[origin: EP0073601A1] A concrete drainage block (10) can be end pressed to have a continuous unrestricted slot (14) communicating between the top face and a drainage channel (12). The slot (14) is lined with a metal insert (24) having downwardly divergent side walls (26) and downwardly divergent bridging portions (25) spaced along the insert and terminating short of the upper edge. Such a lined slot is easily cleaned and the edges are not susceptible to breakage.
