What Are Type 2 Silt Curtains?
Type 2 Silt Curtains, also known as Type 2 Turbidity Curtains, are floating barriers designed to manage sediment in water during activities like dredging, marine construction, or shoreline restoration. These curtains are suited for sheltered waters, rivers, and inland waterways with small waves, low tidal movement, and mild currents.
Built for durability, they feature EPS floats for buoyancy, heavy-duty skirts, and ballast weights ranging from 1.2 to 6.5 kg/m for stability. The modular design with gapless panel connections ensures comprehensive coverage. Curtains are typically used where sediment control is essential to protect water quality and comply with environmental standards.
Ideal for low to moderate flow conditions, Type 2 Silt Curtains provide an effective, adaptable solution for sediment management while safeguarding aquatic ecosystems and reducing environmental impact. Proper installation and anchoring are crucial to their effectiveness.

How Type 2 Silt Curtains Differ from Other Turbidity Barriers
Type 2 Silt Curtains stand out from other turbidity barriers for their suitability for moderate water conditions. Unlike Type 1 curtains, designed for calm waters, Type 2 is built to handle small waves and mild currents, making it more versatile. They feature heavier ballast weights and stronger skirts, ensuring stability and effectiveness in low tidal environments.
Compared to Type 3 barriers, intended for high-energy environments, Type 2 Silt Curtains provide a more cost-effective solution for projects in sheltered waters or rivers where conditions don’t require heavy-duty designs.
This balance of durability and adaptability makes Type 2 Silt Curtains an ideal choice for inland waterways. They offer reliable sediment containment without overengineering.
Applications of Type 2 Turbidity Curtains
Type 2 Silt Curtains, also known as Type 2 Turbidity Curtains, are vital tools in various water management and construction projects. They are specifically designed for sheltered waters, rivers, and inland waterways where conditions include small waves, low tidal movements, and mild currents. Their effective design ensures sediment control while maintaining water quality and protecting aquatic ecosystems.
Type 2 Silt Curtains for Dredging and Marine Construction
Dredging operations often disturb large amounts of sediment, which can spread across water bodies and harm marine life. Type 2 Silt Curtains are an essential barrier in these scenarios, containing suspended particles within the work area and preventing them from dispersing into surrounding waters. Similarly, during marine construction projects such as bridge or pier building, these curtains ensure compliance with environmental regulations by controlling sediment drift and maintaining water clarity.
Type 2 Turbidity Barriers in Shoreline Restoration Projects
Shoreline restoration projects involve moving large volumes of sediment to repair or enhance coastlines. Type 2 Turbidity Barriers protect adjacent water habitats from sediment intrusion. By forming a physical barrier, they keep the construction zone isolated, allowing restoration work to proceed without negatively impacting water quality or nearby ecosystems.
Managing Sediment in Low to Moderate Water Currents
Type 2 Silt Curtains are engineered to perform effectively in environments with mild hydrodynamic activity, such as rivers and inland waterways. Their robust anchoring systems and flexible design keep them in place even with minor water movement. This makes them ideal for dam repairs, reservoir maintenance, and canal dredging, where sediment management is critical to project success.
Other Notable Applications
In addition, Type 2 Silt Curtains are used in water quality improvement initiatives, environmental protection during aquatic habitat restoration, and preventing contamination during stormwater runoff control projects. Their adaptability and reliable performance make them a preferred choice across multiple industries.
In all these applications, the proper selection, installation, and maintenance of Type 2 Silt Curtains ensure effective sediment containment, support sustainable practices and comply with environmental standards. Protecting water quality and aquatic ecosystems contributes to the long-term success of any water-based construction or restoration project.
Why Choose a Type 2 Turbidity Curtain?
Type 2 Silt Curtains and Turbidity Curtains offer a balanced solution for sediment management in aquatic environments with moderate water conditions. Their design ensures effective containment, environmental compliance, and adaptability to various project needs. Here’s why these curtains stand out:
