Type 1 Silt Barriers

Type 1 turbidity curtains, also referred to as type 1 silt curtains, are floating barriers that are designed to control various sediments or runoff in calm waters. There are two versions of type 1 curtains, including Type 1: Light Duty and Type 1: DOT. Type 1 DOT curtains are used in areas that require DOT (Department of Transportation) regulations. ABASCO offers Type 1 Light D/all-turbidity-curtains/uty and Type 1 DOT curtains for all calm water applications.
