Turbidity Barrier Specifications

American Marine, a division of Elastec in Cocoa, Florida, has been manufacturing turbidity barriers since 1967. Also referred to as silt curtains, screens or turbidity curtains, their purpose is to minimize the migration of sediment from a marine construction or dredging project to protect sensitive habitats. Built with the latest geosynthetic material technology, Elastec’s American Marine was an early pioneer in turbidity barrier development and invented a universal connector system which is still an industry standard today. Standard curtain specifications are available. Elastec can also custom fabricate turbidity barriers to keep debris and sediment accumulation under control.
