Home › Service Areas › Gilbert › Room Addition Concrete Slabs & Foundations

A room addition slab has to match your existing home's elevation, drainage, and structural tie-in exactly — there's no room for error. Cortez Concrete handles addition foundations throughout Gilbert, including near Power Ranch and Agritopia.

We're a third-generation, family-owned concrete company built on the kind of work ethic you'd expect from a business run by a working firefighter — precise, dependable, and built to hold up under pressure.

Why Gilbert Homeowners Trust Cortez Concrete for Room Addition Concrete Slabs & Foundations

Tying a new foundation into an existing home requires matching grade, managing differential settlement between old and new concrete, and keeping drainage working correctly around the addition. Gilbert's roots as farmland mean soil conditions can vary block to block, and many properties are on larger, horse-friendly lots that call for bigger slabs and longer runs of concrete.

Here's what we get right on every job:

Permit-ready foundation work coordinated with your general contractor or architect
Engineered footings sized for your addition's structural load
Isolation joints designed to manage differential settlement between old and new concrete
Minimal disruption to existing landscaping, driveways, and hardscape during construction
Precise grade matching so the new slab ties cleanly into your existing home's elevation

Local Knowledge for Room Addition Concrete Slabs & Foundations in Gilbert

Gilbert permits through the Town of Gilbert, and its many horse-property and larger-lot neighborhoods often mean bigger slabs and longer concrete runs than a standard subdivision.

Gilbert's farmland roots mean soil can shift from sandy to clay-heavy within a single neighborhood, so we confirm base conditions before every pour.

That local knowledge is the difference between room addition work that lasts and work that fails early — and it's why Gilbert property owners keep calling Cortez Concrete.

A Family Name Arizona Has Trusted for Three Generations

Cortez Concrete isn't a franchise or a fly-by-night crew. We're a family business, now in our third generation, built on the same values our grandfather started with — showing up, doing the work right, and standing behind it. Our owner still works as an active firefighter, and that same sense of discipline, safety, and attention to detail carries over into every project we pour in Gilbert and across the Valley.

Hire Cortez Concrete and you're working directly with the family whose name is on the truck — not a call center, and not a crew you'll never see again.
