An angled member includes a rod portion, for exerting a force against a leaning wall, and a cross piece, linked to one end of the rod, against which cross piece an adjustable jack acts; the other end of the rod is linked, via a connector, to a pin which is insertable within the wall or the wall's foundation, preferably the foundation, the connector passing under the foundation to connect the pin and the angle rod; roller member movably positioned intermediate the angle rod and the foundation.
One embodiment of the present invention provides for a method of placing a concrete structure in a generally horizontal position. The method includes building the concrete structure in an essentially vertical position, the concrete structure being defined by a first end. The concrete structure is pivotably supported at a support location proximate the first end while the concrete structure is in the essentially vertical position. The concrete structure is then pivoted about the support location to move the concrete structure from the essentially vertical position to the generally horizontal position.
