Segmented wall systems

Abstract

A segmented wall system includes a first course extending in a first direction and comprising a first wall block and a second wall block. A rear side of the first wall block is connected to a first side of a first tail block and a rear side of the second wall block is connected to a first side of a second tail block. The segmented wall system further includes a second course stacked on the first course. The second course includes a third wall block having a rear side connected to a first side of a third tail block. The rear side of the third tail block has a width in the first direction that is equal to or greater than a width in the first direction of the rear side of the third wall block.
