Supersilt fence, a kit form of silt fencing, mainly includes two types: prefabricated silt fence with posts and wire backed silt fence without posts.
The Wire Back Silt Fence is a strong erosion control fence designed for areas with demanding silt and erosion control requirements. Offering more strength and stability than a standard silt fence, wire back silt fence includes wire fencing that lines the entire fabric of the fence. This strengthens the silt fence for use against large amounts of sediment or silt.
Prefabricated silt fence with posts comes preassembled as a unit, and is ready for immediate installation upon arrival at your site; wire backed silt fence without posts attached is also ready for immediate installation upon arrival at your site and it is a perfect choice if you have your own posts.
Following guidance of ASTM D6461 / D6461M - 16 Standard Specification for Silt Fence Materialsand ASTMD6462-03 Standard Practice for Silt Fence Installation, metal fences with 6 inch or smaller mesh openings and at least 2 feet high are utilized, fastened to the posts which shall have a maximum spacing of 1.2M and are constructed of heavy wood or metal as needed to support the geotextile fabric and withstand heavier sediment loading.
