A mold for manufacturing interlocking, dry-cast concrete retaining wall blocks in an upright orientation comprises a mold box comprising two side walls joined to end walls to define a mold cavity, a top face, and a substantially open bottom face. Partitions configured to define a space between adjacent blocks or a space between a block and a side of the mold box extend parallel to the side walls of the mold box substantially from the top face into the mold cavity, to form first transverse portions of the profile of the top and bottom surfaces the blocks which do not include any undercut portion that would impede removal of the mold box in a substantially vertical direction. At least one removable insert comprises insert members which, when positioned in the mold box beneath the partitions, form remaining transverse portions of the profile of the top and bottom surfaces, the remaining transverse portions including at least one undercut portion. The insert members, when in position in the mold box for casting, are substantially in lateral alignment with respective bottom surfaces of at least some of the partitions and can be inserted and retracted through openings in an end wall of the mold box.

Provided is a system and method for building retaining and freestanding stone walls, wherein wall panels are made, then transported to an installation location, and installed on site quickly and efficiently. The wall panels are made in wall frames that use joint forms to provided wall panels having sides that reliably and securely mater together. The joint forms include zig-zag like connections and a structural interlocking key, engineered to prevent vertical and lateral deformation of the assembled wall. Drainage and strengthening materials are built into the wall panels while in the wall frames. A lifting apparatus is also provided that engages a wall panel through openings formed in a rear side, and stably lifts and flips the wall panel from a facedown orientation to an upright orientation.

The present disclosure generally pertains to blocks for building landscape walls and similar structures, the molds used to make the blocks, and the methods for making the blocks. Such block can be securely coupled to another block. A block can be vertically coupled to another block by coupling the dorsal face of one block to the ventral face of another block. The block can be horizontally coupled by coupling the male side of one block to the female side of another block. A secure, exemplary landscape wall may be created by coupling the blocks both horizontally and vertically to reach a desired height, width, and shape.

A shrinkable core (100) for inserting in a mold (200) for forming a precast load bearing wall panel having a cavity, the shrinkable core (100) comprises a first wall (110) and a second wall (120), a first side element (112) and a second side element (122), and a spacing element (130). The first wall (110) and second wall (120) are spaced from each other by a first distance (d1) to define an internal region (115) in-between. The first side element (112) and the second side element (122) are arranged to close opposite edge portions of the spaced first wall (110) and second wall (120) such that fluid concrete cannot pass the opposite edge portions to get into the internal region (115), the first side element (112) and second side element (122) being spaced by a second distance (d2). The spacing element (130) is configured to vary at least one of the first distance (d1) and the second distance (d2) such that a circumference along the first and second walls (110, 120) and the first and second side elements (112, 122) shrinks monotonically with lowering said at least one distance.

Molding equipment comprising a mold having at least one cavity is disclosed. Each cavity allows the formation of a brick. A brick molding element is installed on top of each cavity to allow the formation of a mortise interlock element. The brick molding element is typically secured in place by mean of a securing mechanism. The molding equipment may be used for molding a variety of inter-engaging stackable brick element.

A mold and method for manufacturing interlocking concrete blocks. The mold comprises a mold box, comprising two side walls joined to end walls to define a mold cavity, a top face, and a substantially open bottom face. Top insert members are configured to define a space between adjacent blocks, for forming a portion of the transverse profile of the top surface of one block or a portion of the transverse profile of the bottom surface of an adjacent block, or both. A removable draw plate for closing the bottom of the mold box comprises a generally planar floor and bottom insert members configured to define a space between adjacent blocks, for forming a remaining portion of the transverse profile of the top surface of one block or a remaining portion of the transverse profile of the bottom surface of an adjacent block, or both.

A mat of revetment blocks formed with interior revetment blocks having interlocking arms and sockets. The mat has opposing sides formed with revetment toe blocks having either an arm or socket that interlocks with a socket or arm of the interior revetment blocks. The toe blocks each have an outer linear edge that forms a linear border of the mat. The toe blocks rest on respective anchor portions that extend into the ground. The mat can be used to form a roadway.

The present disclosure is directed to a new and improved family of cement block designs that have notches included therein to allow interconnectivity. In particular embodiments, the notched interconnectivity strengthens the combined block structure as compared to a structure of combined conventional blocks. Alternative embodiments replace notches with clips that create interconnectivity.

The concrete garden bed mold is plastic mold that creates concrete walls for a garden bed. An objective of the concrete garden bed mold is to provide users with a mold that easily releases the concrete block once cured within the mold. The concrete garden bed mold intends to provide users with a device that can create concrete molds with cylindrical holes to allow for a securing rebar to traverse through the concrete, securing the wall in place. To accomplish this the concrete garden bed mold has a mold cavity, a flat top surface, and tapered walls. The tapered walls ensure the created interlocking garden bed wall does not get stuck within the mold cavity as the concrete cures.
