Why San Jose Residents Choose Us for Unilock Service
San Jose has two kinds of homes: the 1950s ranch with a cracked concrete walkway, and the Eichler-inspired courtyard where every design choice is on display. We work on both. Trevor Nash, who runs our San Jose crew, spent years on kitchen and bath gut-jobs in Willow Glen, and he brings the same eye for substrate and drainage to hardscape. We’re not a landscaping company that dabbles in pavers. We’re a General Contractor in San Jose that understands what happens underneath the paver, and in San Jose, what’s underneath is usually expansive clay.
We use Unilock’s own matching pavers and wall units when color and texture matching matter, and we stock common lines locally for faster turnaround. But we’ll also recommend high-quality compatible polymeric sand and edge restraints from proven suppliers when they hold up better to San Jose’s dry-summer, wet-winter cycle. You get an independent opinion, not a manufacturer script. Our Unilock sales & service experience runs deeper than most because we see these products after ten years of drought, not just on day one.

Common Unilock Construction Problems We Solve in San Jose
San Jose’s climate and soil create specific failure patterns in Unilock installations. Here’s what we see and what we do about it:
- Polymeric sand erosion in paver joints. San Jose’s long rainless summers bake the sand, then heavy winter rains wash it out. You get weeds, ants, and pavers that shift underfoot. We remove the failed sand, inspect the base, and re-sand with a product rated for wet-dry cycling.
- Efflorescence on Unilock concrete pavers. Willow Glen landscapes with irrigation overspray and hard water leave white mineral deposits on Brussels Block and Lineo surfaces. This isn’t product failure. It’s a chemistry problem we clean and then address by adjusting spray patterns or adding a breathable sealer.
- Settling and lippage on patios over expansive clay. Drought shrink-swell cycles create voids under paver bases. You’ll see low spots, raised edges, and a “lipped” look. We lift the affected section, re-compact the base, and relay with the original pattern intact.
- Cracked or spalled paver edges on older driveways. San Jose’s narrow 1950s driveways were never designed for today’s heavier vehicles. When the base is too shallow, pavers crack under load. We rebuild the base to driveway spec before any new Unilock paver goes down.
- Failed edge restraints on sloped lots. East side tract homes and hillside properties near Los Gatos put real lateral pressure on driveways and walkways. When plastic edging fails, the field creeps outward. We re-pin with steel or aluminum restraints anchored to the slab.
Unilock Service in San Jose: What Local Conditions Mean for Your Equipment
Here’s something specific to San Jose that most generic Unilock pages won’t tell you: the Citywide Design Guidelines and many Eichler neighborhood covenants limit front-yard hardscape to a percentage of lot coverage. If you want a driveway expansion or a wider front walk on an Eichler lot, you often can’t pour more concrete without triggering a drainage variance. Unilock’s permeable lines, like Eco-Priora, change that math. Water moves through the joints into a crushed rock reservoir below, so the impervious surface calculation stays under the limit. We’ve used this approach on Eichler courtyards in the Fairglen tract and on ranch lots near Lincoln Avenue where the city required stormwater mitigation. It’s not just about aesthetics. It’s about getting the permit approved at all.
Unilock Models & Products We Service in San Jose
We work on the full Unilock hardscape lineup you’re likely to find in San Jose, including Brussels Block, Lineo Dimensional Stone, Rivercrest Wall, and U-Cara Multi-Face Wall System. Each has its own failure profile here. Brussels Block shows efflorescence on sprinkler-fed lawns. Lineo’s longer format exposes base issues faster because it has less internal give. Rivercrest and U-Cara hold up on retaining walls, but they’re only as good as the geogrid and drainage behind them. When we replace a single damaged unit, we match color and texture from Unilock’s current production. If more than 30% of a paver field is damaged or the base has failed, we recommend a new base and relay rather than piecemeal patching. That’s the honest math.

FAQs – Unilock Construction in San Jose
Yes, if the base is built correctly. Brussels Block is a durable paver, but no paver survives a base that flexes. San Jose’s expansive clay requires more excavation and more compacted aggregate than a standard install. We over-excavate by 2 to 4 inches on clay-heavy lots and use a geotextile separator. That’s the difference between a patio that lasts two seasons and one that lasts twenty. Call (669) 274-2362 for an exact quote on your lot.
U-Cara is a face system, not a structural retaining wall on its own. At 3 feet of grade, you need geogrid reinforcement and proper drainage behind any wall system, including Rivercrest. We connect U-Cara units to a reinforced block core and install a perforated drain at the base. Skip those steps and the wall leans within a few years. We won’t build it without them.
That’s efflorescence, and it’s common on newly installed concrete pavers in San Jose where irrigation overspray meets hard water. Minerals migrate to the surface and leave a white film. It’s cosmetic, not structural. We clean it and address the water source. If the paver was just installed, it often fades on its own as the concrete cures. If it’s been a year, we treat it. Call (669) 274-2362 and we’ll tell you which situation you have.
We don’t patch the low spot and walk away. We pull the affected area, inspect the base, and determine whether the subgrade is the problem or the base depth was insufficient for driveway loads. On older San Jose ranches, the original base is often crushed rock over clay, and it was never rated for modern vehicles. We excavate to a proper depth, re-compact, and relay. If the whole driveway is failing, we recommend a full replacement rather than endless spot repairs.
