Geotextile: Woven filter fabric inserted into skirt of no less than 20% of skirt area

All main body seams are heat sealed. All geotextile seams are sewn double needle, black thread
5/8” diameter poly rope reinforced vertical edges
#5 brass grommets
5/16” galvanized steel 7×19 load cable with PVC coating in top, 10,000 lb. break strength
5/16″ galvanized chain ballast
Aluminum stress plates at cable and chain terminations

EPS flotation foam: 8” x 8” (standard. Increases to 10” x 10” and 12” x 12”- Based on curtain depth),
26.7 lb./ft. buoyancy in fresh water and 28.4 lb./ft. buoyancy in saltwater

– Environmentally Sensitive Area Protection
– Areas with severe conditions, with high wind and water velocities of 5 ft/sec
– For lakes, streams, inter-coastal and tidal areas
– Enhance current Perimeter Sediment Pollution Control Measures
where current velocities up to five feet per second are expected.

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.

An Adaption of the Type 2.DOT, this special barrier has had 20% or greater of its curtain fabric replaced with a polypropylene filter fabric to help reduce pressure on the curtain while retaining silt.

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.
