Unilock Construction in San Jose, CA
We install and repair Unilock paver systems across San Jose, from Buena Vista to Brussels Block driveways in Willow Glen and Estate Wall retaining walls on tight Northside lots. As an independent hardscape crew, we’re not affiliated with or authorized by Unilock, but we’ve laid and torn out enough of their pavers here to know exactly where they fail. The short answer: San Jose’s clay-heavy soils and infill lot drainage patterns are what kill most Unilock installs, and that’s what we fix. Call (877) 373-9230 for a free estimate on your paver project.

Why San Jose Residents Choose Us for Unilock Service
Noel Cardenas grew up in Garden Grove and built his career on the idea that the material you pick today is the problem you solve, or the one you live with, ten years from now. That’s how we approach Unilock work in San Jose. We’re not a manufacturer authorized dealer pushing one product line. We’re a general contractor that specs Unilock when it’s the right paver for the job, and we’re honest when it isn’t. San Jose homeowners call us because we carry the full Unilock knowledge base without the factory showroom pitch. We match your existing field with Unilock’s own replacement pavers, set edge restraint in concrete like the manufacturer requires, and re-base on compacted aggregate with geotextile instead of the half-inch of sand some guys use. That’s the difference between a driveway that drains and one that pools.

Common Unilock Construction Problems We Solve in San Jose
- Settled and rocking pavers at the driveway apron. San Jose’s clay soil expands when wet and shrinks when dry. If the aggregate base was too thin or over-compacted, the pavers shift within a season. We see it constantly on older Rose Garden homes where the driveway meets the street.
- Winter rain pooling under the paver field. Failed polymeric joint sand lets water sit beneath the surface instead of shedding to the street or a drain. San Jose’s wet winter season turns this into a leak and drainage call by February.
- Edge restraint failure at driveway entrances. Border pavers that were never set in concrete, or were set too shallow, walk out under tire pressure. The field spreads and the clean edge disappears on Willow Glen driveways that see daily traffic.
- Efflorescence and shallow spalling on pavers over intact slabs. Older San Jose bungalows often had concrete slabs paved over with Unilock and no drainage path. The trapped moisture leaves white mineral staining and surface flaking.
- Unpermitted additions triggering hardscape teardowns. San Jose’s 1980s-90s tech boom left a lot of converted garages and unpermitted work. When a remodel goes to permit, the paver field is often the first thing scraped for lot-split or ADU setbacks.
Unilock Service in San Jose: What Local Conditions Mean for Your Project
Here’s what makes San Jose different from neighboring cities: on a 5,000 to 6,000 square foot lot, you’re usually paving the strip between the house and the property line. There is no room for a swale. That means a Unilock driveway in San Jose has to be spec’d to drain to a low point or a catch basin, not overland. We build paver fields that fall to a channel drain at the apron or to a basin in the side yard, because the alternative is water running toward the foundation. On a Willow Glen bungalow near Seven Trees, we pulled a Brussels Block driveway that had been laid over an existing slab with a half-inch of sand and no restraint. Winter rains pooled against the garage. We broke out the slab, re-based on compacted aggregate with geotextile and concrete-set edge restraint, and re-laid the Brussels Block to fall to a new channel drain at the apron. No more standing water, and the borders stayed put through the next wet season. That’s what drainage-first Unilock work looks like in San Jose.
Unilock Models & Products We Service in San Jose
We work with the Brussels Block line, the tumbled classic that’s everywhere in San Jose’s older neighborhoods. Thornbury, the larger estate-scale paver, shows up on Willow Glen and Rose Garden properties with bigger front yards. Beacon Hill, the smooth contemporary paver, fits the clean lines of newer Northside builds. For retaining walls, we install and repair the Estate Wall system. On parts, we use Unilock’s own matching pavers, manufacturer-spec polymeric sand, and concrete-set edge restraint. For base and drainage, we spec washed aggregate, geotextile, and proper channel drains rather than cheap substitutes. If you need a specific Unilock color or profile matched, call (877) 373-9230 and we’ll track it down.

AfterUnilock Service Pricing in San Jose
Your final cost depends on the square footage, whether we’re re-basing or laying over fresh ground, and how much drainage infrastructure your lot needs. Here are the ranges we quote in San Jose:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $8,260 – $21,240 |
| Paver Patio Installation | $4,130 – $12,980 |
| Driveway Replacement | $5,900 – $16,520 |
| Driveway Sealing | $295 – $825 |
The biggest variable is what’s under the pavers. If the base is gone and the field has lost its edge, re-laying over the old base is a two-year fix, not a ten-year one. We’ll quote the full re-base instead of masking it. Every estimate includes a site walk, a written line-item quote, and a drainage assessment. Call (877) 373-9230 for your free estimate.

FAQs – Unilock Construction in San Jose
In most San Jose cases, no. The existing slab prevents drainage, traps moisture under the pavers, and leads to efflorescence and spalling. We recommend breaking out the slab and re-basing properly.
For most paver driveways and patios, no, but if your lot has drainage requirements or you’re combining the work with an ADU or lot-split, the city may require a drainage plan. We’ll tell you before we start. Call (877) 373-9230 and we’ll check your specific street.
San Jose’s clay soil expands and contracts with moisture, and if the base was too thin or over-compacted, the pavers shift. This is the most common Unilock failure we repair here. Call (877) 373-9230 for an exact diagnosis, estimates are free.
Expect $8,260 to $21,240 depending on square footage, drainage needs, and whether we’re re-basing. A free estimate gives you a locked line-item price before work starts. Call (877) 373-9230.
That points to a base and drainage problem, not just the pavers. We assess the fall, the edge restraint, and the drainage path, then spec a fix that sheds water to a low point or channel drain. Call (877) 373-9230 for a drainage check.
