A ground continuous wall method that can accommodate narrow sites and allows for construction at a maximum depth of 20 meters with small machinery. It can also be adapted for permanent retaining walls through the installation of concrete sheet piles!
The "Mini Wall Method" is a construction technique that creates a soil-cement underground continuous wall with high water-stopping ability and uniform vertical strength by mixing and agitating cement slurry discharged from the base ground and the bottom end of the posts using a chainsaw-type cutter mounted on a cutter post in a vertical direction. Since uniform thickness walls can be created, it is possible to install core materials at arbitrary intervals, allowing for high design flexibility and economical soil retention and water-stopping continuous walls. 【Features of the Mini Wall Method】 - Due to the uniform thickness of the wall, the installation interval of the stress core materials can be set arbitrarily. - Wall thickness can be adjusted by changing the cutter bits. - Construction is possible close to structures and at property boundaries. - The use of a suspended leader allows for step construction (5-6 meters). *Please refer to the PDF data for the catalog and construction examples of the "Mini Wall Method" available for download.

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.
