moving water away from the wall base. We rebuild with proper geogrid and drainage.
- Cracking in segmental retaining wall blocks. Poorly drained soils and high winter water tables put freeze-thaw stress on wall units. The cracking usually starts at the base course. We repair or replace damaged units and correct the drainage behind the wall so it doesn’t happen again.
- Rutting on paver driveways with inadequate base depth. San Martin’s rural lots often see heavier vehicle traffic, tractors, trailers. A base too thin for the load ruts within a couple of wet winters. We re-excavate to proper depth and lay the pavers over a base that can actually carry rural traffic.
Unilock Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s the thing most people don’t realize until the county gets involved: San Martin is unincorporated, so a paver driveway or large patio project usually triggers Santa Clara County grading permits and drainage plans. That’s not the case for Unilock in Corralitos, Morgan Hill, or Gilroy, where city building departments handle it. If your project sits anywhere near a leach field, which is common on the acre-plus well-and-septic lots that define San Martin’s housing stock, county environmental health will require septic clearance before any excavation starts. A simple paver patio can become a permitting conversation about well setbacks and agricultural land grading questions. We’ve handled enough of these to know which forms to pull, what the inspectors want to see, and how to sequence the work so you’re not waiting on a drainage plan while your yard sits torn open. One call, done right. That’s the only way I know how to run a job.
Unilock Models & Products We Service in San Martin
We work regularly with four Unilock product lines: Brussels Block, U-Cara, Beacon Hill, and Richcliff. Each has different installation requirements. Brussels Block, with its tumbled finish and irregular edges, needs careful base work on clay soil. Richcliff’s larger-format look requires precise grading given its dimensional tolerance. U-Cara wall units demand geogrid reinforcement on any slope over a modest grade. Beacon Hill flagstone-pattern pavers need edge restraints specified for rural lots with organic soil movement. We match OEM materials for repairs, including color-matched replacement units where the product line still runs. For discontinued products, San Martin service area clients get straight advice on compatible alternatives rather than a mismatched patch job.

FAQs – Unilock Construction in San Martin
Yes, in most cases. Because San Martin is unincorporated Santa Clara County, paver driveway projects that involve grading, drainage changes, or work near a septic leach field require county permits and possibly environmental health clearance. We handle the paperwork and sequencing so you don’t have to navigate the county alone. Call (833) 382-8544 and we’ll tell you what your specific project will require.
Clay expands and contracts with moisture, which is why we excavate deeper than typical specs, install geotextile fabric as a separator, and use Class II base material compacted in lifts. Skipping any of those steps on San Martin clay means paver movement within one or two wet winters. We build bases that hold.
It depends on the concrete’s condition. If the slab is stable and not cracked from clay movement, an overlay install can work. But on most San Martin lots, existing concrete has shifted enough that overlaying pavers would just transfer the problem upward. We’ll assess the slab and tell you honestly whether an overlay or full re-excavation is the right call. The estimate is free, call (833) 382-8544.
For walls near leach fields, we recommend U-Cara with full geogrid reinforcement and proper drainage behind the wall. The key is keeping water moving away from both the wall base and the leach field. County environmental health will likely require clearance and setback verification before any wall construction starts. We coordinate that process as part of the project.
Brussels Block gives you a traditional, tumbled look that handles organic traffic well. Richcliff offers larger, more contemporary pavers with tighter joints. For San Martin’s clay soil, both need the same base prep, the difference is mostly aesthetic. We’ll bring samples to your property so you can see both against your existing hardscape and in your light before deciding. Call (833) 382-8544 to schedule a free estimate and sample review.

We replaced a failing Brussels Block driveway off Llagas Road that had been laid over raw clay. Two winters had shifted and rutted the pavers. We excavated to ten inches, installed geotextile and Class II base, re-compacted, and re-laid the same Brussels Block with Unilock edge restraints, tying drainage into the existing swale. The homeowner now has a stable, county-compliant driveway that handles summer heat and winter runoff. That’s the standard we bring to every San Martin project.
