Type 2 Floating Barrier
Type 2 Silt Curtain for Moving Water
The Type 2 Floating Barrier, also known as a Heavy Duty Turbidity Curtain, is designed to meet EPA regulations for marine construction projects. These barriers are ideal for job sites with moderate current conditions, effectively containing sediment in areas with current velocities up to 1 knot, tidal influences, and moderate winds.
Built to handle demanding environments, Type 2 Floating Barriers are available in DOT-compliant, Contractor-grade, and Heavy Duty (HD) options, ensuring a tailored solution for a variety of project requirements. Additional models are offered to address specific site needs, making these barriers a versatile choice for maintaining water quality and ensuring compliance during construction activities.

Type 2 DOT Floating Barrier Details
Note for Salt Water Projects with Floating Silt Barrier: When construction projects are exposed to salt water, we recommend using stainless steel cables and zinc anode componets with your floating barrier. These components offer a higher resistance to the corrosion that is common with salt water exposure. However, standard galvanized components will be sufficient for short term projects.
Additional Products and Information for Anchoring and Installation
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
Additional Type 2 Floating Barrier Models
For short term turbidity control in construction or dredging projects, Type 2 turbidity curtains are also available in contractor and DOT grade models. These curtains feature impermeable 13 oz or 18 oz pvc fabric for effective containment around your job or construction site.
- Type 2 HD
- Type 2 HD Permeable
We make Floating Barriers with options and models to accommodate water conditions that range from calm water to fast water. Additional models include Type 1 DOT, Type 2, and Type 3 Floating Barriers. For our complete product line, please see Floating Turbidity Curtains.

Type 2 Floating Barriers Applications
For many projects and locations, having a higher strength curtain is essential to keeping the barrier in position during extended use. In extended use applications, Type 2 HD and Type 2 HD Permeable can be a more reliable option. Made from a fabric with increased strength, these curtains are able to accommodate pressure from dredging projects, construction projects, shoreline repair, river bank construction erosion containment, and more. Floating Barrier Type 2 Models:
- Type 2 HD (Heavy Duty) Curtain
- Type 2 HD (Heavy Duty) Permeable Curtain
When compared to contractor grade curtains, HD models offer a couple of added strength options. Fabric: 13 oz/18 oz vs. 22 oz - The first difference between contractor and HD models is the type of fabric. HD models will feature a minimum 22 oz fabric to retain strength in moving water locations, while contractor curtains feature less robust 13 or 18 oz PVC material. Top Connector: Top Stress Plate vs. Bulk Connector - The second difference between these models is the top connector. HD models use a higher strength universal bulk connector. This is able to accommodate increased loads and stress.
Type 2 DOT Floating Barrier Frequently Asked Questions
The main difference between DOT type 2 and heavy duty silt curtain is the fabric and the section connectors. A DOT silt curtain features a top connector plate, while the heavy duty model features a full slide connector between each section, and the heavy duty silt curtain uses a heftier fabric.
Yes, the type 2 silt curtain can be adjusted to handle saltwater conditions. During the manufacturing process, some components are changed for projects with saltwater conditions. For instance, the tension cables are instead made with stainless steel and the connectors are made with zinc anode for deployment in salt water.
