Belgard Home Additions & ADU Nationwide

Belgard Home Additions & ADU: The West Palm Beach Owner’s Guide

Belgard pavers and retaining wall systems for home additions and ADUs in West Palm Beach typically run $45,000-$130,000 installed, depending on whether you’re extending a foundation patio, building an ADU pad, or integrating a full outdoor living space into the structure. We stock Belgard-compatible materials and can usually source specific series within 24-48 hours. Most Belgard hardscape failures in West Palm Beach show up as settling, drainage backflow, or joint sand washout after heavy rain - the symptom that sends owners looking for help is often a visible dip or water pooling where the paver field meets the new addition’s slab.

Which Belgard Models This Applies To

Belgard’s hardscape lines most commonly integrated into West Palm Beach home additions and ADUs include the Cambridge Cobble, Dublin Cobble, and Lafitt Rustic Slab series for pedestrian patios, plus the Bergerac and Mega-Lafitt lines for driveways and heavier-load ADU parking pads. The retaining wall systems - Weston Wall, Celtik Wall, and Diamond Pro - frequently appear in raised foundation planters and tiered ADU site prep.

To identify your exact series, check the back of a loose paver for the molded Belgard logo and production date code, or measure the unit dimensions: Cambridge Cobble runs 6×6, 6×9, and 6×12 in a three-piece pattern; Dublin Cobble is a single 6.5×6.5 unit with a tumbled edge. The color batch matters for West Palm Beach sun exposure - older Tan/Red blends (pre-2018) fade differently than current Oyster or Sable blends, so matching requires the production run, not just the series name.

We source OEM Belgard through authorized distributors in Palm Beach County. For discontinued series, we vet aftermarket equivalents from Techo-Bloc or locally quarried travertine that matches the compressive strength (8,000 PSI minimum for vehicular load) and absorption rate (under 5% for Florida freeze-thaw, even though West Palm Beach rarely freezes - the spec matters for warranty transferability).

Signs Your Belgard Home Additions & ADU Is Failing

• Sunken or dipped paver field near the addition’s foundation. This usually means the compacted aggregate base washed out or was insufficiently compacted during original construction - common in West Palm Beach where sandy substrate drains fast but doesn’t hold edge restraint well. The fix requires lifting the affected area, regrading with DOT-approved crushed concrete base, and relaying to match the addition’s finished floor elevation.
• White efflorescence haze on paver faces. This is calcium hydroxide migrating to the surface, not a structural failure, but in West Palm Beach’s humidity it can signal trapped moisture behind a retaining wall that’s integrated with your ADU foundation. Persistent efflorescence after two rain seasons usually means the drainage aggregate behind the wall is clogged or missing.
• Joint sand completely washed out, with weeds or ant mounds. Polymeric sand breaks down under UV and pressure-washing; once gone, the interlock is gone too. In West Palm Beach, this accelerates if the paver pitch sends roof runoff directly across the field instead of to a drain. The underlying cause is often a missing or undersized channel drain at the addition’s drip line.
• Retaining wall leaning or bowing toward the addition. This is structural. The wall is either carrying surcharge load it wasn’t engineered for (common when owners later build an ADU against an original planter wall) or the geogrid reinforcement layers were omitted or shortened during installation. This requires engineered assessment - we bring a structural partner for this evaluation.
• Standing water 24 hours after rain, with a musty smell at the addition’s slab edge. The Belgard field was likely installed dead-level instead of with minimum 1.5% pitch, or the permeable paver option (Aqua-Bric or Eco-Priora) was specified but installed with standard joint sand instead of open-graded aggregate. Trapped moisture wicks into the addition’s slab and framing.

Replacement Cost & What’s Included

For Belgard hardscape work tied to home additions and ADUs in West Palm Beach, our installed pricing breaks down as follows:

What drives the range: access for mini-excavator or hand-dig, whether we need to protect the addition’s finished grade, and whether the original base was 4-inch or 6-inch compacted aggregate (West Palm Beach’s sandy soils often get specified at 6-inch, but we’ve found 4-inch shortcuts on older jobs). Every quote is a flat written price with line-item scope - under Clause 1 of the Haven Standard, the number is fixed before work starts, and no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation; Belgard’s limited lifetime warranty covers material defect.

DIY or Call Us?

There’s safe owner inspection and there’s false economy. You can check the paver pitch with a 4-foot level and verify whether joint sand is missing - that’s information worth having. You can also photograph the back of a loose paver to capture the series code before we arrive.

What goes wrong fast: lifting pavers without knowing the base depth, attempting to recompact over wet sand in West Palm Beach’s afternoon thunderstorms, or ignoring the lean on a retaining wall that carries your ADU’s surcharge load. We’ve been called to jobs where a homeowner’s well-meaning reset created a 2-inch elevation mismatch that trapped water against the addition’s stucco weep screed - the small gap that lets moisture escape - and caused $8,000 in interior drywall repair.

We’re not affiliated with Belgard Corporation; we’re independent contractors who’ve installed and repaired their systems since we started working in Palm Beach County. If you’re seeing any of the symptoms above, call (561) 475-3903 and we’ll schedule a free estimate with written pricing.
