Abstract
A woven silt fence fabric is configured to have: a tensile strength greater than 140 pounds per ASTM D-4632 in the machine direction (MD); a tensile strength greater than 140 pounds per ASTM D-4632 in the cross machine direction (CMD) per ASTM D-4632; and one or more parameter(s) (per an ASTM test method) in the machine direction (MD) equal or approximately equal to the one or more parameter(s) (per the ASTM test method) in the cross machine direction (CMD). The woven silt fence fabric includes one or more marker yarns having a different color than adjacent yarn(s) to thereby identify one or more of a grade line, an install line, a monitor line, and/or a high visibility line.
