Our company, as a well drilling contractor, has built a rich track record of groundwater development across the country for over 100 years since its establishment. In geological surveys and construction consulting, we can conduct "groundwater surveys" using high-density electrical exploration to understand groundwater flow conditions, as well as "disaster prevention geological surveys" through boring investigations to identify the causes of landslides occurring in mountainous areas. Additionally, we also perform structural foundation surveys and small unmanned aerial vehicle (UAV) surveys. 【Geological Surveys and Construction Consulting】 ■ Groundwater Surveys ■ Disaster Prevention Geological Surveys ■ Structural Foundation Surveys ■ Civil Engineering Geological Surveys ■ Physical Exploration *For more details, please refer to the PDF materials or feel free to contact us.

• Geological Survey

Our company has been a well-established well drilling contractor for over 100 years, accumulating extensive experience in groundwater development across the country. In the field of specialized civil engineering, we are capable of undertaking landslide mitigation projects, slope protection works, and bio-plaster spraying works, among others. Landslide mitigation projects include "suppression works," which aim to stop or alleviate landslide activity by altering natural conditions such as groundwater levels, and "deterrent works," which aim to stop or partially stop landslide activity through the deterrent force of structures. 【Specialized Civil Engineering Works】 ■ Landslide Mitigation Projects ■ Slope Protection Works ■ Bio-Plaster Spraying Works (Patent No. 4430793, Eco Mark Certification: 05131021) ■ Large-Diameter Water Intake Well Construction ■ Drop Boring Works *For more details, please refer to the PDF materials or feel free to contact us.
