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.
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.
