Abstract
The plastic material net structure, particularly useful for geotechnical applications, has a plurality of holes uniformly arranged in rows and columns. The sheet further comprises portions which are elongated in the stretch direction, are mutually separated by the holes and have a predominance of molecules orientated in the stretch direction. The elongated portions extend from node elements which have a plurality of non-orientated molecules. The node elements are mutually joined by non-oriented transverse portions which extend between said holes in a direction which is substantially perpendicular to the elongated portions. The node elements have a thickness which is greater than the thickness of the transverse portions and of the elongated portions.
