Floating Turbidity Barriers

These floating barriers are created with a top flotation boom, an inaccessible curtain that enters down into the water. Its designed with a heavy steel chain in the hem across the bottom of the curtain for ballast so the curtain remains vertical in the water. The end hems are sealed around the rope and an eyelet in the sheet allowing them to attach to each other using rope or bolts, nuts, or washers without tearing.

Aer-Flo has designed a revolutionary system to guarantee the barriers are anchored to remain in position in various elements including windy and moving water conditions. Their unique positioning or retrieval buoy is used to pull the barrier to its correct position during installation and unhook the anchor from the bottom for removal. Their floating turbidity barriers are next to nothing in quality, effectiveness, and strength using their Touch Guy® technology. The barriers meet or exceed all DOT specifications.

Protecting Water from Turbidity

Protecting Lake From Turbidity

There are 3 designs of the Floating Turbidity Barrier that you should know about. DOT 1, DOT 2, and DOT 3. All 3 have met or exceeded federal and state governmental specifications including the NPDES Phase II requirements.


This is probably the most requested barrier in the Tough Guy® Turbidity Barriers category. This is normally used in construction sites that are sitting in protected areas that are only exposed to very light winds and currents less than one foot per second. These sites are home to ponds, shallow lakes, marshes, and streams.

In some cases, anchoring might include stakes or possibly concrete blocks. The barrier sections are connected using rope or nylon ties.


This is considered the workhorse of the group. It comes with top load cables and primary stress plates for reinforcement of the corners and is capable of handing more serious conditions. It's perfect for lakes, inter-coastal, tidal locations, and streams where currents are up to 5-feet per second.

The anchoring and installation must be designed to match the site's location and conditions. You should get in touch with Aer-Flo or a qualified engineer for help when dealing with serious site conditions that might come your way. The barrier sections are connected using equipped shackles and rope lacing or nylon ties.


This is a significant adjustment to DOT 2 barrier. This will entail a 20% or higher of the area of the barrier skirt is replaced with a polypropylene fiber fabric that will conform with state DOT regulations. The fabric is placed to prevent pressure on the curtain while holding silt.
