  • Patent number: 10267011
    Abstract: Provided is a pre-cast structural and/or decorative retaining walls, concrete walls that require moment restraints in one or two directions like retaining walls, monuments, levy walls, fences, building walls or any freestanding wall structure consisting of concrete walls constructed on a horizontal surface normally at a manufacturing facility, on rolling platforms or other substrate, or preferably built on the construction site where after curing the pre-fabricated walls can be installed at a site. The pre-cast panels can have a wide variety of decorative elements readily applied to both the upper and lower downside reflection surface. A unique feature is the buttress system that is added to the back of the wall system when elevated retention is required. By placing the buttress portion on top of the footing, and tying into the pre-decorated wall with reinforcement, an eco-friendly, design optional retaining wall system is accomplished which is rapidly and economically installed.

  • Patent number: 10087597
    Abstract: A stackable concrete wall block is disclosed having a body with an irregular front portion and a prism shaped rear portion, the irregular front portion has a three dimensional surface structure embossed in the front face providing the appearance of natural stone and the regular rear portion facilitating stacking of like blocks. The rear portion has parallel sidewalls perpendicular to a rear wall, which are more easily manufactured by dry casting than tapered sidewalls. A lip protrudes from at least one of the sidewalls of the rear portion and is coplanar with the front face for spacing the body of the block from that of a like block placed adjacent thereto. The lateral lip generates spacing between adjacent blocks at a back terminal edge, thereby allowing the assembly of curved walls. The irregular front face extends over the lip so that the front face is continuous over the lip.

  • Patent number: 8562260
    Abstract: A concrete block and a concrete block set for building a segmental retaining wall. Each block of the block set comprises front and back faces connected together by side walls extending between a top surface and a bottom surface. The shapes of the side walls create a lateral interlock system between adjacent blocks, and one of the side walls is preferably inwardly bevelled. Each block of the block set also comprises a longitudinal slot on the bottom surface. The blocks forming a first subset of the block set are provided with a vertical connector centered between said front and back faces, on the top surface, and sized to fit into the longitudinal slot located on the bottom surface of a block positioned immediately above in a segmental retaining wall. The blocks forming a second subset are not provided with such a vertical connector.

  • Patent number: 8496411
    Abstract: A two-stage MSE system for securing a facing to an earthen formation is disclosed. The system includes a wire grid laterally-offset from the facing and a formation anchor coupled to the wire grid. The formation anchor includes a face plate, a wave plate, and an eyebolt extensible through the face plate and wave plate to secure the plates on opposing sides of the wire grid. The wave plate has transverse protrusions that align with and seat adjacent vertical wires of the facing. A facing anchor is coupled to the facing and a turnbuckle assembly secures the facing to the wire grid by coupling to the facing anchor and the formation anchor. A soil reinforcing element may also be attached to the formation anchor.

  • Patent number: 8430603
    Abstract: A retaining wall block can include a top surface and opposing bottom surface, a front surface and opposing rear surface, and first and second opposing side surfaces. A projection can extend downwardly from the bottom surface and can include a forwardly facing indexing surface oriented generally parallel with the front surface of the block. The indexing surface can be configured to engage a rearwardly facing surface of a block in a lower course of blocks. The block can also include a pair of spaced apart key slots defined in the rear surface. Each key slot can include an enlarged interlocking portion and a throat portion extending from the interlocking portion to the rear surface. An assembly can be created whereby a pair of correspondingly shaped keys of an elongate barrier member are engaged with key slots of block so as to inhibit rearward horizontal displacement of the keys within the key slots.

  • Patent number: 8371086
    Abstract: A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. The wall block has a front and rear, top and bottom, and opposing sides. The top and bottom define respective substantially planar stacking surfaces. A shear lug projects from one of the planar stacking surfaces of the top and bottom. A block-locating jut is formed with at least one of the opposing sides, and projects from the side at a point intermediate the top and bottom towards one of the planar stacking surfaces. The block-locating jut defines a base surface substantially coplaner with the stacking surface, and a lug-engaging shoulder adapted for engaging a shear lug of a wall block located in an adjacent stacked course.
