Turbidity Curtains

A turbidity curtain, also known as a silt curtain, is a flexible, impermeable barrier used to trap sediment preventing the migration from a work site into a larger body of water. This curtain is generally weighted at the bottom to ensure that sediment does not travel under the curtain, which is supported at the top through a flotation system – or staked for applications with very limited exposure to water flow or wave action.

The type of turbidity curtain needed depends on many different factors, including how fast the water is moving, how much silt/turbidity is in the area, and the duration of your project. Land and Marine can help you determine the best turbidity curtain for your needs, offering standard and custom product solutions.
