The invention is directed to construction implements and methods for their use in the construction of retaining walls, revetments, road ways, suspended floor spans and the like The basic element is a support sheet comprising an essentially quadrangular sheet folded about at least one longitudinal axis to produce at least one fold in the sheet. This sheet can be used to construct a load bearing surface at any angle. The support sheet can be driven into the ground with the aid of various adapters and attachments. Optionally, for additional strength, the sheet can be tied to the ground by various anchor and rod assemblies. The anchor is pivotally connected to a rod and positioned in the ground in a closed position. When appropriate tension is applied to the rod, the anchor assumes an open position and bites into the ground.
