While (permeable) geotextile silt screen curtains are a good option for sites that require a permeable calm water barrier, many sites require an impermeable curtain in order to meet site requirements. Impermeable silt curtains should be used any time you are dealing with longer term applications, DOT requirements, or significant silt requirements. Some benefits of the standard silt curtains include:

  • Impermeable PVC Material
  • Increased Strength
  • Allows Silt Enough Time to Settle
  • Contractor or DOT Models

Permeable floating silt screen is available in Type 1, Type 2 and Type 3 models, with options to accommodate project sites with stronger currents and wind exposure.
