Abstract
A stackable grid material for soil confinement is disclosed. The grid material comprises repeating pattern of cell structures with thin cell walls in between cells and open cell tops and bottoms. The cell wall material of the grid is notched such that the top edges of the cell wall material on the perimeter of a lower layer of grid material overlaps with the bottom edges of cell wall material on the perimeter of an upper layer of grid material. The internal cell walls are able to rest on top one another in spite of the overlap at the perimeter walls due to the positioning and shape of the notches.
