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.

Abstract: A building unit including upper and lower surfaces, and a plurality of side surfaces extending between the upper and lower surfaces defining a generally trapezoidal shape in plan view. The unit includes a first pair of the side surfaces, located on opposite sides of the unit and extending non-linearly and generally obliquely with respect to each other in plan view, where each side surface of the first pair has a midpoint bisecting it into two portions. The portions on each side of the midpoint are a 180° rotational image of the other portion about the midpoint. One side surface of the first pair is longer than the other, and the longer side surface includes a midsection of the same length and configuration as the other, shorter side surface. Each of the shorter and longer side surfaces interlocks with either the shorter or longer side surface of another like building unit.

Abstract: A block, block system and method of making a wall block. A block with multiple embodiments of a visually exposed surface having three dimensional shaped areas and three dimensional angular valleys or joints that can be used to construct a patio, wall, fence or the like; the multiple embodiments creating a more random and natural appearance. A mold box having a moveable liner and a stripper shoe that impart three dimensional shaped areas and three dimensional angular valleys or joints onto an exposed surface of a block. The moveable liner and stripper shoe also impart a parting line onto the exposed surface of the block.

Abstract: A three dimensional structural unit includes at least one face having a rotational tessellation. The at least one face has at least two irregular sides extending there from. At least one of the sides has connectors adapted to align adjacent units.

Abstract: A wall block comprises an upper surface and an opposed lower surface. A front face and an opposed back face, and a first side face and an opposed second side face, are disposed between the upper surface and the lower surface. The first side face and the second side face generally extend from the front face to the back face. The block includes one or more features that define a horizontal alignment direction. The front face extends from the first side face to the second side face generally along a direction that is slanted with respect to the horizontal alignment direction.

Abstract: A surface covering unit includes at least one face comprised of at least one primary rotational tessellation element. The rotational tessellation element includes at least two pairs of sides, and the sides in each pair of sides have the same length and are images of one another. The sides of a first pair of sides extend from a first vertex and are rotationally spaced from each other, and the sides of a second pair of sides extend from a second vertex and are rotationally spaced from each other. The sides of the first and second pairs of sides have two or more straight line segments or complex curves, and are not a single straight line or a single curve. One pair of sides has a length different from the other pair of sides. The surface covering has a natural appearance such that a repeating pattern is not readily apparent.

Abstract: A wall block comprises an upper surface and an opposed lower surface. A front face and an opposed back face, and a first side face and an opposed second side face, are disposed between the upper surface and the lower surface. The first side face and the second side face generally extend from the front face to the back face. The block includes one or more features that define a horizontal alignment direction. The front face extends from the first side face to the second side face generally along a direction that is slanted with respect to the horizontal alignment direction.

Abstract: An irregular trapezoidal structural unit configured to be arranged with other like units in courses to form a structure comprises opposing upper and lower surfaces, opposing irregular front and rear faces, and irregular opposed side faces. The side faces each include a general S-shape mating section that are translated images of each other such that each side of the unit will mate with either side face of another like unit. The front and rear faces optionally include S-shaped mating sections that are translated images of each other. Structures are formed in courses by arranging units side to side along a line to form at least a first course, wherein adjacent side faces mate and interlock. Optionally, a second course is disposed laterally adjacent the first course wherein adjacent front and rear faces mate and interlock. Additional courses can be added on top of the other courses forming wall structures.

Abstract: An improved landscape edging system is described. The landscape edging system includes an edge piece having a first end and a second end, the edge piece having a substantially vertical wall and a base, the base comprising a first footing at the first end and a second footing at the second end, the first footing being spaced apart from the second footing, the first and second footings having a stake opening, the first end having an inwardly stepped section on the wall and a stepped up section on the base. A method of installing the landscape edging system is also described.

Abstract: A block suitable for use in paving, edging or wall applications comprises a lower portion having parallel, substantially vertical side faces that are spaced apart by a first width, and an upper portion having parallel, substantially vertical side faces that are spaced apart by a second width. The second width is smaller than the first width of the lower portion, and the side faces of the upper portion are angled relative to the side faces of the lower portion. The block further comprises a transition portion between the upper and lower portions, having at least one slanted side extending between one or more sides of the lower portion and one or more sides, respectively, of the upper portion.

Abstract: A building unit has a substantially planar base having an outer periphery including multiple mating sides. Each mating side has at least one “S”-connection, which includes at least one outwardly extending male mating section and at least one inwardly extending adjacent female section. On the base, there are multiple cobbles or raised regions separated by false joints. A first portion of the raised regions are positioned on the male mating sections, respectively and extend to positions proximate to the outer periphery of the base. A second portion of the raised regions are positioned adjacent the female mating sections, respectively and are set back from the outer periphery. Each side of one unit can mate with any side of another like unit. The arrangement results in a surface covering that lacks a discernible pattern.
