Stock Pile Cover - Installation Preparations

Large grain pile covers drain large quantities of rain water that must go somewhere. Be sure the floor of your storage area is higher in the center and slopes down and away from the pile area. In addition, a ventilations system with fans and generator backup is useful to draw the cover down against the grain pile during high wind conditions and for aerating the grain to maximize storage life. A 2' retaining wall built around the perimeter of the grain pile contains the grain within the designated area and provides a surface to fasten the grain tarp to.
