Shorten the time for dredged soil treatment! A soil improvement agent that enables dump transportation.

In the harbor industry, there is a demand for the rapid processing of mud and soil resulting from dredging work. It is particularly important to quickly remove the soil after dredging to prevent delays in construction. Traditional processing methods pose challenges due to time and cost. Our high-water-content soil improvement agent, the MT series, allows for the rapid improvement of dredged soil, enabling immediate removal by dump trucks. [Usage Scenarios] - After dredging the mud accumulated in rivers, we want to remove it immediately from the site. [Benefits of Implementation] - Instant solidification of the soil, allowing for immediate removal by dump trucks. - Reduction of construction time.

Applications/Examples of results

Examples of Dredging Work in Dam Lakes Client: Ministry of Land, Infrastructure, Transport and Tourism Project Overview: In the dam that supplies water for daily use, there were concerns about the effects of alkalinity when improving the dredged soil, making it impossible to use cement or lime. Therefore, the neutral and highly safe MT-2 was adopted, and after improving the dredged soil with this product, it was immediately transported to a temporary storage site located several kilometers away. Examples of Slurry Shield Tunneling Work Client: Private Sector Project Overview: The surplus slurry generated from the slurry shield tunneling method was initially planned to be transported to an intermediate treatment facility by vacuum trucks, but the transportation costs were relatively high. As a result, the surplus slurry was improved using MT-1 and immediately transported by dump trucks, leading to significant cost savings compared to the original transportation method. Examples of Port Dredging Work Client: Miyagi Prefecture Project Overview: The site was very narrow, requiring the dredged soil to be transported by dump trucks, but securing working space was difficult. Therefore, MT-3 was adopted, and after improving the dredged soil on-site, it was immediately transported to a temporary storage site located about 5.0 km away.

Line up（3）

Model number	overview
MT-1 (Standard Soil Type)	【Package】15kg/poly bag 【Properties】White powder 【Standard Addition Amount】Approximately 2 to 8kg/m3 【Features】Absorbs moisture in the soil and improves its dry texture. Improvement can be achieved with light mixing as the reaction begins the moment it comes into contact with the soil. 【Applicable Soil Types】Excess slurry from shield tunneling, river dredging soil, sediment from reservoirs, water treatment generated soil, disaster-generated sediment, various construction sludge.
MT-2 (Standard Soil and Cement Slurry Compatible Type)	【Package】15kg/poly bag 【Form】Gray powder 【Standard Addition Amount】Approximately 1-5kg/m3 【Features】Absorbs moisture in the soil and improves viscosity, enhancing a chewy texture. It is effective as the dissolved components entangle with soil particles, so thorough mixing is necessary. It has been treated to suppress dust generation, reducing dispersion even in windy sites. 【Applicable Soil Types】Excess slurry from shield tunneling, river dredging soil, sediment from ponds, water purification byproducts, disaster-generated soil, various construction sludge, ground improvement sludge.
MT-3 (Marine Clay Compatible Type)	【Package】18kg/poly bag 【Form】Gray powder 【Standard addition amount】Approximately 1 to 5 kg/m3 【Features】Improves the viscosity of soil and enhances its chewy properties. The dissolved components exert their effects by entangling with soil particles, so thorough mixing is necessary. It has been treated to suppress dust generation, reducing scattering even in windy conditions. Primarily a product for seawater mud. 【Applicable soil types】Port dredged soil, various types of mud containing seawater.
