Foundations engineered for Arizona soil — and finished on schedule.
Footings, stem walls, monolithic slabs, and full site excavation for residential and commercial builds across Maricopa County.
Why we're one of the best foundations & excavation companies in Tempe
- Excavation, prep, and concrete under one roof — no scheduling gaps between trades.
- We work with your structural engineer (or coordinate one) to make sure everything matches the plans.
- Decades of experience pouring on Maricopa County soils — caliche, expansive clay, you name it.
- Inspection-ready every time: rebar tied to spec, vapor barriers properly lapped, footings dimensioned right.
- Honest conversations about value-engineering when an over-spec'd foundation is wasting your budget.
Affordable foundations & excavation options near you
The cheapest foundation bid is rarely the cheapest foundation. We've torn out enough cracked slabs from under-prep'd jobs to know that proper compaction, rebar, and vapor barrier are not where you save money. What we can do is right-size the spec — match thickness and PSI to actual loads, optimize rebar grids, and avoid premium add-ons your project doesn't need.
How much does foundations & excavation cost?
Typical range: Residential slab foundations: $5–$10 per sq ft. Stem-wall: $7–$14 per sq ft. Commercial footings & mats: engineered per job.
Final price depends on:
- Soil type and required compaction
- Engineered footing depth and width
- Rebar grade, size, and grid spacing
- Vapor barrier and termite treatment
- Excavation volume and haul-off
- Concrete PSI (3,000 vs 4,000+ psi)
- Site access for trucks and pumps
- Inspections required
What to look for when hiring
- Confirm Arizona contractor license and active insurance.
- Make sure they handle excavation in-house or coordinate it tightly.
- Ask how they handle expansive or caliche-heavy soils.
- Get the rebar schedule, PSI, and vapor barrier details in writing.
- Confirm who pulls the permit and schedules inspections.
- Ask for recent foundation references in your city.
Common problems we solve
Who should I hire to pour my foundation?
Hire a licensed contractor that handles both excavation and concrete in-house, has Arizona soil experience, and gives a written rebar/PSI spec — like EL Construction.
Cheapest vs best foundation contractor?
Cheapest bids usually skip prep — compaction, vapor barrier, rebar grade. Best contractors quote everything in writing and stand behind it with a warranty.
Who's fastest? When can you excavate?
Same-week site visits, with most foundations starting within 2–4 weeks once permits and engineering are stamped.
Most reliable foundation contractor in Tempe?
Reliability is on-spec rebar, on-time pours, and inspections passed first try. That's how we run every foundation.
