An interlocking blocking system includes a plurality of interlocking blocks. Each of the interlocking blocks includes a tapered opening, a protruding bottom, and a hollow tapered inside. The tapered opening is through a top surface of the interlocking block. The protruding bottom extends beyond a bottom surface of the interlocking block. The protruding bottom includes a tapered outer surface, a thickness, and an inner tapered surface. The hollow tapered inside extends from the tapered opening on the top surface and tapers into the inner tapered surface of the protruding bottom. The tapered outer surface of the protruding bottom is shaped and sized to match and fit inside of the tapered opening at the top surface of the interlocking block. Wherein the plurality of interlocking blocks are configured to be stacked onto one another.

Provided herein are various embodiments of retaining wall blocks suitable for use interchangeably as components in battered and vertical retaining wall construction. Each includes a block body and a vertical interlock system that includes: two female-type components comprising first and second grooves each extending along a bottom side of the block body and a male-type component extending across a top side of the block body. A lateral interlock system comprises a male-type lateral interlock interface integrated with a first side of the block body in lateral alignment with a female-type lateral interlock interface integrated with a second side of the block body. Methods for constructing retaining walls using the retaining wall blocks described herein are also provided.

A block, block system and method of making a wall block. Multiple block embodiments 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 retaining wall block including a pair of curved engagement surfaces extending convexly from a rear side of the block and being symmetrical about a transverse axis are configured to engage a planar surface of a setback lip of similar overlying blocks when stacked in successive courses to form a wall structure, where the curved engagement surfaces maintain a desired setback distance successive courses for straight, convex, and concave wall structures.

A retaining wall block kit includes a block and an adjustable setback bar having a break line extending along a widthwise centerline between the front surface and the rear surface. The block has alignment knuckles protruding downwardly from a bottom surface of a front section, and has a receiver channel extending laterally across a top surface of the front section for receiving the alignment knuckles of an adjacent upper block. The setback bar can be removably located within the receiver channel, and is configured to be split along the break line. Thus, the setback bar is adjustable by being modified or omitted altogether to change the distance between the alignment knuckles and a front surface of the receiver channel and thereby allow the setback of the retaining wall to be changed as desired.

A method is for supporting a retaining wall that includes a number of wall blocks positioned to retain material against a rear side of the plurality of wall blocks. The method includes attaching the rear side of at least one of the wall blocks to at least one ground-stabilizing base body supporting the wall blocks. Kits and systems are also disclosed.

A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

A free-standing wall includes concrete base blocks adjacent to each other forming a base course; a first set of concrete wall blocks stacked on the base course and on each other to form a first wall face; and a second set of concrete wall blocks stacked on the base course and on each other to form a second wall face that faces the opposite direction from the first wall face and that has the same number of courses as the first plurality of wall blocks. Methods of constructing the wall arrangement include laying the base blocks next to each other end to end; stacking individual blocks of a first set of blocks on the base course and then on each other to form a first wall face; stacking individual blocks of the second set of blocks on the base course and then on each other to form a second wall face that faces a direction opposite of the first wall face.

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.

A kit and system for constructing structures including at least one core block, at least one fascia block that connects to the core block by mounting a shelf that extends from a face of the core block with a cut-out section of a face of the fascia block, such that the face of the core block and the face of the fascia block form a gap therein between.
