Silt Curtain Turbidity barrier with PET Woven Geotextile Skirt
SILT CURTAIN/TURBIDITY BARRIER
Why do you need Silt Curtain?
Researches of marine life and organisms have found that fine silt particles can affect the living conditions of sea or river creatures and its environment. So today's environmental protection policies require companies and Individuals to take all reasonable precautions to prevent sediment contamination of waterways when job is performed.
When construction is taking place immediately adjacent to a waterway, such as a Canal
development or construction of a bridge, land reclamation, wharf or jetty, floating silt curtain
will be applied to confine sediment and prevent dispersal and contamination of the water body.
What is Silt Curtain?
Pioneer silt curtains are flexible sediment control barriers designed to prevent the spread of silt and sediment in lakes and other water bodies when job is being performed in water, or on or near the shoreline. It’s constructed of permeable fabric or non-permeable textile material. The Turbidity Curtain is suspended vertically in the water with a flotation material enclosed in the top pocket and a ballast chain enclosed in the lower pocket.
Standard and custom fabricated size are available with a variety of fabric options, floatation sizes, loading bearings, ballast members, connectors and curtain depths and lengths to suit your project need in Pioneer.
How to choose proper Silt Curtain?
Choosing the right Silt Curtain (turbidity barrier) for your location is highly dependent on several different site conditions. When considering the right option, we typically urge customers to consider various job site factors and conditions, including water flow (current speed), waves (height, frequency), wind (speed, direction), job type, and job duration. If you have any additional site-specific requirements, please feel free to let us know these conditions as well. Typical conditions and components can be found below:
