Due to their very good flexibility, mechanically bonded nonwovens are especially suited because they allow a robust handling due to the optimal stress/strain behaviour and adjust well to the subgrade. Moreover, the flexible system deforms optimally during wave impact absorbing the impacting forces. The three-dimensional needle-punched nonwovens are furthermore particularly abrasion-resistant.


In geotechnology and hydraulic engineering, earth materials in particular are «packed» in flexible tubes, sacks and containers. Here geosynthetics perform separating, filtering, protecting and/or reinforcing functions, depending on the type of application involved. The materials used include nonwovens, wovens, geogrids and composites.
