We will investigate the soundness of the overlay concrete, the condition of the foundation ground, and the presence of voids, among other factors.
At Kyoa Development, we conduct maintenance management operations such as tunnel and bridge inspections. Since the conditions (backfill, foundation ground, concrete thickness, structure, etc.) vary for each target structure, experience and advanced know-how are required. Our company proposes maintenance management methods that achieve maximum effectiveness at minimal cost by utilizing our achievements in soil investigations and various exploration and testing techniques. 【Business Content】 ■ Tunnel Maintenance Management ・Visual and sound inspections ・Radar ■ Bridge Inspections ・Touch, visual, and sound inspections *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Koa Development was established in 1953 (Showa 28), and thanks to your support, we have surpassed our 60th anniversary, for which we are sincerely grateful. Our company started as a geological survey firm and now primarily focuses on consulting services related to ground and groundwater, as well as soil environment consulting and purification and restoration projects to maintain a rich global environment. In our country, natural disasters caused by earthquakes, heavy rains, and typhoons, such as the Great East Japan Earthquake and the Hiroshima heavy rain disaster, are frequent. This is exacerbated by Japan's unique vulnerable ground and steep terrain, which amplify the scale of disasters. In such a natural environment, the role our company plays as a group of ground experts (Geo-Doctors) is becoming increasingly important. We aim to further refine the ground and soil environment-related technologies that form the foundation for the development of social infrastructure and the construction of a sustainable society, providing optimal solutions and contributing to society so that everyone can live safely and securely. We will continue to prioritize our customers and strive for further development of our business, so we kindly ask for your guidance and encouragement.
