Abstract: To install a wall, a placement area for a set of prefabricated wall sections is determined. The placement area includes a starting end and a terminating end. A wall section of the set of prefabricated wall sections includes a first layer of urethane foam, a second layer of urethane foam, an extension and depression to mate with a corresponding depression and extension of another wall section of the set of prefabricated wall sections, and a through bore extending from an upper face of the extension, passing through the extension and exiting a lower face of the extension. During installation, surface vegetation is removed from the placement area in response to surface vegetation being present on the placement area, the soil is compacted in the placement area, and a first wall section of the set of prefabricated wall sections is placed at the starting end.
