Next-generation liquefaction prevention method [KB Drain Method]

We have established a technology to install special drainage pipes that can be expected to lower groundwater levels underground without excavation.

The KB Drain Method is a non-excavation groundwater lowering technique that establishes the technology to lay special collection and drainage pipes without excavating the target ground. Traditionally, the mainstream method was to drive piles for liquefaction countermeasures, but this method increases resistance to liquefaction by lowering the groundwater level and increasing the thickness of the non-liquefied layer. As a result, construction in urban and residential areas, which was difficult with conventional excavation methods, becomes possible. 【Features】 ■ Safe and reliable construction method ■ Construction in narrow spaces ■ Compatible with a wide range of soil types ■ Long-distance construction with a 100m span ■ Economical with compact equipment ■ Fast with fewer processes *For more details, please refer to the PDF materials or feel free to contact us.
