A reinforced retaining wall is provided comprised of precast, concrete block facing elements connected by suitable connectors to reinforcing members which extend from the facing elements into the adjacent reinforced soil to form a mechanically stabilized earthen wall construction. The connectors which affix the reinforcing members at their connecting ends to the facing elements comprise concrete poured into a part or all of certain of the void spaces within selective facing blocks, which concrete may or may not be reinforced and which concrete, when dry and cured, envelops and secures the connecting ends of the reinforcement members to their corresponding blocks and forms anchors thereat. In addition, wall constructions are provided having reinforcement members with differing reinforcement characteristics placed at different elevations of a wall, as desired, to accommodate specific design requirements, such as, for example, soil nails, metallic grids and geotextiles, all of which are employed as reinforcements in a single wall construction.
