WavePlus Silt Curtains for Marine Construction & Environmental Safety

WavePlus silt curtains floating barrier deployed for coastal sediment control in marine construction

Marine and coastal construction projects are vital for global development, ranging from port expansions and bridge constructions to shoreline protection and offshore energy installations. While these endeavors drive progress, they inherently disturb underwater environments, releasing sediment into the water column. This “turbidity” – the cloudiness caused by suspended particles – poses a significant threat to delicate marine ecosystems, water quality, and can even impact project timelines and regulatory compliance.

At Skytech, we recognize the critical balance between necessary development and environmental stewardship. Our WavePlus Silt Curtains, also known as turbidity curtains or sediment barriers, are meticulously engineered floating barriers designed to control the spread of disturbed sediment during marine construction and dredging operations. They act as an essential environmental safeguard, ensuring cleaner waterways and healthier ecosystems.

The Hidden Threat: Sedimentation in Marine Environments

Underwater construction activities like dredging, piling, and excavation inevitably churn up the seabed, releasing fine-grained material like silt, clay, and sand. This suspended sediment causes several detrimental impacts:

  • Reduced Water Clarity (Turbidity): High turbidity blocks sunlight penetration, which is vital for photosynthetic organisms like seagrass and corals, forming the base of many marine food webs.
  • Harm to Marine Life: Suspended particles can clog the gills of fish, making it difficult for them to breathe. They can also smother sensitive benthic (seabed) communities, including shellfish and corals, leading to habitat degradation and population decline. The effects of sedimentation on marine ecosystems are well-documented by environmental bodies like NOAA’s Office for Coastal Management.
  • Habitat Degradation: As sediment settles, it can bury existing habitats, spawning grounds, and foraging areas, disrupting the natural balance of the ecosystem.
  • Regulatory Non-Compliance: Many countries and regions have stringent environmental regulations requiring sediment control during in-water work to prevent pollution and protect aquatic resources. Failing to comply can lead to fines, project delays, and reputational damage.
  • Impact on Visibility: For divers, underwater inspection, or even recreational activities, excessive turbidity significantly reduces visibility.

WavePlus Silt Curtains: Your Essential Environmental Shield

WavePlus Silt Curtains are vertical barriers made of durable geotextile fabric suspended from a flotation collar and weighted at the bottom. They are strategically deployed to encapsulate a construction zone, allowing water to pass through while containing the suspended sediment within the work area. This promotes the natural settlement of particles, preventing their dispersion into surrounding sensitive waters.

Our range of WavePlus Silt Curtains is designed for superior performance and adaptability in diverse marine environments:

  • High-Strength, Durable Fabric: We utilize robust, UV-stabilized geotextile fabrics that resist tearing, abrasion, and degradation in saltwater environments. These materials are chosen for their optimal permeability, allowing water flow while effectively filtering out sediment.
  • Engineered for Various Conditions: WavePlus Silt Curtains come in different types, categorized by their suitability for various water conditions:
    • Type I (Light Duty): Ideal for calm, sheltered waters with minimal currents and wave action, such as ponds, small lakes, and protected harbors.
    • Type II (Medium Duty): Designed for moderate currents and wave action, suitable for marinas, larger bays, and rivers with some flow.
    • Type III (Heavy Duty): Constructed for demanding environments with strong currents, significant wave action, and offshore applications, featuring reinforced materials and stronger ballast systems. 
  • Optimized Flotation and Ballast: Each curtain type features robust flotation elements to maintain upright stability and a heavy ballast chain at the bottom to ensure the skirt remains vertical and extends to the required depth, preventing sediment from flowing underneath.
  • Modular and Customizable: WavePlus curtains are supplied in modular sections that can be easily joined to create barriers of any length. They can be tailored in depth to suit varying water depths, from shallow shorelines to deeper marine construction sites, providing maximum containment efficiency.
  • Easy Deployment and Retrieval: Designed for practicality, our silt curtains are relatively lightweight and manageable, allowing for efficient deployment and retrieval, minimizing operational time and costs.
  • Compliance Support: Utilizing WavePlus Silt Curtains demonstrates a commitment to environmental best practices and helps projects comply with local, national, and international environmental regulations.

Key Applications in Marine Construction and Beyond:

WavePlus Silt Curtains are essential for a wide array of projects where sediment control is critical:

  • Dredging Operations: Containing turbid plumes generated during the removal of sediment from waterways.
  • Pile Driving & Bridge Construction: Preventing sediment stirred up by foundation work from spreading.
  • Shoreline Protection & Reclamation: Managing runoff and disturbed sediment during coastal development and erosion control projects.
  • Pipeline & Cable Laying: Minimizing the impact of seabed disturbance during underwater infrastructure installation.
  • Marina & Harbor Development: Maintaining water clarity during construction or maintenance of berths and channels.
  • Environmental Remediation: Containing contaminated sediments during specialized cleanup operations.
