At Kyoa Development, we conduct "Indoor Soil Testing and Rock Testing" to perform laboratory tests on the physical, chemical, strength, and deformation characteristics of soil and rock samples collected on-site. 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. We also accommodate special tests that are not covered by JIS or JGS standards, providing the data that our clients require.

Company information
Koa Development was founded in 1953 (Showa 28), and thanks to your support, we have surpassed our 60th anniversary. We sincerely appreciate your long-standing support. 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 such as the Great East Japan Earthquake and the Hiroshima heavy rain disaster have frequently occurred due to earthquakes, concentrated heavy rains, and typhoons. 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 of our company as a group of ground experts (Geo-Doctors) has become increasingly important. We aim to further refine the foundational technologies related to ground and soil environments to provide optimal solutions and contribute to society, ensuring the development of social infrastructure that allows everyone to live safely and securely, as well as building a sustainable society. We will continue to prioritize our customers and strive for further development of our business, so we kindly ask for your guidance and encouragement.
