Permeable Silt Curtain Design

The design of the permeable silt and turbidity curtains includes several standard components, as well as permeable filter panels to increase the filtering ability of the curtain. Standard components of this curtain include the following:

  • Top Flotation Device
  • Marine Grade Bottom Ballast Chain
  • Exterior PVC Fabric
  • Request a Quote
  • Geotextile Filter Panel
  • (Optional: Tension Cables Dependant on Water Flow)

The construction of this permeable curtain provides several components that allow for effective filtration of silt and turbidity in your location. This provides a way for water to flow through your curtain while still preventing silt and turbidity from moving to undesirable locations.


Permeable Curtain Components

In order to filter materials in your location, included into each section of your silt curtain is a geotextile filter panel. Similar to other geotextiles, this filter panel is designed to keep sediment and silt on one side of the curtain while still allowing for water to flow through the curtain. This can be especially useful in locations dealing with high water flows as the geotextile helps relieve pressure on the curtain.


Silt Curtains & Water Conditions

Regardless of your whether you require a permeable or impermeable curtain, there are several conditions you will need to take into consideration to ensure that the best curtain type is used in your location. Conditions you will need to consider include the following:

  • Water Current/Flow Rate
  • Wave Conditions including Wave Height & Frequency
  • Tidal Factors
  • Wind or Site Conditions
  • Amount of Silt & Turbidity Needing to be Contained.

For permeable filter options, panels are usually added to the Type 2 and Type 3 curtains for moving water areas. If you are unsure of which option would be best for your location, please do not hesitate to contact us and we would be happy to help determine the right option for your location.
