Abstract
Structural panels (12) of extruded PVC and of stretched Z-shaped configuration and which can be driven into the ground include strengthening ribs (36-40) extending from the inner surfaces (34 and 35) of the opposed side sections (26 and 27). The ribs extend at a right angle to the side section bending planes (56 and 57) and at a right angle to the panel bending plane (64), thereby adding significant resistance to both compression and tension forces applied to the panel. The structural panels are driven into the earth to form a wall barrier, with the female locking element (43) being telescopically moved along the male locking element (42) of a previously installed panel. Distal strengthening rib (40) functions as a driving tongue to stabilize the position of the male locking element (42) during driving of the panel into the ground.
