Abstract
Wall panels are formed with horizontal edge faces. An edge portion integral with the panel projects from one of these edge faces. Another edge portion is recessed into the opposite edge face and is shaped to fit the projecting edge portion of another panel. A groove extends into each projecting and recessed edge portion to form a pair of grooves facing one another between the edge portions of successive panels. Sealing material, substantially filling the pair of grooves, completes the wall structures.
