Numerous achievements such as early recovery in disaster areas and reduction of total costs through shortened construction periods! A construction method using lightweight, fluid, bubble-mixed lightweight soil.
The "FCB Method" is a construction technique that uses bubble-mixed lightweight soil as fill material, leveraging the characteristics of bubble-mixed lightweight soil (air mortar, air milk) such as lightweight, fluidity, and self-supporting properties. It is a lightweight embankment method that enables load reduction on soft ground, alleviation of soil pressure behind bridge abutments, and filling in locations where conventional soil construction is difficult. Due to its lightweight nature, when used for embankments or backfilling, it can reduce the load and soil pressure on the ground and structures. Additionally, its good fluidity and the fact that no compaction is required make it suitable for backfilling in narrow spaces and for filling various voids. 【Features】 - Easy to retain due to its lightweight - Fluidity allows for easy construction - Freedom in setting strength and weight - Excellent durability - Easy to remove - Utilizes construction by-products *For more details, please refer to the catalog or feel free to contact us.

Company information
In the mid-1950s, during a period of construction boom leading up to the Tokyo Olympics, Asou Sangyo Co., Ltd. (now Asou Corporation) focused on the increasing demand for lightweight and labor-saving high-rise buildings. They recognized the advantages of using aerated concrete (air mortar), which excels in lightweight properties and thermal insulation, as insulation material, and established the company with the aim of manufacturing and constructing building-grade aerated concrete. The unique technology developed through research and development of imported technology from the United States, along with the excellent characteristics of their product (aerated concrete), matched the needs of the times. It was used for waterproofing on rooftops to reduce the weight of high-rise buildings, raising floor slabs on each floor, and embedding piping in mechanical rooms. Subsequently, the lightweight properties of aerated concrete attracted attention from various fields, leading to its adoption in numerous civil engineering projects, including the Tōkaidō Shinkansen construction. To date, the construction achievements have exceeded 10 million cubic meters, and the company continues to provide satisfaction to the times and society as a pioneer of air mortar and a technology development-oriented enterprise that responds to various needs.
