Abstract
A ground stabilization grid which includes a series of polygonal shaped cells having “x” sides. The cells are formed by polymer walls having a wall height of between about 1″ and about 6″. Each cell shares a common wall section with at least two adjacent cells; and a majority of cells within the grid includes at least two reinforcing ribs extending across the cell to engage opposing walls of the cell. The reinforcing ribs are characterized by (i) engaging the cell walls between about 25% and about 75% of the wall height, and (ii) extending between different opposing walls of the cell.
Claims20
A ground stabilization grid comprising:
- (a) a plurality of polygonal shaped cells having “x” sides, the cells formed by walls having a wall height of at least about 1″;
- (b) each cell sharing a common wall section with at least two adjacent cells;
- (c) a majority of cells within the grid including at least one reinforcing rib extending across the cell to engage opposing walls of the cell, the reinforcing rib (i) attaching to the cell walls between about 25% and about 75% of the wall height, and (ii) extending between different opposing walls of the cell.
A method of producing a ground stabilized pad comprising the steps of:
- (a) positioning on a surface a stabilization grid comprising:
- (i) a plurality of closed cells formed by polymer walls having a wall height, each cell sharing a common wall section with at least two adjacent cells;
- (ii) substantially each cell including at least one reinforcing rib extending across the cell to engage opposing walls of the cell, the reinforcing ribs (i) engaging the cell walls between about 25% and about 75% of the wall height, and (ii) not engaging the cell walls at less than 25% or more than 75% of the wall height;
- (b) filling the cells with a load bearing material.
An artificial turf system comprising:
- (a) a surface stabilization grid comprising:
- (i) a plurality of closed cells having a wall height, each cell sharing a common wall section with at least two adjacent cells;
- (ii) substantially each cell including at least one reinforcing rib extending across the cell to attach to opposing walls of the cell;
- (b) a load bearing material filling substantially all the cells of the grid;
- (c) a layer of drainage fabric positioned over the stabilization grid;
- (d) an artificial turf positioned over the layer of drainage fabric.
