Residential Tiebacks

A home was going under remediation for the removal of an oil tank. The engineer of record wanted to have some extra support for the foundation and underpinning piers and recommended that the contractor install helical tiebacks for temporary earth retention.

Project Summary:

  • # of Helical Piles: 2
  • Location: Medford, NJ
  • Installation Depth: 15′
  • Ultimate Pile Capacity: 55 kips
  • Equipment Used: Cat 305, PENGO 12K Drive, Digital Torque Indicator
