Heavy Duty Curtains
ABASCO Type 3 Turbidity Curtains, also referred to as Type III Turbidity Curtains, combine our standard high-strength fabric with heavy duty tension members)above and below the flotation and at the bottom of the curtain), fabric reinforcement, and stress plates a the bottom skirt corners. They are ideal for silt and sediment control during dredging and marine construction activities in rivers, bays and waterways with moderate current, wind and wave activity.
