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.
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.

The block of claim 1, wherein the indexing and stop surfaces of an adjacent course of blocks serve to position the front surface of a block in one course of blocks in a predetermined relation with a block in an adjacent course as the indexing and stop surfaces of adjacent course of blocks are brought into registry with each other. 6. The block of claim 5, wherein the predetermined relation is coplanar. 7. The block of claim 5, wherein the predetermined relation is offset by a first predetermined distance. 8. The block of claim 5, wherein the predetermined relation is one of a plurality of predetermined distances. 9. The block of claim 1, wherein the viewable surface of the front member comprises a plurality of facets. 10. The block of claim 1, wherein the projection is generally rectangular. 11. The block of claim 1, wherein the projection is generally trapezoidal. 12. A preformed horizontally elongated block for use in a retaining wall, the preformed horizontally elongated block comprising: a front member comprising a viewable surface, a rear surface, opposing sides, opposing top and bottom surfaces, wherein the front member has a lateral extent; a rear member comprising an interior surface, an exterior surface, opposing sides, and opposing top and bottom surfaces, wherein the rear member has a lateral extent and wherein the lateral extent of the front member is greater than the lateral extent of the rear member; a web connecting the front member to the rear member, the web substantially solid with no cores and having opposing sides, and opposing top and bottom surfaces; and a single polyhedral projection extending outwardly from at least a portion of the web, the projection including an indexing surface; the web defining a recess on the opposite block top or bottom from the location of the projection, the recess extending transversely and continuously across the web, the recess defined by a stop surface that is coplanar with the back surface of the front member, wherein the recess of the horizontally elongated block is dimensioned so as to enable the indexing surface of the projection of a second block to engage the stop surface of the horizontally elongated block with no other portion of the projection of the second block contacting the horizontally elongated block. 13. The block of claim 12, wherein the projection is generally rectangular. 14. The block of claim 12, wherein the projection is generally trapezoidal. 15. A retaining wall comprising: a plurality of horizontal, preformed blocks, with each horizontal, preformed block being substantially solid with no cores and comprising a front, a rear, opposing sides, a top and a bottom, the front comprising a viewable surface and a back surface, with the plurality of horizontal, preformed blocks stacked one above the other; wherein each of the horizontal preformed blocks comprises: a single polyhedral projection extending outwardly from the block top or bottom, the projection presenting an indexing surface and presenting a first width dimension in a direction extending between the front portion and the rear portion of the block, each of the horizontal preformed blocks defining a recess on the opposite block top or bottom where the projection is located, the recess extending transversely across the block between the opposing sides, the recess comprising a stop surface that is coplanar with the rear surface of the front; with the projection and the recess extending vertically in the same direction relative to the block, and with the projection of each the horizontal preformed blocks arranged and configured to be received in the recess of the block in an adjacent course of blocks; and wherein the recess of the block presents a second width dimension in the direction extending between the front portion and the rear portion of the block, the second width dimension greater than the first width dimension so as to enable the indexing surface of the projection of a second block to engage the back surface of the front of the block with no other portion of the projection of the second block contacting the block, so as to thereby position the adjacent courses of blocks together in a predetermined relation. 16. The retaining wall of claim 15, wherein: the plurality of horizontal, preformed blocks are stacked one above the other in a columnar fashion with one block in one course positioned directly over another block in an underlying course. 17.
