This invention relates to generally to geosynthetic materials which can be used for earthen reinforcement, and more particularly to a novel geosynthetic material exhibiting less strain under an initial tensile load then presently available geosynthetic materials. The novel geosynthetic material includes a first plurality of spaced-apart generally parallel fiber strands, a second plurality of spaced-apart generally parallel fiber strands positioned adjacent to and forming a plurality of intersections with at least a portion of the first plurality of strands, an organic tying member fixedly connecting portions of fiber strands of the first plurality of fiber strands with intersecting corresponding portions of the second plurality of fiber, and a bonding agent adhering predetermined regions of selected fiber strands of the first plurality of fiber strands with predetermined regions of selected fiber strands of the second plurality of fiber strands, wherein at least a portion of the fiber strands selected from the group consisting of the first plurality of fiber strands, the second plurality of fiber strands and combinations thereof comprise glass fibers. The present invention also relates to a novel geosynthetic composite including the novel geosynthetic material in combination with a second geosynthetic material, e.g. a geotextile fabric or geomembrane. The present invention also relates to a novel reinforced soil composite which includes a soil material in combination with the novel geosynthetic material of the present invention.
