This project required piles on either side of a mining drill rig to support the rig during the drilling process should there be a sudden increase in drilling pressure.
We recommended piles min 3.5m deep for the required load. The customer stated a competitor recommended piles 12m deep!
3 days after the PO was received, Katana had installed (in central NSW) and undertaken uplift testing and the piles performed perfectly.
For those piling contractors that are curious, we achieved 13,000Nm at 4m.
