Unilock Driveway & Pavers Nationwide

Unilock Driveway & Pavers: The Sherman Oaks Owner’s Guide

Unilock paver driveway repair and replacement in Sherman Oaks typically runs $7,000-$18,000 for a full installation, with partial repairs starting around $2,500 depending on the series and substrate condition. We stock Unilock-compatible edge restraints, joint sand, and base material on our Sherman Oaks trucks, and most paver resets or edge repairs are completed in one working day. Most homeowners notice the problem first as a wobble underfoot, a spreading joint gap, or water pooling where the pitch used to drain - signs that the bedding sand has shifted or the edge restraint has failed, letting the field pavers migrate.

Which Unilock Models This Applies To

Unilock’s residential driveway lines fall into three categories we see regularly in Sherman Oaks: the Brussels Block series with its tumbled finish and beveled edge, the Hollandstone line with its rectangular 4×8 profile, and the more recent Beacon Hill Flagstone with its dimensional texture. Each uses a different edge restraint profile - Brussels Block typically needs the 8-inch aluminum edging with 10-inch spikes on curves, while Hollandstone can sometimes keep its shape with plastic paver edging if the bed is stable.

To identify your exact series, flip a loose paver (if you have one) and look for the Unilock stamp on the bedding face - the manufacturing date code tells us which batch formula was used, and that affects joint sand compatibility. The pre-2018 Brussels Block used a slightly more porous concrete mix that absorbs polymeric sand differently than post-2018 production. We carry both the OEM Unilock polymeric sand and a vetted aftermarket equivalent from Techniseal that performs identically in Sherman Oaks’ clay-heavy soil conditions, and we’ll note which we’re using on your written quote before any work starts.

Signs Your Unilock Driveway & Pavers Is Failing

• Individual pavers rock or sink when stepped on. This usually means the bedding sand layer has washed out or compacted unevenly, often from irrigation runoff hitting the same spot repeatedly. In Sherman Oaks, we see this most on north-facing driveways where morning moisture lingers.
• Joint sand is missing or weeds are growing through. Polymeric sand breaks down faster when subjected to pressure washing or when the wrong sand grade was used originally. The gap lets water penetrate to the base, accelerating the failure.
• Edge pavers are spreading or the border line is no longer straight. The edge restraint has either pulled its spikes or rotted if plastic was used in a high-moisture zone. Once the edge goes, the field follows within a season or two.
• Water pools where it used to drain. This indicates base settlement or erosion, sometimes from a broken sprinkler line underneath. The paver surface itself may be intact, but the structural bed has failed.
• Chipping or spalling on the paver surface. Unilock’s surface color layer is roughly 3/16 inch thick; once that’s compromised, the gray concrete body shows through. De-icing salt accelerates this, though it’s less common in Sherman Oaks than in the Midwest.

Replacement Cost & What’s Included

A full Unilock paver driveway replacement in Sherman Oaks runs $7,000-$18,000, with the spread driven by square footage, base repair depth, and whether we need to match a discontinued color. Partial repairs - resetting a settled section, replacing edge restraints, or re-bedding a 200-square-foot area - typically fall in the $2,500-$5,500 range.

Every quote breaks out materials, labor, and base work separately. We pull permits when the project scope requires it, and every job carries our 365-Day Done Right Promise under The Haven Standard. Under Clause 1, the price is written before anyone starts - no change proceeds without a signed change order, which is the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007. You’ll receive a documented photo record of the excavation and base prep, included as standard.

DIY or Call Us?

An owner can safely check whether a paver is loose by hand and verify the Unilock stamp on the underside. What goes wrong fast is the excavation: removing failed bedding sand without disturbing the compacted base layer requires a light touch and the right depth gauge. Too aggressive, and you’re buying base rock you didn’t need. Too shallow, and the new bed won’t drain.

The real risk is structural. A driveway sees vehicle loads; a patio reset that looks fine can fail in six months under a 4,000-pound truck. We compact the base in 6-inch lifts with a plate compactor rated for the application, not a hand tamper.
