<P>PROBLEM TO BE SOLVED: To provide a root-blocking structure using a root-blocking panel having excellent water-holding properties, water permeability and root-blocking properties, and facilitating construction; and to provide a greening structure and a root-blocking container. <P>SOLUTION: A water-resistant layer 14 is formed on a concrete layer 13 of a rooftop of a building, and a root-blocking layer 15 is formed thereon. The root-blocking layer 15 is formed by arranging the many root-blocking panels 10 obtained by pressurizing and molding a material obtained by adding a thermosetting resin as a binder to many shrunk fragments of magnetic tapes obtained by cutting or pulverizing the magnetic tapes, and heat-treating the resultant tapes so as to form curled shapes, to form a plane. A draining layer 16 and a water-holding layer 17 are formed on the root-blocking layer 15, and an added fertile soil layer 18 in which a plant 21 is planted is heaped on the water-holding layer 17. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
