It is a full casing (full rotary) method that enables work up to a depth of 4.4 meters.
We have made it possible to carry out construction that was previously impossible. - Foundation work inside the gymnasium: Previously, part of the wall had to be demolished to bring in machinery, but it is now possible to bring in equipment without altering the current state. - Foundation work along the railway: Work that requires crane booms to extend higher than the tracks is typically done at night, but since we do not use cranes, daytime work is possible. - Bridge widening and under-beam work: Heavy machinery can access the existing under-beam area, allowing vehicles to continue using the existing bridge during construction. - Work under high-voltage power lines: Construction under high-voltage power lines is also feasible.

Company information
Our company was founded in 1958 and specializes in underground special civil engineering works such as underground continuous walls, underground obstacle removal, ground improvement, and pipeline construction. In recent years, we have expanded our business operations to include slope work and construction. There is a growing social demand for securing the natural environment, seismic reinforcement, liquefaction prevention, restoration of structures, and urban redevelopment, which have become pressing issues in recent years. In response to these social needs, we have developed seismic reinforcement and liquefaction countermeasure methods such as the "Ultra Multi-Point DP Method" and the "High Grip Grout Method." For structural restoration, we utilize our in-house developed restoration method called "Suiheikun," and for urban redevelopment, we are conducting research and development of new methods such as the "Hiro Work Kmigty Method," "Bauer Method," and "Super Top Method," aimed at underground obstacle removal. Additionally, as part of our eco-friendly initiatives, we are researching and developing methods that use bubble drilling fluid to reduce industrial waste, striving to contribute to society through high-quality construction and services. We aim to continue responding to the needs of the times by deploying a variety of specialized techniques and uniquely developed methods.
