Ecocoast reinforcements in geotextiles are used in bank reinforcements, an efficient means of combating erosion, as breakwaters or floor barriers, weir and dyke elevations or in the case of land reclamation works and the building of all manner of (temporary) maritime constructions. Both in freshwater in the interior and in saltwater along the coast and in ports, they bring sustainable added value.

Numerous successful installations have demonstrated Ecocoast’s know-how and experience with the use of geosynthetic reinforcements. The application, location and environmental parameters combine to determine the most efficient and most sustainable solution. In all cases, a bespoke design is produced, tailored to the customer’s intended purpose and checked by way of a hydro-dynamic mathematical model devised by Ecocoast.

Ecobags are more than just plain old sandbags. They are made from a sustainable geotextile and are virtually indestructible. The construction adapts to the bedding, with which it goes on to make up a whole. Especially when using the geotextile Ecotubes, completely conjoined constructions are created that will withstand the most extreme conditions.

Ecocoast’s Ecobags and Ecotubes are also used for dewatering purposes, to separate mud and sludge, whereby the water is naturally drained from the geotextile.

Ecocoast silt screens are mainly used in hydraulic engineering works where sand, sludge and sediments need to be kept separate. Dredging works, deepening basins, sluices and drainage, raising the sea or river bed or backfilling operations often come with a lot of earth movement which means they cause mud, sludge or contamination or sludge (silt), which may or may not be polluted.

By putting in place the Ecocoast silt screens in the shape of large water-permeable, albeit not silt-permeable booms, the operating area remains separate from the other areas to be preserved. The silt screens consist of a floating barrier that stops foam, sludge or other floating contaminations above water. In addition to stopping the floating mass on the surface, below the waterline a water-permeable boom with micro pores stops the floating material, such as fine sand and sediments. Water is allowed to pass through the screen but the sediments float up against the screen before sinking to the sea or river bed. These silt curtains or silt screens allow for operating areas to be completely segregated.

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.

Ecocoast’s oil containment booms are used in hydraulic engineering works involving ‘heavy equipment’ and a real risk of oil leaks. As a preventive oil containment boom to cordon off dredging operations, bore holes, earthworks and such like, this floating oil containment barrier will contain the oil pollution. Even in case of comparatively high waves, the oil remains inside the barriers, after which it can be pumped up or absorbed.

The oil containment boom is made up of 20 to 30-metre sections and comes in heights of up to 1.5 metres. The booms are linked together using dedicated ASTM end plates. They are easily fitted, secured into place and even detached in water. Once chained together, the different length sections are fitted with ground anchors or ballasts to keep them in the desired shape and position around the area where the works are being carried out. The material from which the ‘oil containment booms’ are made is resistant to oil and chemicals and contains UV stabilisers. In doing so, the boom is used to create a closed loop bellows or tube which, thanks to the integrated floats, acts like an autonomous float.

Ecocoast’s oil containment booms can also be used to stop floating debris or rubble in port or quayside works, or as a temporary boom against non-native species, blue-green algae or other aquatic plants.
