Abstract
A method for stabilizing soil and reinforcing vegetation includes placing a single-layered, three-dimensional, high-profile woven geotextile fabric into the soil. The single-layered, homogeneous fabric is woven from monofilament yarns having different heat shrinkage characteristics such that, when heated, the fabric forms a thick three-dimensional, cuspated profile. The monofilament yarns 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 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 promotes easier handling and minimizes failure points, while offering a thick, strong and dimensionally stable product upon installation.
