auger cast piles
auger cast piles
(OP)
Gentlemen,
During installation of an ACIP, the drill rig being used broke down. The pile was drilled down to the tip elevation, and then the malfunction prevented the installation of grout. The auger was removed without grouting the hole. Is it possible to "re-drill" the open hole, place the grout, and still have an acceptable pile?
Thank you in advance for any help with this matter.

The contractor drilled out the green grout and installed new in the same places. It is likely that he did not exactly follow the old piles and probably disturbed a lot of ground. These were friction piles and the power plant sitting on top has not moved.
I'd keep a close watch on the pressure gage and make sure it is functioning.
