Type 2 Turbidity Curtain

Type 2 Turbidity Curtains

Type 2 turbidity curtains are best used to contain silt and turbidity in moving water applications. Type 2 curtains are manufactured using high strength fabric with heavy duty tension members, along with aluminum stress plates that the bottom skirt corners. These type 2 turbidity curtains are best used in dredging and marine construction areas that experience mild current, wind, and wave activity. ABASCO manufactures DOT (Department of Transportation) certified type 2 turbidity curtains.
