Sizes and Installation for the Type 1 Barrier
Question: I am looking for turbidity curtains that can be placed in fairly calm waters in a creek to control the sediment while we do some work. What sizes do they come in? How would I assemble it?
Answer: The Type 1 Floating Silt Barrier is designed specifically for calm water applications. They are often used for marine construction jobs, roadside projects or in calm lakes and ponds where little wind, waves or water velocity is present.
Standard lengths for the Type 1 turbidity barrier are in sections that either 50 or 100 feet long and 5 feet wide. However, the silt barrier is an extremely versatile product that is designed to meet your exact specifications. Please don't hesitate to send us your specific curtain depths, heights or requirements.
Turbidity Curtain Design:
The turbidity curtain is a highly visible and reliable product that has been used many sediment filtering and collection jobs. Typically specifications include:
- 18 oz. Vinyl Fabric (although higher strengths and different fabrics are available for tougher jobs)
- Section ends are double seamed for high strength
- Floatation size is typically marine quality at 6" (other sizes depending on the depth of your barrier)
For installation of a type 1 barrier, their is basically a two step process that is recommended.
- Step 1: Attach the chain on section 1 of the barrier to the chain or ring of section 2. This can be done through use of a shackle or snap hook.
- Step 2: Using rope or heavy zip ties, tie one grommet eye to the aligned eye of its mating section. This should be done for the entire barrier length.
When setting up the barrier, it is always recommend that the barrier remained tied and reefed up until it has been properly towed to its location. Curtains typically come with reefing lines already in place so it is usually suggested that these lines not be cut until after proper installation. If these lines are no longer in place, the curtain can be curled up to the flotation by tying a reefing line around the flotation log.
