Type 1 Silt Barrier
Floating Turbidity Curtain
Type 1 turbidity curtains, also called silt barriers or silt curtains, are designed for calm nonmoving water such as ponds, ditches, swales, canals, and lakes. They provide short-term sediment control for construction and maintenance sites where there is no current or tide.
Options include Economy (Contractor grade) and DOT Compliance Regulated models with Permeable or Impermeable skirts available. These curtains consist of modular 50 or 100 foot sections that install quickly and deliver reliable turbidity control at low cost.
Type 1 Turbidity Curtain Details
Type 1 turbidity curtains are used in calm water to control silt and sediment while meeting enviromental conmpliance on your jobsite. They include a float at the top, a fabric skirt that hangs down, and a weighted bottom to keep the curtain in place.
These floating silt curtain barriers come in 50 or 100 foot sections and install easily. Made from PVC impermeable fabric or geotextile permeable fabric, they offer a cost effective solution for short term sediment control in ponds, ditches, and canals. We even have customizable options for projects with specific jobsite requirements.

Silt Barrier Frequently Asked Questions
The silt barrier controls and contains suspended sediment in bodies of water. When soil is displaced through the effects of runoff and erosion, sediment can find its way into bodies of water, making it cloudy with turbidity. This cloudiness effects the ecosystems living in the water, limiting the amount of sunlight that nourishes plants, which in turn nourish the insects and animals there. By controlling this dispersed sediment, you reduce soil water pollution and its effects on the environment and ecosystems.
The DOT type 1 silt barrier is made to meet and exceed the DOT type 1 specification set about by the Department of Transportation in the United States. These specifications dictate the manufacturing of the silt barrier. For specific information on our DOT type 1 silt barrier, give our product specialists a call and find out what DOT type 1 specification you qualify for. For information about our other types of silt screen, see our type 2 and type 3 silt barrier pages.
