The "Ultra Column Method" is a mechanical mixing deep mixing treatment method that uses a cement-based solidifying material slurry. It employs a unique cross-shaped anti-rotation wing on the excavation head, which reduces the mixing failure caused by the soil rotation phenomenon that can be problematic in viscous ground. Additionally, immediately after construction, the resistivity of the column is measured with a mixing tester to confirm the mixing condition, allowing for the construction of high-quality columns. 【Features】 ■ Improved mixing efficiency through unique technology ■ Reliable quality control ■ Various improvement forms available ■ Suitable for small-scale buildings ■ Adaptable to various sites ■ Compatible with a wide range of soil types *For more details, please download the PDF or feel free to contact us.

• Special Construction Method

The "Screw Press Method" is a ground improvement technology suitable for small-scale construction that enables the formation of thinned wood piles or crushed stone columns. Using the principle of a screw nail, it creates a compaction phenomenon by pushing the surrounding soil with the volume of the screw itself, resulting in a stronger foundation. Additionally, there is no generation of excavated soil. This significantly shortens construction time, eliminates the need for soil disposal, and greatly contributes to environmental conservation. 【Features】 ■ Improves ground bearing capacity to achieve "earthquake-resistant foundations" ■ Enables significant reduction in construction time and costs ■ Environmentally friendly low-carbon ground improvement method *For more details, please download the PDF or feel free to contact us.
