basic information
【Product Lineup Features】 <Calcium-based Solidification Material "TN-1"> ■ Lime + Hemihydrate Gypsum + Treated Sewage Sludge ■ Widely used as a solidification material suitable for improved soil production in improved soil plants, etc. ■ Can also be used for soil improvement work on site ■ The solidification material alone is weakly alkaline and neutralizes quickly <Cement-based Solidification Material "TN-2"> ■ Cement + Hemihydrate Gypsum + Treated Sewage Sludge ■ Can be widely used as a solidification material suitable for soil improvement work at construction sites ■ Suitable for neutral zone soil improvement due to the main raw material being recycled material (hemihydrate gypsum) <Hemihydrate Gypsum Solidification Material "TN-3"> ■ Hemihydrate Gypsum + Treated Sewage Sludge ■ The combination of hemihydrate gypsum and treated sewage sludge suppresses fluoride leaching ■ Hardening is completed early due to the hydration reaction of hemihydrate gypsum ■ Utilizing the property of rapidly absorbing moisture and solidifying, it can be used in various applications such as construction sites and sludge treatment facilities <Hemihydrate Gypsum "TN-P"> ■ Strengthens sludge-like soil from riverbed excavation to a cone index of 200 kN/m² or more, making it transportable by dump trucks ■ Can solidify muddy soil from rivers and be used for various applications *For more details, please refer to the PDF document or feel free to contact us.

Company information
In recent years, awareness of environmental conservation and recycling has been increasing and becoming established. I believe that it is the responsibility of humans living in nature to protect natural resources and the environment—soil, water, and air—that are indispensable to daily life, as shared assets of the entire region and ultimately the entire planet. Tanaka Construction Co., Ltd. aims to contribute to local environmental conservation by developing, manufacturing, and selling recycling products that are beneficial for environmental preservation as a company that deals with "soil." As specialists in "soil," we want to contribute to the formation of a regional circular society by upholding the mottos: "No unnecessary 'soil' will be produced!" "Actively recycle usable 'soil'!" "Create high value-added 'soil'!" "Environmental regeneration!"
