Abstract: A hardscaping unit includes a first block fixedly attached to a second block. The method of assembling the hardscaping unit includes the steps of forming a first block from a first material, placing a second material into a mold, contacting a surface of the first block with the second material that is in the mold, maintaining contact of the surface of the first block with the second material while transitioning the second material from a first state to a second state, the second state being more solid than the first state, and when in the second state the second material forms a second block that is fixedly attached to the first block.

Abstract: A cast block for use in a wall is provided. The block includes: a body including a top surface and an opposed bottom surface; and a face portion extending frontwardly from the body portion, the face portion including a front surface, an upper tapered surface, and a lower tapered surface, the upper tapered surface disposed between the top surface and the front surface and the lower tapered surface disposed between the bottom surface and the front surface; wherein the front surface, the upper tapered surface, and the lower tapered surface are each patterned. Also provided is a wall formed of rows of cast blocks. Also provided is a method of forming masonry blocks for use in structural retaining walls.

Abstract: A block assembly and wall system wherein a block of masonry, or other material is provided with a vertical through opening having an enlarged and offset lower portion and a smaller upper portion. An interlock element has an enlarged offset upper portion and a smaller lower portion to provide for insertion of the latter into the upper portion of a block opening. The upper portion of the element is entered into the lower portion of an adjacent block placed atop the first block. The blocks are thus secured in position horizontally and, alternatively, the blocks may be secured vertically or in a "battered" wall construction. That is, with the connecting elements in a first attitude, a conventional vertical wall is provided whereas a 180.degree. (one hundred eighty degrees) rotation of the elements about their vertical axis results in a "battered" wall.
