ABSTRACT:
The present invention relates to a retaining wall block that is resistant to damage and wear caused by the environment and includes a chamber, which allows the flow of fill material to adjacent blocks below and above. The deterioration resistant block is generally a hollowed frame or shell of a deterioration resistant material that is light-weight and is configured to interlock with adjacent blocks, thereby forming a continuous chamber 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 blocks.
