Installer Vaspoli Builders returns to the Roxborough section of Philadelphia (after 4 years) to install grouted helical piles for the foundations of three more houses.
Project Summary:
- Helical Pile Type: 1.75″ Square Shaft helicals with a 6″ grout column
- # of Helical Piles: 207
- Location: Philadelphia, PA
- Installation Depth: 40′
- Helix Plates/Ultimate Pile Capacity: 20 Ton Ultimate
- Equipment Used: Pro-Dig 12K Drivehead
- Challenge/Unique Aspect: Back when coal was king, this underdeveloped neighborhood was a dumping ground for coal ash. The 6″ grout column surrounding the helical extensions protects the steel from the corrosive ash fill. The Grouted Helical Micropile also achieves added capacity through the rough surface of the grout column providing a less expensive pile which saved money with 207 piles over the three contiguous lots.
