At Kyoa Development, we conduct "Indoor Soil Testing and Rock Testing," where we perform laboratory tests on soil and rock samples collected on-site to evaluate the physical, chemical, strength, and deformation characteristics of the ground. The "Indoor Soil Testing" is carried out using sampling materials (undisturbed samples and disturbed samples) to understand the physical and mechanical properties of the ground. Additionally, we accommodate special tests that are not covered by JIS or JGS standards, providing the data that our clients require. Our testing centers are located in two places: Kanto (Chiba City, Chiba Prefecture) and Kansai (Sakai City, Osaka Prefecture), and we also welcome clients to attend the tests. 【Features】 ■ Indoor testing ■ Support for special tests beyond JIS and JGS standards ■ Provision of data required by clients ■ Attendance at tests is also supported *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.
