Unilock Construction in Interlaken, CA | Framework Contractors
We install and repair Unilock paver systems across Interlaken, CA, including patios, driveways, and walkways on the unincorporated county parcels that make up this small Pajaro Valley hamlet, and we also offer Interlaken General Contractor services. The one thing that makes our Unilock work here different: every paver project that changes drainage or impervious surface falls under Santa Cruz County’s grading and drainage review, not a city building counter, and we handle that whole process for you. Call (844) 681-3590 for a free estimate on any Unilock paver project in Interlaken.
Why Interlaken Residents Choose Us for Unilock Service
We’ve installed Unilock pavers across the Pajaro Valley’s unincorporated parcels for years, from small bungalow patios to agricultural outbuilding aprons. We know how these systems behave under Interlaken’s wet winters, clay-heavy soils, and seasonal groundwater. We’re an independent contractor, not affiliated with Unilock, and we bring hands-on experience with Unilock’s full line of permeable and standard pavers. Noel Carbajal, our owner, has spent nearly three decades building and remodeling across central California. He grew up patching stucco and reroofing porches with his uncle before he could drive, and he’s carried that same get-it-done-right approach into every paver job we take on. We work with Unilock pavers because they hold up. We work in Interlaken because we understand what the county requires and what the ground actually does.

Common Unilock Construction Problems We Solve in Interlaken
Interlaken’s specific conditions create predictable Unilock paver failures. Here’s what we see most often:
- Paver settling and heaving: Interlaken’s clay-heavy soils expand and contract with winter rain. When the base wasn’t compacted deeply enough, or when seasonal groundwater saturates the sub-base, pavers sink and shift. We excavate to stable soil and rebuild the base properly, which usually means a geotextile separator and compacted aggregate, not just adding more sand.
- Edge restraint failure: Root intrusion from the oak trees that line many Interlaken properties pushes against paver edges over time. The plastic or aluminum restraint lifts, pavers drift outward, and the whole edge looks ragged. We reset the edges with proper spikes and, where roots are aggressive, add a concrete haunch to keep things where they belong.
- Efflorescence and salt staining: Winter rain plus agricultural runoff leaves white mineral deposits on Unilock surface, especially on Brussels Block in shaded areas. This isn’t a structural issue, but it looks bad. We clean it with the right efflorescence remover and can apply a quality sealer to slow future buildup.
- Color fading and surface wear: Cambridge Cobble sees real UV exposure and dust abrasion in windy, ag-adjacent yards throughout Interlaken. Older installations lose their color depth. We assess whether a deep clean and seal restores the look or whether the pavers need replacement in the worst sections.
- Base failure on old driveways: Many Interlaken homes still have the original mid-century asphalt or concrete driveways. When those are replaced with pavers, the old base often isn’t adequate for Unilock’s load requirements. We saw this firsthand on a ranch-style home off Larkin Valley Road, where years of winter runoff had settled the original base. We excavated to stable soil, installed a geotextile separator and compacted aggregate, then laid Brussels Block pavers with a slight crown to shed water toward a county-approved drainage swale. That driveway now handles seasonal runoff without shifting.
Unilock Service in Interlaken: What Local Conditions Mean for Your Equipment
Here’s what most out-of-town contractors miss about Interlaken: because the hamlet is unincorporated, any paver patio or driveway project that changes drainage or impervious surface can trigger Santa Cruz County grading and drainage review, not just a building permit. The county often requires engineered drainage plans for parcels near agricultural zones. That’s a step that wouldn’t apply in Watsonville or Capitola, which have their own building departments and different thresholds, though we do offer Unilock repair in Watsonville as well. On top of that, many Interlaken parcels sit on well and septic systems rather than municipal water and sewer. Any addition, major remodel, or paver project that changes surface flow must account for the septic leach field’s location and setback requirements. We’ve done enough jobs here to know which county reviewers look for what, and we build that into the estimate from day one so you don’t get a surprise stop-work order after we’ve already opened the ground.
Unilock Models & Products We Service in Interlaken
We work with the Unilock product lines that show up most often on Interlaken properties: Brussels Block, Cambridge Cobble, and Beacon Hill, and we also provide Unilock repair in Corralitos. We also service Techo-Bloc installations, Unilock’s sister brand, since many homeowners mix the two. For repairs, we source Unilock OEM pavers and proprietary edge restraints to maintain color and dimensional match. When OEM isn’t practical for base materials, we use quality aftermarket polymeric sand and aggregate that meet or exceed Unilock’s installation specs. For older installations, we assess whether targeted repair or a partial re-lay with new base makes more sense than patching failing sections. Often, re-laying a section with a properly compacted base is more cost-effective than repeatedly filling sunken spots.

FAQs – Unilock Construction in Interlaken
It depends on the project’s impact on drainage and impervious surface. A small patio that doesn’t change runoff patterns may not trigger review, but a paver driveway or anything that redirects water toward a property line or agricultural edge often does. The county’s grading and drainage review is separate from a building permit. We’ll tell you exactly what applies to your specific parcel before any work starts. Call (844) 681-3590 for a site walk and we’ll map out the county’s requirements.
Winter rain saturates Interlaken’s clay soils, which can cause base settlement and heaving if the base wasn’t built deep enough. The runoff also carries minerals that contribute to efflorescence. We build bases to handle the wet season: geotextile fabric, deeper aggregate, and drainage paths that move water away from the paver system.
Yes, in some cases. If the concrete slab is structurally sound and doesn’t crack from freeze-thaw (which is less of a concern in Interlaken’s mild climate), we can lay pavers over it with a setting bed and edge restraints. But if the slab has major cracking or drainage problems, we recommend removing it and building a proper base. We’ll tell you which route makes sense for your specific driveway or patio.
Brussels Block is our usual recommendation for Interlaken driveways. It handles the load, resists the surface wear that comes from dusty, ag-adjacent yards, and its color depth holds up better than lighter pavers under direct sun. For steep approaches or areas with heavy runoff, we may recommend a permeable paver option. Call (844) 681-3590 and we’ll walk your driveway and give you a straight answer.
We clean it with a commercial efflorescence remover formulated for concrete pavers, then rinse thoroughly. For properties near agricultural fields where runoff is constant, we apply a quality sealer to slow the mineral buildup. This is a cosmetic fix, not structural, and it’s usually a one-day job for us.
