Cambridge Pavers Home Additions & ADU Nationwide

Cambridge Pavers Home Additions & ADU: The Fort Lauderdale Owner’s Guide

Cambridge Pavers home additions and ADU projects in Fort Lauderdale typically run $45,000-$130,000 for standard additions and $90,000-$220,000 for detached ADUs, with most Cambridge Pavers-compatible hardscape integration quoted within 48 hours. We stock the full Cambridge Pavers catalog - ArmorTec, Ledgestone, and Renaissance series - and can match existing installations for seamless transitions between original patios and new construction. Most Cambridge Pavers material orders arrive within 3-5 business days to our Fort Lauderdale warehouse.

Owners usually discover the hardscape connection point is failing when they see settling cracks where the new addition meets the original paver patio, or when water pools against the foundation after a rain - a sign the permeable base detail was skipped or compacted improperly during the original install.

Which Cambridge Pavers Models This Applies To

Cambridge Pavers organizes its residential line into three series that matter for Fort Lauderdale additions and ADUs. ArmorTec is the through-color, high-density line with the baked-on surface layer - it holds up to salt air and pool chemicals better than standard concrete pavers, which matters when your ADU sits near a canal or the Intracoastal. Ledgestone mimics natural stone in three thicknesses: 60mm for pedestrian areas, 80mm for driveways, and the 30mm overlay system used when you’re tying into an existing slab without full demo. Renaissance is the tumbled, antique-faced line - popular in Coral Ridge and Rio Vista where the aesthetic leans older Florida.

To identify what you have, flip a loose paver or check the edge of a cut. Cambridge stamps the series name and production date on the underside. The critical spec is thickness: a 60mm paver on a 6-inch base won’t plane out with an 80mm paver on 4 inches, and we’ve seen that exact mismatch where a Fort Lauderdale homeowner’s previous contractor matched color but not elevation. The result was a trip hazard and reverse slope toward the house.

We source Cambridge Pavers direct from the distributor in Medley - not gray-market seconds. For discontinued colors, we’ll pull the original spec sheet and cross-reference to current production, or quote a compatible alternative from Belgard or Techo-Bloc with the color variance noted in writing.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing

• Step cracking along the addition joint. This happens when the new foundation settles at a different rate than the original paver base, usually because the contractor used different fill material or skipped the geo-grid stabilization that Cambridge recommends for load-bearing transitions. The crack follows the cold joint exactly.
• Standing water 24 hours after rain. Cambridge’s permeable pavers are rated for 8-10 inches per hour infiltration, but that assumes a properly graded open-graded stone base. In Fort Lauderdale’s flat terrain with a high water table, we’ve found base depths shallower than 10 inches fail first - the water has nowhere to go.
• Pavers rocking underfoot or sounding hollow. The bedding layer has washed out, typically where downspouts discharge onto the hardscape or where irrigation heads overspray. Cambridge specifies ASTM C33 concrete sand; if a crew used mason sand or limestone screenings, it compacts too tight and doesn’t drain.
• White efflorescence blooming across the surface. This is calcium hydroxide migrating through the paver body - harmless structurally, but it signals moisture trapped in the base. In Fort Lauderdale’s humidity, efflorescence that returns after cleaning almost always means a compromised vapor barrier or no barrier at all beneath the base.
• Chipped or spalling edges on ArmorTec pavers. The through-body color means the damage shows, but more importantly it indicates impact or freeze-thaw stress at the edge restraint. Cambridge’s snap-edge aluminum restraint is rated for the load; plastic edging degrades in UV and lets the field spread.

Replacement Cost & What’s Included

The spread on additions and ADUs comes down to three things: foundation type (stem wall vs. slab-on-grade), utility extension distance, and whether we’re matching existing Cambridge Pavers that are still in production. A 400-square-foot addition with direct patio access and no plumbing runs toward the lower end. A 750-square-foot detached ADU with full kitchen, bath, and a new Cambridge Ledgestone driveway connection runs toward the upper.

Every quote is line-item: paver material by series and square footage, base depth and compaction spec, edge restraint type, and permit fees itemized separately. Under Clause 1 of the Haven Standard, that written price is fixed - no change proceeds without a signed change order, which is how we’ve kept 4,000-plus projects within a few percent of the original number since 2007. The 365-Day Done Right Promise covers the installation; Cambridge’s own limited warranty covers material defects.

DIY or Call Us?

There’s a short list an owner can safely check. Verify your downspouts discharge past the paver edge, not onto it. Confirm irrigation heads aren’t spraying the hardscape. Look for the Cambridge stamp on a loose paver to identify your series. These are observations, not repairs.

Where DIY goes wrong is the base. Removing even a small section of failed pavers exposes a layered system - compacted subgrade, geo-grid, open-graded base, bedding sand - each with a specific depth and compaction percentage. In Fort Lauderdale’s sandy soils, over-excavation destabilizes the surrounding field; under-excavation leaves the organic layer that caused the failure in the first place. And the plate compactor rental won’t help if you don’t know the test-strip procedure to verify 98% modified Proctor density.

We’ve also seen homeowners crack adjacent foundation work with improper saw cutting, or bridge the new addition’s dampproofing with a paver bed that traps moisture. The repair then becomes structural, not cosmetic. Measure twice, write it down, then say it once - that’s how we scope it, and it’s why we recommend a documented site visit before any material gets ordered. Call (754) 254-7676 to schedule yours; estimates are free, and we bring the spec sheets.
