Cambridge Pavers Home Additions & ADU Nationwide

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

Cambridge Pavers home additions and ADU projects in West Palm Beach typically run $45,000-$130,000 for a standard addition, while detached ADU construction ranges from $90,000-$220,000 installed. We source Cambridge Pavers through our vetted supplier network and can match existing Cambridge hardscape to new construction within two weeks in most cases. The call usually starts when a homeowner notices settlement cracks where the original paver patio meets a new slab, or when water is pooling against a foundation that was supposed to drain away from it.

Which Cambridge Pavers Models This Applies To

Cambridge Pavers produces several lines that show up repeatedly in West Palm Beach home additions and ADU projects. The ArmorTec and Ledgestone series are the most common in our market, with ArmorTec’s three-layer manufacturing showing up on driveways and pool decks that homeowners later want to extend into covered lanai additions. The Ledgestone XL line, at 60mm thickness, is what we typically see where an ADU patio needs to match an existing walkway.

To identify your Cambridge series, check the paver edge for the molded “CP” logo or measure the unit thickness: ArmorTec is 80mm, standard Ledgestone is 60mm, and the three-piece Ledgestone XL system runs 60mm with varying face dimensions. Color matching is the real challenge in Florida sun. Cambridge’s Sahara Chestnut and Toffee Onyx fade differently than their New England samples suggest, and we’ve learned to source from the same production lot when possible. We are an independent contractor and not affiliated with Cambridge Pavers, though we maintain direct supplier relationships that let us pull from current inventory rather than guessing at color matches from faded photos.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing

• Settlement cracks at the addition junction. The original paver base was likely compacted to 98% Proctor density, but the new construction disturbed it. We see this where ADU slabs were poured against existing Cambridge patios without proper expansion joint detail, causing the paver edge to drop 1/2 to 2 inches over two rainy seasons.
• Water pooling against the new foundation wall. Cambridge Pavers are permeable at the joints, but not the surface. When an addition roof dumps concentrated runoff onto a paver patio that wasn’t regraded, the water finds the path of least resistance, which is often the seam between old hardscape and new stem wall.
• Efflorescence blooming on new construction-facing edges. White calcium deposits mean moisture is migrating through the paver body, usually because the addition’s downspout terminates too close or the base course got saturated during framing. In West Palm Beach’s sandy soils, this means the bedding sand layer has washed out in spots.
• Chipping along the cut edge where pavers meet the slab. Cambridge’s ArmorTec face is only 3/8 inch thick; a wet saw cut exposes the softer aggregate core. If the addition contractor didn’t leave a proper control joint or expansion gap, thermal cycling pops those exposed edges within 18 months.
• Ant colonies or weed growth in the seam zone. The gap between old Cambridge pavers and new concrete is a perfect habitat. It also tells us the polymeric sand jointing was disturbed during construction and never properly resealed, which means water is getting in too.

Replacement Cost & What’s Included

The range depends on three things: whether we’re matching existing Cambridge inventory or starting fresh, whether the addition requires structural tie-in to the main roofline, and what the soil conditions show once we probe. West Palm Beach’s high water table in neighborhoods near the Intracoastal often means helical piers or stem wall waterproofing that inland estimates don’t account for. Under Clause 1 of The Haven Standard, you get the full written price before we pull a permit. That price includes the documented photo record, the Cambridge Pavers material spec sheet, and our 365-Day Done Right Promise. No change order gets signed without your initials, which is how we’ve kept 4,000-plus projects within a few percent of the original number since 2007.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can check the paver edge for the Cambridge logo, measure the thickness with a tape measure, and photograph the color from a wet and dry surface - that helps us source the right match before we meet. You can also confirm whether water is actually pooling or just slow-draining by timing it after a hard rain; standing water after 30 minutes means the base is compromised.

Where DIY goes wrong is in the structural and drainage work. Cutting into an existing Cambridge patio to tie in a new foundation affects load paths and waterproofing details that the Florida Building Code addresses specifically in Section 1807 for foundation waterproofing. We’ve been called in after homeowners excavated for an ADU slab and undermined the existing patio base, turning a $4,000 paver remediation into a $12,000 foundation repair. The high-tension elements here aren’t springs or gas lines, but the building envelope itself - once moisture gets behind that new stucco or into the addition’s wall cavity, the repair scope multiplies fast.
