Abstract
A method and device for properly mixing stabilizing chemicals into earthen formations. A helical blade of one or more convolutions is attached to a hollow torque tube and rotated down into the soil. As the device is rotated through the soil to be stabilized, chemicals are pumped down the torque tube, out the device, and then mixed into a soil column by the rotating action of the device.
