ABSTRACT:
The present invention relates to mass confinement cells that may be used in retaining walls and earth retention systems that has a natural earthen appearance or other aesthetic design and is resistant to damage and wear caused by the environment. The mass confinement cells are generally light-weight and include a continuous chamber that at least partially aligns with confinement cells positioned above and below, thereby allowing the intermingling of fill material between adjacent cells. The mass confinement cells are capable of accepting and retaining any type of filling material. The filling material provides weight, stability and security to a retaining wall constructed of such mass confinement cells.
