The 7th International Symposium on Soils for Transportation Construction in Cold Regions, TRANSOILCOLD 2025, took place in Incheon, South Korea. The event served as a leading international platform for sharing knowledge and practical experience in designing, constructing, and operating transportation infrastructure in the Arctic and other cold regions. The symposium also covered topics related to geotechnical design, including geophysics, slope stability, soil dynamics, numerical modeling, geosynthetics, and other important areas.

During the event, scientists from the International Educational Corporation (KazGASA) presented the results of their research on the topic: “Application of Deep Soil Mixing Technology for Strengthening the Soil Foundations of Cities in Southern Kazakhstan.” In their presentation, the researchers discussed the application of the Deep Soil Mixing (DSM) method in the cities of Almaty and Shymkent.

The scientists from IEC (KazGASA) noted that the Deep Soil Mixing method is more effective and cost-efficient compared to traditional methods used in Kazakhstan. The presentation included the results of field tests of soil-cement columns performed using the vertical static load method, as well as laboratory research data determining the physical-mechanical properties of the reinforced soil.

The findings from the research have already been applied in the design of construction projects in Almaty and Shymkent and may serve as the basis for further studies in the region’s seismic activity conditions.
