American Marine, a division of Elastec in Cocoa, Florida, has been manufacturing silt barriers since 1967. Also referred to as silt curtains, screens or turbidity barriers, their purpose is to minimize the migration of silt and 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 silt barrier development and invented a universal connector system which is still an industry standard today. Standard silt barrier specifications are available. Elastec can also custom fabricate silt barriers to keep debris and sediment accumulation under control.
