Type 1 Permeable Silt Screen
Geotextile Curtain for Filtering Sediment
The Type 1 Geotextile Silt Screen is an all permeable curtain that provides both containment and filtration in calm water areas. Made from an eight ounce (8 oz.) nonwoven geotextile, our curtains are often used in areas with mild conditions.
- Calm Water Areas
- Shallow Water
- Temporary Silt Containment Requirements
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
While 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.
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
Type 1 Silt Screen Curtain Additional Models
For certain locations, having a more robust design is required in order to effectively keep silt contained. For these areas, standard impermeable Type 1 silt curtains (18 oz. PVC) are also available.
