Unilock Construction in Pasatiempo, CA | Silver Line Contractors
We install and repair Unilock pavers and retaining walls across Pasatiempo as a General Contractor, not a manufacturer rep. The thing that separates our Unilock work here is the way we read hillside drainage and county permitting before the first base course ever goes down. If you’re planning a paver driveway, patio, or retaining wall in Pasatiempo, call (833) 400-1314 for a free estimate.
Why Pasatiempo Residents Choose Us for Unilock Service
Noel Carvalho has spent years placing Unilock pavers and Uni-Stone II walls on wooded hillside lots throughout the Santa Cruz Mountains, including Mount Hermon Unilock service areas. He grew up in Gilroy’s south end, studied construction technology at Gavilan College, and spent his twenties and thirties working every phase of residential builds across Santa Clara County before starting Silver Line Contractors. That background matters here, because Pasatiempo lots don’t forgive rushed base prep or lazy drainage work. We’re not affiliated with Unilock, endorsed by them, or acting as their warranty agent. Our credibility comes from completed installs that hold through wet winters and fog-belt moisture. We stock genuine Unilock units, Unilock-matched edge restraints, and polymeric joint sand so repairs and rebuilds keep their color match and interlock.
We also carry the full hardscape scope that a Unilock project often needs, including the Unilock sales & service side, paver patios, driveways, and concrete work. When you’re in Pasatiempo, we’re the crew that handles the whole thing under one contract.

Common Unilock Construction Problems We Solve in Pasatiempo
Every paver and wall failure comes down to water, compaction, or restraint. In Pasatiempo, all three get tested harder than most places in the county.
- Paver heave and settlement over clay hillside soil. Pasatiempo’s wet winters and fog-belt moisture push saturated clay to expand and shift. When a base was compacted over that clay without proper drainage, you’ll see pavers heave within a season or two. We rebuild in lifts, add drainage, and re-compact before resetting units.
- Efflorescence and salt bloom on tumbled Unilock pavers. White chalky residue every winter usually means water is sitting under the surface because the slope drain or French drain outlet was never daylighted down the hill. We trace the water path, cut the outlet where it actually drains, and the bloom stops returning.
- Uni-Stone II retaining wall bulging and block-face cracking. When the geogrid and gravel backfill are undersized for a saturated hillside load, the wall starts leaning. On Pasatiempo slopes, a saturated wall is a structural problem, not a cosmetic one. We assess the grid, the backfill, and the drainage, then tell you straight: repair or rebuild.
- Joint sand washout and edge restraint failure on driveways. Heavy storm runoff pushes poly sand out of joints and lets pavers migrate toward the border, where they chip and loosen. We re-level, re-sand, and rebuild edge restraints so the field stays locked.
- Settled patios caused by trapped runoff against foundations. On wooded lots where the original slab trapped winter runoff against a garage or walkway, we cut a new drainage swale and rebuild the base so the patio sheds moisture instead of puddling it.
Unilock Service in Pasatiempo: What Local Conditions Mean for Your Equipment
Pasatiempo is an unincorporated Santa Cruz County island ringed by the City of Santa Cruz, and that jurisdictional quirk changes how paver and wall projects get permitted here. A paver driveway or patio in Pasatiempo is reviewed under county grading, drainage, and wildland-urban-interface fire-safe rules, not city rules. And because many wooded lots sit on sandhill habitat, a biological review can affect how we set grades and disturb soil. That means a paver driveway that would sail through a City of Santa Cruz permit might need a drainage plan, a fire-safe materials check, and a habitat note in Pasatiempo. We handle all of that. On a wooded lot off Pasatiempo Drive near the golf club, our crew replaced a settled concrete drive with a Unilock Brussels Block paver driveway, cutting a new drainage swale and daylighting the outlet downslope because the original slab had trapped winter runoff — similar to Twin Lakes Unilock service projects we handle.f against the garage. We rebuilt the base in lifts over the clay, set Unilock edge restraints, and finished with polymeric joint sand. That driveway sheds fog-belt moisture instead of puddling it. Good construction doesn’t need a sales pitch, the work explains itself.
Unilock Models & Products We Service in Pasatiempo
We work with the Unilock lines that hold up on hillsides and in fog-belt moisture. Brussels Block is our go-to tumbled paver for driveways that need to shed runoff without looking slick. Beacon Hill Flagstone gives patios a flagstone-look surface with dimensional strength, and its tumbled finish hides minor surface wear better than smooth pavers. Elegance large-format slabs suit level patios and walkways. For retaining, we work with Uni-Stone II, and we stock genuine Unilock edge restraints and poly sand locally for faster Unilock in Bonny Doon and Pasatiempo turnaround. Where a field is largely sound, we re-level, re-sand, and rebuild drainage rather than sell a full tear-out. When base failure or wall movement is structural, we say so plainly. We’re an independent contractor using genuine Unilock products, not an authorized dealer.

FAQs – Unilock Construction in Pasatiempo
Yes, if the base, drainage, and edge restraints are built for the slope. We compact in lifts over the native clay, cut a drainage swale that actually daylights downslope, and set Unilock-matched edge restraints so the field can’t migrate. Pasatiempo slopes tested by wet winters need exactly that. Call (833) 400-1314 for a slope-specific estimate.
Yes. Pasatiempo is unincorporated county land, so your paver driveway or patio is reviewed under county grading, drainage, and fire-safe rules, not city rules. Some wooded lots also trigger a sandhill habitat review. We pull the permits and handle the paperwork. Call (833) 400-1314 if you want us to check your specific lot.
That white bloom means water is sitting under the paver surface and wicking up through the concrete. In Pasatiempo, the cause is usually a slope drain or French drain outlet that was never daylighted down the hill. We locate the trapped water path, fix the outlet, and the efflorescence stops returning. Call (833) 400-1314 to have us trace it.
It depends on whether the geogrid and gravel backfill were sized for a saturated hillside load. If the wall is bulging, the grid or backfill is undersized, and a rebuild is usually the only durable fix. If it’s just settling at the cap, we can often re-level and rebuild the top courses. Call (833) 400-1314 for an assessment, and we’ll tell you which one you’re looking at.
