Helical Piles

CASE HISTORY #19980520-A
June 19, 1996
Project Edmund Toll, Inc. Scottsdale, AZ
Engineer/Architect Bingham Engineering Phoenix, AZ
Underpinning Contractor Azizona Helical-Piers Co. Phoenix, AZ

Job Description: This custom built north Scottsdale home had a problem with sinking of the retaining walls as well as settlement of the south side of the main structure itself. It was unusual for a retaining wall to settle without much rotation involved, therefore underpinning was used instead of the normal tieback.

Repair: AHPC contracted to stabilize the south side of this residence and retaining wall. 38 Helical piers, with 8” helices were installed. Some of the helices were shaved to a rock cut configuration to achieve penetration through the exceptionally rocky fill. Piers were installed to an average depth of 10ft.
