  • Patent number: 7073304
    Abstract: A block has a finished surface that provides an attractive appearance. The block is relatively large in size, allowing the quick construction of a wall, such as a retaining wall, using the block. The block includes one or more lift and alignment devices in the block that allow the block to be lifted using a suitable lifting apparatus, such as a crane, forklift, backhoe, etc. The block includes one or more recessed portions in the bottom surface of the block positioned to receive the protruding lift and alignment device of a previously-laid block underneath, thereby helping to align the block with the previously-laid block. The block includes one or more voids that extend from the top surface to the bottom surface of the block, and that align with each other when the blocks are stacked into a wall, thereby allowing fill material to be placed in the voids to strengthen the wall. The preferred embodiments also include a wall system with various different blocks that may be used to build a wall.
