Abstract
A retaining wall kit is made up of a plurality of molded blocks, some having different thicknesses and some having different lengths. Keyhole-slots may be provided at the rear face of the molded blocks, each keyhole being proportionally sized inwardly of the rear face of the block such that a retaining member fitted within the keyhole-slot projects downwardly from the one molded block to engage the rear face of an adjacent molded block so as to space the molded blocks in a regular sloped position such that the inter section of the front and top faces of each molded block is in a common plane.
