"Three S G Method" A deep mixing treatment method that pursues economic efficiency and high quality.
Over 8,700 construction achievements across all 47 prefectures in Japan! Thanks to our original construction quality management method, quality verification can be done as early as one day after construction!
In the construction method of the mechanical stirring type deep mixing treatment using conventional cement-based solidifying material slurry, a new technology has been introduced by installing the cement milk discharge ports above and below the stirring blades. During excavation, slurry is injected from the lower discharge port, and during extraction, it is injected from the upper discharge port, maximizing stirring efficiency and enabling the creation of high-quality improved bodies with minimal strength variation. (The stirring device has been patented.) Furthermore, as a result of pursuing quality improvement and efficiency enhancement, significant improvements have been realized through this new technology. In 2007, it obtained a construction technology performance certification from the Japan Building Disaster Prevention Association as the "Three S G Method." In 2009, the first revision was made, and the "Three S G-cube Method" (G-Cube Method) was developed for small-scale buildings. In 2011, a second revision was made based on accumulated construction results, achieving an expansion of the application range and a significant improvement in cost performance. Efforts are also being made to enhance practical training within the method association. Various training programs for obtaining certification have been recognized as eligible for subsidies from the Human Resource Development Support Grant (Ministry of Health, Labour and Welfare) and the Small and Medium Enterprises Capability Development Grant (JMAF Foundation), establishing an educational system for method engineers.
