We provide all the ground information you need! We investigate the soil layer composition and more using a boring machine.
"Boring investigation" is the most fundamental method of geological survey. By using a boring machine to excavate and observe the collected samples, the composition of the strata can be understood. Generally, a standard penetration test is conducted during excavation to measure the N value (an indicator of the relative density and hardness of the ground). Our company plans and proposes various tests and surveys using the borehole, as well as sampling when necessary during boring, providing all the ground information required by our clients.

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.
