Standard, the silt screens are manufactured in 25 to 30-metre length sections, whereby both the floating part on top and the silt boom around the bottom are custom-built to suit the nature of the works and the location. In doing so, the length of the underwater boom is adapted to the bed profile of the body of water in the operating area. As a result, in the case of backfilling operations, the sediments will sink to the sea or river bed without being evacuated. In the case of dredging operations and earthworks, silt and sand will not be displaced and remain locked inside the operating area.
For complex and challenging locations, Ecocoast has digital mathematical models which factor in the water flow, the waves, the nature of the works and obviously the kinds of sludge, the sediments, the geology, etc. in order to arrive at a custom-made solution. Ecocoast draws on its longstanding experience to produce a preliminary design which is virtually tested and optimised before it gets to the installation stage. No trial & error for complex or challenging assignments, but a solution that is engineered ahead of time and is included as part of the supply of the silt screens.
