Standard silt curtains are surface-suspended — they extend downward but leave a gap between the curtain’s lower edge and the seafloor. In any tidal or current environment, water flow takes the path of least resistance: through that bottom gap. Sediment-laden water flows directly under the curtain and into sensitive benthic habitat. For seagrass, oyster beds, and coral, that turbidity exposure is a permit violation and an ecological impact. TITAN Boom™ seals the gap at the seafloor, closing the pathway standard curtains leave open.
