The construction element includes a face panel in the form of a rectangular prismatic solid. Extending rearwardly from the face panel is an embedment beam which will extend into and engage firmly with the soil mass. The embedment beam includes a sloping rearward wall to penetrate the soil mass, pan inserts and grooves to increase frictional resistance with the soil mass. The embedment beam also includes notches for interengagement with support beams in the soil mass. The embedment beam may take a variety of configurations which may be used to construct differing retaining wall arrays. | |
