Unilock Driveway & Pavers Nationwide

Unilock Driveway & Pavers: The Fort Lauderdale Owner’s Guide

We stock and install Unilock-compatible driveway and paver systems in Fort Lauderdale, with paver driveway installation typically running $7,000-$18,000 and paver patio installation at $3,500-$11,000 depending on substrate condition and pattern complexity. Most Unilock paver resets, base repairs, and joint sand replacements can be scheduled within a few business days, and we carry compatible edge restraints, bedding sand, and polymeric joint sand on our trucks. Homeowners usually discover the failure when pavers shift after heavy rain, sink where the base has washed out, or weeds push through joints that lost their sand - all signs that the interlocking system has broken down somewhere between the surface and the compacted subgrade.

Which Unilock Models This Applies To

Unilock produces several paver lines common in South Florida, and the repair approach differs by series thickness, edge profile, and base specification. The Beacon Hill Flagstone and Richcliff lines are 60mm units often used in Fort Lauderdale driveways where vehicle load matters; these require a 6-inch compacted aggregate base minimum, not the 4-inch bed acceptable for 50mm patio pavers like Brussels Block or Copthorne. To identify your paver, flip a loose unit and check the molded stamp - Unilock marks the series name and manufacturing date code on the underside, visible even on weathered pieces. The joint width also signals the original spec: 1/16-inch joints were set with traditional mason sand, while 1/8-inch or wider joints indicate polymeric sand was specified, and mixing the two during repair causes premature failure. We source OEM-matched Unilock units when available, but for discontinued colors we specify equivalent ASTM C936-compliant pavers from Belgard or Techo-Bloc with documented compressive strength above 8,000 psi - the same spec Unilock publishes, just with honest lead times and no distributor markup passed to the customer.

Signs Your Unilock Driveway & Pavers Is Failing

• Sinking or dipping in wheel paths. This indicates base erosion, usually from insufficient edge restraint or a compromised bedding layer that allowed water to wash fines out from beneath the pavers. In Fort Lauderdale’s sandy soils, a missing or rotted edge restraint lets the whole field migrate toward the low point.
• Weeds growing through joints. Polymeric sand has degraded or was never installed; the joint is now loose enough for organic material to collect and root. Florida’s year-round growing season accelerates this once the binder washes out.
• Pavers rocking underfoot or sounding hollow. The bedding sand layer has settled unevenly or washed away, leaving voids. This happens faster near downspouts or where irrigation overshoots the lawn and pools on the hardscape.
• White haze or efflorescence blooming on the surface. Calcium salts migrating through the paver body, common after heavy rains follow dry spells. It’s cosmetic but signals moisture moving through the system in ways the base should prevent.
• Edge pavers tilting outward or separating from the field. The edge restraint - plastic, aluminum, or concrete - has failed or been undermined. In Victoria Park, we’ve seen this where mature ficus roots push against borders that were installed without adequate setback from the trunk line.

Replacement Cost & What’s Included

For Fort Lauderdale properties, paver driveway installation runs $7,000-$18,000 and paver patio installation $3,500-$11,000; driveway replacement where the base must be fully excavated and recompacted falls in the $5,000-$14,000 range. The spread reflects three variables: paver unit cost (thickness and series), base depth required by soil conditions, and whether we need to haul spoils off-site or can reuse screened material. Smaller repairs - resetting a sunken section, replacing edge restraint, or re-sanding joints - typically fall between $800 and $3,500 depending on square footage. Under Clause 1 of the Haven Standard, every repair quote is a flat written price with line-item breakdown: paver units by series, base material by cubic yard, labor by square foot, and disposal if applicable. The 365-Day Done Right Promise covers settling, joint failure, or edge migration at no charge if our specified base depth and compaction were followed. We don’t bundle - you see what each component costs, and no change proceeds without a signed change order.

DIY or Call Us?

An owner can safely check a few things: lift one paver at the edge to confirm thickness and series stamp, verify whether downspouts discharge directly onto the hardscape, and photograph any edge restraint damage for reference. What goes wrong fast is base work - removing pavers without marking the pattern, skimping on compaction lifts, or using all-purpose sand instead of ASTM C33 concrete sand for the bedding layer. In Fort Lauderdale’s climate, an improperly compacted base will show failure within one rainy season, and you’ll pay twice. Polymeric sand installation demands a completely dry surface and 24-hour cure without rain; our crews check NOAA radar before starting, a detail most homeowners miss. For anything involving base excavation, compaction equipment, or more than a few dozen square feet, the cost of rental tools and redoing the work usually exceeds our repair quote. Call (754) 254-7676 and we’ll scope it, photograph what we find, and put the number in writing before anyone lifts a paver.
