東亜グラウト工業 Company Profile

A variety of construction methods and skilled techniques! A pioneer in infrastructure development.

Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."

Business Activities

■Improvement Group Contributing to the development of a reliable social infrastructure through "ground improvement work," which plays an active role in various underground construction scenarios, and "structural maintenance work," which involves the upkeep of existing structures. ■Disaster Prevention Group Protecting lives and property from natural disasters such as falling rocks, landslides, debris flows, and avalanches using specialized techniques, contributing to the creation of a safe and livable country. ■Pipeline Group Investigating and diagnosing lifelines (pipelines) in the era of seismic retrofitting and maintenance, performing repairs and renovations with a wide variety of construction methods, and carrying out preventive maintenance and restoration of functionality.
