Silt sock is a mesh material on the outside filled with wood chips of specific sizing. It is an active water filtration opposed to straw bales or silt fence, which is more of a damming device for water, letting sediment fall out.
Erosion control silt sock is a type of sediment control product used to prevent soil erosion and sediment runoff during construction or landscaping projects.
The sock is filled with a soil or sediment filter fabric and is placed in areas prone to runoff or erosion. It helps to stabilize the soil and trap sediment, thereby reducing the risk of environmental damage and maintaining site cleanliness.
