Turbidity Barriers are a BMP designed to restrict the flow of sediment-laden storm water runoff from a construction site, to keep it contained in a limited area, and allow the sediment to settle out before being carried into adjacent or joining watercourses. TOUGH GUY® Turbidity Barriers are manufactured by AER-FLO, Inc., the world’s largest producer of these critical devices.

This is the workhorse of the TOUGH GUY® barrier line. Each Barrier comes supplied with a top load cable and special stress plates for reinforcing the corners and is designed to handle more severe
conditions. It is recommended for lakes, streams, inter-coastal and tidal areas where current
velocities up to five feet per second are expected.

The anchorage and installation must be designed to meet the site conditions. Contact Aer-Flo or a qualified engineer for assistance when extraordinary site conditions are encountered. Barrier sections are connected by rope lacing or nylon ties and supplied separately.
