Turbidity and Silt Curtains

The Turbidity Curtain is an economical option for any location where silt and turbidity control is required. Often used in control floating materials in calm water, moving water and fast water areas, these curtains are one of the most economical ways to keep your solids under control for the duration of your project. In order to accommodate different water conditions, these barriers are made in three standard models: Type 1, Type 2 and Type 3 Turbidity Curtains.

Choosing the Right Turbidity Curtain

silt curtainRegardless of model, the most common floating silt curtain design involves the use of a top flotation device, impermeable skirt and bottom ballast chain. When the barrier will need to be accommodating waves or currents, a tension cable will be added to the top section of the curtain to control the spread of materials. Tension members will be most commonly found on the Type 2 and Type 3 models.

Choosing the right model for your location is dependant on several different factors including project type and duration. In general, turbidity curtains are typically classified in either Contractor or Project/HD models.

Contractor Curtains

Contractor/DOT Curtains are most commonly used for construction, DOT and short term projects. Models include:

  • Type 1 Contractor
  • Type 1 Economy
  • Type 1 DOT
  • Type 2 Contractor
  • Type 2 DOT
  • Type 3 DOT

Project Curtains

For longer term projects, Granite Environmental offers several heavy duty curtains that can withstand extended use, heavy loads and higher flows. Models include:

  • Type 2 Heavy Duty
  • Type 2 Heady Duty Permeable
  • Type 3 Heavy Duty
  • Type 3 Heavy Duty Permeable

Silt Conditions & Factors to Consider

Any time you are looking to use one of silt control curtains, we typically urge customers to take the following factors into consideration prior to choosing their silt curtain style:

  • Water Conditions:

    • Water Velocity: How fast is the water moving?
    • Waves: Are there waves? How high/often do they occur?
    • Tides: Are there tides?

  • Site Conditions:

    • Particles: What type of silt, turbidity or sediment are you trying to contain? Is it contaminated?
    • Project: What type of project is this barrier for? How long will the project last?
    • Wind: Is there wind? What is the speed and/or direction?
