A method and device for stabilizing slopes that are at or near failure preferably due to a shallow, translational slides. Once a target slope has been identified, a plurality of plate piles is inserted into the entire at-risk slope to stabilize the slope. The plate piles preferably consist of a steel plate attached to an angle. The plate piles are inserted below the soil surface, with the pile extending into the bedrock, preferably in a diamond-shaped lattice pattern over the entire slope.
