A fireplace was added to a newly renovated home with nothing supporting the fireplace other than the hardwood floor itself. The floor began to sag and bow from the added load. An engineer determined that reinforcing the floor from the crawl space with helical piles was the only solution.
Project Summary:
- Helical Pile Type: IDEAL 1.5″ square shaft lead transitioning to 2875.203 pipe extensions
- # of Helical Piles: 7
- Location: Irmo, SC
- Installation Depth: 12′-15′
- Ultimate Pile Capacity: 25 kips
- Equipment Used: Hand-Held Drive Unit, 6K Drive, Marian Torque Indicator
- Challenge/Unique Aspect: Shackleford & Sons Contracting overcame seemingly impossible access and mobilization challenges by installing seven helical piers in a crawl space with only thirty-six to forty-eight inches of head room. Shackleford had to dig down three feet at each pile location and then dig trenches to secure the torque bar below grade while they were installing the helical piers. Once the piles were installed, floor beam brackets were attached, and hydraulic jacks lifted the floor back to level.
