Auger drilling does not require large tubes, which is why both the preparation and the actual process are fairly uncomplicated. The drilling auger - which is hollow from the inside - is screwed in the ground and the drilling is initiated. Upon reaching the target depth concrete is pumped through the bore hole. Ultimately, this presses the drilling auger back up. If something other than steel fiber concrete is used, the starter bars need to be vibrated into the concrete. If the drill depth needs to be altered during the drilling process, this can be adjusted at any point.
