In this method leader is attached to a crawler base machine and auger and casing is set for it and then the pile vicinity is bored and pile is removed with medium cranes. Since this method is suitable for all types of sites (large, small, pile head is in deep, etc) it is very popular and used quite frequently.
In this method three point pile pressing machine is used as base machine and pile is broken by combining earth auger and CAM auger. The torque of the auger is used for breaking the pile. It is mostly used in cases when a part of the side is damaged. Since loch screw and casing could be used separately, it has an advantage of changing the casing after breaking a part of the pile and using it for backfilling.
