Abstract
A cast concrete block that is cast on its side and can be separated into at least three construction blocks to be used in constructing a retaining wall system. The cast concrete block has a top face and a bottom face. The block is bounded by an elongate base side, two elongate edge sides and an elongate top side. First and second elongate splitting grooves are formed in at least one of the top face and bottom face. The splitting grooves extend between the top side and the base side. The splitting grooves are spaced inwardly from the opposite first and second edge sides. Preferably, each of the splitting grooves are paired with a corresponding secondary groove in an opposite face of the block so that each splitting groove and its corresponding secondary groove are parallel with each other and lie in a common plane that is substantially perpendicular to the broad faces of the block.
