Abstract
A method for stabilizing soil and reinforcing vegetation includes placing a single-layered, three-dimensional, high-profile woven geotextile fabric (10) into the soil.
The single-layered, homogeneous fabric (10) is woven from monofilament yarns (12, 14) having different heat shrinkage characteristics such that, when heated, the fabric forms a thick three-dimensional, cuspated profile. The monofilament yarns (12, 14) have a relatively high tensile strength and a relatively high modulus at 10 percent elongation so as to provide a fabric which is greater in strength and more dimensionally stable than other geotextile structures. Thus, the geotextile fabric (10) is suitable for use on slopes, ditches and other embankments and surfaces where erosion control, soil stabilization and/or vegetative reinforcement may be necessary. The homogeneous, single-component nature of the fabric (10) promotes easier handling and minimizes failure points, while offering a thick, strong and dimensionally stable product upon installation.

Claims (6)
1. A method of stabilizing soil and reinforcing vegetation comprising:
placing a single-layered, three-dimensional, high-profile woven geotextile fabric into soil.
placing a single-layered, three-dimensional, high-profile woven geotextile fabric into soil.
2. The method, as set forth in claim 1, further comprising:
covering said fabric with a layer of soil.
covering said fabric with a layer of soil.
3. The method, as set forth in claim 1, wherein said fabric includes two set of thermoplastic filaments interwoven in substantially perpendicular direction to each other, each said filaments having a pre-determined, different heat shrinkage characteristics such that, upon heating, said fabric forms a single-layered, three-dimensional, cuspated profile.
4. The method, as set forth in claim 3, wherein said fabric has a tensile strength of at least about 3200 pounds/foot in the warp direction and at least about 2400 pounds/foot in the filling direction, a modulus at 10 percent elongation of at least about 12500 pounds/foot in the warp direction and at least about 11000 pounds/foot in the filling direction, and a thickness of at least about 500 mils.
5. The method, as set forth in claim 2, wherein a resulting interface friction angle between said soil and said fabric of at least about 32° is provided.
6. The method, as set forth in claim 5, wherein said step of placing said fabric may be performed on side slopes having about 10° to 90° angles.
