Invisible Flood Control Wall - East Grand Forks

The unusually high concrete wall base was an optional choice that dictates that flood waters must significantly rise before the planks have to be mounted
Intermediate and vertical parting supports bolt into anchor devices mounted deep in concrete wall base.
20' sealed aluminum planks stack into place
Pin connected diagonal braces support wall when exposed to flood load. A threaded tension rod allows perpendicular mounting of wall. Concrete thrust blocks absorb diagonal stress during flood times
Teams of assemblers work different sections of wall to speed process. The "FCA" logo establishes "dry side" orientation of aluminum planks.
