72310-50 ABSTRACT A unique void form for use under grade beams in construction sites is disclosed. The void form has downwardly extending projections which run across the width of the void form at 90° to the longitudinal axis. The projections support the void form on the subsoil and provide additional space for the subsoil to heave as a result of frost or other temperature changes. The top of the void form has a flat surface and is adapted to support a poured concrete grade beam. The form is left in the ground after construction is complete.
