The MT series high moisture content soil stabilizer quickly solidifies high moisture content soil generated at construction sites, enabling immediate removal by dump trucks. Traditionally, high moisture content soil was solidified with cement or lime before being removed, requiring a large amount of solidifying agent and a specified curing period to achieve strength. Thus, we developed the MT series high moisture content soil stabilizer, which can modify the soil quickly with a small amount of additive. 【Features】 ■ Removable in a short time ■ Excellent ease of use ■ Effective with low additive amounts ■ Does not adhere to heavy machinery ■ Can be used in conjunction with cement *For more details, please refer to the PDF document or feel free to contact us.

<Overview of the Technology> The Bontelan method is a technology that repurposes bottom sediment accumulated in agricultural ponds or excavation soil from embankments, which are traditionally deemed unsuitable for use as fill, into high-performance ground materials for the renovation and reinforcement of embankments. <Purpose and Objectives of Development> Renovation of agricultural pond embankments requires high-quality soil with excellent strength and impermeability; however, it has become difficult to obtain such soil around these ponds. On the other hand, these ponds often have thick layers of bottom sediment, which contribute to a reduction in water storage capacity and deterioration of water quality, thereby hindering or degrading the functionality of the ponds. Bottom sediment typically contains a high proportion of clay and silt, and due to its generally high water content, it is not easy to dispose of. Therefore, there has been a demand for technology that actively repurposes this sediment into ground materials from environmental and economic perspectives. In response, we developed the Bontelan method by mixing fiber-based soil improvement materials called "Bonfiber" and solidifying agents into the bottom sediment of agricultural ponds, thereby adding functions such as excellent strength characteristics, high seismic resistance, and high durability. There was no earthquake damage to all embankment fill and pond embankment soil constructed using this method prior to the earthquake, and it was selected as one of six technologies recognized for their effectiveness during the Great East Japan Earthquake from a total of 165 submissions at the 2011 Construction Technology Forum.

This construction project involves dredging the sediment from a reservoir. At the same site, the accumulation of sediment in the reservoir had reduced its water storage capacity, causing issues. However, the high moisture content of the sediment made it difficult to transport using dump trucks. Therefore, a high moisture content sediment improvement agent, MT-2, which is neutral and allows for immediate transport from the site, was adopted. The original sediment was improved with this product, and after primary transportation within the site using a crawler dump truck, the treated soil was transported to a temporary storage area several kilometers away using dump trucks. *For more details, please refer to the PDF document or feel free to contact us.*

• Turbid water and muddy water treatment machines

We would like to introduce a case study of the high water content soil improvement agent MT series. This project involves the restoration of a gas pipe buried underground. When we excavated the shaft, groundwater emerged at depths of 10 to 30 meters, causing mud and muddy water to hinder the construction. Additionally, the temporary storage yard was narrow, requiring immediate removal of the mud. As a solution, MT-1 was adopted, and this product was added to the mud mixed with quality soil for improvement. The improved soil was promptly transported to an improvement plant located about 15 kilometers away. The main objective of this project was the restoration of the gas pipe, and there were concerns about the time and cost involved in removing the mud. The high water content soil improvement agent MT series provides reliable support for unexpected mud situations. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce examples of the construction of the high-cement-content soil improvement agent MT series. This work involves creating improved soil using a self-propelled soil improvement machine. Until now, the challenge has been that high-water-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 could 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 was also confirmed that adding MT-2 did not affect the strength development of the improved soil. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of the MT series high cement content soil improvement agent. This project involves the construction of a tunnel in an urban area using the NATM method. The wash water from the ready-mix concrete trucks used on site contained slurry and needed to be regularly transported off-site. However, the site was narrow, and it was difficult to secure a vacuum truck for an extended period. Therefore, MT-2 was adopted due to its characteristics of low additive amount and immediate transport capability. After improving the mud with this product, it was transported to the designated disposal site via a standard 10-ton dump truck, passing through public roads.

This construction project involves the removal of sediment accumulated in the retention basin. The site is located near residential areas, and due to the limited construction space, it was difficult to use cement or lime for improvement. Therefore, a high-water-content soil improvement agent, MT-1, was adopted, and after improvement with this product, the material was immediately transported by dump truck to a nearby temporary storage area. *For more details, please refer to the PDF document or feel free to contact us.*

• Agricultural civil engineering works

This construction project is a land readjustment project aimed at the large-scale consolidation of rice paddies. In this project, the initial plan was to backfill the existing waterway with locally generated soil for agricultural use. However, due to the high moisture content of the locally generated soil, we considered methods for soil improvement, but using cement or lime was not feasible due to concerns about their impact on crops. Therefore, we conducted trial mixtures to see if the high-water-content clay soil improvement agent MT-2 could be used. As a result, all soil environmental standard component analysis items were below the standard values, and the soil hardness (Yamanaka method) was determined to be 12mm after 21 days, leading us to conclude that backfilling with improved soil was possible, and we proceeded with mixing at the site of the existing waterway. Furthermore, considering future subsurface drainage and agricultural practices, the use of improved soil was limited to a depth of 80cm below the surface. Subsequently, improved soil was also utilized in adjacent construction projects. *For more details, please refer to the PDF document or feel free to contact us.*

• Agricultural civil engineering works

This construction project involves the removal of treated water sludge that has been discharged onto the solar drying bed at the water purification plant. At the same purification plant, due to heavy rain, the turbidity of the dam that serves as the water source increased, leading to a rise in the amount of treated water sludge discharged onto the solar drying bed, which posed a risk of the treatment cycle falling behind. Therefore, to urgently remove the treated water sludge from the solar drying bed, a high-water-content mud modifier, MT-1, was adopted, and after being modified with this product, it was immediately transported to a temporary storage area on-site. *For more details, please refer to the PDF document or feel free to contact us.*
