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.

The invention describes a system for creating portable, porous structures for restoring coastline. The invention provides for a bag with multiple longitudinal pockets. The bag is made of porous natural or synthetic mesh material and the pockets are filled with lightweight, porous manufactured aggregate. In a preferred embodiment, the lightweight aggregate used in this invention is produced by thermal fusion of silicate clays in a rotary kiln. In another preferred embodiment, multiple bags are encased in a flexible grid material to form a mat. In another embodiment, the mat can be rolled into a log. The bags, mats, and logs can be placed on shorelines and other locations to restore coastline.

A wall module for a modular wall structure integrates a wall panel portion with a post portion having bottom extensions and at least one groove for receiving a distal end portion of a wall panel portion of an adjacent module. The bottom post extension may be suspended in a post hole and anchored with a material such as concrete.

Seawalls and methods for making seawalls are disclosed. A seawall may include a concrete footing, with a first plurality of anchorages disposed in the concrete footing. A plurality of precast concrete tee beams may include single-tee beams and/or double-tee beams. Flanges of the tee beams may be positioned to form seaward and landward faces of the wall, and stems of the tee beams may be coupled to the footing between the seaward and landward faces. A second plurality of anchorages may be disposed at tops of the stems. Elongate steel components extend through the stems, and are tensioned between the first plurality of anchorages and the second plurality of anchorages. Interior fill may be disposed between the seaward and landward faces. One or more wave deflectors may be disposed above the tee beams.

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.

Described is a kit for constructing retaining walls including multiple interconnecting units. Various units are provided including primary retaining wall units, end units, and corner units. Each unit is square or rectangular in shape and includes an interior volume, a lip on an upper end thereof, and a protrusion on a lower end thereof. The units can be stacked on top of one another and can be secured by engagement of the lip of a first unit with the protrusion of a second unit. The units can also be arranged side-by-side and secured to one another using securement posts and fasteners. The units include one or more exterior surfaces having a finished appearance that resembles wood, brick, or stone, among others. Further, each unit includes one or more drainage apertures thereon. In this way, the present invention provides a versatile system for constructing a retaining wall of a desired configuration.
