Staked Turbidity Barrier
Turbidity Barriers are designed to keep silt, sediments and debris from migrating off a site into water. Federal and state regulations require the debris to be contained within the work area. There is a considerable difference between turbidity barriers. Off the shelf turbidity barriers will provide some protection but generally are inadequate for most applications. Some of the factors that need to be considered are:
- Size of Sediments
- Water flow velocity
- Deflection angle relative to current
- Debris likely to be encountered
- USCG Requirements
- Length of deployment
- Water Depth
Siltdam Turbidity Barriers can accommodate a wide variety of wind, sea, and current conditions. It is an excellent barrier for dredge and dragline operations in open water where increased flotation, depths and tensile strengths are required.
Siltdam standard turbidity barriers offer an additional benefit of debris and oil containment at water line. 22 oz PVC oil boom fabric is heat sealed around a series of closed cell expanded polyethylene logs to create a watertight compartment and greater strength. The logs are resilient in nature and capable of being subject to rough service during deployment and recovery below the float compartment a skirt is installed to the required depth. The skirt can be manufactured from a number of different materials depending upon the application and jobsite conditions. For example monofilament skirts have higher flow rates for fast current environments. Non-woven geotextile skirts are used for fine sediments or hydrocarbon remediation. While impermeable skirts are used when hazardous materials are present. After the skirt is attached the turbidity barrier is then ballasted continually along the bottom using a galvanized steel chain.
If you are looking for a high quality, durable, and sturdy barrier then Siltdam Turbidity Barrier is what you need. They are typically available in 50 or 100 Foot sections. Please give us a call. We can customize any barrier to meet specifications and jobsite conditions. We welcome the opportunity to work with you.
Anchor Systemstop of page
For very high flow or tidal current it is sometimes necessary to use diver-installed anchors such as Manta Ray or Platipus anchor systems. There are many variables to consider when deploying anchor systems. Knowledge of the current flow, prevailing winds, bottom composition and depth of water can help to focus the design of a proper anchoring system. Contact us with your site specifics to discuss if these systems are necessary for your application.
Staked Turbidity Barrier top of page
Staked Turbidity Barrier is often used as an alternative to floating barrier in very shallow water applications. Similar in design to heavy duty silt fence, staked turbidity barrier is shipped as a kit that includes a filter skirt with pockets for the metal posts and ties to hold the skirt in place. Post spacing is predicated upon flow velocity. Installation is simple. All you need is a posy driver, two pairs of waders and two workers. When properly installed staked turbidity barrier is a cost effective alternative to floating turbidity barrier.
