FIELD: concrete figurate stone. SUBSTANCE: concrete stone has ramp-type working surface; cross-sectional contour of mentioned surface is provided with approximately horizontal upper part of surface, middle part of surface, approximately horizontal lower part of surface, and duct for liquid discharge. Novelty is that upper and lower sections on surface of concrete figurate stone have depressions active at least in direction of adjacent side surfaces relative to nearby apical sections of surface in direction of middle section of surface and formed by protuberance. EFFECT: improved overload protection; reduced tilting moments at improved surface force taking; improved water-tightness at joints and reliability of liquid discharge. 27 cl, 47 dwg
