The supports for this steam pipe needed replacement during the middle of winter in 2009. There were two challenges. How to perform the operation in extreme cold, and how to perform the work with the steam pipe in commission.
Helical piles are well suited to cold climates. They can be installed in frozen ground, and they are always installed well below the frost line, eliminating the possibility of subsequent frost jacking. At -26 degrees Celsius we were able to install the piles successfully, and without disturbing the existing failing structures. As a result, the line remained in commission throughout the operation.
- No down-time for an essential service
- Successful installation in extreme cold
- No subsequent frost jacking
