Floating Turbidity Barriers for Moving Water

Type 2 turbidity curtains are floating silt barriers used for sediment control in moderate-flow water conditions such as rivers, lakes, and tidal zones. Protecting waterways during construction begins with choosing the right containment solution, and One Clarion’s Type 2 turbidity curtain is that solution. Specifically designed for moderate moving water, this silt barrier helps municipalities and other public works agencies meet regulations and protect aquatic life.


Available in contractor/economy-grade and DOT-compliant models and with permeable and impermeable skirt options, these Type 2 turbidity curtains help keep construction runoff contained and meet DOT and NPDES standards. Durable, easy to deploy, and suited for roadwork, dredging, and shoreline projects, these turbidity barriers offer reliable, jobsite-ready compliance and performance. If you're looking for additional sizing, One Clarion offers custom options. Call our sales team to secure your turbidity barrier today.

  • Explore our Water Baffles – Water baffles are structures used to control water flow in tanks, ponds, or basins. They reduce turbulence, enhancing sediment settling and improving water quality.
  • Dewatering Tubes – Dewatering tubes are large, permeable geotextile bags used to filter and remove water from sludge, sediment, or waste materials. They efficiently retain solids, allowing clean water to drain out for easier disposal or reuse.
  • Bladder Tanks – Bladder tanks are flexible, collapsible containers used for temporary or long-term storage of liquids such as water, fuel, or chemicals. Their compact, portable design makes them ideal for remote locations, emergency response, and mobile operations.
