Surveys can be conducted in narrow sea areas and shallow waters! We also introduce multi-channel shallow reflection methods that allow for deep investigations!
At Kōa Development, we conduct "acoustic wave exploration," which allows for detailed investigations and deep surveys by changing the sound source and frequency. By emitting sound waves towards the seabed and observing reflections at acoustic impedance boundaries, we can understand the geological structure beneath the sea surface. We carry out everything from measurement to analysis in-house, providing rapid and highly accurate exploration results. 【Features】 ■ Detailed investigations and deep surveys are possible by changing the sound source and frequency. ■ A wide range of surveys offered: - Investigation of burial conditions in ports and shipping routes using parametric acoustic wave exploration. - Surveys of active fault lines in coastal areas and other shallow marine investigations. - Geological structure surveys at depths of several hundred meters using boomer and sparker technologies. *For more details, please refer to the PDF materials or feel free to contact us.

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.
