Abstract (en)
An earth confinement material (10) having vent openings (12) between adjacent cells (14) provides improved structural integrity in single layer and multilayer filled cell structures and allows venting of water and entrapped gases from certain fill materials (32). The vent openings can also be used for connecting adjacent cell sections using cable (100), nut and bolt assemblies, or the like. The vented earth confinement structures can be used with a wide variety of fill materials (32) including sand, soil, cement, asphalt, gravel, and industrial spoil materials.
