Turbidity Curtains

Type 1.DOT is the most frequently specified barrier in the TOUGH GUY® line. It is recommended for construction sites located in protected areas that are exposed only to light winds and to current velocities of less than one foot per second. This type of site may include ponds, shallow lakes, small streams and marshes.

Type 2.DOT is the work horse of the TOUGH GUY® line. It has 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, intercoastal and tidal areas where current velocities up to five feet per second are expected.

Type 3.DOT is a special adaption of the Type 2 barrier. Approximately 20 % of the area of the barrier skirt fabric is replaced with a polypropylene filter fabric conforming to some State DOT specifications. The filter fabric is inserted to reduce the pressure on the curtain while retaining silt.

This was another IA-DOT job that consisted of constructing a new clover-leaf intersection onto I-74. The medians were seeded with the IA-DOT Rural seed mix and the slopes were matted with single net straw blanket, while the ditches were covered using double net excelsior blankets. Other products that were used included our IA-DOT silt fence, scour protection and PP5-Xtreme, which is our Type 4 Turf Reinforcement Mat for the IA-DOT.
