Unilock Construction in Mountain View, CA
We install, repair, and re-base Unilock paver systems across Mountain View, from flatland Eichler neighborhoods to the hillside custom homes in 94040 and 94041. What separates our Unilock work here is the base: Mountain View’s expansive clay subgrade demands a deeper, more heavily compacted foundation than most installers bother with, and we document it. Independent of Unilock corporate, we bring contractor-level scrutiny to every edge restraint, drainage plane, and paver rating so your driveway or patio stays flat through winter rains, not just through inspection. Call (877) 373-9230 for a free estimate on your Unilock project in Mountain View.

Why Mountain View Residents Choose Us for Unilock Service
Unilock pavers are a premium product, and they fail predictably when the base underneath them fails. Noel Cardenas, our owner, grew up learning construction the hard way, through Santiago Canyon College’s trades program and years running every phase of residential builds, and he’ll tell you the same thing we tell every home remodeling homeowner: “The material you pick today is the problem you solve – or the one you live with – ten years from now.” That’s why we spend more time below the paver than above it. We know the Brussels Block, Brussels Dimensional, Beacon Hill, and Onyx lines well enough to match existing work, identify depth and compaction problems before they spread, and repair settled surfaces without tearing out sound pavers. As an independent installer, we’re not tied to Unilock’s installation checklist. We’re tied to how clay soil in the flatlands actually behaves when it rains.

Common Unilock Construction Problems We Solve in Mountain View
- Paver settlement from expansive clay. Mountain View’s flatlands sit on clay that swells with winter rain and shrinks in summer. When the soil moves, a shallow base moves with it, and Unilock pavers sink or heave unevenly. We excavate to the proper depth, add a geotextile separator, and re-compact in lifts.
- Edge restraint failure where pavers meet concrete. Many 1950s and 60s ranch homes have original slab-on-grade carports and aging concrete driveways. Without aggressive edge restraint at that transition, Unilock pavers creep laterally and joints widen. We install OEM edge restraints rated for the load and pin them correctly.
- Staining and efflorescence on Brussels Block. Mountain View’s rainy season hits light-colored pavers hard. Poor initial drainage away from the foundation pushes water up through the joints, leaving white mineral deposits and staining. We regrade the base plane and use compatible joint sand to restore the original color reading.
- Fading and surface wear from missing geotextile. Older Unilock installs over clay without a separator allow subgrade fines to pump up through the joints. The surface dulls, the pavers shift, and the color fades unevenly. Lifting, separating, and re-laying fixes the movement without replacing the material.
- Drainage problems in Eichler-style flatland lots. Radiant slab homes with no attic or crawlspace often channel runoff toward the house. Unilock patios and driveways must pitch away correctly, or the water pools against the garage slab and starts undermining edges within a few seasons.
Unilock Service in Mountain View: What Local Conditions Mean for Your Pavers
Here’s the headline most contractors skip: Mountain View’s flatlands sit on expansive clay, not the sandy loam you find a few miles up the Peninsula. Clay swells when it absorbs winter rain and shrinks when summer pulls the moisture out. That movement transfers directly into your Unilock base if the base wasn’t engineered for it. In neighborhoods like Monta Loma and the streets off Middlefield Road, we typically excavate to eight inches, install a geotextile separator, and compact the aggregate in controlled lifts before a single Brussels Block or Beacon Hill paver goes down. The city’s design-review process often asks for documentation of exactly that detail, because Mountain View planning staff understand what expansive soil does to hardscape over time. We recently handled Unilock in Sunnyvale and re-based a settled Brussels Block driveway in the 94040 flats, where the original installer had compacted only four inches of base over raw clay. After lifting the pavers, we excavated to eight inches, added the separator, re-compacted in lifts, and reset the blocks with new edge restraint, restoring a flat, stable surface and proper drainage away from the garage slab. That’s not a premium upsell. It’s the minimum that works here.
Unilock Models & Products We Service in Mountain View
We install and service the full range of Unilock residential products, with Unilock repair in Loyola and the deepest experience in Brussels Block, Brussels Dimensional, Beacon Hill, and Onyx. When a repair calls for edge restraints or joint sand, we use Unilock OEM parts matched to the product line. For bases and geotextiles, we source high-quality aftermarket materials that meet or exceed Unilock spec, selected for the clay subgrade here, not whatever a supplier has on the shelf. When existing pavers are sound but shifted or sunken, we lift, re-base, and re-lay rather than replace, saving Mountain View owners thousands in material costs while restoring a surface that drains and locks together like the day it was installed. We also handle full Unilock driveway replacement and patio construction where the original installation wasn’t worth saving.

FAQs – Unilock Construction in Mountain View
Yes. Expansive clay in Mountain View’s flatlands requires a deeper base, typically eight inches or more with a geotextile separator, compared to shallower bases that hold up fine on sandy loam elsewhere on the Peninsula. We document this because the city’s design reviewers often ask for it. Call (877) 373-9230 for an exact base specification for your lot.
We can match Brussels Block closely in color, size, and finish, though UV exposure and years of wear mean new pavers won’t be indistinguishable from old ones. We’ll pull a sample from your existing installation and quote the match before we order. Call (877) 373-9230 to schedule a look.
Mountain View’s planning department reviews hardscape changes for drainage, lot coverage, and materials, especially on Eichler and ranch properties. We prepare submittal-ready drawings for base depth, edge restraint, and drainage pitch so your permit doesn’t stall. Call (877) 373-9230 if you’re wondering whether your scope even triggers review, because the answer isn’t always obvious.
The primary cause is expansive clay swelling and shrinking beneath an under-built base. Secondary causes are missing geotextile separators and inadequate edge restraint where pavers meet slab-on-grade concrete. We identify the specific cause before we touch a paver. Call (877) 373-9230 and we’ll explain what’s happening under your surface.
In most cases, yes. If the pavers themselves are intact, we lift them, correct the base, install a separator if needed, and re-lay the same material with fresh OEM joint sand. That typically costs a fraction of full replacement. Call (877) 373-9230 for a site assessment.
