Unilock Construction in San Jose, CA | Moreno Valley Builders
We build and repair Unilock paver systems across San Jose as an independent San Jose General Contractor, not a manufacturer affiliate. What separates our Unilock work here is that we treat every paver project as a base-and-drainage problem first, because San Jose’s pre-1950 bungalow lots hide decades of unrecorded concrete and bad fill that will wreck a new paver field if you skip the investigation. Call (877) 752-3154 for a free estimate on Unilock patio, driveway, or walkway work in San Jose.
Why San Jose Residents Choose Us for Unilock Service
Noel Trevino grew up in the Sunnymead Ranch area of Moreno Valley and has spent the better part of three decades building across the Inland Empire and the Bay Area. That background matters on Unilock jobs, because the failure we see most often in San Jose has nothing to do with the pavers themselves. It’s what’s underneath them. We carry genuine Unilock units and Unilock-compatible polymeric sand and edge restraint, and we refuse to substitute thin box-store pavers on a driveway where full-depth units are the only thing that holds up on valley clay. We manage the full scope, so a homeowner never gets bounced between a paver crew, a concrete guy, and a drainage sub. One contractor. Every phase.

Common Unilock Construction Problems We Solve in San Jose
- Efflorescence and joint-sand washout on clay-heavy valley-floor soil. San Jose’s expansive clay expands and contracts through the wet-dry cycle, and when a paver base was never over-excavated and drained, moisture wicks up through the joints and leaves behind that chalky white bloom. We fix it by re-establishing a clean, free-draining base and re-sanding with polymeric joint material that resists washout.
- Edge restraint failure and field spreading. In 95110 – 95113, we regularly find paver fields that were set against an old unpermitted concrete apron someone poured decades ago. That apron shifts or heaves, the edge restraint lets go, and the whole field starts to creep outward. We reset the field, install proper aluminum edge restraint, and tie the layout to what’s actually on record.
- Settlement and rocking over backfilled former additions or utility trenches. A lot of San Jose’s older bungalows had additions or trench work done without proper compaction. When Unilock pavers go over that uncompacted fill, you get low spots that hold water and rock underfoot. We over-excavate, re-compact in lifts, and build a base that won’t settle again.
- Moss, staining, and faded color on shaded north-facing patios and narrow side-yard walkways. San Jose’s Mediterranean wet season keeps joints damp for months on end, and the north side of a house rarely sees direct sun. Moss takes hold, joint sand washes out, and the paver color dulls. We deep-clean, re-sand, and where the shade is permanent, we talk with homeowners about paver choices and drainage details that hold up better in low light.
- Cracked or spalled units from tree roots and poor base prep. Mature street trees in San Jose’s older core are beautiful, but their roots will find a weak base in a few seasons. We replace only the damaged Unilock units and rebuild the base where the root intrusion happened, so the repair stays true instead of telegraphing through the field.
Unilock Service in San Jose: What Local Conditions Mean for Your Equipment
San Jose’s pre-1950 bungalow blocks in 95110 – 95113 routinely turn up unpermitted additions and slab-on-grade patios that were never on record. Before we set a Unilock base, we pull what as-builts exist and then compare them against what’s actually buried. The paver layout is often decided by someone else’s old pour, not by our design. On a narrow Craftsman lot off North 4th Street in the 95112 core near Unilock service in Alum Rock, we pulled up a heaved, unpermitted concrete apron and found the rear patio slab poured years ago over uncompacted fill. The homeowner wanted a Brussels Block patio tied to the back door. We over-excavated the fill, re-compacted in lifts, set a geotextile-separated base with a positive drain away from the shallow footing, and installed Brussels Block with polymeric joint sand and aluminum edge restraint. The patio now sheds winter rain away from the bungalow’s pier-and-post foundation instead of puddling against it. If the details aren’t right on paper, they won’t be right in the wall – or under the paver.
Unilock Models & Products We Service in San Jose
We work with the full Unilock line as an independent installer. Brussels Block is the workhorse we see most on San Jose driveways and patios, its tumbled edges look right against a 1920s bungalow or a 1970s ranch tract home. Uni-Stone and Holland Stone show up on older walkways and aprons, and Beacon Hill is a popular choice for newer additions and second-story projects where the homeowner wants a heavier, more architectural paver. We stock genuine Unilock units locally and spec Unilock-compatible joint sand and edge restraint, so a repair or new install in San Jose doesn’t stall waiting on a truck from the East Coast. When the existing field just settled or lost sand, we reset and re-sand. When units are cracked or the base is gone, we tell you replacement is the honest answer. We do the same with our wider Unilock sales & service work across the region.

FAQs – Unilock Construction in San Jose
They can, but only if the concrete is structurally sound, level, and drained correctly. On San Jose’s older bungalow lots, an existing patio slab is just as likely to be an unpermitted pour over bad fill, and laying Unilock pavers over that is building on a problem. We evaluate the slab condition and the base beneath it before recommending overlay or over-excavation. Call (877) 752-3154 and we’ll take a look.
Your joints are washing out because water is moving through the paver field instead of away from it. That usually traces back to a base that was never over-excavated and drained, or edge restraint that’s failing and letting the field spread. On San Jose’s clay-heavy valley floor, the fix is to rebuild the base with proper drainage and re-sand with a high-quality polymeric joint sand. Call (877) 752-3154 for an exact diagnosis.
Most paver patio installs don’t trigger a permit, but in San Jose, a paver driveway replacement or a significant expansion can fall under the city’s detailed planning review. If the existing concrete was unpermitted, we’ll flag it before we touch anything. We handle permitting as part of the project, so you’re not left sorting it out with the city. Call (877) 752-3154 and we’ll walk you through what applies to your lot.
The answer is over-excavation, a geotextile separator between the subgrade and the aggregate base, and compaction in lifts. San Jose’s expansive clay moves through the wet-dry cycle, and a thin base with no separator lets that movement telegraph straight up through the pavers. We build the base like it’s the part you’ll never see but always feel. Call (877) 752-3154 for a free estimate on your driveway.
Yes, and this is where using genuine Unilock units matters. Brussels Block has a distinctive tumbled edge and color blend that generic pavers can’t match. We keep local stock of the common Brussels Block colors, and we’ll order the exact blend your field uses if we need to match a specific batch. The repair won’t look like a patch. Call (877) 752-3154 and we’ll match it.
