Many coastal areas are exposed to processes of erosion that change their morphology, often causing entire sections of land above and below the water level to disappear. Changes are due to the drifting movement of sediments (in the longitudinal or transverse direction), caused by wave motion and currents. Measures adopted to conserve the coastal environment are designed either to attenuate the impact of wave motion, or to intercept and contain the solids physically displaced by the water. In the former case, submerged barriers, breakwaters, are laid at a distance from and parallel with the shoreline, to cushion the violence of the waves; in the latter, linear structures — groynes — are erected transversely to the coastline, so as to intercept the currents and prevent the drift of sediments out to sea.
The SINTEXTUBE range of tubular textile filters, made to measure by GEOSINTEX, provide a valid alternative to structures fashioned with cyclopean boulders or concrete blocks, both for submerged breakwaters and as the core element of groynes. Textile mattresses are filled with sand available directly on site, dredged from the seabed, so that there is no quarrying and transport of aggregates involved, which in turn means minimal impact on the environment.
SINTEXTUBE filters can also be used to fashion artificial dunes designed to protect structures or buildings in close proximity to coastlines, or incorporated into environmental engineering projects.
There is also a place in these installation for SANDBAGS, smaller textile structures that are suitable for use as ballast or in conjunction with SINTEXTUBE filters, as fillers and interconnecting pieces.
