Foundation prep scope
New Construction Foundations
Site layout, excavation, sub-base, drainage — ready for concrete.
Addition Foundations
Tie-in excavation to existing structures with minimal disruption.
Basement Excavation
Walk-out and full basement digs, shoring as needed.

Excavation to convert crawl to basement or slab on grade.
Drainage Retrofit
Existing-home French drains and waterproofing.
What you get with A to Z foundation prep
Same-Company Concrete
We excavate and we pour. The handoff is internal — no inter-trade blame games.
Engineering Coordinated
We work from stamped drawings and confirm compliance before pour day.
Documented Compaction
Density test reports on file for any inspection or future buyer.
Water Managed
Drainage and waterproofing are part of the foundation spec, not an afterthought.
Frequently Asked
Q.Do you handle both excavation and concrete?
Yes — that's a major advantage of hiring A to Z. The excavator and the concrete crew are the same company, so there's no finger-pointing if something doesn't line up.
Q.How deep do foundation footings need to be?
Iron County frost line is generally 30 inches; footings typically extend to 36 inches below grade for code compliance. Heated structures and basement walls have their own requirements that we'll confirm against your plans.
Q.What about drainage around the foundation?
We install a perimeter footing drain (4-inch perforated pipe in washed rock, wrapped in filter fabric) connected to daylight or a dry well. Foundation waterproofing membrane goes on the exterior of stem walls before backfill.
Q.Can you handle expansive clay soils?
Yes. Cedar City and Iron County have areas of expansive clay. The standard solutions are over-excavation with select fill, structural reinforcement, or pier-and-beam foundations — we work with your engineer to spec the right approach.
