US Patent 7650715 Plant sheet and manufacturing method for plant sheet

A light-weight plant sheet including plant pieces between a base sheet and a top sheet is able to make growth by tearing the base sheet and top sheet, each having a mesh structure. The top sheet contains a paste to adhere the top sheet to the base sheet and to hold the plant pieces, and such a paste comes out of the fibers of the sheet when wet during the manufacturing process. When the plant sheet is placed on the desired surface, the plant pieces can grow using water and nutrition provided from the surface of the construction site and absorbed by the top sheet and the base sheet.
