Excavation Services in Village of Oak Creek, Yavapai County

excavation and site preparation in Flagstaff, AZ.

Flagstaff sits on the western edge of Yavapai County on a Supai red beds and Verde Formation alluvium soil transition, with pockets of Permian red bed sandstone in the southeastern neighborhoods near Country Club Terrace. Excavation in Flagstaff deal with variable soil across the town, so base preparation is critical. Every pour starts with 4 inches of ABC crushed stone compacted to 95 percent standard proctor density, a 6-mil vapor barrier where the foundation abuts the house foundation, and a 4-inch 3000 PSI slab with 6x6 rebar grade stakes. Joint spacing follows the American Concrete Institute recommendation of 24 to 30 times the slab thickness in feet, or approximately 8 to 10 feet between control joints for a 4-inch slab. Expansion joints separate the foundation from any fixed structure like the foundation or pool coping. Flagstaff has an active planning and zoning office at Salem Street, and permit review typically takes 5 to 10 business days for a simple residential foundation. University Highlands, Southside Flagstaff, Country Club Terrace, and Cheshire are all executive neighborhoods where larger excavation in the 400 to 1,000 square foot range are common; we routinely coordinate with landscape architects and HOA architectural review committees before pour.
