  • Patent number: 7096635
    Abstract: A retaining wall with a series of differently sized, pre-formed blocks. Each block includes a projection and a recess, with the projection and recess arranged and configured so that each projection effectively engages a recess in an adjacent course to connect and align adjacent courses in registry. Retaining walls made of horizontal blocks may be stacked in columnar fashion or running bond fashion. The location of the indexing surface on a projection relative to the viewable surface of the block may be varied to enable adjacent courses to be coplanar or tiered in a variety of predetermined offset distances.

  • Patent number: 7090438
    Abstract: A block for use in constructing a multiple course retaining wall. The block has a substantially planar top surface, a front surface, wherein said front surface is of a substantially curvilinear shape, a rear surface, opposed side surfaces, and a bottom surface. The bottom surface has a predetermined area and a non-planar portion, with the non-planar portion comprising a continuous area making up at least one-quarter of the bottom surface and creating a cavity between the bottom surface of the block and a top surface of a lower course of blocks when the block is placed on the top surface of the lower course of blocks. The cavity allows dirt and other foreign matter to exist between successive courses of blocks without creating instability between the block and the lower course of blocks.

  • Patent number: 6910833
    Abstract: A block for use in constructing a retaining wall. The block has a bottom with a non-planar portion that forms a gap between the block and the top surface of a lower course of similar blocks when the block is placed thereon. This gap allows the block to rest on the lower course of blocks in a stable, level manner by providing a space that can accommodate small amounts of intrusive material such as rubble, dirt, or miscellaneous debris which would otherwise interfere with the stacking of the blocks. The block's bottom may also include a plurality of grooves that provide additional clearance in the gap for larger bits of intrusive material such as pebbles or small stones. Preferably, the grooves have angled walls which act to funnel the larger bits of intrusive material into an area of adequate clearance when the block is being placed on a lower course of similar blocks.

  • Patent number: 6682269
    Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon is herein disclosed. The non-planar portion permits the block to rest on a lower course of blocks and provides a space where small amounts of rubble and dirt may exist without interfering with the stacking of the blocks. The non-planar portion of the block reduces the unit weight of the block without significantly affecting the structural integrity of the block. The block's bottom surface may further comprise a plurality of grooves and a gutter constructed and arranged with respect to the non-planar portion so as to define a bearing surface therebetween.

  • Patent number: 6651401
    Abstract: A retaining wall comprising a series of differently sized, pre-formed horizontal and vertical blocks. Each block includes a projection and a recess, with the projection and recess arranged and configured so that each projection effectively engages a recess in an adjacent course to operatively connect adjacent courses together. The horizontal, blocks are formed in incremental thicknesses and may be stacked in various combinations equivalent to the height of the vertical, blocks. The location of the abutment member relative to the block may be varied to enable adjacent courses to be coplanar or tiered in a variety of predetermined offset distances.

  • Patent number: 6592301
    Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon. Preferably, the block's bottom surface further comprises a plurality of grooves. It is envisioned that these grooves be “V” shaped, thereby having angled walls which act to funnel the larger stones into an area of adequate clearance when the block is being placed on a lower course of similar blocks.

  • Publication number: 20020054790
    Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon. The gap allows the block to rest on the lower course of blocks in a stable, level manner by providing a space where small amounts of rubble and dirt may exist without interfering with the stacking of the blocks. The non-planar, preferably concave, portion is also advantageous in that it reduces the unit weight of the block without significantly affecting the structural integrity of the block. Preferably, the block's bottom surface also has a plurality of grooves which further reduce the weight of the block and provide areas of increased relief for larger stones. The grooves may be “V” shaped, and have angled walls for directing larger stones into the areas of increased relief when the block is being placed on a lower course of similar blocks.

  • Patent number: 6168353
    Abstract: A retaining wall made up of a plurality of blocks shaped to prevent the escape of material used to fill the cavities of the wall while allowing dissipation of pressures exerted on the wall by the retained earth and a method of constructing the wall taking advantage of the continuous, uninterrupted vertical cavities formed by the unique shape of the blocks. The shape of the blocks comprises a front portion interconnected to a rear portion which has ears on opposite sides which cooperate on adjacent blocks to create a tortuous path into a space created between two adjacent blocks. In a preferred embodiment the rear portion further comprises a cavity which, when pyramidally placed on top of two adjacent blocks, forms a continuous, uninterrupted vertical column which significantly increases the weight and strength of the wall when filled with a particulate filling material.

  • Patent number: 5653558
    Abstract: A retaining wall block is provided which comprises a forward, face portion and a tail portion spaced rearwardly of said face portion and extending generally parallel thereto, said face portion and said tail portion being connected by a central web. A downwardly depending abutment member is formed on the bottom of said face portion to serve as a spacing mechanism for offsetting successive courses of block, thereby imparting a uniform backslope to the retaining wall. The block is designed in such a fashion that portions of the spacing mechanism may be easily removed or modified so as to permit different angles of backslope.
