Earthworks in marine environments such as lakes & waterways require special care to ensure the protection of the surrounding ecosystem. Waterbourne sediments can be quite damaging to marine life, and containing these sediments to a confined area is a must. This is exactly the purpose of Silt Curtains, or as we call them - EnviroSieve Turbidity Curtains.
A great example of the use of Silt Curtains by HEB when undertaking a long section of roadworks directly next to a large pond of water - and the results were outstanding, really showcasing the power of Turbidity Curtains.
Cesspit Filter Bags & Dams are used as a filter for stormwater drains & cesspits. Both are used to achieve the same result, although the Dams are a fast and easy solution which can be quickly moved, cleaned and reused. Filter Bags on the other hand, provide a similar result but without the integral interceptor dams and are typically used in conjunction with silt socks, and can also be reused.
We have created an interactive 3D model for Cesspit Filter Bags, showing the installation steps, and the placement of Silt Socks beforehand, slowing water viscosity and allowing for sediment dropout.
