Abstract: Embodiments of prefabricated compound masonry units in lieu of build site-constructed elements are provided, as well as methods of producing the same. One embodiment comprises a first course comprising hollow blocks laid end to end with adjacent ends adhered with mortar, the hollow blocks positioned such that the first course has a hollow core; at least one channel formed in a top surface of the first course, the channel having a length; and provisional reinforcement provided along at least a portion of the length of the channel and held within the channel with a bonding material different from the mortar. The provisional reinforcement provides tensile strength to the first course for transportation and handling of the first course from a fabrication location to a build location where the first course is configured to receive permanent structural masonry reinforcement in the hollow core at the build location.
