Three-layer structure Soil Cement Column Method "ef Column"

Achieving high support strength and high quality! A construction method that excels in both environmental and cost aspects.

The ef column method is an evolved soil cement column technique that achieves high load-bearing capacity and high quality, while also being excellent in terms of environmental and cost aspects for a new era. In the ef column method, a core steel pipe is adopted at the center of the soil cement column, and a layer of high compressive strength solidifying agent milk is placed around its outer circumference. This three-layer structure not only realizes excellent load-bearing capacity but also prevents corrosion of the core material. Additionally, during dismantling and removal, the core material serves as a guide for the excavation blade, making it possible to remove the improved body more reliably and easily than conventional methods, which is its greatest feature. 【Features】 - Significant improvement in load-bearing capacity due to the adoption of the core steel pipe - Small improvement diameter with high strength - Reduction in cement usage, lowering material costs and environmental impact - Easy removal of soil cement columns *For more details, please contact us or download the catalog.
