Abstract: An earth stabilization system includes a plurality of hollow jars positioned within ground to be stabilized, the jar walls formed from a concrete material or mix. The jars include a base cutter including a plurality of teeth coupled to a jar wall at or near the wall bottom, the base cutter including at least one material other than concrete, e.g., metal, diamond tip or carbide tip. The jars can be coupled to a turning tool that can cause rotation of the jar to turn or drive the jar into the soil mass or waterbed. The turning tool effects rotation of the jar and the base cutter, and the weight of the jar and the base cutter at least in part enable the jar to penetrate the ground to be stabilized. Displaced soil or other earthen material can move through a bore in the wall of the jar while the jar is being screwed into the soil in the direction of the wall bottom to the wall top. The base cutter of each jar can be welded to reinforcing material in a jar wall.
