Unilock Construction in San Jose, CA

Unilock Construction in San Jose, CA | Seaside Contractors

We install and service Unilock paver patios, driveways, and retaining walls across San Jose, with real experience on the tight, built-out lots that define this city’s housing stock. What separates our Unilock work here is simple: we plan base excavation and field layout around San Jose’s heritage-tree ordinance, setback rules, and infill realities before a single paver goes down. We’re an independent hardscape contractor, not manufacturer-authorized, which means our recommendations are driven by what works on your lot, not by a dealership agreement.

Why San Jose Residents Choose Us for Unilock Service

We know the Unilock catalog, but more importantly, we know how these pavers behave on San Jose’s clay-heavy, fully built-out parcels. Our crew has installed Brussels Block, Beacon Hill Flagstone, Bristol Valley, and the Pisa2 and Olde Quarry retaining wall systems across the core ZIPs, so when a problem shows up, we’ve usually seen it before. Glen Sorrento, our owner, grew up on the Peninsula watching lagoon-side homes get rebuilt, studied building construction technology at College of San Mateo, and has spent the years since working every trade that touches a hardscape job: drainage, grading, concrete, framing. That breadth matters when your paver patio shares a property line with a 1950s foundation or a protected oak. We use open-graded base, proper edge restraint, and Unilock’s own installation details rather than cutting corners to hit a low bid. And we’re licensed and insured, with a project scope that runs from paver repairs to full garage conversions involving Unilock hardscape transitions.

Common Unilock Construction Problems We Solve in San Jose

• Joint sand washout after a wet winter. San Jose’s winter rains find every weakness in a paver field that was installed over a compacted-clay base with no drainage. We see this on older 1940s-1970s homes where the patio was pitched toward the house rather than away from it. We excavate, re-grade with an open-graded base, and re-set the joints with polymeric sand to handle the next rainy season.
• Rutting and lipping at driveway aprons on 95110-95113 parcels. Narrow lots with short driveways often had pavers laid directly over old concrete, and years of vehicle load plus clay soil movement create shifted edges and trip hazards. We pull the failed section, excavate to proper depth, compact a new base, and re-set the same units if they’re still sound, or match new Unilock if they’re not.
• Bulging and migration on Pisa2-style wall units. Retaining walls behind raised patios on tight side yards fail when geogrid wasn’t spec’d into the design. We rebuild the wall with grid reinforcement, proper drainage, and correctly set Unilock units, so the wall holds its line through another decade of dry-summer/wet-winter cycles.
• Efflorescence and joint staining on tumbled Brussels Block. When a patio is pitched toward the stucco rancher’s foundation, water pools, minerals wick up through the pavers, and joints stain. The fix is drainage first: we re-grade the field slope, add a channel drain if needed, then clean and re-sand.
• Base failure across an entire paver run. Sometimes it’s not a repair. If the base was never compacted properly and the whole field has settled unevenly, we’ll recommend full replacement with a correctly built open-graded base. We’ll tell you straight, because Glen’s rule stands: let’s figure out what the job actually needs, then we’ll talk materials.

Unilock Service in San Jose: What Local Conditions Mean for Your Hardscape

San Jose’s heritage-tree ordinance is the quiet constraint that reshapes more paver projects than any design trend. A mature oak or redwood in a 95111 or 95112 backyard can require a city permit and arborist review before a lot-split or addition moves forward, and since paver patios and driveways are often the first ground disturbance on the site, the root-protection zone is our starting point. We lay out the Unilock field and base excavation around those protected root zones, keeping compaction and trenching outside the drip line so the arborist review doesn’t stall your whole remodel. That’s a level of site awareness a greenfield job in a newer suburb never has to deal with, and it’s exactly why a generic paver installation approach fails here. On a narrow 95112 lot off the Naglee Park grid, our crew was asked to redo a cracked-concrete patio behind a 1950s stucco rancher while the owner was pulling permits for a detached-garage ADU conversion. We excavated to an open-graded base, set a Unilock Brussels Block field with polymeric sand, and detailed the edge restraint to shed water away from the new ADU footing, all while keeping excavation outside the drip line of the yard’s mature oak so the tree-protection review wouldn’t stall the job.

Unilock Models & Products We Service in San Jose

We work with the full Unilock residential line that makes sense for San Jose’s housing stock: Brussels Block for its tumbled, settled-in look on patios and walkways, Beacon Hill Flagstone where a flagstone appearance fits the mid-century rancher aesthetic, and Bristol Valley for cobble-scale driveways that need to handle vehicle load on short, narrow aprons. For retaining walls, we service Pisa2 and Olde Quarry systems, including rebuilds where geogrid or base correction is required. We stock OEM-compatible materials locally, which means we’re not waiting on a distributor truck from out of state to start your San Jose repair. When a paver field is sound, we lift, clean, and re-set units on corrected base. We only recommend full replacement when the base has failed across the whole run, and we’ll show you why.

FAQs – Unilock Construction in San Jose

Does San Jose’s tree ordinance affect where I can put a Unilock patio?

Yes. If a mature oak or redwood sits in your yard, San Jose’s heritage-tree rules require a permit and arborist review before excavation within the tree’s root-protection zone. We design the paver field and base work around those protected roots so the permit process doesn’t stall your project. Call (833) 589-8103 and we’ll walk your lot before you commit to a layout.

Can a Unilock driveway work on a narrow 95110-95113 infill lot?

It can, but it depends on the base more than the paver. Those older parcels often had concrete poured over clay without proper sub-base prep. We excavate the existing slab, compact an open-graded base, and set the Unilock driveway with correct edge restraint so it handles vehicle load without rutting. The width of the lot doesn’t stop the work; the prep does.

Why do San Jose paver joints wash out after winter?

Because San Jose gets almost all its rain in a short December-to-February window, and if the field wasn’t graded with an open-graded base and a drainage path, that water sits in the joints and washes the sand out. We re-grade the slope, correct the base, and use polymeric sand that resists runoff. Call (833) 589-8103 if your joints are already washing out, spring is the right time to fix it before the dry season.

Is a Unilock retaining wall behind a raised patio a separate permit item in San Jose?

Usually yes. San Jose treats retaining walls over a certain height as a separate permitting item, and when it’s tied to a raised patio or an ADU addition, the city wants to see the structural detail. We handle the permit as part of the project scope, and we spec the geogrid and drainage the wall actually needs, because a bulging Pisa2 wall is almost always a missing-grid problem.

Can I reuse existing Unilock pavers when we rebuild the base?

In most cases, yes. We lift, clean, and re-set sound units on corrected base, which saves you material cost. If some units are chipped or cracked from base failure, we’ll match replacements from the same Unilock line. If the whole field has failed, we’ll be straight with you about whether repair or replacement makes more sense.
