[Reason for Adoption] Ultra Wood Column Method

Stable supply with no price fluctuations! Can be accommodated at depths of soft ground. Construction with compact machinery.

We will introduce the reasons why the "Ultra Wood Column Method" is adopted. Methods such as column improvement and steel pipe pile methods require a supporting layer or stable layer, but this method can be applied at the depth of soft ground. Additionally, it can be implemented up to a maximum of 4.5 meters, specifically addressing soft ground, so there is no need for large, high-power machinery; compact machines like pile drivers can be used. Due to these characteristics, it is adopted in cases such as: "I was told by a ground reinforcement construction company that 'reinforcement work cannot be designed because there is no supporting layer.'" "I was told that the cost of reinforcement work with steel pipe piles is high because the supporting layer is deep." "I was told that I need to implement column improvement for 8 meters in the intermediate layer of the ground." 【Features】 ■ Can be designed for soft ground ■ Construction with small machinery ■ Low raw material costs ■ Reliable because it is a construction method with certified building technology performance *For more details, please refer to the PDF materials or feel free to contact us.

Soil Cement Column Method "Ultra Wood Column Method"

Even a small diameter provides great support! A mechanical mixing deep mixing method that combines the advantages of columnar improvement methods and piles.

The "Ultra Wood Column Method" is a mechanical mixing deep mixing treatment method that constructs columnar ground improvement bodies by excavating and mixing the ground while discharging a slurry of cement-based solidifying material. It was developed to eliminate the shortcomings of both conventional columnar improvement methods and wooden pile methods, while enhancing their advantages. This method combines the benefits of columnar improvement methods, which can provide expected frictional force, and the advantages of wooden piles, which offer stable quality due to being prefabricated. Therefore, even with a small diameter and short improvement length, it is possible to achieve significant bearing capacity. Additionally, this has been proven by numerous experimental results. 【Features】 - Constructs reliable ground for small-scale buildings - Achieves large bearing capacity even with a smaller diameter than conventional columnar improvement bodies - Ensures quality control and construction management - Can be adapted to narrow sites - High mixing efficiency allows for construction in a short period For more details, please contact us or download the catalog.

Ultra Column Method NEO [A Ground Improvement Method Realizing Low Residual Soil]

Achieving low residual soil! A ground improvement method that concentrates the cement milk to a high density with a water-to-solid ratio of up to 40%.

The "Ultra Column Method NEO" is a mechanical mixing deep mixing treatment method that uses a cement-based solidifying material slurry. By using a special additive (Ultra Liquid), the water-to-solid ratio of the cement milk can be concentrated up to 40%, allowing for the construction of high-strength, low residual soil columnar improvement bodies. 【Features】 ◆ Quality inspection that usually takes about a week can be completed on the same day ◆ Reduction in the amount of solidifying material ◆ Decrease in generated residual soil ◆ Low noise and low vibration 【For more details, please download the catalog or feel free to contact us】
