Triton Type 1 DOT Silt Curtain is the perfect containment option for calm water ponds, lakes, canals, and roadside swales. These turbidity barriers are used to contain silt and suspended solids in water. Silt Curtains limit the spread of pollution in water and help keep sites within compliance requirements. All Type 1 DOT silt curtains are designed for DOT applications and meet or exceed most state regulations.

The Type 1 DOT Silt Barrier is the strongest of the Type 1 models. It is designed for calm water areas with DOT regulations, long term projects, or significant silt requirements.

Choosing the Right Silt Barrier for Your Location

permeable silt barriersChoosing the right turbidity barrier for your location will depend on several factors, including water flow, wave height/frequency, and tides. Any time you are considering using a barrier for your location, we advise customers to review the following conditions on their location:

Water Conditions

  • How Fast is the Water Moving in your Location?
  • Are there Waves?
  • How High are the Waves and how Frequent?
  • What Tides are Present?

Site Conditions

  • In what Type of Project will this Barrier be used?
  • What is the Duration of the Project?
  • What Type of Material Will be Contained?
  • What is the Depth of your Water?
  • Is there Wind? If so, what is the Wind Speed?

While silt barriers come in standard sizes and lengths, they are also extremely adaptable. If you have a project with specific requirements, please don't hesitate to let us know. Curtains have been made with depths as short as three feet and as long as 100 feet.
