The investigation to be conducted as the next step of the overview survey! Mainly, we will carry out an investigation into the depth of contamination.
At Kyoa Development, we conduct a "Detailed Survey" as the next step following the overview investigation. The "Detailed Survey" is a depth investigation of contamination conducted when soil pollution is confirmed (when specific harmful substances exceed the standard values). Since the methods of investigation vary depending on the depth of the contamination source and the soil and geological conditions, these tasks require a wide range of specialized knowledge and know-how. Our company continuously provides education and training for the technicians engaged in these tasks, enabling us to deliver speedy and highly accurate investigation results. 【Features】 ■ Environmental investigation drilling machine (Eco Machine) - Generates minimal excavation waste, resulting in less contaminated soil storage and processing - Fast excavation speed and easy machine mobility - Capable of drilling up to 20-30 meters ■ Providing speedy and highly accurate investigation results *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.
