ABSTRACT:
A predrawn net particularly for geotechnical use including an initial component that forms a first and a second layers that are respectively constituted by a first set of mutually substantially parallel filaments and by a second set of mutually substantially parallel filaments that lie transversely with respect to the filaments of the first set, so as to form a plurality of mutual joints. The filaments of the two sets mutually interpenetrate in the joints over a thickness that is less than 50% of one of the layers. The initial component is more than 8 mm thick. The filaments of at least one of the sets are drawn in the direction defined by the respective set of filaments so that the stretching action passes through the joints without substantially affecting the filaments of the other one of the sets.
