Unilock Driveway & Pavers Nationwide

Unilock Driveway & Pavers: The West Palm Beach Owner’s Guide

We stock and install Unilock-compatible driveway pavers and retaining wall systems in West Palm Beach, with paver driveway installations typically running $7,000-$18,000 depending on pattern complexity and base preparation needs. Most Unilock Beacon Hill Flagstone, Brussels Block, and Richcliff pattern repairs can be assessed same-day, and we carry common edge restraints, joint sand, and replacement units on our trucks. Homeowners usually notice the problem first as shifting or sinking after heavy rain, or as weeds pushing through joints that used to stay tight - both signs that the bedding layer or edge restraint has failed.

Which Unilock Models This Applies To

Unilock organizes its residential hardscape line into series that share base construction methods but differ in surface texture and unit thickness. The EnduraColor series - Beacon Hill Flagstone, Bristol Valley, and Copthorne - uses a two-layer manufacturing process with a color-wearing surface over a structural body, which means replacement units must match both the pattern name and the vintage, since Unilock has adjusted surface formulations twice in the past decade. The Umbriano and Series lines are single-layer through-body color, more forgiving for patch repairs.

To identify your exact unit, check the pallet label if you have leftover stock, or measure a single paver: Beacon Hill runs 6×9 inches and 2⅜ inches thick, while Brussels Block is 8×6 inches with a tumbled edge profile that aftermarket suppliers rarely replicate accurately. We source OEM Unilock units through their Florida distribution network rather than generic equivalents, because the dimensional tolerances - particularly on the spacer bars molded into Brussels Block - affect joint width and long-term interlock. Generic “tumbled cobble” pavers from big-box suppliers are typically 1/16 to 1/8 inch oversize, which opens joints and accelerates bedding sand washout.

Signs Your Unilock Driveway & Pavers Is Failing

• Sinking or tilting after rain. Water has penetrated the joint sand and eroded the limestone screening base beneath. In West Palm Beach, our summer downpours move a surprising volume of water through open joints in a single storm.
• Weeds or ant mounds between units. The polymeric sand jointing material has degraded or was never installed; organic matter accumulates, roots find purchase, and the freeze-thaw cycle - rare here, but real in January cold snaps - widens gaps.
• Chipping at unit corners, especially on driveway edges. This is usually a failed edge restraint; the flexible PVC or aluminum edging that locks the field pavers in place has rotted, pulled its spikes, or been driven over by heavy vehicles.
• White haze or efflorescence blooming on the surface. Calcium salts from the concrete base migrate through the paver body; it’s cosmetic but indicates moisture is moving through the system rather than draining properly.
• Pavers sounding hollow when tapped. The bedding sand layer has washed out or compacted unevenly, leaving a void. This progresses to cracking under vehicle load, particularly on Unilock’s thinner 2⅜-inch residential units.

Replacement Cost & What’s Included

Repair pricing for Unilock paver systems in West Palm Beach falls into three tiers: joint restoration and sealing at $250-$700, sectional lift-and-relay with base repair at $1,200-$3,500 depending on square footage, and full driveway replacement at $7,000-$18,000. The wide range reflects base condition - if the original installer skipped the 6-inch compacted aggregate base and went with 3 inches of sand over soil, we rebuild to ICPI (Interlocking Concrete Pavement Institute) spec, which adds material but prevents the same failure in five years.

Every repair quote from Rowan Construction Group West Palm Beach is a flat written price with line-item scope: unit count and series, cubic yards of #57 limestone base, bags of polymeric joint sand, and edge restraint linear footage. Under Clause 1 of The Haven Standard, that price is locked before we lift a paver. Our 365-Day Done Right Promise covers settling, joint failure, or edge restraint pullout - if it moves, we return and make it right.

DIY or Call Us?

There’s honest work a homeowner can do: sweep joint sand back in after pressure washing, pull weeds before they seed, and keep gutters directed away from the paver field so water doesn’t undercut edges. But the moment you’re lifting units to address base failure, the job requires plate compaction, laser grading, and an understanding of how the bedding layer thickness - exactly 1 inch of coarse concrete sand - interacts with paver thickness to achieve final grade. Too much sand and the units rock; too little and they crack.

We don’t recommend DIY base repair on any paver system carrying vehicle traffic. The compaction equipment alone runs $80-$120 daily rental, and a hand-tamped base will settle unevenly within two West Palm Beach wet seasons. Call us at (561) 475-3903 and we’ll assess whether a targeted repair or full rebuild makes sense - estimates are free, and we bring a written price, not a sales pitch.
