ABSTRACT:
A storage system for large quantities of flowable, granular materials, such as grain. The material is covered by flexible cover sections which are spread out on an impervious support surface and thereafter laced together to define a cover having a centrally located opening. The cover is grasped in the region of the central opening and lifted to a predetermined fill height; the perimeter of the cover being free to pull inwardly as necessary accommodating the lifting. Thereafter, the granular product is introduced into the opening until it reaches the predetermined fill height and defines a pile extending downwardly toward the support surface along a natural angle of repose. As the pile grows, it raises the cover while sweeping it upward away from the center of the pile. By this means the entire finished pile is conformably covered by the cover. After the pile has been established in its final configuration, the perimeter of the cover is fastened down, preferably to a retaining wall surrounding the base of the pile.
