Silt Fence

I need silt fence for a small drainage area on my construction site. What is the fabric used and can you give me any details on efficiency? Thank You.

Hello, and thank you for contacting Granite Environmental! This is something that I can certainly help you with. Our silt fence sheets of geotextile material such as polypropylene, nylon or polyester. They have a tensile strength at 20 % (maximum) and should allow for standard strength of 30 lbs/linear inch (minimum). Furthermore, they have an ultraviolet radiation allowance of 90 % (minimum) and a 0.3 gal/ft2/min (minimum) slurry flow rate. Finally, our silt fence has a filtering efficiency of 75 - 85 % (minimum), which is highly dependent on local conditions.

USEPA (1993) reports the following effectiveness ranges for silt fences constructed of filter fabric that are properly installed and well maintained: Average total suspended solids removal of 70 percent, sand removal of 80 to 90 percent, silt-loam removal of 50 to 80 percent, and silt-clay-loam removal of 0 to 20 percent. Removal rates are highly dependent on local conditions and installation.
