Abstract: An edging unit comprises a structure having opposed top and bottom surfaces, opposed first and second side surfaces extending between the opposed top and bottom surfaces, and opposed first and second end surfaces extending between the opposed top and bottom surfaces and between the first and second side surfaces. The top surface comprises at least one pair of opposed segments. Each pair of segments includes first and second segments respectively opposing one another with respect to a center of the edging unit. The first segment defines a first upward or downward slope between the first side surface and the second side surface and the second segment defines a second upward or downward slope between the first side surface and the second side surface generally opposite in direction to the first slope.

Abstract: A connection surface that is disposed on at least a portion of a face of a structural unit comprises a first convex surface and a first concave surface arranged substantially along a first line. The shape of the first concave surface is complementary to the shape of the first convex surface. A second convex surface and a second concave surface are arranged substantially along a second line that is substantially parallel to the first line. The shape of the second concave surface is complementary to the shape of the second convex surface. The concave-convex order of the second line is reversed relative to the first line, such that the second convex surface corresponds with the first concave surface and the second concave surface corresponds with the first convex surface.
