Abstract
The present invention provides a ground surface structure for prevention of weed growing. The structure includes a germination-preventing sheet (2) resistant to penetration of buds of a plant and laid over the surface of a selected ground (1). The structure also includes a surface layer (3) formed by accumulating a water-repellent earth material on the germination-preventing sheet (2). The earth material includes material grains formed with silicone coating. Typically, the germination-preventing sheet (2) is made of a nonwoven fabric material and resistant to penetration of buds of a plant. Further, the sheet blocks the passage of light, but exhibits water permeability and air permeability.
Claims10
A ground surface structure for prevention of weed growing comprising:
- a germination-preventing sheet laid over a surface of a selected site, the sheet being resistant to penetration of buds of a plant;
- and a surface layer formed by accumulating a water-repellent earth material on the germination-preventing sheet, the earth material including grains formed with silicone coating;
- wherein the germination-preventing sheet is entirely buried under the surface layer of the water-repellent earth material;
- and wherein the surface layer allows water penetration.
A method of preventing weed growing at a ground, the method comprising the steps of:
- laying a germination-preventing sheet over a surface of a selected site, the sheet being resistant to penetration of buds of a plant;
- and forming a surface layer by accumulating a water-repellent earth material over an entire surface of the germination-preventing sheet, the earth material including grains formed with silicone coating;
- wherein the surface layer allows water penetration.
