Traditionally, foundations for residential homes and commercial buildings are constructed first by pouring a concrete footing. After this footing has hardened , the walls are erected normally in one of two ways: (1) by erecting forms upon the footings into which ready mix concrete is poured. When the ready mix concrete has hardened, these forms will be removed leaving the concrete walls; or by (2) by the use of masonry mortar and concrete block placed upon the footing. Thi s mortar and block will be used layer after layer until the desired height of your foundation wall is achieved. Both of these methods are labour intensive and time consuming. In this invention, foundation wall sections with tongue and groove of differenti al heights, widths and angles will be precast. A special groove will be left in the footwall when it is poured. The bottom of these wall sections will also have a tongue. Mortar is put in the groove and the wall sections are set in place and held together with asse mble clips until all the wall sections are in place and the foundation and mortar has hardened.
