We would like to introduce a case where the high water content soil improvement agent "MT Series" was used in pile construction. In a condominium construction project in Tokyo, cement-containing mud generated during friction pile construction was improved with "MT-2" and immediately transported to a temporary storage area on site. Additionally, during the construction of a drainage pumping station, mud generated during pile driving using the middle trench pile method was improved with "MT-2" and immediately transported to a temporary storage area. [Case Summary] - Cement-containing mud generated during friction pile construction was improved with "MT-2" and immediately transported to a temporary storage area on site. - Mud generated during pile driving using the middle trench pile method was improved with "MT-2" and immediately transported to a temporary storage area. *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of using the high water content soil improvement agent "MT Series" in shield construction and thrust construction. During a torrential downpour, in the construction of a storage pipe to prevent flooding in urban areas, excess muddy water generated from the mud pressure shield method was removed from the site using our product in combination with a cement-based solidifying agent. Additionally, in the construction of burying power pipes from a mega-solar facility to an industrial park, excess muddy water generated from the mud slurry thrust method was improved with "MT-1" and immediately transported to an intermediate treatment facility. [Case Summary] ■ Excess muddy water generated from the mud pressure shield method was removed from the site using our product in combination with a cement-based solidifying agent. ■ Excess muddy water generated from the mud slurry thrust method was improved with "MT-1" and immediately transported to an intermediate treatment facility. *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of using the high-water-content mud soil improvement agent "MT Series" in river improvement works and port dredging works. In the construction work to dredge sediment accumulated in rivers and secure river capacity, the dredged sediment was improved with "MT-2" and immediately transported to a temporary storage site about 10 km away. Additionally, in the construction work to dredge sediment accumulated in a fishing port, the mud dredged by a grab dredger was improved with "MT-3" and immediately transported to a temporary storage site about 22 km away. 【Case Overview】 ■ Dredged sediment improved with "MT-2" and immediately transported to a temporary storage site about 10 km away. ■ Mud dredged by a grab dredger improved with "MT-3" and immediately transported to a temporary storage site about 22 km away. *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of using the high water content soil improvement agent "MT Series" in dam construction and pond renovation projects. In the construction of bridge piers for a detour road associated with new dam construction, the sediment accumulated in the dam was improved with "MT-2" and immediately transported to a temporary storage site several kilometers away. Additionally, in the construction of the embankment and water intake facilities for the pond, the mud accumulated in the pond was improved with "MT-1" and immediately transported to a sediment disposal site approximately 10 kilometers away. [Case Summary] - Improved sediment accumulated in the dam with "MT-2" and immediately transported to a temporary storage site several kilometers away. - Improved mud accumulated in the pond with "MT-1" and immediately transported to a sediment disposal site approximately 10 kilometers away. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the applicable soils and features of our high-water-content soil improvement agent, the "MT Series." After adding this product and mixing for about 15 minutes with a backhoe, the mud is modified into a plastic state and can be immediately transported by dump truck. It can be applied to river and harbor dredged soil, sediment from reservoirs, excavated soil from construction sites, excess mud and water from thrusting and shielding, mud from pile driving, and mud generated from heavy rain disasters. 【Features】 ■ Immediately transportable ■ Environmentally friendly ■ Reduces CO2 emissions ■ Can be modified at room temperature ■ Can be used in conjunction with solidifying agents *For more details, please download the PDF or feel free to contact us.

The "MT Series" is a high-water-content mud improvement agent that can quickly solidify mud and easily transport it. After adding this product, mixing with a backhoe for about 15 minutes will modify the mud into a plastic state, making it immediately transportable by dump truck. Additionally, compared to transporting mud with cement or lime, it can reduce CO2 emissions by about 90%, and it can modify mud with a very small addition amount of about 1 to 8 kg/m3. [Use Cases] - Dam construction and pond renovation - River improvement and harbor dredging - Shield construction and thrusting work - Piling work *For more details, please refer to the PDF materials or feel free to contact us.

The "Bontelan Method" is a construction technique that actively reuses soil that has traditionally been deemed unsuitable for embankment by mixing fiber-based soil improvement material "Bonfiber" and a solidifying agent into the soil. This method transforms the soil into a high-performance ground material. The high-performance ground materials enhance handling properties, add functions such as high durability, erosion resistance, and liquefaction countermeasures. We take pride in our construction achievements, totaling 630,000 m³ and 400 projects. [Features] - Improved handling properties (contributing to disaster recovery) - Simple construction machinery for improvement - High-performance ground materials such as erosion resistance, durability against repeated wet and dry conditions, and liquefaction countermeasures - Non-decomposing Bonfiber *For more details, please download the PDF or feel free to contact us.
