Abstract (en)
A top surface 13a of a block 10 has a first groove 16 extending along a length direction, so that a certain space is formed at a horizontal joint J1 when a masonry is configured with a plurality of blocks 10 laid continuously. This configuration weakens suction or penetration of water by capillarity at the first groove 16 and, thereby preventing or minimizing intrusion of water into the inside of the first groove 16 even when water such as rainwater intrudes by capillarity at the horizontal joint J1.
