ABSTRACT:
The internally indexed building block of the invention includes a body having opposed side walls and opposed end walls which define an internal cavity therebetween and upper and lower block faces. A web is located within the block internal cavity and divides the internal cavity into a pair of vertical cells. The web terminates at one extent in a pair of vertically extending keys which extend above the block upper face and which span a dish region. The dish region is located within the block internal cavity and is depressed below the block upper face. The dish region forms a mortar cup for receiving mortar whereby an internal bond can be formed between vertical courses of the blocks.
