PURPOSE: To improve a slope face protection effect by a method in which upper and lower foundation cloths are formed by disposing warp and weft cross each other to provide meshes of such size as not to hinder the vegetation and the upper and lower foundation cloths are alternately connected so as to be disposed parallelly, spaced apart at a predetermined interval.
CONSTITUTION: An upper foundation cloth 3 which is constituted of imitation gauze or gauze fabrics prepared by disposing a large number of warps 1 and wefts 2 cross each other to provide stably fixed meshes of such size as not to hinder the vegetation and a lower foundation cloth 4 are provided, and the cloths 3, 4 are interconnected by twisted yarns 5 such as twines in the direction of warps 1 so that the cloths 3, 4 are parallelly disposed, spaced apart at a predetermined interval L. Further interval holding parts 5b are formed so as to be spaced at a predetermined interval A in the direction of warps and a plurality of twines 5 are provided so as to be spaced at predetermined intervals B in the direction of wefts 2 of the cloths 3, 4.
