Abstract: A bracing apparatus for use with a partially or fully built wall. The wall extends upward from a base surface and has a top surface, a first face and a second face. The wall is constructed from a plurality of stacked masonry forms. The bracing apparatus includes first and second support members, a lock and a base securing mechanism. The first support member rests on the top surface of the wall and has a first brace extending downward adjacent the first face. The second support member is movably connected to the first support member and has a second brace extending downward adjacent the second face. The lock is connected to the first and second support members and is capable of securing the first and second support members in a position substantially equal to the width of at least one of the masonry forms. The ground securing mechanism is connected to at least one of the first and second support members and the base surface.
