Unilock Driveway & Pavers: The San Jose Owner’s Guide
Unilock driveway and paver installation in San Jose typically runs $8,260 to $21,240 depending on square footage, base preparation, and the specific Unilock product line. We stock Unilock-compatible pavers and edge restraints on our trucks, and most paver repair or partial replacement jobs can be quoted within one visit. The way most San Jose homeowners discover a problem is the same: a paver sinks after the winter rains, an edge restraint pops loose near the sidewalk, or a section of the driveway shifts because the base underneath finally gave out.
We’re an independent San Jose contractor, not a Unilock dealer or affiliate. That matters because our recommendation isn’t tied to moving one product line. When a Unilock paver fails, the paver itself is rarely the culprit. It’s almost always what’s underneath it.
Which Unilock Models This Applies To
Unilock breaks its driveway and paver lines into a few families, and the compatibility question comes down to thickness and manufacturing tolerance. The Estate line (Courtstone, Richcliff, Beacon Hill Flagstone) is the workhorse for San Jose driveways because the 60mm to 80mm thickness holds up under vehicle weight. The U-Cara multi-piece wall system and Brussels Block pavers show up on a lot of patios and walkways, but they’re not rated for repeated vehicle traffic the way the Estate products are.
The compatibility gotcha we see on San Jose jobs: older Unilock pavers installed before roughly 2010 often measure slightly smaller than current production of the same named product. A Courtstone paver from a 2008 install won’t always sit flush against a 2024 Courtstone paver from a fresh pallet. If you’re patching a section, we want to measure the existing paver with calipers before ordering, not just match the name. For OEM versus aftermarket: Unilock’s color blends are proprietary, so a generic paver from a big-box store will never match a weathered Unilock surface. Aftermarket edge restraints and bedding sand, on the other hand, are commodity products where generic works fine.

Signs Your Unilock Driveway & Pavers Are Failing
- Sunken or dipped pavers in the wheel tracks. This is almost always base failure, not paver failure. The compacted aggregate underneath has settled, eroded, or was never thick enough for clay-heavy San Jose soil. The pavers themselves are fine; what’s beneath them isn’t.
- Loose edge pavers along the driveway border. The plastic or aluminum edge restraint has popped its spikes or cracked. When the edge lets go, the entire field of pavers starts drifting outward, and within a season you’ll see gaps open between rows.
- Weeds pushing up through joints every few weeks. Polymeric sand worked when it was installed, but San Jose’s wet winters followed by dry summers break down the binder. Once the joints open, water gets under the pavers and accelerates base erosion.
- Standing water or dark stained patches. A failing base traps water instead of draining it, and the moisture wicks up through the paver joints. In San Jose’s clay soil, poor drainage under pavers is the single most common cause of premature failure.
- Crumbling or chipped paver edges near the driveway apron. The apron takes the impact from tires turning. If the base at that transition point wasn’t reinforced, the pavers flex and crack at the corners within a few years.

AfterReplacement Cost & What’s Included
For a full paver driveway installation in San Jose, expect $8,260 to $21,240. Partial repairs and section replacements typically land between $1,500 and $6,000 depending on square footage, base reconstruction, and whether we’re matching a discontinued Unilock color. What drives the number: excavation depth (San Jose clay usually needs 6 to 8 inches of compacted base), paver thickness (60mm versus 80mm), pattern complexity, and access for equipment. A straight driveway with easy dump truck access costs less than a curved driveway behind a retaining wall.
Our written price includes the pavers, bedding sand, edge restraints, base material, haul-away of the old surface, and a full year under the 365-Day Done Right Promise. If something shifts or settles within that year, we return and fix it at no cost, with no service call fee. The number on day one is the number on the invoice.

DIY or Call Us?
You can safely inspect a few things yourself: look at the edge restraints to see if they’ve pulled away from the pavers, check whether the joints still have polymeric sand in them, and hose down the driveway to see where water pools. Those observations help you describe the problem accurately when you call. What you shouldn’t attempt is digging out sunken pavers and re-laying them without recompacting the base. That’s how San Jose driveways end up worse than they started. The pavers go back in, they look fine for six weeks, and then the same dip returns because the real problem was six inches underneath.
If the edges are intact and only a few joints need re-sanding, that’s a reasonable weekend job. If the base has failed or the edges are drifting, that’s the point where a partial redo costs less than guessing wrong twice. Call (669) 274-2362 and we’ll look at it with you.
FAQs
Unilock pavers themselves typically last 25 to 40 years in San Jose’s climate, but the base underneath is the real lifespan limiter. In local clay soil with seasonal wet and dry cycles, bases installed without proper compaction or drainage can fail in 8 to 12 years. A well-built base with good drainage extends the whole system’s life well past the paver’s own lifespan. Call (669) 274-2362 for a free on-site assessment.
Yes, in most cases sunken sections can be lifted, the base re-leveled and recompacted, and the same pavers reinstalled. The pavers are rarely damaged; they just need to be pulled up, set aside, and put back over a stable base. This repair typically costs $1,500 to $4,000 depending on section size and base condition. If the base has eroded significantly, we’ll show you exactly what we’re seeing before we touch anything.
A typical section repair takes one to two days on site. A full driveway replacement takes three to five days including base excavation, compaction, paver installation, and joint sanding. We give you the time window in writing before work starts, along with the written price.
We stock common Unilock-compatible edge restraints, bedding sand, and polymeric joint sand on every truck. Pavers themselves are ordered per job because the color and size matching depends on your existing install. We also work with KraftMaid, Cambria, and Silestone products on our remodeling side, but driveway and paver projects get Unilock-specific materials.
If you’ve got a Unilock driveway in San Jose that’s sinking, drifting, or losing joints, give me the real problem and I’ll give you the real number. Call (669) 274-2362 for a free estimate and a written price before any work begins.
