The original timber piles were driven to a dense layer at around 45 feet, but the building was experiencing continuous settlement. Borings indicted the pilings needed to go deeper to achieve refusal in a dense sand layer at 70′.
Project Summary:
- Helical Pile Type: 3.5″ Pipe Piles (.300 wall) with Underpinning Brackets
- # of Helical Piles: 58
- Location: Ocean City, NJ
- Installation Depth: 70′
- Helix Plates/Ultimate Pile Capacity: 49 Kips
- Equipment Used: Pro Dig 10K Drive head (modified) with special fabricated 12′ Boom.
- Challenge/Unique Aspect: The foundation footer was back under cantilevered porches. Alternative foundation remediation fixes required that the decks be demoed adding significant cost to the repair. Driving helicals with specially designed/modified equipment, allowed for the underpinning to take place without intrusive and costly remodeling.
