How to Install a Turbidity Curtain

Silt Barrier Installation

installation of turbidity curtainQuestion: I need to know how to install a turbidity curtain. I am looking for a silt barrier or turbidity curtain (not sure if they are the same) and would like to know how much would be involved with the installation? I believe that I will need a type 2 silt barrier with a medium velocity.

Answer: The turbidity curtain (known by various names as either a silt barrier, turbidity barrier, or even silt curtain) is a device used to control and contain silt or turbidity during construction, dredging, and various other activities. These barriers will typically feature an impermeable design that allows particles to be contained within a site.

Regardless of their name, turbidity barriers are used in various operations across the country including some of the following:

  • Dock Construction
  • Pile Driving
  • Dredging
 
  • Marine Area Construction
  • Construction Along Lakes, Ponds, Shores

Installation Procedure

  1. Lay Out Your Silt/Turbidity Barrier: Sections for these barrier typically come in lengths of either 100 or 50 feet. These sections should be laid out on your workplace or shoreline and spaced at approximately 15 to 20 inches apart.

  2. Cut the Vinyl Bundle Straps

  3. silt barrierAttach the Bottom Chain Ballast: On the bottom of the barrier you should find a chain ballast which has been secured to a stainless steel stress place. On one end of a barrier section you should find a snap hook and on the other end you should find
    steel ring. Sections can be joined by connecting the snap hook from one section to
    the steel ring of the adjacent section.

  4. Slide Connectors Together: On the Type 2 or Type 3 barrier you will typically find aluminum connectors. These connectors should slide together and can be secured with a toggle pin.

  5. Connect Grommets: From here, upper portions of the barrier can then be connected through its grommet eyes. This is achieved through the use of rope or zip ties.

  6. Repeat Procedure for Entire Length of Barrier

  7. turbidity curtain installationTie Bottom Skirt Around Flotation: After the silt barrier is completely connected, the bottom curtain should be reefed or rolled up around the flotation log and then tied. This makes the barrier easier to work with during installation.

  8. Tow the Barrier into Desired Position

  9. Untie the Reefing Lines and installation should be complete.
