A method of manufacture of a barrage unit comprising providing a chamber having an outer wall having at least one aperture therein; providing a liner layer proximate to the aperture; blowing the fibers of a fibrous material into the chamber whilst providing an absorbent crystalline material to the chamber such that the two mix and exit the aperture onto the liner forming a pad; and, providing a further liner layer on the pad.

Certain exemplary embodiments can provide a system, machine, device, manufacture, and/or composition of matter configured for and/or resulting from, and/or a method for, activities that can comprise and/or relate to, a retaining wall system comprising a plurality of stacked courses of substantially horizontally-extending mesh tubes, each tube substantially filled with a plant growing medium.

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.
