A retaining wall, supported by a footer, foundation or conventional retaining wall, includes a plurality of post-tensioning rods anchored in the underlying support and extending through the cells of blocks forming the courses of the retaining wall. An elongated apertured plate or a plurality of individual plates rest upon the next to last course to penetrably receive the threaded ends of each of the rods. Nuts engage the threaded ends of the rods to draw the rods to the plate and place them in tension. The top course rests upon the plate or plates and may be constructed as a bond beam. The rods extending from the support may be located adjacent the said side of the retaining wall and bent away therefrom to penetrate the plate or plates at the lateral midpoint of the plate or plates and thereafter extend essentially vertically upwardly. To add an extended wall supported on the bond beam, couplings may be threadedly engaged with the rod ends. Further rods threadedly engage the couplings and extend upwardly. The courses of the extended wall are penetrably engaged with the further rods. An apertured plate or plates rest upon a course to receive the upper threaded ends of the further rods. Nuts engaging the upper ends of the further rods draw the further rods toward the plate or plates to place the further rods in tension. Additional courses or cap blocks may be placed upon the course supporting the plate or plates in the extended wall.
