Silt Sock manufactures tube-based products for controlling erosion and reducing sediment. Silt Sock’s products also reduce heavy metals, minerals, and nutrients. These products are known as silt socks, filter socks, or sediment socks. The tubes are filled with properly sized and environmentally sound filter media. This media consists of compost, wood chips or other organic media. In addition to the finished product, Silt Sock also supplies fabric and equipment to produce filled socks.
