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 Carefree, including near Carefree Highlands and Mule Deer Estates.

As a third-generation, family-owned concrete company led by an active firefighter, we bring the same precision and dependability to your project that the job demands — work built to hold up under pressure.

Why Carefree Property Owners Choose 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. Carefree's boulder-strewn hillside lots call for some of the most technical grading, footing, and retaining wall work anywhere in the Valley.

Here's what makes the difference on a Carefree project:

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

Our Room Addition Concrete Slabs & Foundations Process

Site Assessment — We evaluate your existing foundation, grade, and structural tie-in points.
Excavation & Footings — Footings poured to the engineered specs for your addition's load requirements.
Slab Pour — The new slab is poured to match your existing floor elevation.
Grade & Drainage Tie-In — We regrade around the addition to keep water moving away from both structures.
Final Grade & Cleanup — Site restored and graded, ready for your framing crew.
