Belgard Home Additions & ADU Nationwide

Belgard Home Additions & ADU: The Boca Raton Owner’s Guide

We stock and install Belgard-compatible paver systems, retaining wall blocks, and hardscape components for home additions and ADU projects in Boca Raton, with typical installed pricing from $45,000 to $130,000 for full additions and $90,000 to $220,000 for detached ADUs. Most Belgard material orders arrive within 3-5 business days, and we keep common Arbel, Weston Wall, and Mega-Lafitt inventory on hand for repair work. Homeowners usually discover a Belgard component is failing when they notice settling or separation at the connection between an existing patio and a new addition slab, or when drainage channels that were cut into original Belgard paver beds begin backflowing during Boca Raton’s summer cloudbursts.

Which Belgard Models This Applies To

Belgard’s residential hardscape line breaks into three categories relevant to Boca Raton additions and ADUs: permeable pavers (Aqua Bric, Eco Dublin), retaining wall systems (Weston Wall, Diamond Pro), and standard concrete pavers (Mega-Lafitt, Arbel, Dublin Cobble). The critical compatibility gotcha in South Florida is the difference between Belgard’s standard 2-3/8 inch pavers and their 60mm commercial-grade units; additions built after 2018 often spec the thicker material for vehicular loading, and matching the bed depth requires excavating existing substrate rather than feathering in new sand.

To identify your exact Belgard unit, check the chamfer edge pattern and the spacing lug configuration on the paver underside. Mega-Lafitt has a distinctive three-piece modular pattern with false joints; Arbel carries a single irregular edge meant to read as natural stone. OEM Belgard units ship with the manufacturer’s color-matching warranty intact, which matters for sun-faded installations in Boca Raton’s UV exposure. We also source quality-equivalent units from Techo-Bloc when Belgard lead times stretch past project deadlines, and we document the substitution in writing before any work starts.

Signs Your Belgard Home Additions & ADU Is Failing

• Stepping or rocking underfoot at the addition junction. The bedding sand has washed out or compacted unevenly, usually where the original patio meets new construction. In Boca Raton’s sandy soils, this happens faster when downspouts discharge directly onto the paver bed.
• White efflorescence blooming across paver faces. Calcium hydroxide is migrating to the surface through capillary action, often triggered by the wet-dry cycling of our rainy season. It is cosmetic, not structural, but it signals moisture is moving through the joint sand instead of draining through the base.
• Retaining wall bowing or joint separation. The wall is carrying more load than designed, or the drainage aggregate behind it has clogged with our fine coastal sand. This worsens after tropical systems when hydrostatic pressure spikes.
• Joint sand washing out repeatedly. Polymeric sand has degraded or was never installed; without it, Boca Raton’s sheet-flow rainfall scours the joints and undermines interlock. Re-sanding without stabilizing is a temporary fix.
• Standing water 24 hours after rain. The base slope has reversed, or the permeable paver sub-base is clogged with sediment from nearby construction. In older Boca Raton neighborhoods near the Intracoastal, tidal groundwater can also push upward through compromised vapor barriers.

Replacement Cost & What’s Included

The range moves with bed depth, access for excavation equipment, and whether we are tying into existing Belgard color lots that have faded. Under Clause 1 of The Haven Standard, you receive a written price before any work starts, with line-item breakdown for demolition, base material, Belgard units, labor, and joint stabilization. Every Belgard installation carries our 365-Day Done Right Promise, and the documented photo record shows bed prep, drainage detail, and final compaction readings.

DIY or Call Us?

An owner can safely inspect for the symptoms above and photograph the paver pattern and any visible markings for identification. What goes wrong fast: resetting pavers without checking base slope and compaction, which guarantees the same failure in one rainy season; or pressure-washing efflorescence with acid solutions that etch the Belgard surface and void any remaining manufacturer warranty. Retaining wall repair involving stacked units over 24 inches height requires understanding live load transfer and geogrid placement, errors here can collapse a wall onto foot traffic. For Belgard work that integrates with a home addition or ADU foundation, the connection detail affects water management at the structure, and that is where we have seen DIY repairs channel termites or rot into sill plates. Call (754) 254-8065 to schedule your free estimate; we will identify the exact Belgard series, check base conditions, and give you a written price before any work starts.
