The salt processing dome, with an inside diameter of 173 ft and a dome peak of 65 ft, houses equipment for processing and packaging bulk rock salt for commercial sale. The shell structure was constructed in 1985 by placing a nominal 3-1/2 in. of shotcrete over an inflatable fabric dome formwork. The concrete dome was exhibiting signs of deterioration and needed repairs to extend its useful life. SGH evaluated the dome’s condition and designed repairs.
