Type 1 DOT Silt Curtain

A DOT Type 1 turbidity curtain is a floating silt barrier purpose-built for state highway and transportation projects in calm or protected waters. It creates a continuous perimeter around bridge footings, culvert replacements, shoreline grading and other roadside construction so disturbed soil stays inside the work zone until sediment settles. Rated for ponds, lakes, canals and roadside swales with minimal current or wave energy, the curtain’s impermeable fabric, foam flotation and bottom ballast keep the skirt upright while rugged connectors let crews link multiple sections for long runs.

Type 1 Contractor Silt Curtain

The contractor version of a Type 1 turbidity curtain is a light-duty, budget-focused silt barrier designed for jobs that do not require Department of Transportation certification. It uses a lighter fabric and smaller flotation components, making each panel easier to lift, transport, and install than its DOT counterpart. This reduced weight suits short-duration work in very calm water such as pond dredging, shoreline repairs, utility trenching, and other small construction tasks where minimal sediment is expected.

Type 1 Permeable Silt Curtain

A permeable Type 1 turbidity curtain often called a geotextile silt screen or permeable silt curtain is designed for calm-water projects that need both containment and filtration. The skirt is sewn from nonwoven geotextile that lets clean water pass while capturing suspended particles; this flow-through fabric eases pressure on the barrier and keeps it stable in mild conditions. Contractors use the permeable curtain for short-term dredging, habitat restoration, ditch or canal maintenance, and other still-water work where limited water exchange improves oxygen levels and meets permit requirements.
