66 East Street Production Install

Upon the completion of the required load test, the remaining production piles were installed to support the foundation for a new home in a coastal area.  Grouted Helical Micropiles were specified due to a high water table and low blow count soils. The Grouted Helical Micropile provided added corrosion protection and lateral support.

Project Summary:

  • Helical Pile Type: 1.75″ square shaft with grout column
  • # of Helical Piles: 30
  • Location: Brooklyn, NY
  • Installation Depth: 75′
  • Ultimate Pile Capacity: 90 Kips
  • Equipment Used: Cat 305, Digital Torque Indicator, cement mixer
  • Challenge/Unique Aspect: The reaction anchors were backed out and reused for production piles saving the homeowner some money. The contractor was able to order a cement truck with the correct Portland to water mix and pump it direct from the truck. This eliminated a man mixing cement all day. This facilitated a much quicker install (3 days) with less labor and additional savings.
