Type 3 Silt Barrier

Floating Silt Curtain For Rough and Coastal Waters

type 3 silt barrierThe Triton Type 3 Silt Barrier is the highest strength option for silt and turbidity control in rough or moving water areas. Constructed from a robust 22 oz. PVC material these barriers feature tension cables, bottom ballast chains, and marine grade section connectors to maintain control in moving waters.

Designed specifically for demanding areas, Type 3 Floating Silt Curtain has been commonly used in intercoastal waterways, bays, harbors, coastlines, and fast moving rivers and lakes. Available models include impermeable and permeable curtain options.

Difference Between Type 3 Standard and Type 3 Permeable Silt Curtain

demanding silt curtainThe main difference between our standard Type 3 Silt Curtain and a Permeable Silt Curtain is the material of the bottom skirt. The standard design of a silt or turbidity curtain has an impermeable PVC bottom skirt that keeps silt, sediment, and other particles completely contained at the bottom level of the water area. By contrast, a permeable turbidity curtain has black geotextile filter panels sewn into the bottom skirt, which allows water to pass through the barrier while filtering and slowing suspendid solids.

While most locations will use an impermeable skirt, permeable skirts can be specified on jobs. Please let us know if the geotextile silt curtain is a requirement for your location.

Where has the Type 3 Silt Barrier been used?

The Type 3 Silt Barrier has been used in rough waters in a range of site locations. The robust design of the demanding silt curtain has also made them suitable for use on contaminated remediation projects (PCB's, DNAPL, etc.), brownfield development, and Coastal Development of new infrastructure, such as hotels and residential developments.

Choosing a Silt Curtain Model

type 3 floating silt curtainThe Type 3 Silt Barrier is used in more extreme conditions, including fast water currents, constantly changing tides, high wind speeds, frequent waves, and/or demanding project or site conditions.

For areas with less intense conditions, a better turbdity option may be either a Type 2 Silt Barrier (for moving water) or Type 1 Silt Barrier (for calm water). See more information on the Silt Barrier Differences among Type 1 Silt Barrier, Type 2 Silt Barrier, and Type 3 Silt Barrier.

Salt Water Conditions

When implementing a floating silt barrier in salt water oceans or lakes, it is recommended that your barrier features a Stainless Steel Cable and Zinc Anode Components. These components offer a higher resistance to corrosion which is common with extended salt water use. For short term projects, standard galvanized components will work in salt water areas for up to 12 months.

Silt Curtain: Factors and Considerations

type 3 turbidity curtainWhen choosing a silt or turbidity barrier, there are several factors you should take into consideration:

  • Water Velocity
  • Tides
  • Wind Speed and Direction
  • Wave Height and Frequency
  • Layout, Scope, and Duration of the Project
