A home in Sea Isle City began to settle from an addition which lacked a deep foundation. Also, the original timber piles underneath the structure were rotting. Helical piles were chosen to arrest the settlement since they can be installed in low head room situations and are hot dipped galvanized, eliminating rusting or rotting issues. New Construction helical piles were installed inside the house, for new grade beams and footings and outside for porches. Underpinning piles were installed outside and inside the house to replace rotted timber foundation piles.
Project Summary:
- Helical Pile Type: RS2875.203
- # of Helical Piles: 20
- Location: Sea Isle City, NJ
- Installation Depth: 25′ to 30′
- Ultimate Pile Capacity: 50 kips
- Equipment Used: Bobcat MT85 Loader, Prodig L5K, Digga 12als
- Challenge/Unique Aspect: Access, mobilization and restictive site conditions dictated the use of helical piers for this challenging project. Danbro installer, Coastal Marine Piling, pulled a slider in the rear of the structure to gain access for a mini walk-behind loader to install inside the home. The floor inside the house needed to be demoed and some drywall and over head lights removed. Restrictive overhead required three and five foot pile lengths inside the house. Dewatering was requied for the exterior underpinning piles due to a high water table.
