Business sectors

• Foundation work: Includes ground preparation and foundation work such as BG-cast-in-place pile method and Diaphragm Wall, and utilizes a method of excavating by rotating a tool suitable for the soil type or pile diameter.
• Tunnel Projects: We specialize in tunnel construction utilizing mechanized tunneling methods such as Shield TBM, Open TBM, and SEMI Shield, and enhance safety by installing support structures immediately upon excavation.
• Engineering: We provide comprehensive engineering services, including geotechnical investigation, soil and foundation design, mechanized tunnel design, specialized analysis, and design modification, to select optimal construction methods and execute rational designs.

Products

• BG-Cast-in-Place Pile Method: This is a method of excavation in which a tool suitable for the soil type or pile diameter is rotated. It is easy to determine the soil type during excavation, resulting in high concrete quality and relatively easy construction management.
• Shield TBM Method: This is a tunnel construction method actively utilized worldwide because it minimizes the risk of collapse by installing support segments immediately upon excavation, and generates virtually no construction pollution (traffic obstruction, noise, vibration, dust, etc.) during construction.
• Diaphragm Wall: This is a construction method widely used in large-scale urban projects, involving the construction of plain or reinforced concrete walls underground after excavating a trench, while supplying a stabilizing fluid to prevent the collapse of the excavation surface and groundwater infiltration.

Special Features

• Development of New Technologies and Construction Methods: Through continuous research and effort, we are striving to acquire advanced construction capabilities by developing new technologies and methods applicable to various sites.
• State-of-the-art Equipment and Expertise: We possess a wide range of world-class, cutting-edge equipment necessary for underground space development, backed by extensive construction experience, an excellent technical team, and advanced technical capabilities concentrated with expertise.
