Unilock Construction in San Jose, CA | Penhallow Remodeling
We’re a General Contractor in San Jose and independent Unilock service provider handling paver driveways, patios, and wall systems across the city. What sets our Unilock work here apart is this: we plan every installation around the city’s permit backlog and seismic mapping, which means your Brussels Block driveway gets engineered for the ground it actually sits on, not just the pattern it’s laid in. We bid, prep, and install Unilock products against engineered plans for ADUs, retrofits, and high-end hardscape. Call (936) 259-2607 for a written estimate before any work begins.
Why San Jose Residents Choose Us for Unilock Service
Unilock pavers and walls are precise products. A millimeter of variance in a base layer becomes a wobbling paver six months later. We know those tolerances because we’ve worked with them daily across San Jose’s neighborhoods, from Cambrian tract lots to Alviso’s bay-adjacent ground. Trevor Nash, our owner, spent the better part of two decades working residential projects across California before starting Penhallow Remodeling and building expertise in our Bathroom Remodeling in San Jose, and he built this company around one habit: put the price and the guarantee in writing before a single paver gets set. That means you get a written number, a defined arrival window, and our 365-Day Done Right Promise on every Unilock project we take on.
We’re not a manufacturer-authorized dealer, and we’ll tell you that straight. What we are is a local contractor who knows Unilock product lines well enough to source genuine pavers, caps, and compatible polymeric joint sand rather than mismatched aftermarket lookalikes. Color and dimensional consistency matter once a field is partly set. When you call Penhallow Remodeling, a live person answers, 24/7. The technicians who show up are background-checked and uniformed. And the price we quote is the price on your invoice.
Common Unilock Construction Problems We Solve in San Jose
- Liquefaction-zone settlement in Alviso and North First Street. Unilock paver driveways and patios in these mapped hazard zones sink or heave when the base preparation doesn’t account for settlement risk. We rebuild on engineered pier-and-grade-beam or post-tensioned slab foundations, then reset the pavers on compacted aggregate.
- Calaveras Fault movement in Alum Rock and East Foothills. Fault-setback compliance is a routine permit issue here, and the ground shifts in ways that crack Unilock retaining wall caps and shift pavers. We engineer walls for lateral movement, not just vertical load.
- Clay-soil expansion in East San Jose, Berryessa, and Cambrian. Those 1950s to 1970s tract yards sit on expansive soils that push Unilock Brussels Block and Copthorne joints out of alignment after wet winters. The fix starts with deeper base excavation and proper drainage, not just re-sanding.
- UV fading and surface scuffing on Umbriano and Beacon Hill. San Jose’s dry Mediterranean summers are brutal on unsealed surfaces. We apply the right sealer and joint sand so your pavers hold their color instead of chalking after two seasons.
- Permit-tied project stalls. Hardscape work tied to an ADU or seismic retrofit often waits on city approval. We sequence Unilock installation around San Jose’s pre-approved ADU plan library timeline, not the other way around.
Unilock Service in San Jose: What Local Conditions Mean for Your Equipment
Here’s the thing about Unilock work in San Jose that a generic service page won’t tell you: the city’s residential permit office is notoriously backed up, with standard reviews routinely taking 6 to 12 months. For a paver driveway or patio tied to an ADU addition or a soft-story retrofit, that means your Unilock installation can’t simply start when the crew is ready. It starts when the permit clears. Our team plans the hardscape sequencing around the city’s pre-approved ADU standard plan library, which can cut approval time to 2 to 4 weeks when your project qualifies. That permitting fluency, more than anything else, determines whether a summer paver project actually gets built that same summer. In Alviso, near the North First Street corridor, we rebuilt a Unilock Brussels Block driveway on an engineered pier-and-grade-beam base after the original installation settled in a mapped liquefaction zone. The homeowner watched that driveway open up over two wet seasons. With proper base depth and joint stabilization, the field has stayed level through the following winter.
That project taught us something we already suspected: in San Jose, the ground is never neutral. Between the Calaveras Fault running through Alum Rock and the settlement zones along the bay, the number of ways a poorly prepared base can fail is longer than any material warranty. We plan for that before the first paver arrives.
Unilock Models & Products We Service in San Jose
We work across the Unilock product lines most common in San Jose residential work: Brussels Block for driveways and walkways that need a classic tumbled look, Beacon Hill for patios with a smoother, more contemporary finish, Umbriano for high-end outdoor spaces with a non-slip surface, and Copthorne for traditional hardscape with a timeworn feel. When a repair calls for new units, we source genuine Unilock products so the color and dimensions match the original field. If a installation fails only at the base or joint level, we repair and re-level. If the failure is widespread settlement or structural wall cracking, we recommend full replacement over patching. We stock the compatible polymeric joint sand and base materials locally for faster turnaround across San Jose.

FAQs – Unilock Construction in San Jose
Yes, but only with the right base. In mapped liquefaction zones like Alviso and the North First Street corridor, a standard gravel base will settle and open up paver joints within a season or two. We install Unilock pavers on an engineered pier-and-grade-beam or equivalent system designed for ground movement. The pavers stay level because the base underneath them isn’t moving. Call (936) 259-2607 and we’ll walk your site before quoting anything.
Yes, but the wall and base design changes. Fault-setback zones in Alum Rock and East Foothills require retaining walls engineered for lateral movement, not just static load. We’ve installed Unilock wall systems in these areas with the right drainage and reinforcement to handle ground shift. It costs more than a standard wall, and skipping that engineering is how caps crack. We include the engineering in our written quote.
Standard residential permits in San Jose routinely take 6 to 12 months through city review. If your hardscape project is tied to an ADU or retrofit that qualifies for the city’s pre-approved plan library, approval can drop to 2 to 4 weeks. We handle the sequencing so your Unilock installation starts when the permit clears, not before. Call (936) 259-2607 and we’ll tell you which path your project falls under.
Polymeric joint sand is the only option that survives San Jose’s heat and UV. Standard sand washes out in the first winter and UV-bakes into dust by August. We use a compatible polymeric sand that hardens to lock pavers in place and resists fading. It’s one of the details that keeps a Unilock patio looking clean through a full year of San Jose sun.
If the settlement is localized, a repair and re-level makes sense. Cambrian’s expansive clay soils push individual pavers out of alignment after wet winters, and we can lift, re-base, and reset those sections. But if the entire field is shifting or the base has washed out, full replacement on a properly engineered base costs less over time than repeated patching. We’ll tell you honestly which applies to your patio. Call (936) 259-2607 for a free site assessment.
