Protective cover

A cover for protecting a mound of particulate material in outside storage from the effects of weather elements, said cover comprising:

• a generally rectangular double-ply canvas having a top layer fixedly attached to a bottom layer along respective edges of said top and bottom layers;
• a plurality of bladders disposed between said top and bottom layers of said canvas, each bladder being parallel to a next adjacent bladder and coupled thereto with a flexible conduit for fluid communication therewith;
• and
• means for filling said plurality of bladders with water, whereby said canvas is maintained upon the mound by the weight of said water-filled bladders.

A cover for protecting a mound of particulate material in outside storage from the effects of weather elements, said cover comprising:

• a generally rectangular flexible double-ply canvas having a top layer fixedly attached to a bottom layer with stitching along respective edges of said top and bottom layers;
• a plurality of bladders disposed between said top and bottom layers of said canvas, each bladder being parallel to a next adjacent bladder and coupled thereto with a flexible conduit for fluid communication therewith, each said flexible conduit having a pressure-actuated check valve for enabling water to flow through said conduit between an upstream bladder and an adjacent downstream bladder when water within said upstream bladder reaches a predetermined pressure relative to a respective pressure actuated check valve;
• and
• a plurality of inlet conduits, each inlet conduit having one end coupled to a respective bladder and a second end adapted to be coupled to a water hose for filling said respective bladder, each said inlet conduit having a check valve for preventing water received in a respective bladder from leaking therefrom.
