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: Great question! I'd be happy to let you know what you need to choose the correct type of Turbidity Barrier for your application.
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 Barrier.
Conditions to Consider for Turbidity Barriers
In order to provide an accurate assessment for our clients, we will normally request the following 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.

Typical 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.
