Coastal protection
Waves and wind generated in marine conditions have the most severe eroding effect on coastlines and structures built by humans. Rock revetment is the most traditional way of protecting coastlines against erosion.
Traditionally, rock revetments are made up of a granular filter progressing from fine granules to coarse granules that build up a natural filter. This filter prevents sand from being washed away from behind the rock revetment and assures the stability of the structure. Geotextiles are able to replace up to 1 m of this granular filter which makes them a very economical and ecological alternative to granular filters. We have a broad range of geotextiles to answer to individual project needs. From geotextiles that are able to absorb enough energy from falling rocks, to fabrics with a water permeability that is in line with the permeability of the soil at the site. Also the opening size is taken into account to prevent washing out, clogging, etc.
Constant wave attack and high velocity currents may result in the collapse of these thick filters and instability of the revetment.
Heavy nonwoven and woven Enka-Tex fabrics can be used as filter layers with proven performance in preventing instability of rock revetments.
