The "Litera Method" is a construction technique that uses a self-propelled soil improvement machine called "Litera" to mix soil and solidifying agents on construction sites. It can be implemented in narrow yards and has high improvement efficiency, significantly reducing the drop of untreated areas. Due to the low dust generation, it can also be carried out in residential areas and alongside roads. Examples of this method's application include "safety measures for skin drop at tunnel portal heads" and "dust control" among other construction cases. 【Features】 ■ Prevention of environmental destruction and resolution of secondary pollution ■ Significant cost reduction made possible by on-site processing ■ High-quality assurance due to the use of high-performance soil improvement machinery ■ Feasible in narrow yards ■ High improvement efficiency significantly reduces the drop of untreated areas ■ Low dust generation allows for implementation in residential areas and alongside roads *For more details, please refer to the PDF materials or feel free to contact us.

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.

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.

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.

We would like to introduce our "TNF Hybrid Method." After ground improvement using the "TNF Method," we drive log piles from the improved layer. This compacts the loose sandy ground that causes liquefaction, improves the ground, and provides stable support for buildings. Additionally, the use of log piles (wood) contributes to carbon storage, helping to reduce CO2 emissions. 【Features】 ■ Low-cost liquefaction countermeasures ■ CO2 emission reduction ■ Compacts loose sandy ground and improves the foundation ■ Provides stable support for buildings *For more details, please refer to the PDF document or feel free to contact us.

The "T-BAGS Seismic Isolation Method" involves laying two layers of T-BAGS, sandwiched with a special sheet, beneath the floor slab and under the foundation. During an earthquake, the sliding of the T-BAGS absorbs the building's vibrations. Due to its extremely high durability, regular maintenance is not required. Additionally, by combining it with the TNF method, it can be applied in soft ground conditions and reduce installation costs. 【Features】 ■ Two layers of T-BAGS sandwiched with a special sheet laid beneath the floor slab and under the foundation ■ Applicable to soft ground ■ Low cost ■ Maintenance-free ■ Vibration reduction: from 300gal–800gal to below 200gal–250gal *For more details, please refer to the PDF materials or feel free to contact us.

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.

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.

This method suppresses the uplift of manholes through two functions: ground improvement by vibration and the drainage function for excess pore water pressure relief. It allows for drilling from inside the manhole to the bottom of the manhole without drawing in groundwater or soil, enabling the installation of a filter. By vibrating the manhole body and compacting the surrounding ground, ground improvement is achieved, and even if excess pore water pressure occurs due to aftershocks, it is maintenance-free, providing peace of mind. [Features] - No excavation - Maintenance-free - Resistant to aftershocks *For more details, please refer to the PDF document or feel free to contact us.

A "stockyard" is a facility that uses the liter method to recycle improved soil from construction waste generated on-site for reuse as backfill material or backfill material. Since construction waste is recycled on-site, it significantly reduces disposal costs and new purchase costs. It can accommodate various types of soil, supply improved soil at a plant-level workload, eliminate mixing inconsistencies, and reduce the amount of solidifying agents. **Benefits of Recycling Construction Waste:** - Prevention of environmental destruction and resolution of secondary pollution - Significant cost reduction made possible by on-site processing - High-performance soil improvement machinery ensures quality *For more details, please refer to the PDF document or feel free to contact us.*
