The present invention relates to a self-supporting, prefabricated, folding form structure or mechanism to be used in the construction industry. It is based on various types of geometries, providing enhanced strength and stability for the concrete and other building material casting process. The object of this invention is a foldable, prefabricated, self-supporting form and does not require a structure. It is configured in a variety of geometric shapes and is based on structural elements that have internal casting chambers or ducts interconnected between each other through perforated holes. This is done by means of internal assembly channels or cavities forming casting chambers. The casting chambers are interconnected with each other, through holes drilled in the structural elements. This way the form features an assembly between its walls through cracks or assembly cuts, creating an architecture of superior engineering that provides higher resistance and stability.

A method for constructing a retaining wall using an adjustable single stage panel system has the steps of placing a wall panel adjacent a fill location, then placing a facing wedge adjacent the wall panel, and installing fabric sheet. Next, adding a layer of fill material in the fill location abutting against the facing wedge, and compacting the layer of fill material so that it is compacted against the facing wedge. Then, placing an elongate non-extensible panel anchor on top of the layer of fill material, and attaching the elongate non-extensible panel anchor to the wall panel. At a next step, the facing wedge is moved up to a next course above the layer of fill material, and fabric sheet is installed. An additional layer of fill material is added and compacted with enough force to mobilize the fill. Finally, the method includes the steps of removing the facing wedge, and adjusting the elongate non-extensible panel anchor so that it is plum with the wall panel.

A border bench apparatus providing a seating surface that can be interchangeably replaced with a retaining wall section. The border bench comprises a bench section having a seating surface, a first end to engage a lower engagement projection, a second end adapted to engage an upper engagement projection, and a body. In the preferred embodiment, more than one spike passes through the hoes defined in the bench and the wall sections for stabilization. The border bench can include a weighted base, or a broadened base.

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.

An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosyuthetic reinforcement.

An apparatus and method for endwise connecting subterranean barrier members is disclosed. The apparatus includes at least two barrier members with each barrier member extending between top and bottom edges. Further, each barrier member has a side first edge having a flange defining a first connector and an opposed second side edge having a channel defining a second connector. The channel is sized and shaped to receive the flange of an adjacent barrier member in slidable interconnection therein. The apparatus further include a first side panel shaped to lie against a first side of the barrier members, a second side panel shaped to lie against a second side of the barrier members and a bridging plate located between the first and second panel members so as to bridge a gap therebetween, wherein the gap has a width corresponding to a width of the first and second barrier members. The associated method is directed toward creating the apparatus.

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.
