A precast concrete paver block for assembly with other like paver blocks to form a paved surface is described. The precast concrete paver block is a solid core block which has a first pair of flat parallel side walls and a second pair of transverse parallel side walls. One side wall of the first pair of parallel side walls has at least one block engaging projection in one or more portions only thereof and spaced between a top and bottom surface of the paver block. The opposed side wall of the pair of side walls has a slot to receive in close sliding fit the at least one block engaging projection of an adjacent one of the paver blocks for side-by-side interengagement while permitting horizontal displacement of the adjacent paver block and the block engaging projection thereof while preventing vertical displacement thereof wherein a top face of the paver blocks lie in a substantially common planar surface. A spacer is formed integral in a portion only of one of the first pair of flat parallel side walls. A further spacer is also formed integral in a portion only of one side wall of the second pair of transverse parallel side walls. The spacers form open joints about each block in portions thereof to communicate with a support bed. The paver blocks, when interconnected together, form a permeable paved surface. |
