Brooklyn Pulldown Pile

Limited access and mobilization issues drove the decision to use helical piles.  A successful load test on a grouted helical micropile confirmed the viability of using it in a challenging soil environment.

Project Summary:

  • Helical Pile Type: Grouted Helical Micropiles
  • # of Helical Piles: 126
  • Location: Brooklyn, NY
  • Installation Depth: 40′-60′
  • Equipment Used: Kubota Excavator and 12K Drive Head
  • Challenge/Unique Aspect: The soil profile indicated low blow count material in addition to an urban fill layer. A Grouted Helical Micropile was used to deal with buckling and lateral concerns, while also addressing access and mobilization issues.
  • Installer: Audubon Environmental & Helical Piers
