Abstract
A concrete forming apparatus having an inside form panel and an outside form panel spaced opposite from the inside form panel to create a gap into which plastic concrete will be placed and cured. A sheet of rigid insulation of a reduced height less than the height of the form panels is placed in the gap. A plurality of tie sleeves are pre-inserted through the insulation at regular intervals. A plurality of form ties are releasably connected to at least one of the form panels and extended through the tie sleeve to support the reduced height sheet of insulation at the desired vertical position. The tie sleeve strengthens the insulation in the area of the form tie and prevents damage to the insulation and prevents vertical movement of the insulation during placement and curing of the plastic concrete.
