The Difference Between Shallow and Deep Foundations in Utah

🧱 What Is a Shallow Foundation?
A shallow foundation is placed near the surface—typically 3 to 5 feet deep—and spreads the building load across a wide area.
Common shallow foundation types include:
Spread footings
Slab-on-grade
Mat foundations
These are ideal for:
Residential homes
Garages
Small commercial buildings
Sites with strong, stable surface soils
In many areas of Utah County, Salt Lake County, and Wasatch County, shallow foundations are the norm—as long as the soil is well-compacted and frost depth is respected.
⛏️ What Is a Deep Foundation?
A deep foundation transfers loads further below the surface—sometimes 10 feet or more—into more stable ground.
These are typically used when:
Surface soils are weak or expansive (like heavy clay)
The structure is multi-story or unusually heavy
The site is on a slope or unstable terrain
Deep foundation systems include:
Drilled piers
Caissons
Pile foundations
They’re more expensive but essential in parts of Utah with problematic soils, steep grades, or high load-bearing requirements (like Summit County mountain builds).
🏗️ How Do You Know Which Foundation You Need?
Here’s what determines foundation depth in Utah:
Soil composition & compaction
Frost line depth (varies by region — typically 30–36 inches)
Water table height
Building weight & footprint
Slope or hillside construction
We often work with engineers to determine load requirements and soil reports—especially on larger custom home builds or retaining wall systems.
