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, inserted U-shaped, in the wire elements. The apertures in the forward portion of a geogrid, preferably an integral, uniaxially-stretched, polymer geogrid, can be seated over the protuberances and a connecting rod inserted through the openings to secure the geogrid to the wire facing unit. Strengthening struts can be engaged between cross-wires at the top of the face section of the wire facing unit and at the rear of the floor section of the wire facing unit. An aggregate, including soil or the like, can then be placed behind the face section and over the floor section of the wire facing unit and over the geogrid to form a geogrid-reinforced retaining wall section. Multiple sections may be formed side-by-side and multiple tiers can be constructed with the front faces of superior sections aligned or set back from each other to permit plantings to be placed in front of superior face sections. The connecting rod may be rigid.

A modular plastic wall block to be used for forming a retaining wall including a plurality of vertically superimposed courses, each course including a plurality of laterally juxtaposed wall blocks. Each wall block is formed of a wall block frame and an easily replaceable facing panel interconnected by a tongue and groove connection. By rotating the facing panel by 90. degree. , it can be used to overly and conceal at least a portion of the top of an uppermost course of wall blocks in the retaining wall. The wall blocks include elements for side-to-side connection enabling juxtaposed wall blocks in each course to be laterally aligned to form a straight portion of a face of a retaining wall, or to be angularly positioned to form concave or convex portions of the face of the retaining wall without the formation of gaps between adjacent wall blocks. Spacing tabs are removably carried by each wall block to enable the user to selectively adjust the spacing between the point of engagement between superimposed wall blocks and the front faces of the block below for the formation of vertical or stepped back retaining wall faces.

A method of constructing a retaining wall by connecting one or more layers of reinforcing sheet material, such as a polymeric geogrid, to the rear of one or more wall panels via slots defined in the rear walls of the panels having an angular locking section inside the panels adapted to retain U-shaped end sections of the reinforcing material carrying a connection bar that is cammed into the locking sections of the slots by a wedge.
