Abstract
A retaining wall is formed by plastic wall blocks having fingers for extending through apertures in an end portion of a grid-like sheet of material. The remainder of the grid-like sheet of material extends rearwardly to reinforce the fill behind the retaining wall formed from a plurality of courses of the wall blocks. A curved lip at the edge of one side of each block engages a recess located on a juxtaposed side of an adjacent block. Hooks extending from a bottom member of each block engage a top member of a lower block in stacked courses of blocks. The blocks are made of a one-piece or two-piece construction. In the two piece construction, the front member is secured or securable to the remainder of the block to provide retaining walls of aesthetically different configurations.
