Abstract: A masonry construction module is provided which possesses versatility in the formation of various types of structures. The module has corrugations on all of its side walls which interfit complementally with the corrugations of adjacent modules in a horizontal course, thus rendering the courses of modules self-aligning and interlocked. The opposite ends of the module are respectively recessed and step projected to promote self-alignment and interlocking with modules in courses above and below. Sloping end shoulder surfaces shed water and form a barrier to water, sight and sound. The modules are designed to be laid up without mortar but can be laid up with mortar if desired and core openings can accept concrete reinforced with metal or the like to integrate structures. The corrugated side surfaces also provide ideal adhesion with stucco and the like.
