  • What is a turbidity curtain?

    A turbidity curtain is used to contain turbidity (sediment and salt) that is stirred up by construction activities taking place in or near bodies of water, dredging operations and rainwater runoff.

    What are common names for turbidity curtains? 

    Turbidity curtains are commonly referred to as a turbidity barrier, silt barrier or a silt curtain.

    Do you make your own turbidity curtains and booms? 

    Yes! We manufacture all silt curtains, booms, and baffles in our facility located in Humble, Texas.

    What is the cost of a turbidity curtain? 

    Costs are always dependent on the size, application, and duration of the turbidity curtain. We recommend contacting one of our sales representatives, so that they can explain our pricing structure and help you find the best curtain, baffle, or boom for your project.

    Does ABASCO provide installation services? 

    Yes. We can provide full installation services for turbidity curtains, booms, and baffles.

    How often should I inspect my turbidity curtain? 

    If your turbidity curtain is exposed to an area with high marine traffic, construction activities, should be inspected daily. Calmer environments can have inspections every several weeks. In the chance of extreme weather, curtains should be removed in advance to avoid risk of damage.

    What are common lengths for turbidity curtains? 

    Turbidity curtains are usually made in lengths of 25, 50 or 100 feet. ABASCO can create custom turbidity curtains with varying lengths.

    What regulations do you meet? 

    We meet regulations and requirements of the Clean Water Act, National Pollution Discharge Elimination System (NPDES), and any state (DOT) and local regulations.

    How many anchors do I need for my turbidity curtain? 

    ABASCO's representatives analyze several factors such as anchor loads, wind, bottom conditions and current directions to determine the amount and placement of anchors needed because it depends on each project's environment.

    Should turbidity curtains touch the floor of the containment area? 

    Usually you want to keep the curtain 1’ off the bottom during Low Mean Tide (LMT). If you need the curtain to touch the bottom it may need to be modified or upgraded.

    What are the options for turbidity curtains if the depth of water is different across the containment area? 

    ABASCO can provide curtains with customized tapered bottoms for adjustment and/or furling lines which can adjust depth while in operation.

    How do I know if I need a boom or a curtain? 

    Containment Boom is usually used to capture items at the surface, typically to be removed from the water such as oil and trash. Curtains are used to isolate an area, typically allowing sediment to settle in a controlled environment.

    What factors should be considered in choosing a turbidity curtain? 

    Multiple variables can determine which curtain you need such as depth, current, wave height and wind conditions being the primary factors. They are also regulated by government agencies or the contractual requirements.

    What are some considerations for selecting an anchor system on a turbidity curtain or boom? 

    Multiple variables will determine anchoring requirements just as they are needed to determine the type of curtain but the layout and potential curtain load will have the largest influence.

    What's the difference between a tow bridle and an anchor system? 

    Anchor Systems are used to secure the curtain along the perimeter. Tow Bridles can secure the ends and for deployment/towing purposes.
