  • System of blocks for use in forming a free standing wall
    Patent number: 7743574
    Abstract: A system of blocks for building a free standing wall. The system includes at least one size of wall block and a generally rectangular column block. The height and depth of the column block are the same as those of the wall block and the length of the column block is twice its depth. The exposed surfaces of the blocks in the free standing wall are textured to a greater extent than the other surfaces. The blocks are used to form a wall with a rectangular column, where the wall is tied into the column to enhance the stability of the wall.
