HEESONG GEOTEK CO., LTD.

HEESONG GEOTEK CO., LTD. specializes in geotechnical drilling and site-specific seismic investigations for defense infrastructure, delivering critical subsurface data to support military facility planning and risk mitigation. Their core expertise lies in executing precision borehole drilling, soil and rock sampling, and in-situ geophysical testing at sensitive U.S. military installations, particularly in Korea. The contractor provides engineered geotechnical solutions tailored to complex terrain and seismic hazards, ensuring compliance with DoD standards for foundation design, slope stability, and earthquake resilience. Their technical proficiency includes advanced borehole logging, standard penetration testing, and seismic refraction surveys, enabling data-driven decisions for base expansion, runway reinforcement, and critical infrastructure protection. The company maintains a consistent, long-term relationship with the Department of Defense, primarily supporting U.S. Army and Air Force installations in the Republic of Korea. Their work focuses on mission-critical geotechnical investigations at forward-operating bases, including Osan AB, Kunsan AB, and Humphreys, where environmental and seismic conditions demand high-accuracy subsurface characterization. This recurring engagement reflects a trusted role in sustaining operational readiness through geospatial and geomechanical intelligence. The contractor’s primary industry focus is Support Activities for Nonmetallic Minerals (Except Fuels), which in practice translates to subsurface exploration and geotechnical field services essential for civil and military construction. They operate at the intersection of geology, engineering, and defense infrastructure, serving a niche market requiring rigorous field data collection under austere conditions. HEESONG GEOTEK CO., LTD. is a South Korea-based entity structured as a 2L firm with no federal certifications on record. While not formally registered in U.S. government certification programs, its consistent performance on DoD contracts demonstrates deep familiarity with military technical requirements and operational environments in the Indo-Pacific region.
