Belgard Construction in Interlaken, CA | Silver Line Contractors
We’re Silver Line Contractors, an Interlaken General Contractor serving the area with Belgard paver, patio, driveway, and retaining wall construction. We’re not affiliated with Belgard or operating as an authorized dealer. What sets our Belgard work apart in Interlaken specifically is that we build every project around the county’s drainage and base-prep scrutiny, because in this clay-heavy, river-adjacent valley, the base is the project. If you’re planning a Belgard paver patio, driveway, or wall system in the 95019 area, call (833) 400-1314 for a free estimate.
Why Interlaken Residents Choose Us for Belgard Service
Noel Carvalho, our owner and general contractor, grew up watching his father patch and improve the family home in Gilroy’s south end. That was where he learned good work either holds or it doesn’t. He studied construction technology at Gavilan College, then spent the better part of two decades running residential and commercial builds across Santa Clara County before starting Silver Line Contractors. What that means for Interlaken homeowners is this: we’ve torn out enough failed hardscape to know exactly how Belgard products behave in Pajaro Valley soil, and we’ll tell you plainly when a base needs rebuilding instead of patching.
We also bring something most paving-only crews don’t. As Belgard sales & service specialists, we’re a full-scope general contractor. We can run a paver driveway, a retaining wall, and a home addition under one contract, one schedule, and one point of accountability. From the roof down to the driveway, as we like to say. In Interlaken service area terms, that matters because county review and drainage work often tie exterior hardscape to the rest of the property in ways a single-trade installer won’t address.

Common Belgard Construction Problems We Solve in Interlaken
Interlaken’s damp, fog-influenced climate and flat, clay-heavy terrain create a specific set of Belgard failure patterns we see repeatedly. Here’s what we fix most:
- Efflorescence bloom on Lafitt and Catalina pavers. Coastal fog and damp winter cycles leave north-facing patios perpetually moist, and the salts in concrete pavers migrate to the surface as white bloom. It’s cosmetic but persistent. We clean it properly and address the drainage that feeds it, so it doesn’t return every season.
- Base failure and rutting over native clay. We see this constantly in Interlaken. Pavers set directly on Pajaro Valley clay without a compacted aggregate base will shift, sink, and develop lippage after seasonal flooding. We strip the section, install proper base and drainage, and re-set the pavers.
- Segmental retaining wall movement on slopes near the river. Urbana Stone and Brighton wall courses bulge when backfill and drainage weren’t built for heavy rain. On sloped parcels near the Pajaro River corridor, this isn’t cosmetic. A bulging wall is a structural problem. We rebuild with proper geotextile, drainage aggregate, and pinned courses.
- Paver joint sand washout along driveways and walkways. Storm runoff follows the same paths every winter in Interlaken, and unsealed or poorly edged Belgard surfaces lose joint sand there first. Weeds follow. Settlement follows the weeds. We re-sand with quality polymeric sand and install pinned edge restraint before the problem compounds.
- Edge restraint loosening from seasonal storm runoff. When the edge lets go, the whole field starts migrating. On Belgard driveways near drainage swales, this shows up as a spreading edge course within two or three wet seasons. We address it at the source.
Belgard Service in Interlaken: What Local Conditions Mean for Your Project
Here’s the single most important thing to understand about Belgard work in Interlaken: most parcels here fall under Santa Cruz County jurisdiction, not a city building department, and many sit near the Pajaro River floodplain. That means paver and retaining-wall projects often need grading and drainage documented for county review before a single paver goes down. The base design, not the surface, is what the county scrutinizes. A generic paver installer who shows up, scrapes the topsoil, and starts laying pavers is setting you up for a failed inspection or a failed patio. We handle the grading plan, the drainage design, and the county paperwork as part of the scope. If your Interlaken property is near the floodplain, that’s not an inconvenience. It’s the entire ballgame.
On a parcel off the Pajaro River corridor in the 95019 area, we pulled up a Belgard Lafitt Rustic Slab patio that had heaved and rutted where it sat on bare native clay with no aggregate base — a pattern we also address with Belgard repair in Watsonville. Our crew stripped it back, cut in drainage to move the winter sheet flow away from the house, rebuilt the base with compacted aggregate, and re-set the salvaged Lafitt pavers with fresh polymeric sand and pinned edge restraint. The patio has since ridden out two wet seasons without the lippage the owner had been fighting.
Belgard Models & Products We Service in Interlaken
We install and repair Belgard Lafitt Rustic Slab pavers, Catalina Grana pavers, Urbana Stone wall block, and the Brighton retaining wall system, including Belgard service in Freedom. For color and dimensional match on repairs, we use genuine Belgard pavers and wall units. Where the spec allows, we pair them with quality aftermarket polymeric joint sand, edge restraints, and geotextile. If a Belgard surface is only showing efflorescence or localized joint loss, we clean and re-sand. If the base has failed from drainage or clay movement, we rebuild the section rather than patch over it, because patching over a dead base just burns the money twice.
Sub-services we emphasize on Interlaken Belgard work: paver patio installation, paver driveway installation, and complementary home additions where the hardscape ties into the structure, similar to our Belgard repair in Corralitos.

FAQs – Belgard Construction in Interlaken
Why do my Belgard pavers keep turning white near the coast in Interlaken?
That’s efflorescence, a salt bloom caused by moisture migrating through the pavers and evaporating at the surface. Interlaken’s fog and damp winter cycles feed it constantly, especially on north-facing patios that never fully dry out. Cleaning helps, but if the drainage under the pavers isn’t fixed, it’ll return. Good construction doesn’t need a sales pitch; the work explains itself. Call (833) 400-1314 and we’ll tell you if your base is the culprit.
Do Belgard paver projects in Interlaken need county approval instead of a city permit?
Yes, in most cases. Interlaken falls under Santa Cruz County jurisdiction, and paver or retaining-wall projects near the Pajaro River floodplain often require grading and drainage documentation submitted for county review. We handle that paperwork as part of our scope. Call (833) 400-1314 to talk through what your specific parcel needs.
Will a Belgard retaining wall hold up on wet Pajaro Valley clay slopes?
Only if the base, backfill, and drainage are built for it. Urbana Stone and Brighton systems are solid products, but clay soil that holds water will push a wall out if the drainage behind it isn’t right. In Interlaken, we build Belgard walls with drainage aggregate, geotextile, and proper setback specifically because the clay here doesn’t forgive shortcuts.
My Belgard driveway settled after the last rainy season. Repair or rebuild?
Depends on what’s underneath. If the base is intact and only the surface shifted, localized repair and re-sanding is enough. If the base failed, because it was set on clay without aggregate, rebuilding the section is the only fix that lasts. We’ll tell you which one you have. Call (833) 400-1314 for an honest assessment and a free estimate.
Can we add a Belgard patio or walkway as part of an addition on our Interlaken property?
Yes, and that’s exactly the kind of project we run as a single contract. We can build the addition and the Belgard hardscape together, with one schedule and one point of accountability. It means the drainage, grading, and county review all get handled once, not twice. Call (833) 400-1314 to talk about scope.
