What is a silt fence used for in construction?

A silt fence is primarily used in construction to control erosion. It serves as a sediment barrier that helps prevent soil and sediment from being washed away by rainwater or surface runoff during construction activities. When installed around the perimeter of a construction site or areas where soil disruption occurs, the fence captures silt and sediment while allowing water to flow through, thereby reducing the likelihood of sediment polluting nearby water bodies or landscapes.

This use is particularly important in protecting the environment, as uncontrolled erosion can lead to significant soil loss and detrimental impacts on water quality. The function of a silt fence is specific to sediment control, distinguishing it from other construction aids, such as structural supports or insulation materials.

Understanding the role of a silt fence in managing erosion is crucial for construction practices, as it emphasizes the importance of maintaining site stabilization and reducing environmental impact during the construction process.
