A Little History and A Lot of Photos of Monolithic Dome StoragesJune 29, 2005 by David B. South Monolithic Dome bulk storages have been constructed around the world to store chemicals, fertilizers, cement, sand, salt, feed, grains, aggregates, carbon, chips, seeds, peanuts, Coke, blasting powder and the list goes on. The benefits of utilizing Monolithic Dome construction technology for bulk storage can be learned by reading, Anatomy of a Bulk Storage.
One of the most interesting stories about storages comes from the Chandler, OK storage. We didn't have it quite finished when the salesman representing the fertilizer company saw what we were doing and he reported it back to his bosses in Catoosa, Oklahoma, at the OK Grain Company. OK Grain Company monitored the progress of the dome and after it was completed, ordered a dome for their river front facility. Before we could get mobilized to get there they decided they needed two. By the time we had the second one under construction they needed four more. So we wound up building six there on the river front. The tug boat captain started reporting what they had seen and it wasn't long before we were building on the Mississippi and the Missouri and the Tom Big B and the Columbia and most of the major rivers. This was a period during the eighties when fertilizer use was expanding tremendously over the United States. The construction of these large fertilizer storage facilities lead to other bulk storages-- especially cement. Bulk materials create tremendous bursting pressure in a storage. This huge amount of pressure can be best contained in a circle. The rebar used in the construction of the dome acts like hoops on a barrel. The bigger the building the more hoops. The domes also have another advantage in that the materials that settles falls away from the domes, rather than pushing the side walls down as is the case in a silo. This may not seem like much but it changes the foundation dramatically. The silo may need a foundation ten to twelve feet thick, the Monolithic Dome will only need one or two feet which is a tremendous cost difference.
