Homeowners in a residential neighborhood noticed their chimney was settling. They contacted Northeast Foundation and Concrete to underpinned and stabilize the chimney with concrete. However,to avoid digging up the side of the house and keeping it exposed during a concrete pour. Northeast suggested using helical piles and avoid unnecessary excavation and disturbance.
- Helical Pile Type: RS2875.203 8,10 Lead and 7 foot extensions
- # of Helical Piles: 1
- Location: Harrisburg, PA
- Installation Depth: 15′
- Ultimate Pile Capacity: 50 kips
- Equipment Used: 12K Drive Head, Marian Torque Indicator, Mini Excavator
- Challenge/Unique Aspect: The project was completed in three hours limiting exposure and liability. The footing of the chimney was exposed and cut flush with the chimney. A 50 KIP helical pile was installed, an underpinning bracket was attached to the footing and the chimney was lifted back into place.Then the area was back filled and tampered. Concrete underpinning would have taken almost two days to support this fireplace and cost more.
