      Floating Silt Curtain

      Floating silt curtain is a BMP designed to restrict the flow of sediment-laden storm water runoff from a construction site, to keep it contained in a limited area and allow the sediment to settle out before being carried into adjacent or joining watercourses. Agassiz Seed & Supply has floating silt curtain available for still water or moving water applications with a variety of curtain lengths to facilitate the water depth on your project.
