Silt Conditions and Factors to Consider
Any time you are looking to use one of our 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? Can I reuse a barrier?
- Wind: Is there wind? What is the speed and/or direction?

Choosing the Right Turbidity Curtain
Regardless of model, the most common floating silt curtain design involves the use of a top flotation, impermeable skirt, and bottom ballast chain. When the barrier needs to accommodate waves or currents, a tension cable will be added to the top section of the curtain. This is used to control the spread of materials and is 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/DOT Curtains are most commonly used for construction, DOT, and short-term projects. Models include:
For longer term projects, GEI Works offers several heavy duty curtains that can withstand extended use, heavy loads, and higher flows. Models include:
