A geogrid in the form of an integral, mesh structure includes molecularly orientated polymeric material, with the integral, mesh structure being formed of interconnecting mesh defining elements including elongate tensile elements. The molecular orientation of the integral, mesh structure is uniform throughout the extent thereof.

A mechanically stabilized earth (MSE) wall system that permits water drainage through joints while also preventing undesirable migration of backfill through joints, thus dramatically reducing or eliminating undesirable vegetation by incorporation of a free draining seal (FDS) in panel joints, wherein the FDS structure blocks backfill but permits water migration.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A reticular structure includes first elements distanced from each other and having an elongated conformation according to a first prevalent development trajectory, and second elements distanced from each other and having an elongated conformation according to a second prevalent development trajectory orthogonal, to the first prevalent development trajectory of the first elements. The first and second elements intersect at nodes to form meshes. The first elements have at a mid-portion defined between two consecutive nodes and orthogonally to the first prevalent development trajectory and a substantially T-shaped section including a base and a protuberance emerging orthogonally from the base. The second elements have, at a mid-portion defined between two immediately consecutive nodes and orthogonally to the second prevalent development path, a respective elongated base joined in a single piece to the base of the first elements to define a bottom surface of the reticular structure opposed to the protuberance of the first elements.

Geosynthetic reinforced wall panels comprising soil reinforcing hoop members and retaining wall system formed therewith is disclosed. Namely, a geosynthetic panel wall system is provided that includes at least one concrete facing panel that has at least one stabilizing hoop coupled thereto and wherein a soil reinforcing element or strip may be coupled to the stabilizing hoop. Additionally, a method of using the presently disclosed geosynthetic panel wall system reinforced with at least one stabilizing hoop and soil reinforcing element is provided.

A retaining wall structure of the present invention is a retaining wall structure comprising soil bags, each including: top and bottom surface portions having the largest area among surfaces constituting a soil bag body; and long side surface portions and short side surface portions forming side surfaces of the soil bag body between the top and bottom surface portions, wherein each of the long side surface portions of the soil bags is arranged to face the ground, the soil bags are stacked such that the long side surface portions are in contact with each other in the vertical direction with respect to the ground, the soil bags are arranged such that the short side surface portions are in contact with each other in the lateral direction with respect to the ground, and auxiliary retaining walls that are respectively disposed behind the stacked soil bags are provided.

Various embodiments of a mechanically stabilized earth (MSE) retaining wall that employ, for reinforcement, round rods with spaced pullout inhibiting structures (for example, round planar disks) are disclosed. The MSE retaining wall has at least one concrete panel. The panel has a generally planar body with a frontside, a backside, and a surrounding peripheral edge. The MSE retaining wall has at least one round, steel rod, the rod having a generally cylindrical elongated body with first and second ends. The first end is attached to the panel, and the elongated body and second end reside within backfill soil against the backside of the panel. The MSE retaining wall further includes at least one steel, pullout inhibiting structure residing along the elongated body of the rod. The pullout inhibiting structure has a body with a surface region that spans in a transverse radial direction from the elongated body of the rod. The rod passes through the body of the pullout inhibiting structure.

Multi-oriented segmental wall blocks, soil reinforcing system, and methods related thereto are disclosed. The wall block may be a concrete masonry block used for constructing retaining walls. The wall block may include a front face; a rear cavity opposing the front 5 face and formed by an inner rear face, an outer rear face on three sides of the inner rear face and spaced apart therefrom, and a shelf defined therein by the inner rear face and the outer rear face; a troughed top face residing between the front face and the outer rear face; a flat bottom face opposing the troughed top face; a first side face residing between the front face and the outer rear face, and between the troughed top face and the flat bottom face; a second side face opposing the first side face; a trough running along the length of the troughed top face.
