"Shiga Prefecture Ground Improvement" Ground Reinforcement Method 'Woody Force Method'

Applicable to sandy and clayey soil in Shiga Prefecture! This is an ecological and environmentally friendly method that utilizes small-diameter thinned wood as ground reinforcement material for housing!

The Woody Force method is a ground reinforcement technique aimed at small-scale buildings, utilizing unused thinned timber. This method uses thin-diameter thinned timber of "sugi" (Japanese cedar) or "hinoki" (Japanese cypress), which is somewhat too slender for use as house pillars and has been largely underutilized, as ground reinforcement material for houses, making it eco-friendly. By applying anti-corrosion and anti-termite treatment that complies with AQ certification (certification for quality wood building materials, etc.) B-3 (outdoor product components) to the wood used as ground reinforcement material, we aim to further enhance durability. 【Features】 ■ CO2 Reduction - Does not use cement or steel, which emit large amounts of CO2 during the manufacturing process - Contributes to energy conservation and reduction of greenhouse gases ■ Durability - By applying anti-corrosion and anti-termite treatment that complies with AQ certification B-3 to the wood used as ground reinforcement material, we aim to further enhance durability. *For more details, please refer to the PDF document or feel free to contact us.

Optimization of Foundation Costs for Weak Soil in Condominium Development | Geotech

Reduce ground risk and optimize the foundation costs of condominium developments.

In condominium development, the long-term safety of the building and cost management during the planning stage are crucial. Particularly in the case of weak ground, there are concerns about increased costs due to ground improvement and pile construction, which could impact the overall financial balance of the project. Inadequate ground measures may increase the risk of future differential settlement, potentially affecting residents and leading to repair costs. Our advanced analysis methods utilize stress distribution analysis of building loads and precise settlement simulations to optimize foundation costs in weak ground. This helps to suppress unnecessary deep improvements or pile work based on excessive safety factors, enabling the adoption of direct foundations. By employing evaluation criteria that cover legal standards, we ensure high structural safety while preventing excessive reinforcement, and reliable technical evidence can be used for application submissions and explanations to clients. 【Application Scenarios】 - Condominium construction projects on weak ground - Assessment of ground risks and consideration of mitigation measures - Optimization of foundation construction costs - Ensuring structural safety and preparing explanatory materials 【Effects of Implementation】 - Reduction of excessive ground improvement costs - Improved cost efficiency for the entire project - Enhanced long-term safety of the building - Planning based on reliable ground data

Ground reinforcement work using the ETP method for factories.

Ground reinforcement supporting stable operation of factory production lines.

In a factory, the stable operation of the production line is the foundation for business continuity. Particularly in environments where heavy machinery is installed or vibrations occur, ground subsidence and differential settlement can lead to serious issues such as decreased production efficiency, equipment damage, and even the stoppage of the production line. To mitigate these risks and achieve long-term stable operation, reliable ground reinforcement suitable for the building's scale and geological conditions is essential. The ETP method, with its wide range of applications and flexible design capabilities, addresses various ground challenges specific to factories and supports the stable operation of production lines. 【Usage Scenarios】 - Ground reinforcement in heavy machinery installation areas - Ground stabilization around vibration sources - Ground improvement accompanying production line expansion - Ground subsidence countermeasures for existing factories 【Benefits of Implementation】 - Increased productivity due to stable operation of the production line - Reduced risk of equipment damage - Avoidance of unexpected production stoppages - Protection of long-term capital investments

Reduction of fixed materials, decrease in generated residual soil, and improved mixing efficiency! 'Rising Method'

By using a special mixing agent, the water-to-solid material ratio of cement milk can be concentrated up to 40%, enabling the construction of high-strength improved soil!

The "Rising Method" is a ground improvement technique that involves placing pre-excavated soil into the excavation area and using a uniquely developed mixing bucket to mix the soil with slurry (W method) or soil with solidifying agents (D method), thereby constructing a highly homogeneous block-like improved body. By excavating the soil in advance, it allows for the "confirmation of the supporting 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 impede construction," achieving various benefits. Additionally, in the W method, as a quality control test immediately after construction, the resistivity of the improved body is measured to confirm the mixing conditions. 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 small buildings as well as civil engineering structures ■ Compatible with a wide range of soil types ■ Confirmation of advanced ground ■ Low noise and low vibration *For more details, please refer to the PDF materials 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.

Georegistration Method for Construction Sites

Early understanding of the effects of improved ground and enhancement of quality control.

In the construction industry, accurate understanding of the improvement range and strength is required for quality control in ground improvement work. Particularly in chemical grouting and cement-based ground improvement methods, variability in improvement effects and uncertainty in the improvement range can pose challenges. The GeoRegister method addresses these issues by simultaneously conducting dynamic cone penetration tests and electrical resistivity surveys immediately after construction, allowing for early estimation of improvement strength and range. 【Application Scenarios】 - Quality evaluation of improved ground where chemical grouting is difficult - Cement-based ground improvement methods such as deep mixing treatment and soft ground treatment - Investigation of narrow areas where boring core sampling is impossible and facilities in use 【Benefits of Implementation】 - Early quality and shape management - Visualization of improvement range and strength - Potential for shortening construction time and reducing costs
