Unilock Home Additions & ADU Nationwide

Unilock Home Additions & ADU: The Pompano Beach Owner’s Guide

Unilock home additions and ADU construction in Pompano Beach typically runs $45,000-$130,000 for standard additions and $90,000-$220,000 for detached ADUs, with Rowan Construction Group quoting a flat written price before any work begins. We stock Unilock-compatible hardscape materials across our paver and driveway division, and we can source specific Unilock series within 24-48 hours for integrated outdoor living spaces tied to your addition. Most Pompano Beach homeowners discover their Unilock surface needs attention when settling cracks appear where the new addition meets the existing slab, or when drainage from the ADU pad washes out the joint sand in the first heavy season.

Which Unilock Models This Applies To

Unilock’s product lines break into three tiers that matter for addition and ADU work in Pompano Beach. The EnduraColor series - Beacon Hill Flagstone, Bristol Valley, Copthorne - carries a two-layer manufacturing process with a concentrated color and wear layer over a high-strength base; this matters because the 60mm thickness spec handles vehicular loads on ADU driveways where standard 50mm pavers would crack under a concrete truck during construction. The Classic series - Brussels Block, Courtstone, Il Campo - runs 50mm and works for pedestrian patios off a master suite addition, though the color-through body shows less masking if a paver chips during the heavy equipment phase of adjacent foundation work.

Identification starts with the Unilock label cast into the paver edge, visible before installation and sometimes retrievable from spare stock the original contractor left behind. The series name, color code, and batch number determine matching; we have seen Pompano Beach homeowners waste weeks trying to match “Sierra” from 2019 against current “Sierra” production only to find the iron oxide tint formula shifted. OEM Unilock carries the full warranty and color consistency guarantee; quality aftermarket equivalents from Belgard or Techo-Bloc match dimensionally but require our verification against your specific batch. We keep sample boards for Unilock’s current production runs on our truck, and we document the match with photos before ordering.

Signs Your Unilock Home Additions & ADU Is Failing

• Stepping or lippage between pavers - The bedding sand beneath has washed out or compacted unevenly, often where roof runoff from the new addition dumps onto the patio surface. In Pompano Beach’s sandy soils, this happens faster than the manufacturer spec suggests because the native substrate drains aggressively and carries fines with it.
• Efflorescence blooming as white haze - Calcium hydroxide from the concrete base or joint sand migrates to the surface through capillary action; it is cosmetic but signals moisture trapped by a vapor barrier installed incorrectly between the addition slab and the paver base. We see this most on north-facing ADU patios that never fully dry.
• Joint sand disappearing completely - Polymeric sand breaks down under UV and chlorine if the ADU serves a pool house; standard kiln-dried sand washes out where the addition gutter downspout terminates without an extension. The gap allows edge restraint failure and progressive spreading.
• Cracking concentrated at the addition tie-in - Differential settlement between the new foundation and existing structure transmits through the paver base; the crack follows the cold joint in the concrete below. This is structural, not a paver defect, and sealing the surface only traps more water.
• Color fading to gray uniformly - EnduraColor’s wear layer has eroded past its design life, accelerated by Pompano Beach’s UV index and salt air within a mile of the Intracoastal. The base color shows through, and the paver is technically sound but cosmetically spent.

Replacement Cost & What’s Included

The spread reflects four factors we itemize in every written quote: excavation and base remediation depth (often 6-8 inches of compromised material in Pompano Beach’s loose sand), the Unilock series selected, edge restraint type (plastic spike-in versus concrete curb), and whether the addition’s foundation drainage needs regrading to protect the new surface. Our price includes the documented photo record, the 365-Day Done Right Promise under The Haven Standard, and a written warranty separate from Unilock’s material warranty. No change to scope proceeds without a signed change order - Clause 1 of the Haven Standard - which is how our projects finish within a few percent of the number we gave you.

An owner can safely check three things: verify the paver series from spare stock or edge markings, photograph the failure pattern from multiple angles for documentation, and confirm whether the addition’s downspouts terminate at least four feet from the paver edge. Beyond that, the work goes wrong fast. Removing settled pavers without disturbing the adjacent surface requires a plate compactor and proper base regrading; hand-tamping leaves voids that telegraph through in six months. Polymeric sand demands completely dry conditions and precise water activation; Pompano Beach’s afternoon thunderstorms make the timing unpredictable. And any excavation within 18 inches of the addition foundation risks undermining the footing, which triggers a structural review under Florida Building Code 1804.

We are not affiliated with Unilock; we are an independent contractor that sources and installs their products to spec. If you are unsure whether the failure is the paver, the base, or the structure beneath, call (754) 714-6540 and we will schedule a free estimate with a written line-item quote.
