A plastic structural panel and ground erosion barrier made therefrom in which the panel is in strip form relatively narrow compared to its length and which in general is a stretched Z-shaped cross sectional design with opposed male and female interlock edges for mating association with adjacent panel strips. The panel strip design has a 'V' configuration on opposite faces and allows optional top-to-top alignment of adjacent panels for a composite deep 'V' cross sectional shaped wall or alternate top-to-bottom turnover of adjacent panel strips to provide a thicker box ribbed cross sectional shape for the wall. The composite deep V-shaped cross section provides a greater breadth of coverage but less section modulus than the box ribbed construction. By incorporating in the design a capability of a slight flex in the panel and by forming the female interlock sections with a gap allowing alignment of adjacent panels with a small angular degree orientation, a number of wall bends or configurations can be imparted to wall constructions without need for extra components or different shaped panel strips for bends or nonconformities in alignment of the wall construction.
