For more than 20 years TENAX has decided to protect its own inventions with patents, creating a Patent and Trademark Department. This operates within the wider operating area of the Legal Department. This decision means that TENAX can continue to develop technological innovations and devote itself to the research, consolidation and protection of its achievements. Among TENAX's major inventions are: a production process for "squaring" rhomboidal meshes, the manufacture of extrusion heads for laminar nets, three-dimensional cellular structures to counter earth erosion and the application of nets for drainage. In the last ten years, TENAX has developed new products and applications, especially in the geotechnical field, and obtained the relevant patent protection.
