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 stronger 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, instantly crushing the improved body through water pressure. 【Features】 ■ The columnar improvement section encloses the soil in the lower part of the improved layer, achieving a solid foundation. ■ 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 document or feel free to contact us.

WT method

Application to the installation of various facilities! Easy construction even on soft ground or ground with high groundwater levels.

The "WT Method" is a construction technique that improves underground areas such as parking lots using the TNF method, creating a reservoir consisting of walls on four sides and a bottom slab. By forming the contact surface between the bottom slab and the underlying ground in a grid pattern, it maintains the stability of the structure even on soft ground. Additionally, since the improved ground serves as a container, construction work such as rebar and ready-mixed concrete is almost unnecessary. It allows for a shorter construction period compared to typical retention facilities. 【Features】 ■ Easy to construct even on soft ground or ground with high groundwater levels ■ Minimal construction work required as the improved ground acts as a container ■ Shorter construction period compared to conventional retention facilities ■ Can be freely shaped, allowing for the installation of oil tanks and piping systems *For more details, please refer to the PDF materials or feel free to contact us.

WT method + TNF method

Integrating the ground behavior of gas stations on weak ground! Protecting buried facilities from earthquakes and other hazards.

We introduce a suitable construction method for the burial of tanks and piping at gas stations. By applying the "WT method," we form a container to house buried facilities such as tanks using improved ground. By combining it with the "TNF method," we integrate the ground behavior of gas stations on soft ground, protecting buried facilities from earthquakes and ground subsidence. Additionally, it eliminates the need for sheet piles and bracing, achieving a reduction in construction time and costs. 【Features】 ■ Suitable for soft ground - No uplift due to the absence of piles, preventing damage to piping - Applying the TNF method under buildings and in external structures prevents damage to underground facilities ■ Achieves low cost and reduced construction time - Eliminates the need for sheet piles and bracing, achieving a reduction in construction time and costs *For more details, please refer to the PDF document or feel free to contact us.

TNF method

Over 1,300 achievements nationwide! No need for pile driving, formwork, or foundation work.

At Yoshimitsu Corporation, we carry out ground improvement to create artificial bedrock suitable for buildings on weak ground across the country. Compared to pile foundations, we achieve approximately 30% cost reduction. Since pile work, formwork work, and ground preparation work are not required, the construction period is shortened by 50%. Please feel free to contact us when you need our services. 【Features】 ■ Approximately 30% cost reduction compared to conventional methods (pile foundation) (for a total floor area of 1000 m² and pile length of 30 m) ■ Construction period shortened by 50% compared to conventional methods, as pile work, formwork work, and ground preparation work are not required (for a total floor area of 1000 m² and pile length of 30 m) ■ No piles are used, which also reduces demolition costs when dismantling the building *For more details, please refer to the related links or feel free to contact us.

Shortening construction periods and reducing costs: TNF method

"Shallow improvement" that supports the entire ground surface of the building without using piles.

The "TNF Method" is a low-cost special foundation construction method that integrates the slab and building foundation with improved ground using solidifying materials, supporting the building across the entire improved ground surface without the use of piles. By dispersing soil stress in multiple directions, it suppresses one-directional soil extrusion. Construction is possible while protecting historical heritage and other underground features. Additionally, it significantly reduces the use of rebar, concrete, and formwork. 【Features】 ■ Suppresses differential settlement ■ No uplift steps that occur in pile-supported buildings ■ The improved ground shields against surface outflow of soil and mitigates liquefaction directly beneath the building ■ Minimal impact on underground natural environments such as groundwater ■ Protects underground buried objects ■ Reduces CO2 emissions *For more details, please refer to the PDF materials or feel free to contact us.

TNF-D Method

Contributing to the overall shortening of the construction period! Compared to typical foundation shapes, the ground pressure under improved ground conditions is reduced.

The "TNF-D Method" disperses the stress under the foundation by shaping the foundation into a trapezoidal form. It reduces stress on the lower ground and supports the foundation with a solid TNF improved ground. By minimizing the volume of the foundation, it can decrease the amount of concrete, excavation, and rebar used. Additionally, it contributes to reducing environmental impact through labor-saving construction. 【Features】 ■ Reduction in foundation structure costs ■ Shortening of foundation structure construction period ■ Resolution of labor shortages ■ Reduction of environmental impact *For more details, please refer to the PDF materials or feel free to contact us.
