Report on Participation in the "Annual Forum 2025" of the Defense Facilities Society
On February 12, 2025 (Wednesday), at Hotel Grand Hill Chiyoda, Protech Engineering exhibited at the "Annual Forum 2025" organized by the Japan Society of Civil Engineers. During the event, we would like to express our sincere gratitude to the many visitors who came to our exhibition booth. At the booth, we were able to showcase the features, construction methods, and achievements of our products using models, panels, and catalogs. As the time was short, there may have been things we were unable to convey and areas where we fell short. If you have any questions or require any materials, please do not hesitate to contact us. ◆Exhibited Products◆ - Rockfall Protection Reinforced Soil Wall / Geo-Lock Wall (Model Display)
