There is described a paving block (1) for use in the construction of a paved surface, which paving block has a top surface (6), a bottom surface (5) and at least one lateral surface (7) extending between the top (6) and bottom surfaces (5) and abutting in use at least part of a lateral surface of at least one adjacent paving block, wherein a portion of the lateral surface of the paving block adjacent to the top surface is tapered (8). There is also described a paving block in which at least one of the lateral surfaces (7) h as a channel (15) extending substantially from the top (6) to the bottom surfac e (5) whereby to provide a drainage path for surface water or other liquid through the channel when the paving block is laid with other such paving blocks to form a paved surface. There is further described porous paving systems for flood, rainwater and liquid spillage management incorporating su ch paving blocks.
