ABSTRACT:
A footing or foundation system for a wall or like structure is provided comprising a plurality of concrete masonry ("CM") footing blocks disposed in abutting relationship along a foundation axis extending substantially parallel to the longitudinal axis of the wall to be supported on such footing blocks. The footing stretcher blocks have a lateral dimension which extends substantially perpendicular to the axis of the foundation and is substantially longer than the longitudinal dimension of such blocks which extends substantially parallel to the foundation axis. The lateral dimensions of the CM footing blocks are nominal multiples of the longitudinal dimension of such blocks; and the lateral dimension of such blocks is preferably at least four times the longitudinal dimension of such blocks. The vertical dimension of such CM footer stretcher blocks is substantially larger than its longitudinal dimension, and preferably at least twice as large; however, the vertical dimension of such blocks is significantly less than the lateral block dimensions which are preferably at least twice the vertical dimension of the blocks. The CM footing blocks have protrusions and depressions in the abutting sides thereof to provide lateral interlocking. The CM block footing or foundation system also comprises CM corner or pilaster blocks having a substantially rectangular shape and including protrusions and depressions for mating with protrusions and depressions on abutting CM footing stretcher blocks. Such CM footing stretcher and corner blocks can be made in a conventional CM casting machine with suitably modified molds and at a fast production rate.
