Type 2 Turbidity Curtain
FAQ: What are the standard dimensions for Type 2 Turbidity Curtain?
Question: Hello. I am looking for a Type 2 Turbidity Curtain that has the dimensions of 50 feet long by 5 feet wide. Do you have barriers in this length? If so, how would I install the barrier?
Answer: Thank you for contacting us! The Type 2 Silt Barrier is a widely used barrier designed to control sediment and turbidity in water areas with mild conditions, such as rivers, lakes, ponds and shorelines. This barrier is available in a standard length of 50 feet, as you requested, as well as sections that are 100 feet in length.
Depth for these silt barriers is designed based on the depth of your specific water area. Available depths include sizes anywhere from 3 to 100 feet. Typically barriers should not touch the bottom of your water area and should sit about one foot above the floor. This helps to keep your barrier from accumulating too much pressure during containment.
This silt barrier is designed for high strength control and is typically constructed using a flotation device, skirt, and bottom chain. This construction offers the appropriate blend of floating and sinking, so you barrier can form a solid area of containment both above and below the surface of the water.
Type 2 barriers are made in both a heavy duty and economy model. Both models are typically designed to meet DOT state regulations so you can safely control silt and turbidity in your area.
Standard features you might find on either of these barriers include:
- Marine Grade Flotation Device (measures anywhere from six to twelve inches (6" to 12") depending on the depth of your curtain)
- PVC Skirt & Barrier Fabric
- Universal Slide Connectors
- Bolt Rope Reinforced Grommet Section Ties
- Steel Ballast Chain
Turbidity Curtain Installation
Installation of a type 2 turbidity curtain may vary depending on your specific site or area conditions, however, barriers can typically be installed using the three part procedure shown below:
- Connect sections together by attaching a shackle or snap hook from one section of barrier to the chain or ring of another barrier.
- Slide together aluminum end connectors and insert the toggle pin.
- Align grommet eye from one section of the barrier to the grommet eye of the adjacent section. Using rope or heavy-duty zip ties, secure these sections together through aligned grommet eyes. Repeat for the entire skirt depth.
Once these steps have been completed, the type 2 turbidity curtain can be safely towed to its required location. When you receive your silt barrier, the barrier should be furled or reefed up to the flotation so that the barrier is compact and easy to manage. It is typically recommended that the ties used to keep these barriers together should not be cut or untied. Keeping this barrier in it original curled position can make the turbidity curtain easier to maintain, tow, and maneuver into its required position.
