Ace Sand Method
Fluidize the excavated soil on-site and pump it. This allows for mass production of backfill materials and shortens the construction period.
The "Ace Sand Method" is a construction technique that involves mixing site-generated soil, mountain sand, improved soil, and solidifying agents such as cement with water to create a fluid mixture that can be pumped. The resulting sandy soil can be widely used as backfill material, filling material, and embankment material. It allows for mass production, contributing to shortened construction periods. This method enables the large-scale production of highly fluid treated soil, making it possible to carry out backfilling and ground improvement in complex terrains in a short time. It can accommodate both low and high strength requirements. 【Features】 - Recycling of construction by-products is possible. - The plant is simple and compact, suitable for small-scale projects. - Continuous mixing allows for high construction capacity and year-round backfilling. - Effective for countermeasures against consolidation settlement and liquefaction. - By incorporating a small amount of air bubbles, bleeding is suppressed. - Primarily using sandy soil results in a lower unit water volume, improving the utilization rate of generated soil. *For more details, please refer to the materials.

The adoption of lightweight fill (FCB method) and backfilling methods using fluidized treated soil is increasing. Applications are expanding to include reduction of settlement on soft ground, load reduction on landslide-prone slopes, reduction of soil pressure on structures, backfilling in difficult areas, prevention of consolidation settlement, ground improvement, and liquefaction countermeasures.
