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.

A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.

A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.

A segmented wall system includes a first course extending in a first direction and comprising a first wall block and a second wall block. A rear side of the first wall block is connected to a first side of a first tail block and a rear side of the second wall block is connected to a first side of a second tail block. The segmented wall system further includes a second course stacked on the first course. The second course includes a third wall block having a rear side connected to a first side of a third tail block. The rear side of the third tail block has a width in the first direction that is equal to or greater than a width in the first direction of the rear side of the third wall block.

The present invention provides an embankment wall structure (1000) comprising a plurality of facing panels (100) extending upwardly from a support surface and adapted to be stacked alongside in a horizontal as well as vertical direction. The plurality of facing panels (100) includes a plurality of monolithic facing panels (120), a plurality of first changer panels (140), a plurality of second changer panels (160), and a plurality of standard facing panels (180). Each monolithic facing panel (120) is stacked side by side with each first changer panel (140) at a desired stretch, and each second changer panel (160) is stacked adjacent to one monolithic facing panel (120) and opposite to one first changer panel (140), at a desired position in a top layer (200) of the wall (1000). Further, each of the uppermost standard facing panels (180) is in contact with either of the panels or combinations thereof.

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 geosynthetic reinforcement.

Structures, particularly wall and/or pillar structure, comprising a supporting portion and a covering portion for covering the supporting portion, the supporting portion being provided by solid material pieces and at least one string for jamming at least some of the solid material pieces, wherein the covering portion comprises at least one covering device and wherein the string and the covering device are attached to each other.

A retaining wall installation process for earth and water retaining wall, first step starting from preparing precast reinforced concrete heavy duty retaining wall (1) on the ground, inserted horizontal rebars (12) at each fin (7) passed to the holes (8), connected mechanical couplers (14) only one end of horizontal rebars. Attached shuttle-platform (16) to precast reinforced concrete heavy duty retaining wail (1). Then lift up to installed the wall at construction site, put down the vertical rebars (15) connected to the lower vertical rebars by using mechanical couplers (14), tie vertical rebars to horizontal rebars, then closed the vertical cavities (24) by using panel closer (28) and poured fresh concrete (29). After final setting time, removed shuttle-platform down to the ground.
