Geotextile curtains are constructed with either a 4" or 6" float and have a bottom skirt ranging anywhere from 3' to 10'. Silt screen curtains are intended for short term projects.

When to Use an Impermeable Silt Curtain

Impermable 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
