<p>A stackable concrete wall block is disclosed having a prism shaped body with front, rear top and bottom faces, in a stacked condition, and at least a pair of side walls for placement opposite a like block placed side by side to the wall block, whereby a lip protrudes from at least one of the sidewalls and is coplanar with the front face for spacing the body of the block from that of a like block placed adjacent thereto. As is the case with tapered blocks known in the art, this spacing allows the assembly of curved walls. However, a prism shaped block with parallel side walls and a lip is more easily manufactured than a tapered block with angled side walls, since no movable mold walls are required, when the block is made in a dry casting process. The front face and lip can have an embossed surface structure.</p> |
