An environmentally friendly ground improvement method that uses 100% natural material crushed stone. It prevents the collapse of the borehole walls with casing, allowing for stable quality construction.
The "Eco-GEO Method" is an environmentally friendly ground improvement technology developed through joint research between Mie University and Onabe Group, which uses only "crushed stone" without the need for cement or steel pipe piles. It can be utilized for ground improvement work for residential buildings and small civil engineering structures. Furthermore, in September 2013, "Eco-GEO ZERO," which can be constructed without soil disposal, was born, making it possible to carry out construction in urban areas without disposal sites. It does not require cement plants, generators, or compressors that were necessary for conventional ground improvement work, and it allows for construction using a compact ground improvement machine (8-ton class) equipped with a uniquely developed EG casing (a steel tube with a rubber door) and a backhoe. The EG casing is driven into the ground, and crushed stone is filled and compacted into the space created during the extraction process. Since a compact ground improvement machine (approximately 2.0m wide) is used, it can be constructed even in narrow spaces.

It is possible to create a stable quality crushed stone pit without collapsing the excavated hole, even in weak ground with groundwater!
We would like to introduce our residential crushed stone ground improvement work, the "Eco Geo Method." When the holes excavated during construction collapse and soil mixes with the crushed stone, the strength of the crushed stone column decreases. Our method successfully prevents this by using our uniquely developed EG casing. Even in weak ground with groundwater, we can create a stable quality crushed stone column without collapsing the excavated holes. 【Features】 ■ Ensures the prevention of wall collapse in the holes ■ Creates a reinforcement body made solely of crushed stone without soil mixing ■ Ensures the designed bearing capacity and permeability *For more details, please download the PDF or feel free to contact us.
Ground improvement work varies in CO2 emissions and the materials left underground depending on the materials and methods used!
As efforts towards the SDGs are being demanded worldwide, measures against global warming and waste reduction are urgent issues. In ground improvement work, consideration for the global environment is also required. Ground improvement work varies in CO2 emissions and the materials left underground depending on the materials and methods used. Additionally, attention must be paid to soil contamination. *For more detailed information, please refer to the related links. Feel free to contact us for more details.
As a result of examining the three aspects (cost, market, and profitability), it has been determined that the possibility of factors causing a decline in land prices is low!
The Eco-GEO method is a ground improvement technology developed based on joint research between Onabe Group Co., Ltd. and Mie University, using only crushed stone. It is a ground improvement technology that has a low impact on the global environment and a low possibility of decreasing land value. In this technology, crushed stone remains underground, but based on the evaluation from the joint research paper by Onabe Group and Mie University, it was assessed by real estate appraisers that "the possibility of decreasing land value is low." 【Features of the Eco-GEO Method】 ■ Ground improvement technology using only crushed stone ■ Low impact on the global environment ■ Low possibility of decreasing land value *For more details, please download the PDF or feel free to contact us.
We will introduce examples of cases where it has been adopted due to the use of casing, ensuring stable quality.
We would like to introduce a case where the Eco-GEO method was adopted for ground improvement in caisson construction. In caisson ground improvement work, ground improvement using gravel piles is the standard specification. Due to the small size of the machinery (width 2.0m, weight approximately 11t), parallel work with other construction projects is possible, leading to a reduction in construction time, which is why this method was adopted. Please feel free to contact us when you need our services. 【Project Overview】 ■ Construction Location: Saitama Prefecture ■ Design and Construction Depth: 4.76m ■ Number of Design and Construction: 292 piles *For more details, please download the PDF or feel free to contact us.
Introducing examples that can be widely applied in residential and public works!
We would like to introduce a case where our residential crushed stone ground improvement work, the "Eco Geo Method," was adopted as a liquefaction countermeasure in public works in areas affected by liquefaction during the Great East Japan Earthquake. In conventional technology, the construction of crushed stone piles required for liquefaction countermeasures was difficult without large machinery. Our technology allows for the construction of "homogeneous crushed stone piles" required for liquefaction countermeasures through "casing." In the future, it can be applied not only to the recovery and reconstruction of disaster-stricken areas but also to liquefaction countermeasure works for residential and public projects nationwide. [Case Overview] ■ Project: Liquefaction countermeasure work for public housing ■ Project Details: Crushed stone pile installation depth of approximately 4.0m, quantity of about 750 piles ■ Client: Abiko City, Chiba Prefecture ■ Construction Period: December 2013 to January 2014 (approximately 1 month) *For more details, please download the PDF or feel free to contact us.
![High Cement Content Soil Improvement Agent MT Series [Construction Video] Self-Propelled Soil Improvement Machine](https://image.www.ipros.com/public/product/image/fbc/2001144038/IPROS11066509544216555492.png?w=280&h=280)
[Video] By improving with the MT-2, it is now possible to enhance high moisture content clay soil using a self-propelled soil improvement machine!
We would like to introduce a construction video of the high cement content soil improvement agent MT series. It is a short video of about 1 minute and 30 seconds, so please take a look. This work involves creating improved soil using a self-propelled soil improvement machine. Until now, a challenge has been that high moisture content mud could not be fed into the self-propelled soil improvement machine. Therefore, as a primary treatment, we improved it with MT-2, resulting in a property that can be fed into the self-propelled soil improvement machine. Subsequently, the MT-2 improved soil was further treated with quicklime as a secondary treatment using the self-propelled soil improvement machine. It has also been confirmed that adding MT-2 does not affect the strength development of the improved soil. *For more details, please watch the video or feel free to contact us.

The DHJ-12 is a ground improvement machine equipped with a high-power engine, extending the auger stroke by 1 meter and enhancing its excavation power. It combines excellent operability with a compact body, improving construction efficiency. Additionally, it is capable of excavating a diameter of 1,000 mm and a depth of 11 m, further increasing its excavation power (the excavation diameter and depth may vary depending on the method and ground conditions). The auger torque has also increased to 27.4 kN·m (2.8 tf·m), enhancing construction efficiency. [Features] ■ The rotation torque and speed can be set arbitrarily. ■ The expanded range of speed adjustment allows for construction with appropriate settings suited to the ground conditions. *For more details, please download the PDF or feel free to contact us.
Ground improvement work may decrease the value of the land! Regarding the impact on land value.
If there are items buried underground from ground improvement work or if the soil is contaminated, the costs for their removal may be deducted from the land price, potentially leading to a decrease in land value. Land is an important asset for individuals and corporations. Ground improvement work is crucial for supporting buildings, but it may impact the value of the land in the future. Recently, more people are considering future removal when conducting ground improvement work. *For more details, you can view the related links. Please feel free to contact us for more information.*
