Silt Fences are temporary sediment control devices that prevent the release of silt from a construction site. Silt fences are rolls of permeable fabric stapled to wooden posts. These are installed along landscape contours to collect and filter sediment from sheet flow run-off. Silt Fences prevent silt contamination of sensitive areas such as neighboring properties, streams, and catch basins. A properly installed and maintained Silt Fence will collect silt before it can cause contamination requiring expensive cleanup. Silt Fences create a small puddle behind the fence that acts as a "stilling basin," allowing mud to settle. You want to use silt fences where the soil has been stripped of natural vegetation. The bare soil is easily eroded and can lead to the loss of large quantities of silt during a rainstorm or other run-off event. Features ? Preassembled fence with posts attached to the fabric ? Marker line on fabric shows anchor depth ? UV stable black fence fabric Applications ? Keep silt from leaving construction sites ? Protect streams and waterways ? Keep mud off streets and neighboring property ? Creates a physical barrier around the site ? Use around catch basins
