Unilock Construction in Gilroy, CA | Milpitas Construction
Milpitas Construction provides independent Unilock paver installation and repair across Gilroy, including zip codes 95020 and 95021, and San Martin Unilock service. Ken Stafford and our crew have installed and repaired Brussels Block, Cambridge Cobble, and Beacon Hill pavers on driveways, patios, and retaining walls throughout South Santa Clara County. What makes our Unilock work different here is simple: we over-excavate and geogrid-reinforce every base because Gilroy’s expansive clay and the Hecker Pass wind corridor will expose a shortcut within two seasons. We’re not authorized by Unilock, but we know their systems better than most. Call (877) 752-4194 for a free estimate.
Why Gilroy Residents Choose Us for Unilock Service
We’ve been working with Unilock pavers long enough to know which failures are product issues and which are installation issues. In Gilroy, it’s almost always the latter. The housing stock here – 1980s and 1990s Mediterranean and Spanish-revival stucco tract homes with concrete flatwork that’s now cracking – means we’re frequently called to replace failing driveways, walkways, and backyard patios on lots where the original concrete was poured directly on shrink-swell clay. Homeowners want a surface that won’t crack like their old slab, and Unilock’s segmental paver system is the right answer. Ken grew up near the Milpitas BART corridor and has spent two decades in Bay Area construction, so he specs every Unilock base for seismic movement and clay expansion, not just manufacturer minimums. We quote repair-first when the base is sound. If it isn’t, we tell you why before we ever start digging.

Common Unilock Construction Problems We Solve in Gilroy
- Efflorescence and salt bloom on Brussels Block and Cambridge Cobble. Gilroy’s irrigation water runs hard and mineral-heavy, and the rapid dry-out between fog-cooled mornings and hot afternoons pulls those minerals to the paver surface as white deposits. It’s rarely a product defect. We clean it and often adjust the joint sand or drainage to slow the cycle.
- Edge spalling and joint sand loss on driveways. The wind corridor through Hecker Pass drives grit across exposed paver fields, and seismic micro-movement opens joints in the unit layer. We see this constantly on west-facing driveways in the newer subdivisions. Re-setting edge restraint and re-sanding with polymeric sand usually fixes it.
- Base settlement and paver rutting on sloped lots. Gilroy’s clay shrinks and swells with moisture. Where the original installer skipped a proper compacted aggregate base, driveways rut within two seasons. This is the single most common failure we repair in the northwest subdivision edges.
- Color fade and surface pitting on older Unilock pavers. Intense valley UV plus repeated dawn moisture cycles weathers the surface over a decade or more. Homeowners often think it’s a manufacturing defect. It’s wear. We match the field and replace only the damaged units when possible.
- Drainage failures around patios and walkways. Gilroy’s valley floor gets fog drip and occasional heavy winter rain. If the base wasn’t sloped correctly or edge drains weren’t set, water ponds and undermines the bedding layer. We re-slope and re-set rather than just patching the surface.
Unilock Service in Gilroy: What Local Conditions Mean for Your Equipment
Here’s the thing most paver contractors in San Jose or Morgan Hill Unilock service providers won’t tell you about Gilroy: a Unilock driveway that performs fine in their cities can rut and heave here within two seasons. The reason is the soil. Gilroy sits on expansive clay that shrinks in summer and swells in winter, and the valley’s position between the Santa Clara and San Benito ranges funnels wind through the Hecker Pass gap. That combination means the base under your pavers gets more movement than the manufacturer’s standard installation guide assumes. We over-excavate and install geogrid on every driveway and patio in Gilroy, especially on the sloped lots up toward the northwest subdivisions near Las Animas Avenue. Base depth matters more than paver brand in this town. If you skip the base work, you’ll be re-setting pavers before the next garlic festival.
Unilock Models & Products We Service in Gilroy
We install and repair the full Unilock line we encounter across Gilroy homes: Brussels Block, Cambridge Cobble, and Beacon Hill flagstone-style pavers, plus Unilock-compatible slab systems like Techo-Bloc Blu 60 for modern designs. When color and dimension must match an existing field, we order genuine Unilock pavers and matching Edge Restraint. For polymeric joint sand and base aggregate, we spec quality aftermarket materials where performance matters more than brand label. We keep common joint sands, edge restraints, and base materials stocked locally so Gilroy turnaround is measured in days, not weeks. We also handle full paver driveway installation, paver patio installation, and driveway replacement, including demolition and haul-off of the old concrete.

FAQs – Unilock Construction in Gilroy
Yes, if the base is built for clay. We over-excavate below the expansive soil layer, compact Class II aggregate in lifts, and lay geogrid reinforcement before the bedding course goes down. That’s what keeps pavers flat when the clay under them swells and shrinks. Call (877) 752-4194 and we’ll tell you exactly what your site needs.
It depends on where your property sits. Within Gilroy city limits, standard paver patios and driveway replacements usually don’t need a building permit, but anything beyond the city boundary can fall under Santa Clara County agricultural-preserve rules where grading and impervious-surface limits apply differently. We also handle Unilock repair in Aromas where county regulations may vary. We check the parcel status on every Gilroy job before we quote. Call (877) 752-4194 and we’ll pull the records.
Almost never. The white bloom you’re seeing is efflorescence, and in Gilroy it’s driven by hard irrigation water and rapid morning-to-afternoon dry-out cycles. It’s cosmetic and cleanable, though if it keeps returning, drainage or joint sand is usually the culprit. We’ll diagnose it and tell you if it’s worth fixing. Call (877) 752-4194 for an honest read.
Yes, we order genuine Unilock Brussels Block in the same color blend and finish to match your existing field. With older installations, slight shade variation is normal due to years of sun exposure, but we’ll bring physical samples to your Gilroy property and lay them against the existing pavers before ordering. Call (877) 752-4194 to set up a color match visit.
The Hecker Pass wind corridor picks up grit and pushes it across paver surfaces, which accelerates joint sand loss on exposed patios and driveways. We combat that by using polymeric sand with a stronger binder and making sure edge restraint is set firmly on all sides. On open, west-facing lots, we may also recommend a slightly deeper joint fill. Call (877) 752-4194 and we’ll factor wind exposure into your quote.
