A modular earth retaining wall system comprising a plurality of similarly configured wall blocks that have lock channels and lock flanges that provide a locking mechanism for resisting leaning or toppling of the blocks. A positive retaining mechanism is also provided for attaching reinforcement fabrics to the retaining wall in between mating courses of wall blocks. This mechanism secures the reinforcement fabrics in place and permits the fabrics to extend along the entire contact area between adjacent stacked wall blocks to avoid an aggregate leaning effect. The retaining mechanism includes a retaining bar that is placed on top of the reinforcement fabric within the lock channel. The retaining bar holds the fabric against a wall of the lock channel in response to tensile loads applied to the fabric to prevent it from being pulled out of the retaining wall.
