<P>PROBLEM TO BE SOLVED: To provide a water-shielding greening sheet with which water shielding and greening can be simultaneously performed in bare ground or slope whose soil quality is easy to liquefy. <P>SOLUTION: The water-shielding greening sheet 1 includes a primary layer 2 made of staple nonwoven fabric, and a secondary layer 5 made of filament nonwoven fabric having water repellency under the primary layer, wherein seeds 7 are held between the primary layer 2 and the secondary layer 5. The primary layer 2 is made of the staple nonwoven fabric whose fabric weight is 30-100 g/m<SP POS="POST">2</SP>so as to allow buds from the seeds 7 to pass through, and the secondary layer 5 has a coefficient of water permeability of 10<SP POS="POST">-6</SP>to 10<SP POS="POST">-4</SP>cm/s so as to allow roots from the seeds 7 to pass through. <P>COPYRIGHT: (C)2012,JPO&INPIT |
