Abstract: A support post for use in the construction of a retaining wall comprises a single, rigid plate member, the bottom portion of which is pointed so that the plate member can be readily driven into the ground a distance sufficient to ensure minimal movement of the plate member. The upper portion of the plate member has at least one aperture (and preferably several pairs of apertures) in it, through which a bolt, screw or nail may be passed to hold a wall member (for example, a plank) firmly against the plate member. If the plate member is roll formed from steel sheet, it will normally have ridges or folds to improve its stiffness. A spike may extend below the plate member, and a rod may extend upwardly from the top of the plate member and be fitted with a support for a wire, cable, hose or a fence post. A support post for use at corners of a retaining wall has two half-plate members welded to a steel rod with an included angle of up to 90°.
