Unilock Construction in Interlaken, CA | San Bruno Construction
We provide independent Unilock paver installation and repair across Interlaken, CA – driveways, patios, walkways, and edge restoration. The thing that makes our Unilock work here different is simple: we install for the damp Pajaro Valley ground and the County of Santa Cruz permitting process, not against them. Call (866) 472-1908 for a free estimate on any Unilock hardscape project in the 95019 ZIP code.
Why Interlaken Residents Choose Us for Unilock Service
We’ve set Unilock pavers through several foggy Pajaro Valley winters and wet springs, so we know what this ground does to a base when it stays saturated for months. That experience matters more than a showroom full of samples. We’re an independent Unilock contractor, not affiliated with or authorized by Unilock, and we specify the brand on its own merits. Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and think through load paths before a single tool comes out of the truck. Over two-plus decades he’s run residential projects across San Mateo and Santa Cruz counties, and that same discipline drives how we approach every paver field in Interlaken – base first, drainage second, pavers third. For broader construction needs, we also work as an Interlaken General Contractor.
Our Unilock sales & service work covers the full scope: new paver driveways and patios, tear-outs of failing asphalt or concrete, edge restraint repair, joint re-sanding, and drainage correction. One contractor, every phase – from excavation to final polymeric sand set. We coordinate the trades so you don’t have to, and we quote with written line-item pricing before any work begins.

Common Unilock Construction Problems We Solve in Interlaken
- Polymeric joint sand washing out. Interlaken’s damp, foggy winters keep paver joints wet for weeks. When the sand never fully cures or drains poorly, joints open up and weeds push through by spring. We re-sand in a dry window and grade runoff so the joints actually set.
- White efflorescence on Brussels Block and Beacon Hill faces. A saturated base during the wet season pushes mineral salts up through the paver surface, leaving a chalky white bloom. We correct the base drainage and clean the face, not just re-seal over the problem.
- Edge restraint creep and paver spread at driveway aprons. Many older Pajaro Valley lots were graded with a shallow base that was never compacted to depth. Vehicle weight at the apron pushes the field outward and the edge restraint shifts. We re-excavate, re-set restraints, and compact properly.
- Moss and algae film on shaded Copthorne and Bristol Valley fields. Coastal fog means some Interlaken yards never fully dry under tree cover. Moss takes hold in the joints and on the paver surface. We address the drainage causing the constant moisture, then restore the field.
- Heaved or sunken sections from poor base drainage. On ground this damp, a base with trapped water will shift within two or three seasons. We dig to stable, well-draining aggregate, compact in lifts, and re-lay the same pavers where they’re still sound.
Unilock Service in Interlaken: What Local Conditions Mean for Your Equipment
Interlaken is unincorporated Santa Cruz County, so a paver driveway or patio here is permitted and inspected through the County of Santa Cruz rather than a city building office. That’s a real difference from working in Watsonville or Capitola, and it changes the schedule before any pavers are ordered. Because many Pajaro Valley parcels are rural or agricultural-tied, grading and drainage scope often gets reviewed alongside the hardscape. A paver patio that would sail through a city permit counter can get flagged for runoff direction or pad elevation in county review. Down the street in Interlaken service area neighborhoods, that’s just the rhythm of doing work here. We pull the county permits, coordinate the inspection scheduling, and build the drainage plan into the quote from day one.
On an older single-family lot off a rural Interlaken lane, we tore out a heaved asphalt apron and set a new Unilock Brussels Block driveway, excavating deeper than the original base to reach stable, well-draining aggregate. We also provide Unilock service in Freedom for similar coastal conditions. The winter fog had been keeping the old base saturated, so we graded runoff away from the house and re-set edge restraints before re-sanding the joints with polymeric sand in a dry window. The County of Santa Cruz signed off on the drainage and grading scope, and the driveway has held flat through two wet seasons.
Unilock Models & Products We Service in Interlaken
We install and repair the full range of Unilock paver lines that hold up in coastal climates: Brussels Block, Beacon Hill, Bristol Valley, and Copthorne. Each has different strengths on damp ground, and we match the product to the site, not the other way around. We use genuine Unilock pavers and matching edge restraints, and we specify quality open-graded base aggregate rather than cheap fill – because on Interlaken’s damp ground the base is what fails first. When a field is sound but joints and restraints are tired, we re-sand, re-set, and re-edge before recommending a full tear-out. Repair before replace, unless the base is already gone.

FAQs – Unilock Construction in Interlaken
Yes, in most cases. Interlaken is unincorporated, so hardscape projects go through the County of Santa Cruz rather than a city building office, and grading or drainage scope is often reviewed alongside the paver work. We pull the permits and coordinate the inspections as part of the job. Call (866) 472-1908 if you’re unsure whether your project falls under a county permit trigger.
On Interlaken’s damp ground, joint sand washes out when the base doesn’t drain and the sand never fully cures between fog cycles. Fix the drainage and grade first, then re-sand in a dry window, and the joints will hold. We diagnose the base condition before re-sanding so you’re not repeating the same repair every spring. Our Amesti Unilock service follows the same diagnostic approach on similarly damp ground.
Efflorescence happens when water moves through a saturated base and carries mineral salts up to the paver face, where they dry as a white bloom. It’s common in Interlaken because of the wet winters and heavy soils. The fix is drainage correction at the base level, not just surface sealing.
Yes, and that’s most of the work we do in Interlaken. Older rural lots often need grading corrections before any pavers go down, and the County of Santa Cruz typically reviews grading and drainage alongside the hardscape permit. We handle the full scope: grading, drainage, base, pavers, county inspections.
No. We’re an independent Unilock contractor, not affiliated with or authorized by the manufacturer. We specify and install Unilock pavers because they hold up well on coastal ground when the base and drainage are done right, and we use genuine Unilock products for every installation.
