Choosing a Turbidity Barrier
FAQ: How Do I Choose the Right Type of Barrier?
Question: I need helping choosing a turbidity barrier. I see several options here and I'm wondering how to know which type of turbidity barrier I need?
Answer: When choosing a Turbidity Barrier, typically the type needed is chosen based on your water and site conditions. While options like the Type 1 are perfect for calm water applications, moving waters will require higher strength options such as the Type 2 or the Type 3 Turbidity Barrier.
Turbidity Barrier Site Considerations
In order to provide an accurate turbidity barrier assessment for our clients, we will normally request the following site considerations information:
- Site Conditions
- Water Velocity
- Waves (height, frequency, etc)
- Wind Speed and Direction
- Soil Type (contaminated?)
- Project Duration
- Site Specific Requirements and Project Specifications
In addition, if the project is environmental remediation, like pcb (heavy metals) removal, capping or brownfields (coal tar) site development, we may suggest a site survey/walk to get an in-depth understanding of the entire requirements.

Turbidity Curtain Applications
In general, the turbidity curtains are designed for several general conditions based on their type. The following can be seen as a general guide as to how and where each type can be used:
- Type 1 Turbidity Curtain: The Type 1 is ideal for calm water applications, such as roadside swales, small ponds, and lakes.
- Type 2 Turbidity Curtain: The Type 2 is the medium-level barrier and is used in several moving water conditions up to 1.5 knots and 36" waves. This includes use around dredging areas, rivers, lakes, and more.
- Type 3 Turbidity Curtain: The Type 3 is the highest strength option and is designed for the most demanding water conditions, such as intercoastal waterways, bays, harbors, and large lakes.
