A Type III turbidity curtain is a heavy-duty marine barrier engineered to control sediment and particles in the most demanding marine environments, including areas with high currents, significant wave heights, and deep water. These curtains are ideal for offshore oil and gas exploration, deep water construction, and dredging projects, as they can endure extreme weather, strong currents, and high waves.

Constructed with foam-filled floats (Freeboards) and skirts ranging from 5 to 50 feet, with options for over 100 feet, Type III silt curtains provide robust performance. They feature aluminum end connectors combined with grommets on reinforced side seams. Connector plates are secured with toggle pins, and grommets are fastened using rope, nuts, and bolts for added durability.

PRODUCT OVERVIEW

    • Moving waters with some waves, wind, or tidal action

    • Rivers, Bays, and other waterways

    • Currents: 5 feet per second (FPS)

    • Water Depth 3 ft to 50 ft (curtain height should be at least one foot less than water depth)

  • Coastal or Marine Construction, DOT Road and Bridge Construction, Dredging, Mining, Pile Driving

  • The permeable skirt is made of a geo-textile fabric that allows water to flow through the curtain while still filtering any suspended silt or sediment.

  • These silt curtains are made with the same PVC fabric that is used for the floats. This fabric does not allow water to pass through, creating a barrier that fully blocks the water and any silt or sediment that may be suspended in the water.

    • Constructed using 100% RF Welds

    • Universal aluminum end connector plates at the top and bottom, with reinforced end seams with grommets between the two connector plates

    • Flotation segments are 3 ft long for superior wave conformity and ease of handling and storage

    • Flotation chambers individually sealed with RF Welds

    • Custom heights available – floatation sized to support skirt height and conditions

    • Skirt height can be tapered to conform to the bottom profile of the body of water

    • Ballast chain for strength and stability

    • Typically made with fabric color of International Orange, with other colors available via special order
