GeoFence, sometimes called a "filter fence," is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes, and seas from sediment in stormwater runoff. It can be reinforced with wire, fencing, or netting. It can also be unreinforced and simply fastened to the geotextile along each wood stake.
The GeoFence silt fence is constructed with a 24”tall High Tensile Strength Polypropylene Geogrid Mesh, covered with a 36” woven slit tape polypropylene silt fence fabric. The silt fence fabric is attached to the geogrid reinforcement with galvanized c-rings. The rigid and high tensile strength geogrid mesh reinforcement supports the silt fence fabric in an upright position even under extreme storm events. The geotextile silt fence apron tag extends into the anchoring trench, providing anchoring and eliminating undercutting from extreme stormwater forces. GeoFence may be reinforced with either wooden or metal t-post stakes, which are typically placed on 6 to 8 foot centers.
