ABSTRACT:
A retaining wall for an earthen formation relies on polymer geogrids for earth reinforcement and wire trays to provide the face of the formation. The wire trays are of L-shaped with intersecting floor and face sections. Hooked extensions formed on the face sections serve to secure the trays in superimposed relationship within the retaining wall and to hold the geogrids in place against the trays. The geogrids extend distally from the trays to provide deep reinforcement of the earthen formation.
