Protecting Japanese buildings from earthquake disasters! Because it's in unseen areas, assurance of seismic and environmental performance is essential.
The "Screw Press Method" is a ground improvement technique that enhances soil bearing capacity, creates earthquake-resistant ground, and is an environmentally friendly low-carbon ground improvement method. The crushed stone columns created by this method compact the entire ground through pressure, and even if shear occurs, it has little effect on strength, while also effectively attenuating seismic waves, protecting your valuable home from earthquakes. It demonstrates tremendous effectiveness in liquefaction countermeasures by strongly compacting the ground and dissipating pore water pressure through highly permeable piles. This method resolves the concerns and worries associated with traditional ground improvement work, creating a reliable foundation to support buildings. 【Features】 ■ Significant reduction in construction time and costs ■ Environmentally friendly low-carbon ground improvement method ■ Capable of forming piles from thinned wood or crushed stone columns ■ Excavation method with zero excavation residual soil ■ Crushed stone columns are strong against earthquakes and significantly reduce liquefaction phenomena *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Suitable Sites】 ＜Thinned Timber Piles＞ ■ Sites where piles can be driven into a supporting ground with an N value of approximately 10 or higher, and a surface soft layer generally less than 5m deep. ■ Sites that have been developed through cutting and filling, where piles can be driven down to the supporting ground. ＜Crushed Stone Columns＞ ■ Sites with a thick surface soft layer and a deep supporting layer. ■ Sites that have been filled on top of a soft layer. ■ Sites prone to liquefaction. *For more details, please refer to the PDF document or feel free to contact us.
