Turbidity and Silt Curtains
The turbidity curtain (also referred to as the silt curtain, silt screen or floating barrier) is a containment device designed to contain or control silt and turbidity during dredging, marine construction, or roadside construction activities. These control curtains are made in a standard Type 1, Type 2 and Type 3 curtain for various water conditions.

Choosing a Turbidity Curtain
The most common floating curtain design includes a barrier that features a top flotation device, impermeable skirt (depth dependant on your location) and bottom chain.
If your curtain will be used in a location with moving waters, curtains will additionally feature a tension cable located along the barrier to help stabilize the curtain in currents, waves and tidal conditions. Standard barrier types include a Type 1, Type 2 and Type 3 Curtain.
Turbidity Curtain Factors
If you are unsure of which type will work best in your water conditions, we often urge our customers to consider both their water and site conditions to help determine the best option for your location. Standard questions and considerations include the following:
- Water Conditions:
- Water Velocity: How fast is the water moving?
- Waves: Are there waves? How high/often do they occur?
- Tides: Are there tides?
- Water Velocity: How fast is the water moving?
- Site Conditions:
- Particles: What type of silt, turbidity or sediment are you trying to contain? Is it contaminated?
- Project: What type of project is this barrier for? How long will the project last?
- Wind: Is there wind? What is the speed and/or direction?
- Particles: What type of silt, turbidity or sediment are you trying to contain? Is it contaminated?
Specialty Turbidity Curtains
In addition to the standard floating containment curtains, we also offer several specialty floating silt curtains available to control silt, falling debris, and contaminants during unique projects such as bridge or dam repair, piling cleaning or pile extraction. Rather than the standard floating barrier design, these curtains will feature unique shaped or constructed materials specially designed to fit your application. Options include:
- Piling Extraction Curtains: Shaped specifically to fit around piling for containment during extraction, installation or cleaning.
- Barge Curtains: These curtains feature a foamless design that allows the curtains to hang directly from the barge area. Curtains will flow down to complete contain your materials during barge dredging operations.
Turbidity and Silt Curtain Options
As a general guideline on how each barrier type is typically used, please view the list below:
- Type 1 Silt Barrier: Calm Water Conditions
- Type 2 Silt Barrier: Medium/Moderate Water Conditions
- Type 3 Silt Barrier: Rough Water Conditions
Other Barrier Options
In addition to the standard turbidity and silt curtains, we also offer several barriers and containment items for specific applications or areas. These barriers are often uniquely shaped, styled, or designed to fit difficult containment areas such as under bridges, dams, piling, dredging barges, and more.
