River Turbidity Curtain

How to Install a Barrier

Installing turbidity curtain in riverQ: Hi. I am looking for a river turbidity curtain that I can place to work ten feet off the shores edge. I have never used one and I would like to know how to install it and how to seal it at the bottom. My river moves pretty rapidly so I would probably need a type 3 right?

A: Thank you for contacting us! In general, if your water conditions are above 1.5 knots or you have waves higher than 36 inches, you would want to use the Type 3 Turbidity Curtain. The type 3 turbidity barrier uses the heaviest materials so can handle more demanding conditions. It can also allow you to use the turbidity curtain for multiple deployments.

When considering the type of turbidity barrier that will work best in your location, you will want to additionally consider the type of debris that will be maintained, wind conditions, length of you project, and other factors that may influence the river turbidity curtain.

You have mentioned that you would like to know how the turbidity barrier seals to the ground. Typically, a turbidity barrier should not seal to the bottom of the ground but should instead sit about one foot above the bottom of your river. If you install the barrier to the bottom of your location, it causes a tremendous amount of pressure to build up against the barrier and prevents it from functioning properly.

Installation of a Silt Barrier

Installing turbidity curtainTo install your river turbidity curtain, you will first want to unload the barrier from the truck. In order to make this process easier, it is best not to untie the vinyl straps until your barrier is in the position you require. You should then place each bundle about 15 to 20 inches apart from each other in places where there is an adequate amount of room to work. Once the turbidity curtain is in position, untie the straps. The next step is to attach the bottom chain of the silt curtain to your barrier. This chain can be attached by means of a shackle or snap hook. You will need to attach the chain for section 1 to the chain or ring of section 2. After this, you will need to slide the aluminum extrusion end connections together and insert the toggle pin.

After this has been completed, the next step is to align the grommet eyes on each section of the turbidity curtain. You will need to align the grommet eye of one section to the grommet eye of its adjacent section. These eyes should then by tied together by means of rope ties or heavy-duty zip ties. The should continue for the entire length of the barrier. After this has been completed, take the reefed up curtain and tow it out into its proper location.
