Unilock Construction in Interlaken, CA
We install, repair, and re-level Unilock pavers, patio systems, and retaining walls across Interlaken – and we do it as an Interlaken General Contractor, not a manufacturer showroom. The thing that changes how Unilock work plays out here is the permitting: Interlaken sits in unincorporated Santa Cruz County, so hardscape projects run through county planning, not Watsonville’s building department. That matters more than most homeowners realize, especially on ag-adjacent parcels. Call us at (877) 373-9230 for a free estimate on your Unilock project.
Why Interlaken Residents Choose Us for Unilock Service
We’ve spent years working Unilock systems across the Pajaro Valley, from Copthorne patios to Brussels Block driveways, and we’ve learned what these products do when coastal fog and winter rain sit on them month after month. Noel Cardenas, our owner, grew up in a construction family and has been running crews on hardscape and structural work long enough to know that a paver is only as good as the base beneath it. That’s why we spec our own aggregate, geotextile, and polymeric joint sand rather than whatever’s cheapest at the supply yard. We’re not affiliated with Unilock or authorized by them – we just work with their product because it holds up in Interlaken‘s damp, clay-heavy ground when the base, drainage, and edge restraint are built correctly. For broader Unilock sales & service context, that independence is exactly what lets us tell you when a repair will work and when a full rebuild is the honest answer.

Common Unilock Construction Problems We Solve in Interlaken
Interlaken’s conditions create specific failure patterns. These are the ones we see most:
- Efflorescence and salt bloom on Brussels Block and Copthorne pavers. Foggy mornings off Monterey Bay keep paver surfaces damp well into the afternoon, so minerals wick up through the concrete and leave a white haze that never fully dries out. We clean it properly and adjust drainage so it doesn’t come right back.
- Settling and lippage on driveways and patios. Pajaro Valley clay expands and contracts through wet winters and dry summers. When the original base was laid thin – common on older Interlaken properties – pavers start to dip and lift at the edges, creating trip hazards and ponding.
- Edge restraint failure and paver creep. Many rural-residential and farmworker-era homes in Interlaken never had a proper concrete curb or soldier course. Without edge restraint, the whole field slowly migrates outward, especially on sloped lots.
- Moss and algae in joint sand and along Estate Wall caps. Shaded, north-facing patios and outbuildings stay wet long after the rain stops. Organic growth pushes apart joints and lifts caps, and standard joint sand just feeds the problem.
- Heaved patio bases from poor drainage. When water has nowhere to go, it saturates the base material, freezes in cold snaps, and thaws – heaving pavers upward and cracking the surface pattern.
Unilock Service in Interlaken: What Local Conditions Mean for Your Project
Here’s the thing that most generic Unilock pages won’t tell you about Interlaken. This community is unincorporated, so every paver driveway, patio, and retaining wall project goes through Santa Cruz County Planning and Building Services – not a city hall. And because much of the surrounding land is active Pajaro Valley agriculture, setback and ag-exemption rules often come up right alongside the hardscape plan. On parcels bordering farm fields, we’ve had to adjust driveway layouts and patio footprints to respect county setback lines that wouldn’t apply inside Watsonville city limits. A paver driveway that’s perfectly fine five feet from a property line in Corralitos can trigger a county review out here. That changes how we lay out your project from day one, and it’s why we pull permits when they’re required and walk the county requirements with you before any pavers hit the ground.
Unilock Models & Products We Service in Interlaken
We work with the Unilock lines most common on Interlaken properties: Brussels Block for that classic tumbled look on patios and walkways, Beacon Hill for driveways that need a more uniform finish, Copthorne for a straight-edged modern aesthetic, and Estate Wall for retaining walls, steps, and raised planters on sloped rural lots. We use genuine Unilock pavers, wall units, caps, and matching edge restraints so any repair blends with what’s already installed. For base and drainage, we bring in quality aggregate, geotextile fabric, and polymeric joint sand – not the cheap fill that fails in two seasons. If a field of pavers is sound but the base has settled, we re-level and re-sand it. We only recommend replacement when the base is fully compromised or the units themselves are spalled and cracked.

FAQs – Unilock Construction in Interlaken
That white haze is efflorescence – minerals wicking up through the paver from moisture that never fully evaporates because of Interlaken‘s foggy mornings. The moss is a separate issue: constant shade and damp joints. We treat both by cleaning the surface, fixing drainage so water moves away from the field, and re-sanding with polymeric sand that resists organic growth. Call (877) 373-9230 for an evaluation.
Yes. Interlaken is unincorporated Santa Cruz County, so hardscape permits come from county planning and building services, not Watsonville’s city hall. On parcels near active agricultural land, setback and ag-exemption rules often apply. We handle that paperwork and flag any county requirements before we start.
In most cases, yes. If the pavers themselves are intact and the problem is a settled base, we lift the field, rebuild the base with proper aggregate depth and geotextile, re-lay the existing units, and re-sand the joints. Replacement only makes sense when the base is destroyed or the pavers are cracked and spalled. We’ll tell you which one you’re looking at.
You build the base correctly the first time – which means excavating to the right depth, compacting in lifts, laying geotextile fabric to separate the aggregate from the clay, and installing solid edge restraint. On Interlaken clay that saturates with winter rain, skimping on any one of those steps is a future re-level job. We don’t skip them.
We do. Estate Wall is what we spec most often on sloped Interlaken parcels because it handles grade changes cleanly and works well for raised planters, steps, and low retaining walls. We account for drainage behind the wall and proper footing depth so it doesn’t lean after a wet winter. Call (877) 373-9230 for a free estimate.
