Our Silt fences act as a temporary barrier fabric used to retain erosion of silt and other sediment from polluting nearby streams, rivers, drains, and sensitive environments. Sediment such as sand, silt, and clay are considered as pollutants in storm water runoff systems. Silt fences act as a vertical permeable interceptor for areas exposed to sediment-laden waters.
It is important to distinguish that silt fences are not known to be used as erosion control devices, but are used for sediment control. They are commonly installed with support of poles, stakes, mesh wire, or a combination thereof. Mesh wire metal backing support provides the geotextile fence with increased strength to resist the weight of soil and water that may be present within a large drainage area or field.
Our woven silt fence fabric or silt barrier fabric is used as a temporary sediment control best practice to protect water quality. Our high performance fabric is capable of retaining soil but allowing water to filter through, thereby preventing sediment pollution of adjacent waterways.
The installation of silt fences follows local sediment control guidelines where supporting post spacing is typically no more than 2m apart and the silt fence extends to a height of 600mm above ground.
