Applications
Where this work fits
- Bridge and infrastructure support
- Commercial structural foundations
- Hillside and grade-sensitive foundations
- Large and small drilled shaft scopes
Specialty
Deep Foundations
Deep foundation work transfers structural loads through weak or variable near-surface soils into stronger bearing materials below. Zamborelli’s published service categories include large diameter shafts, hand-mined shafts, and drilled foundation support for projects where access, diameter, depth, and ground conditions need practical field judgment.

- Large diameter drilled shafts
- Hand-mined shafts
- Cased or open-hole drilling coordination
- Drill-only and design-build support
Context
Why it is used
- Used when shallow foundations are not a good fit for load, settlement, access, or ground conditions
- Commonly associated with bridge, transportation, commercial, and hillside foundation support
- Selection is typically driven by geotechnical conditions, structural loads, constructability, and inspection requirements
Published Support
How this capability is documented.
The original Zamborelli site lists large diameter shafts and hand-mined shafts among its foundation drilling services, supported by project photography of drilled foundation work.
