We would like to introduce the "Decos Fiber & Decos Dry Method." "Decos Fiber" is a cellulose fiber insulation material made from recycled newspaper. It has long-term insulation performance that does not deteriorate over time. Additionally, the "Decos Dry Method" is a dry blowing method that does not create insulation gaps. Non-woven fabric is applied to structural materials and blown into the wall cavity. 【Features of Decos】 ■ Long-term insulation performance that does not deteriorate over time ■ No insulation gaps due to responsible construction by JCA certified technicians ■ Fire resistant ■ 20-year warranty against internal condensation damage in wooden houses ■ Does not cause sick house syndrome *For more details, please refer to the PDF materials or feel free to contact us.

• Heat insulation and heat shielding methods

The "Geocollum Method" is a versatile ground improvement technique that can accommodate thick soft layers. It involves mixing cement milk with the soil of the original ground to a specified depth, creating columnar improved bodies underground. Due to its large diameter and expected surface friction, it is effective in preventing settlement even in base grounds with an equivalent N value of around 4. 【Features】 ■ Capable of handling thick soft layers ■ Wide adaptability ■ Effective in preventing settlement even in base grounds with an equivalent N value of around 4 ■ High-quality construction achieved with construction machinery equipped with multiple measuring devices ■ Low noise, low vibration, and short construction time *For more details, please refer to the PDF materials or feel free to contact us.

• Civil Engineering Method

The "Small Diameter Steel Pipe Pile Method" is a support pile method that uses general-purpose carbon steel pipes STK-400 to reach the bearing layer and support the building. Since the steel pipe piles penetrate through soft layers, they are hardly affected by soil conditions or water levels. The installation through rotary insertion generates minimal vibrations and noise, which are often a concern for nearby areas. Additionally, it features a wide adaptability to ground conditions and site conditions, and by selecting appropriate construction machinery, it can also accommodate narrow sites. 【Features】 - Supports buildings by reaching the bearing layer with general-purpose carbon steel pipes STK-400. - Steel pipe piles penetrate through soft layers, resulting in minimal influence from soil conditions or water levels. - Generates minimal vibrations and noise that could affect nearby areas. - Wide adaptability to ground conditions and site conditions. - Can accommodate narrow sites through the selection of construction machinery. *For more details, please refer to the PDF materials or feel free to contact us.*

Our company conducts "ground surveys" using the Swedish sounding test. We push the screw-shaped tip while rotating it with the force of a 100 kg weight, measuring the number of half rotations (Nsw) to assess the hardness of the ground. In the report, we not only provide the survey data but also propose the selection of foundation specifications for the surveyed ground and measures for weak ground. 【Features】 ■ On-site surveyors are ISO 9001 certified in-house ■ The tip screw point is measured for wear each time ■ The person responsible for analysis is ISO 9001 certified in-house ■ Proposals for highly accurate data analysis and foundation specifications ■ Ground warranty system *For more details, please refer to the PDF materials or feel free to contact us.

• Geological Survey

The "Surface Improvement Method" is a ground improvement technique that can be selected when weak layers are distributed at shallow depths. It is effective for ground that has been disturbed due to plowing in agricultural fields or ground that has been damaged near the surface due to building demolition. It demonstrates excellent effects in preventing settlement, increasing bearing capacity, and preventing liquefaction, while also being low-noise, low-vibration, and ensuring peace of mind for nearby residents with short construction periods. 【Features】 ■ Excellent effects in preventing settlement, increasing bearing capacity, and preventing liquefaction ■ Low noise ■ Low vibration ■ Short construction period *For more details, please refer to the catalog or feel free to contact us.
