Abstract
A guttered paving block which can interlock with identical paving blocks in only one way to simply the assembly of a ground cover consisting of a square narrow waisted portion and a pair of oppositely situated extended head portions with pointed ends. The narrow waist portion makes the block easy to pick up with one hand. Dummy grooves which are parallel are provided to facilitate the manufacture of the block. Another embodiment is designed to permit a large number of patterns when assembled. It consists of a rectangular portion with a smaller square portion appended to one side of the rectangular portion.
