The laying of a vegetation mat in close contact with a clad surface is achieved. The vegetation mat has a net, which prevents freezing or flow-away of vegetation material without the need for stretching a separate net. The mat comprises a layer of vegetation material selected from the group consisting of soil improvement material, fertilizer, organic material, vegetation seeds and combinations thereof, a front and back sheet, which are capable of being at least partly decomposed and are coupled together to wrap the vegetation material. A net having a mesh size permitting the budding and growth of the vegetation seeds, is provided on the front surface of the front sheet. |
