Unilock Driveway & Pavers Nationwide

Unilock Driveway & Pavers: The San Jose Owner’s Guide

Unilock driveway and paver replacement in San Jose typically runs $8,260-$21,240 for a full paver driveway install, with paver patio work landing at $4,130-$12,980. We stock Unilock-compatible pavers and installation materials, and most San Jose homeowners who call us have already measured their failing section or brought in a photo of the joint pattern. The usual discovery path is straightforward: a sunken tire rut that holds water after rain, weed growth between stones that keeps coming back, or a single cracked paver that spiderwebs under pressure from the garbage truck on collection day.

Which Unilock Models This Applies To

Unilock organizes its residential hardscape line into series that differ in thickness, edge profile, and base-course requirement. The Beacon Hill Flagstone series, common in Almaden Valley installations from 2015-2020, runs 60mm thick with an irregular edge pattern that requires a matching 6-inch compacted aggregate base. The U-Cara face system, popular in Willow Glen front walkways, uses a 35mm facing unit clipped to a structural backing panel - replace the facing and you must verify the clip spacing, which changed in 2019 from 4-inch to 6-inch centers. The Thornbury and Richcliff lines are 80mm driveway-grade units; mixing a 60mm patio paver into a driveway repair is a compatibility gotcha we see twice a year, usually after a homeowner’s first attempt.

To identify your series, flip a loose paver (if you have one) and check the molded stamp on the bedding face. Unilock stamps the series name and manufacturing plant code there. If no loose paver exists, measure thickness at an edge joint and note the surface texture - Richcliff has a cast slate face, Thornbury is smoother with false joints. We carry OEM-equivalent pavers from Unilock’s distribution network and, where color lots have been discontinued, we source from Techo-Bloc or Belgard with documented color-match samples approved before work starts. Rowan Construction Group San Jose is an independent service provider, not affiliated with Unilock.

Signs Your Unilock Driveway & Pavers Is Failing

• Sunken or tilting pavers, especially near the garage apron or street edge. The cause is base erosion from irrigation runoff or a failed edge restraint. In San Jose’s clay-heavy Alviso soils, water pools beneath the bedding course and pumps fines out through the joints over two or three wet seasons. The paver itself is intact; the structure beneath it has left.
• Weeds or moss growing consistently from the same joint lines. This signals joint sand loss, often from polymeric sand that degraded under UV exposure. South-facing driveways in San Jose see this faster - the thermal cycling between 45°F January mornings and 95°F July afternoons breaks down the binder in 4-6 years instead of the advertised 10.
• Pavers that rock under foot or tire load. The bedding course has segregated or washed out locally. This worsens quickly; each rocking motion grinds more sand loose and the void expands. We find this most often where downspouts discharge directly onto the pavement.
• Surface spalling or corner chipping on driveway-grade units. Unilock’s 80mm pavers handle passenger vehicles without issue, but repeated point loading from trailer jacks, RV stabilizers, or contractor dumpsters fractures the face. The damage is cosmetic until water freezes in the crack, which in San Jose happens just often enough to matter.
• Efflorescence that returns after cleaning. White mineral bloom on the surface indicates soluble salts migrating through the paver body. On Unilock’s concrete-based units, this is usually a curing phenomenon that exhausts itself in year one. If it persists in year five, the paver is absorbing moisture from beneath and the base drainage has failed.

Replacement Cost & What’s Included

Partial paver driveway repair in San Jose runs $590-$1,650 per 100 square feet of affected area, depending on base condition and paver availability. Full paver driveway replacement is $8,260-$21,240. Patio and walkway work falls at $4,130-$12,980. The price includes removal of failed material, base recompaction or replacement, bedding course renewal, paver installation with new edge restraint, polymeric joint sand, and vibratory compaction. We pull permits when the project exceeds 200 square feet or alters drainage - San Jose requires this under the municipal code Grant keeps on his nightstand.

What drives the range: paver unit cost varies by series (Richcliff runs higher than Beacon Hill), base depth required for vehicle loading, and whether we need to match a discontinued color lot. Under Clause 1 of the Haven Standard, you receive a written price before any work starts, with line-item breakdown of pavers, base material, labor, and permit fees. The 365-Day Done Right Promise covers the installation. Every visit includes a documented photo record - before, during, and after - delivered by text or email, your preference.

DIY or Call Us?

What a San Jose homeowner can safely check: verify that the paver is actually failed and not just surface-stained, measure the affected area in square feet, and photograph the molded stamp on the bedding face if a loose paver exists. What goes wrong fast: excavating without locating utilities, compacting a base without checking grade for drainage, or installing pavers without edge restraint - the whole field migrates within a season. Polymeric sand application looks simple until you activate it with water at the wrong moment and seal the surface instead of the joints. No safety hazard comparable to electrical or spring work here, but the rework cost on a botched paver job often exceeds the original professional quote.
