Turbidity Barriers & Silt Curtain

Silt Barrier, Turbidity & Silt Curtain

Turbidity barriers, also known as floating curtains, silt barriers, or silt curtains are floating barriers designed to contain and control the dispersion of floating silt or turbidity in water. GEI Works manufactures a selection of Triton turbidity barriers to contain silt and keep your project site in compliance in every type of water condition.

Not sure which turbidity barrier is right for your project? Our Comparison Guide can help.

Triton floating turbidity curtains are recommended stormwater BMPs and help keep construction sites in compliance by controlling silt and sediment in water and allowing it time to settle. Triton DOT Turbidity Curtains meet USDOT requirements and exceed minimum guidelines outlined in the Florida DOT Erosion and Sediment Control Design and Review Manual. Triton Turbidity Curtains are available in standard and custom models to suit your project's needs.

Choosing Your Triton Turbidity Barrier

Choosing the right turbidity barrier or floating silt curtain for your location is highly dependent on several different site conditions. We urge customers to consider several factors and conditions, such as water flow/current speed, waves (height, frequency), wind (speed, direction), job type, and duration to determine the right barrier. If you have any additional site-specific requirements, please let us know those conditions. For more information about site specific projects, visit our custom turbidity barrier drawings page. To pick the correct barrier for your site, take a look at the chart below, or at our Triton Turbidity Curtain Comparison Guide (PDF).

How does a Turbidity Curtain Work?
Any time you are performing construction in or around a water body, the chance of pollution and/or suspended solids is high. In order to help limit the spread of these solids, turbidity curtains are placed around work areas, job sites, and dredging locations. This is important because increased sediment or disruption of sediment in water blocks sunlight for plants and harms aquatic life. Learn more about how a turbidity barrier can be used as a bid for a pond job site. Once turbidity barriers are implemented, solids are given increased time to naturally settle back down to the bottom of the water. This improves settling times for solids and helps protect natural resources from pollution. We offer Type 1, Type 2, Type 3, and custom models of Triton Silt Curtains (sometimes called turbidity fences) to fit your jobsite and specific applications. View our Type 1 Turbidity Curtain DOT page for more information.

Technical Resources for Silt and Turbidity Curtains

boom barriersTurbidity and Silt Curtains are an integral part of our erosion control equipment and product line. With the introduction of the Clean Water Act (1998) and subsequent NPDES phase II (National Pollution Discharge Elimination System), regulations have highlighted the importance of protecting our water resources from pollutants. When used correctly, these curtains can be an effective BMP (best management practice) for most job sites and project location. View our Permeable Silt Curtain page for more information.
