GeoCurtain™ Class 2 Silt Curtain – River & Moderate Conditions

Description

Class 2 Silt Curtains for Moderate Hydrodynamic Conditions

GeoCurtain™ Class 2 systems are engineered for medium-risk environments with moderate wind, current and water movement.

Typical applications:

• Rivers
• Inland waterways
• Calm harbours
• Mining discharge zones

These systems are designed to maintain stability under increased hydraulic loading compared to Class 1 systems

Engineering Specification

• Floatation: 100mm–150mm closed cell foam
• Skirt: 260gsm nonwoven geotextile
• Float chamber: 400gsm – 610gsm PVC
• Reinforcement:
  • High tensile webbing (2T breaking strength)
  • Structural reinforcement layers
• Connectors:
  • Mechanical interlocking connectors
  • Marine-grade skirt connection system
• Ballast: 6mm chain (continuous pocket)
