What happens if you hit rock or obstructions?

Answer: We produce a “rock tip” pile which can penetrate fractured rock, provided there is room for the point and shaft to displace the material. Sometimes we use a rock auger to “pilot drill” a pole through hard layers although this is costly and often quite difficult. The worst case scenario is where hard material or another obstruction is encountered and the pile simply spins, not progressing any further. It may be possible in certain cases to reposition the pile to avoid the obstruction or install a pair of piles spanning the obstruction
