Cambridge Pavers Home Additions & ADU in Las Vegas, NV

Cambridge Pavers Home Additions & ADU: The Las Vegas Owner’s Guide

Cambridge Pavers-compatible home additions and ADU construction in Las Vegas typically runs $45,000-$130,000 for additions and $90,000-$220,000 for detached ADUs, with most feasibility assessments completed same-week and construction starts within 30-45 days of permit approval. We stock Cambridge Pavers inventory for integrated hardscape elements, patio foundations, and driveway tie-ins that connect your addition to the existing property. Most Las Vegas homeowners discover their Cambridge Pavers surfaces need attention when settling cracks appear where the new structure meets old concrete, or when drainage from the addition channels water across pavers that weren’t engineered for that load.

Which Cambridge Pavers Models This Applies To

Cambridge Pavers produces several lines relevant to home additions and ADU projects in Las Vegas: the ArmorTec series for driveways and heavy-load areas, the Renaissance collection for patios and walkways, and the Sherwood line for permeable applications where drainage compliance matters. The critical compatibility gotcha is the thickness differential: ArmorTec runs 80mm, while Renaissance and Sherwood are 60mm. Mixing these in a transition zone between your existing hardscape and new addition creates a trip hazard and voids the Cambridge warranty on the thinner product.

To identify your installed Cambridge product, check the spacer bars on the paver edge: ArmorTec has a double-beveled side with “CP-AT” stamped on the spacer nub; Renaissance carries a single chamfer with no stamp; Sherwood permeable pavers have visible vertical drainage channels on all four sides. If your addition or ADU project requires matching existing Cambridge Pavers that are 10-15 years old, color drift is significant in Las Vegas UV exposure. The “Sahara” line from 2012-2016 runs notably lighter than current production. We source from Cambridge’s Arizona distribution hub for closest-match lots, and we always pull from the same production batch for contiguous surfaces.

Signs Your Cambridge Pavers Home Additions & ADU Is Failing

• Step cracking along the addition foundation line. This happens when the Cambridge base wasn’t compacted to 98% standard Proctor density before the addition slab was poured. Las Vegas caliche soil expands and contracts with seasonal moisture changes, and a 4-inch sand setting bed without proper aggregate base lets the pavers telegraph every shift. We see this most in Summerlin and Centennial Hills where cut-and-fill grading disturbed native soil profiles.
• White efflorescence bloom that returns after cleaning. Cambridge’s concrete composition contains soluble salts that migrate with water vapor. In ADU projects where irrigation systems were rerouted or downspouts discharge near the hardscape, continuous moisture wicking pulls salts to the surface. It’s not just cosmetic; it signals water is moving through the joint sand and undermining the bedding layer.
• Loose pavers that rock underfoot at the garage-to-ADU walkway. The polymeric sand jointing failed, usually because it was installed when surface temperature exceeded 90°F, which is most days in Las Vegas from May through September. Heat accelerates premature curing before the sand settles into full joint depth, leaving voids that let water penetrate and erode the base.
• Chipped corners on ArmorTec pavers at the driveway addition junction. ArmorTec’s surface compression is excellent, but the chamfered edge is vulnerable to point-loading from construction equipment during the addition build. If your contractor ran a mini-excavator or material delivery over installed pavers without protective plywood, the damage often doesn’t appear until 6-12 months of thermal cycling completes the fracture.
• Pooling water that wasn’t there before the addition. Cambridge permeable pavers (Sherwood line) clog with fine desert dust over 3-5 years, but accelerated clogging after an addition project usually means construction debris was washed into the joints. In Las Vegas, where we get intense but infrequent rain, that first storm after construction reveals the problem fast.

Replacement Cost & What’s Included

What drives the range: square footage, existing demolition requirements, and whether your Cambridge Pavers need full removal or selective replacement. In Las Vegas, we factor in Caliche soil conditions that often require deeper excavation and imported base material. Our quotes include permits, base preparation, Cambridge product, installation, and polymeric sand jointing. The 730-Day Done Right Promise covers all workmanship. Upfront pricing, no surprises - the number you see is the number you pay. We also offer 0% financing for 18 months and $1,000 off projects over $10,000.

DIY or Call Us?

Here’s where an owner can safely assess: measure the affected area, photograph the paver stamps for identification, and check for obvious drainage blockages like piled landscape debris. What you shouldn’t attempt: lifting settled pavers to regrade the base, cutting ArmorTec with anything less than a wet saw with diamond blade, or re-installing without proper plate compactor access. The base preparation is where DIY goes wrong in Las Vegas - our caliche soil doesn’t drain like the East Coast substrates Cambridge’s general guidelines assume. A 6-inch aggregate base in New Jersey might be 10 inches here. And if your addition or ADU involves any tie-in to the foundation drainage, improper grading channels water toward the structure, not away. That’s not a weekend fix; that’s a foundation repair waiting to happen. Call (855) 951-4361 and we’ll assess it properly - estimates are free.
