Choosing the Right Silt Barrier for Your Location

permeable silt barriersChoosing the right turbidity barrier for your location will depend on several factors. Any time you are considering using a barrier for your location, we advise customers to review the following conditions on their location:

Water Conditions

  • How fast is the water moving in your location?
  • Are there waves?
  • How high are the waves and how frequent?
  • What tides are present?

Site Conditions

  • In what type of project will this barrier be used?
  • What is the duration of the project?
  • What type of material will be contained?
  • What is the depth of your water?
  • Is there wind? If so, what is the wind speed?

While silt barriers come in standard lengths and depths, we welcome custom sizes! If you have a project with specific requirements, please call us or send us a form highlighting details about your project. Curtains have been made for shallow water application and as deep as 100 feet.
