A turf reinforcement fabric and a method for producing such a fabric by weaving a plurality of filaments in a predetermined pattern to form a three-dimensional structure formed to have a loft thickness without requiring the application of heat to heat shrink the fibers, and/or formed with one or more fibers of increased thickness at peaks and valleys of the woven structure, and/or incorporating flame retardant and/or UV stabilizing fiber additives.

1. A three-dimensional turf-reinforcement fabric comprising a woven array of fibers comprising a first plurality of warp fibers arranged in a first direction and a second plurality of weft fibers arranged in a second direction generally perpendicular to the first direction, the woven array of fibers
1. A three-dimensional turf-reinforcement fabric comprising a woven array of fibers comprising a first plurality of warp fibers arranged in a first direction and a second plurality of weft fibers arranged in a second direction generally perpendicular to the first direction, the woven array of fibers defining rows and columns of cells, wherein each cell comprises fiber segments of the first plurality of fibers and the second plurality of fibers being spaced at differing heights in a third direction perpendicular to the first and second directions, wherein at least a portion of the second plurality of weft fibers comprise fibrillated slit film polypropylene having a 2.5Z twist, and wherein a loft is formed in the three-dimensional turf-reinforcement fabric without requiring the application of heat. 2. The three-dimensional turf-reinforcement fabric of claim 1, wherein the woven array of fibers comprises a tubular or honeycomb pattern. 3. The three-dimensional turf-reinforcement fabric of claim 1, wherein the first plurality of warp fibers are selected from polypropylene, polyethylene, nylon, polyester, PVC, fibrillated slit film polypropylene having a 2.5Z twist, elastomeric fibers, other natural or synthetic fibers, and combinations thereof. 4. The three-dimensional turf-reinforcement fabric of claim 1, wherein the loft of the fabric is produced by control of at least one of the following parameters: loom tension setting, ends per inch of the weave, and weaving the pick construction into the fabric. 5. The three-dimensional turf-reinforcement fabric of claim 1, wherein the cells comprise alternating upper and lower crests defining a material thickness in the third direction therebetween. 6. The three-dimensional turf-reinforcement fabric of claim 5, wherein the first plurality of fibers arranged in the first direction comprise a plurality of fibers at each of the upper and lower crests. 7. The three-dimensional turf-reinforcement fabric of claim 5, wherein the material thickness is at least about 0.25″. 8. The three-dimensional turf-reinforcement fabric of claim 1, wherein the fibrillated slit film polypropylene of at least a portion of the second plurality of weft fibers provides additional strength to the fabric, and wherein the fibrillated slit film polypropylene does not cause excessive coverage of the fabric to extend above 90% shading. 9. A three-dimensional turf-reinforcement fabric comprising a woven array of fibers comprising a first plurality of warp fibers arranged in a first direction and a second plurality of weft fibers arranged in a second direction generally perpendicular to the first direction, the woven array of fibers defining rows and columns of cells, wherein each cell comprises fiber segments of the first plurality of fibers and the second plurality of fibers being spaced at differing heights in a third direction perpendicular to the first and second directions, wherein at least a portion of the first plurality of warp fibers comprise elastomeric yarn, and wherein a loft is produced in the three-dimensional turf-reinforcement fabric without the requirement of an application of heat. 10. The three-dimensional turf-reinforcement fabric of claim 9, wherein the woven array of fibers comprises a tubular or honeycomb pattern. 11. The three-dimensional turf-reinforcement fabric of claim 9, wherein the second plurality of weft fibers are selected from polypropylene, polyethylene, nylon, polyester, PVC, fibrillated slit film polypropylene having a 2.5Z twist, elastomeric fibers, other natural or synthetic fibers, and combinations thereof. 12. The three-dimensional turf-reinforcement fabric of claim 9, wherein the loft of the fabric is produced by control of at least one of the following parameters: loom tension setting, tension setting of the elastomeric yarns, ends per inch of the weave, and weaving the pick construction into the fabric. 13. The three-dimensional turf-reinforcement fabric of claim 9, wherein the elastomeric yarns of at least a portion of the first plurality of warp fibers allow for extension thereof such that the yarns are tensioned to a stretched length when forming the warp fibers and returned to an unstretched length that is shorter than the tensioned length after the tension is removed and the fabric is constructed. 14. The three-dimensional turf-reinforcement fabric of claim 9, wherein the cells comprise alternating upper and lower crests defining a material thickness in the third direction therebetween. 15. The three-dimensional turf-reinforcement fabric of claim 14, wherein the first plurality of fibers arranged in the first direction comprise a plurality of fibers at each of the upper and lower crests. 16. The three-dimensional turf-reinforcement fabric of claim 14, wherein the material thickness is at least about 0.25″.
