Select a better ground reinforcement method from the ground survey! A method that ensures safety and cost-effectiveness.
The "Tōshō-style Column Method" is a construction technique that involves mixing and blending cement-based solidifying material slurry with the ground to create a column-like ground improvement body. It can be used for a wide range of applications, including the foundation construction of buildings and structures, settlement of embankments, sliding prevention measures, earth retention walls, and water stop walls. It is less affected by soil conditions, allowing for flexible responses. 【Features】 - Applicable to sandy soil, silt, clay, and organic soil, and is less constrained by soil types. - The soil quality of the improved area and the mixing of the improvement body can be visually confirmed, allowing for flexible responses to various soil conditions and enabling uniform mixing. - Achieves low noise and low vibration during construction. - Generates minimal dust due to slurry mixing. - Mixing is achieved through the up-and-down, forward, and reverse rotation of the mixing blades, preventing soil circulation and enabling uniform mixing. *For more details, please download the PDF or feel free to contact us.

Our company was established in 1993 as a ground improvement construction company. Since our founding, we have worked to develop and promote the Tohsho-style column method, enabling deep mixing treatment (column improvement) even in ground with the unique corrosive soil of Hokkaido, and we have accumulated a significant number of construction achievements to date. In 2008, we introduced the Ultra Column method, and in 2010, the Ultra Wood Column method. Furthermore, in 2012, we obtained the construction technology performance certification for the S-Max Column method, and in July 2013, we began construction of the block-shaped mixing treatment method known as the Rising method. Our achievements have further expanded, including general housing, reinforced concrete structures, steel structures, and public housing and school construction projects.
