  • Patent number: 4397128
    Abstract: A reinforced masonry wall structure comprising a horizontally disposed footing having a first layer of mortar on the upper surface thereof with a first plurality of courses of masonry blocks placed one upon the other with the lowermost course being positioned on the first layer of concrete. The masonry blocks in the first plurality of courses are in intimate contact with each other since mortar is not placed therebetween. A second layer of mortar is placed on the upper portion of the uppermost course of the first plurality of courses and a second plurality of courses of masonry blocks are placed one upon the other with the lowermost course being positioned on the second layer of mortar. The masonry blocks in the second plurality of courses are also in intimate contact with each other inasmuch as mortar is not positioned therebetween. First and second layers of plaster-like material are applied to opposite sides of the masonry blocks.
