Silt curtains are used to control silt when working in low flow or standing water applications. Silt curtains prevent particulate materials from leaving the immediate area of construction in the water, protect aquatic environments, and help from costly environmental cleanup work and liability from environmental damage. Standard FSC units are available in nominal heights of 7ft, 13 ft and 19 ft (2.1m, 4.0m, 5.8m) but custom curtains can be made to accommodate any water depth.
For heavier duty or higher flow applications, Layfield provided Turbidity Curtain
Turbidity curtains are deployed in areas where sediment discharge to a stream is unavoidable. They are commonly used within a water body to protect against sediment migration from construction areas into the rest of the water body. Our Turbidity Curtains are designed to effectively deflect and contain sediment within a limited area and to provide sufficient retention time for the sediment particles to settle out. Curtains are suspended vertically in a body of water with floats at the top and a ballast chain in the bottom to hold the curtain in a vertical position. They can be used in standing or slow moving water or in rivers with flow rates of up to 5ft/second.
