Type 3 Turbidity Curtain
Floating Silt Barriers for DOT Projects
Type 3 turbidity curtain are engineered for marine construction projects in areas with strong currents. These screens combine the robustness of PVC fabric with the filtration efficiency of geotextile material. This design allows for effective containment of sediment-laden water while permitting filtered water to pass through, maintaining compliance with environmental regulations. The permeable panel design not only reduces pressure on the curtain but also accelerates the settling process, enhancing overall efficiency. These curtains are typically used in projects that require adherence to DOT compliance standards for Type 3 silt screens.
Type 3 Turbidity Curtain Features
- Choice of 6 or 8" float
- 18 oz PVC and 6 oz geotextile filtration fabric
- Universal connectors, bottom corner stress plates, and more
Type 3 Turbidity Curtain Benefits
- Filters and contains suspended sediment-filled water
- Allows some flow-through while maintaining compliance
- Meets most DOT project requirements
Type 3 Turbidity Curtain details
Type 3 Turbidity Curtains are available in standard lengths of 50 feet and 100 feet. The most commonly requested depth is 5 feet. However, curtain panels can be manufactured in sizes ranging from 3 feet to 100 feet, giving you flexibility for different site conditions. For extended deployment in fast-moving water, such as near riverbanks or sediment settling areas, a Heavy-Duty Type 3 Turbidity Curtain is also available. This version uses 18 oz. or 22 oz. impermeable reinforced fabric, offering increased containment strength for longer-term performance in dynamic environments.

Type 3 Turbidity Curtain Applications & Accessories for Anchoring and Installation
Type 3 Turbidity Curtains are designed for demanding marine environments where water flow and sediment control are critical. These barriers are commonly used to manage turbidity during active construction or restoration projects in open water or high-energy zones.
- Bridge or pier construction in tidal or river conditions
- Marine dredging operations in bays or coastal zones
- Shoreline stabilization and restoration projects
- Containment for sediment-laden water near discharge outfalls
- Erosion control during bank reinforcement or slope grading
- Infrastructure work at ports, harbors, and bulkheads
Protect your floating silt barriers with proper installation using these marine accessories:
- Anchor Kits: pre-assembled for your convenience
- Tow Bridle: helps distribute weight and stress load to prevent damage during towing
- Reefing Lines: gives you control over how much curtain to unfurl for each panel section, so that the curtain isn't dragging and catching on the water body's floor
- Tidal Compensator: Adjusts automatically keeping the floating silt barrier positioned correctly with the changing tides
Type 3 Turbidity Curtain Frequently Asked Questions
In addition to the Type 3 silt screens, we also offer two other permeable models designed to filter sediment, silt, and other materials.
- Type 1 Silt Screens: Geotextile Silt Screen Curtains are designed for use in calm water areas such as ditches, streams, and other low flow areas.
- Type 2 Silt Screens: Used for remediation projects, long-term turbidity control, new infrastructure site control, and multiple deployments
Anytime you are implementing a floating silt barrier in salt water oceans or lakes, it is recommended that your barrier features Stainless Steel Cables and Zinc Anode Components. These components offer a higher resistance to corrosion, which is common with extended salt water use. If you are working on a short term project, standard galvanized components will work in salt water areas for a period up to 12 months.
