TNF+ Method

A new construction method applicable to mid-rise and high-rise buildings! Utilization of geothermal energy such as heat pumps is possible.

The "TNF+ (Plus) Method" enhances the "TNF Method (a shallow improvement method with a grid-like structure)" by applying columnar improvements to the bottom layer, making the ground even more solid and protecting buildings from weak ground. The improved layer can be formed into various shapes, allowing for the free installation of underground structures. At the time of land return, a pipe water jet is injected into the installed pipes, instantly crushing the improved body using water pressure. 【Features】 ■ The columnar improvement section encloses the soil in the lower part of the improved layer, achieving a solid ground. ■ A new method applicable to mid-rise and high-rise buildings. ■ The improved layer can be formed into various shapes, allowing for the free installation of underground structures. ■ By installing pipes in the columnar section, geothermal utilization such as heat pumps is possible. ■ High-pressure water is injected from the pipes installed in the columnar section to crush the improved body. ■ The improved body can be dismantled in a short period, reducing the cost of restoring the land to its original state. *For more details, please refer to the PDF materials or feel free to contact us.
