Company information
Our division is engaged in repair work, reinforcement work, and repair design. Due to recent changes in the natural environment, the durability of structures has significantly deteriorated, leading to an increase in the number of structures requiring repairs. Additionally, with changes in seismic standards, there has been a rapid increase in reinforcement work for existing structures. The era is shifting from scrap and build to maintenance.
