What Sets Class 3 Turbidity Curtains Apart
Not all turbidity curtains are designed to perform in the same conditions. While Class I and Class II curtains are effective in calm or moderately active waters, Class 3 turbidity curtains are engineered specifically for high-energy, open water environments.
These heavy-duty containment systems are purpose-built for locations where strong currents, tidal movement, and wave action are a constant factor. In such conditions, standard curtain systems may fail to remain stable or contain sediment effectively. Class 3 curtains, by contrast, provide the strength and resilience required to maintain sediment control in exposed waterways.
The Challenge of Open Water and High-Energy Environments
Open water dredging and marine construction projects present unique environmental and operational risks. Strong currents, fluctuating tides, and wind-driven waves place sustained stress on sediment control measures.
Without a suitably robust containment system, these conditions can lead to:
- Loss of curtain stability and excessive movement
- Sediment escaping beyond the approved work zone
- Elevated turbidity levels affecting surrounding waterways
- Increased risk of environmental non-compliance and enforcement action
As a result, sediment control in open water environments demands equipment specifically designed for these forces.
Class 3 Turbidity Curtains as a Heavy-Duty Sediment Control Solution
Class 3 turbidity curtains are designed to perform reliably in demanding marine conditions. Their reinforced construction, combined with engineered flotation and ballast systems, ensures the curtain remains vertical and effective, even under continuous load from currents and waves.
By deploying Class 3 turbidity curtains, contractors can:
- Maintain sediment containment in exposed and tidal waters
- Reduce turbidity impacts beyond the work area
- Support compliance with environmental approvals and marine construction standards
- Protect sensitive marine and coastal ecosystems
Accordingly, they are the preferred option for high-risk and large-scale waterway projects.
Performance Specifications Designed for Open Water Conditions
Class 3 turbidity curtains supplied by Akuna are engineered with durability and performance in mind, ensuring suitability for extended deployments in harsh environments.
Materials
Manufactured from high-strength, UV-resistant fabrics designed to withstand prolonged exposure to sunlight, abrasion, and marine conditions without compromising integrity.
Flotation
Heavy-duty flotation systems provide maximum buoyancy, maintaining freeboard and curtain alignment in rough or variable water conditions.
Ballast and Anchoring
Robust ballast chains and engineered anchoring systems ensure the curtain remains vertical and stable, preventing sediment migration beneath the barrier even in strong currents.
Depth Configuration
Curtain depths can be configured to suit project-specific requirements, water depths, and environmental approval conditions.
Compliance with EPA and Marine Construction Standards
Class 3 turbidity curtains are designed to align with EPA guidelines and local environmental authority requirements for sediment and turbidity control. Their performance characteristics make them well suited to:
- Open water dredging operations
- Marine and port infrastructure projects
- Coastal construction and remediation works
- Exposed waterways with tidal influence
By specifying a Class 3 turbidity curtain system, project teams demonstrate due diligence and a proactive approach to environmental risk management.
Maintain Compliance in Challenging Marine Conditions
Effective sediment control in open water environments requires equipment designed for the realities of marine construction. Class 3 turbidity curtains provide the strength, stability, and reliability needed to manage turbidity and protect surrounding waterways.
