Floating Turbidity Barriers

The ideal solution for sediment control

These barriers consist of a top flotation boom, an impervious fabric curtain extending downward underwater, and a heavy galvanized steel chain sealed into a hem along the entire bottom of the curtain to provide ballast to keep the curtain vertical in the water. End hems are sealed around a rope and grommeted to allow attachment to each other with rope or bolt/nuts/washers.

Floating turbidity barriers installed in moving water, tidal areas, and windy areas must be anchored to stay in position. Aer-Flo has developed a revolutionary system to ensure barriers are effectively anchored to stay in position. Our unique positioning/retrieval buoy is used to pull the barrier to proper position during installation, and to unhook the anchor from bottom during removal. Our floating turbidity barriers meet or exceed all DOT specifications and are second to none in quality, effectiveness and strength as they utilize our Tough Guy technology.

Optional barrier connectors:

• ASTM Aluminum “Z” Connectors
• Slotted PVC Tube Connector Seals

There are three major design types of Floating Turbidity Barriers. Type 1.DOT, Type 2.DOT and Type3.DOT.

HOW IT WORKS:

Designing Effective Barrier Installations

Floating turbidity barriers are effective in preventing silt and sediment migration into watercourses. However certain rules must be followed in order to make the installation successful. Three of the most critical rules are:

1. The silt and sediment must be contained in the retention area long enough to allow it to settle.
2. The preceding rule implies that the silt and sediment particle sizes will actually settle in the time allotted by the construction conditions. Click here to view the table showing the time required for particles of various sizes to settle one foot in calm water at 68° F.
3. The current in the containment area must not be so great that the particles are allowed to migrate beyond the barrier before settlement can occur. Barriers can handle current velocities up to five feet per second.
