Silt Sock is a sediment-trapping device which uses filter media materials applied with a pneumatic blower device or equivalent. Silt Sock trap sediment by filtering the water passingthrough the Silt Sock™ also allowing water to pond, creating a settling of solids behind Silt Sock.

Silt Sock is used in any area requiring sediment control to keep runoff in the form of sheet flow. The use of Silt Sock applies to areas of high sheet erosion, on steep slopes up to and exceeding a 2:1 slope, and in other disturbed areas of construction sites requiring sediment control. Silt Sock may also be used in sensitive environmental areas, where migration of aquatic life is impeded by the use of other sediment controls. Filter media used in Silt Sock also have the ability to bind various contaminants contained in runoff.

Design Consideration

The sedimentation removal process associated with Silt Sock involves both filtering and deposition from settling. This is different than other methods using only ponding for deposition of sediment. Ponding occurs when water flowing to the Silt Sock accumulates faster than it can flow through the Silt Sock. However, installation technique is important for them to work effectively.

Benefits
