What is a Type 3 Heavy Duty Turbidity Curtain and who is it for?


Enviro-USA’s Type 3 floating silt curtain is ideal for containing silt and controlling turbidity in TIDAL applications where wind, current and tide changes require a heavy duty, dual cable barrier. Floating Turbidity Barriers are used to control and contain silt and sediment within an immediate work area thereby preventing anything from floating outside of the work or dredging area and affecting marine life. Floating Turbidity Barriers protect our waters, marine life and environment.

Type 3 DOT Heavy Duty / Tidal Water Floating Turbidity Barriers are normally used by contractors while working at shoreline and ports. Normally required and used by contractors or dredging companies during any marine construction project that is in a tidal application.

Why use an DOT Type 3 Heavy Duty Turbidity Curtain vs. another type of barrier:

The Type 3 model is recommended when compliance with United States DOT floating turbidity curtain requirements is a factor and the marine construction project happens in tidal water application. The heavy-duty design and construction help the barrier withstand the daily tidal forces.


Where are DOT Type 3 Heavy Duty Turbidity Curtains used? Recommended Applications are:

  • Harbors
  • Ports
  • Shoreline
  • Offshore


Floating Turbidity Curtains are available as Permeable or Non-Permeable, in 50 & 100 ft sections or any custom length up to 100’. The depth is available as required by project requirements and can be as deep as 50 ft. Numerous sections can easily & quickly be connected together.

Enviro-USA’s Type 3 Floating Silt Barriers are available with a Permeable or Non-Permeable skirt.  A permeable skirt is important if there is the need to allow water to flow through while containing silt or turbidity. Enviro-USA’s Floating Silt Curtains are manufactured in accordance and in compliance with most United States DOT requirements.  

Float size is determined by skirt depth and or your job requirements
