Ground improvement work "Tenokoram Method"

The Tenokoram method can solidify weak ground and improve it into high-quality ground!

The "Tenokoramu Method" is a technique that solidifies the ground into column shapes using solidifying materials. We confirm the "improvement system" for all soil types, including loam and organic soil, and by introducing a construction system that allows real-time management of our self-developed construction conditions, we have successfully enhanced the reliability of underground construction that is not visible to the public, gaining strong trust from our users. This method is mainly used for foundation ground improvement of buildings, with a vast track record ranging from single-family homes and apartment buildings to large shopping centers and skyscrapers. 【Features】 ■ It is possible to create high-quality, high-strength columns that are not found in conventional ground improvement methods through mixing and construction management. ■ Mechanization significantly reduces dangerous work, allowing for safer operations. ■ Improvement effects can be obtained early. ■ The construction process is simple, allowing for significant reductions in construction time and enabling economical design. ■ It is not limited by soil type; it can be applied to sandy soils as well as highly cohesive clay and loam. ■ It is also compatible with peat. *For more details, please download the PDF or feel free to contact us.

[Construction Example] Laundry Factory: Filling Work for Loose Ground Under Machinery Foundation

Injecting polyurethane under the foundation to eliminate ground looseness! Solved in just one day!

We would like to introduce a case of "filling work for loosening under the machine foundation and urethane filling work inside the pit" conducted at a laundry factory in Kanagawa Prefecture. Due to the loosening of the ground under the machine foundation, the dewatering machine tilted, so we performed filling work to inject urethane under the machine foundation to resolve the ground loosening. Additionally, we carried out work to fill urethane inside the pit where the dewatering machine is installed to prevent further subsidence. After the construction, we conducted a filling confirmation using a CCD camera and confirmed that the urethane was evenly filled under the machine foundation. [Case Overview] ■ Construction Area: 10m² ■ Construction Period: 1 day ■ Area: Kanagawa Prefecture *For more details, please refer to the PDF document or feel free to contact us.

Ground Improvement Work "Rising Method"

Before construction, underground obstacles can be removed, and after construction, the mixing condition can be checked with a rising tester (resistivity meter)! It is environmentally friendly with low noise and low vibration.

The "Rising Method" is a ground improvement technique that involves placing pre-excavated soil into the excavation area and mixing it with slurry using a uniquely developed mixing bucket to create a homogeneous block-like improved body. By excavating the soil in advance, it allows for the confirmation of the "support layer and the soil to be improved," and also enables the removal of "organic soil that hinders solidification, as well as gravel layers, boulders, industrial waste, and underground obstacles that may interfere with construction," thus achieving several benefits. *After construction, the mixing condition can be checked with a Rising Tester (resistivity measuring device). It has obtained the Architectural Technical Performance Certification from the Japan Building Disaster Prevention Association. 【Features】 ■ Reliable quality control ■ Enhanced mixing effect with unique technology ■ Applicable to both small buildings and civil engineering structures ■ Compatible with a wide range of soil types ■ Confirmation of advanced ground conditions ■ Low noise and low vibration *There is also the "Ultra Column Method," which can reduce mixing failures caused by the soil's co-rotation phenomenon, which is problematic in low-viscosity ground. *For more details, please refer to the PDF materials or feel free to contact us.
