ABSTRACT:
A retaining wall for an earthen formation uses welded wire face mats having upright portions secured to one another and spanning the distance between successive lifts of the wall at the face of the formation. Elongate welded wire soil reinforcing mats with bent-up ends of a height less than the distance between successive lifts are secured to the face mats so as to extend partially over the upright portions and into the earthen formation. The bent-up ends of the soil reinforcing mats are formed with kinks which extend through the upright portions of the face mats. Rods extend through these kinks to secure the upright portions of the face mats against separation from the bent-up ends of the soil reinforcing mats. In a preferred embodiment, the face mats have a width greater than the width of the soil reinforcing mats and the soil reinforcing mats at each lift of the wall are spaced from one another and span adjacent face mats.
