In the Huelva region, a geotechnical project covering 15,000 square meters was completed. The selected geotextile, Geotesan NT 25, is composed of 100% polypropylene virgin fibers, manufactured through a needlepunch process and subsequent thermofusion for enhanced mechanical strength. Geotexan’s geotextiles, designed for separation, filtration, drainage, reinforcement, and protection, proved instrumental in the success of this project, highlighting the effectiveness of their advanced materials.
