A retaining wall system formed from a wire facing unit having an upstanding face section and a rearwardly extending floor section the rear end of which is provided with aligned, transversely extending, openings defined by upstanding U-shaped protuberances. The apertures in the forward portion of a geogrid can be seated over the protuberances and a connector strut interconnects the face section and floor section for providing support therebetween and for securing the geogrid to the floor section. The connector strut includes an elongated rigid rod having a curved first end that extends to a substantially right-angled bend, and a connector rod portion extends from the bend to a second end to secure the geogrid to the floor section.
