MCN Co., Ltd. will be exhibiting at the "7th International Construction and Surveying Expo (CSPI-EXPO2025)" held at Makuhari Messe. Cutting-edge products, technologies, and services from the evolving industries of construction machinery, heavy equipment, attachments, construction DX, and i-Construction will be gathered in one place. This exhibition is one of the largest in Japan, where professionals from the construction and surveying industries come together for information gathering and problem-solving discussions. We plan to showcase materials related to disaster recovery spraying systems, mortar repairs, and electric dust collectors. We would be delighted if you could visit our booth when you come to the venue.

Thank you all for your continued support. This time, I would like to introduce a construction case of a small cross-section tunnel. Below are the construction conditions: 1. Construction cannot be done with large machinery. 2. Material delivery is difficult. 3. There are concerns about noise issues. Construction was carried out under these conditions. The materials were loaded onto a small truck and sprayed at our small plant. If you have any issues with spraying in tunnels or anything else, please contact the MCM Hokuriku Center. Thank you very much.

MCN Corporation handles electric dust collectors for tunnel construction, shotcrete mortar application systems for TBMs, rapid shotcrete systems for small cross-sections, and other civil engineering-related materials, machinery systems, and consumables. The most frequently rented equipment from our company is machinery for mortar spraying. In this news update, we have included examples of spraying from a project we were previously involved in. In the future, we plan to share other construction examples and features of electric dust collectors, so if you have any questions about our products, please feel free to contact us. Thank you for reading.
