Abstract
A footing form which is attached to the stem wall, which may be either field or factory fabricated. All components of which are approved by the American Wood Preservers Bureau to standard 'FDN' for direct earth contact. The footing form is filled with concrete and when said concrete hardens the form shirt is left in place, even though it adds no strength or serves any other useful purpose after the concrete hardens. Due to the treatment of the wood the form does not have to be removed from the ground, as is the case with all other untreated cellulose materials.
