<p>PROBLEM TO BE SOLVED: To provide an environment-friendly foundation for growth of plant by having a specified shaped hole in each net, arranging a projection type net provided with multiple crests and valleys having a specified height on a bottom part net, and pinching a fiber matrix in a space formed by the bottom part net and the valleys of the projection type net, and placing a vertex net so as to form a reinforced composite mat. SOLUTION: A super heavy projection type net 40 formed of multiple crests 46 and valleys 48 arranged with each other and extended in parallel with each other is arranged on a heavy bottom part net 30, and a fiber matrix 20 is pinched between the bottom part net 30 and the valleys 48 formed in the projection type net 40, and furthermore, a heavy vertex mat 50 is fixed adjacent to the crests 46 of the projection type net so as to form a reinforced composite mat 10. The bottom part net 30, the projection type net 40 and the vertex net 50 have multiple rectangular holes having a length at 1.56-50.8 mm and a width at 1.56-50.8 mm, and a height between the crest 46 and the valley 48 of the projection type net 40 is set at 3.18-25.4 mm. This reinforced composite mat 10 is laid in a water passage so as to provide an environment, which can prevent the intrusion of earth and seed from the water passage and which can help the fixation and grow-up of the plant.</p> |
