At its core, auger drilling is a process wherein a helical screw (or auger) is driven into the ground. As the auger rotates and delves into the soil, it brings the excavated materials to the surface. This process ensures that the borehole remains open and free from collapse. The spiral design of the auger blades helps in this excavation process.
