Henan Tuhua Shi Environmental Protection Building Materials Co., Ltd. is a high-tech enterprise with soil solidifier as its core, committed to building an engineering comprehensive service system integrating soil solidification technology research and development, application design, product production, and professional construction.Henan Tuhua Shi Environmental Protection Building Materials Co., Ltd. is a high-tech enterprise with soil solidifier as its core. The company is committed to the research and development, application design, product production, and professional construction of soil solidifier as an integrated engineering comprehensive service system. Before its establishment, the company was an engineering company that responded to the national environmental protection call. In 2011, it introduced "soil solidifier" from abroad and applied it to engineering construction, solidifying different soils. In 2015, the company focused on researching the application of soil solidification technology in urban and rural road construction, and conducted in-depth research on various roads such as municipal roads, heavy-duty roads, and temporary environmental protection roads. In 2017, we independently developed the fourth generation of biocatalyst soil stabilizer and obtained national invention patents for its core technology through extensive market validation.In recent years, with the increasing requirements of the country for roads, traditional construction techniques cannot meet market demand. The non renewable materials such as lime and sand in traditional road subgrade materials are limited by environmental protection and raw materials. The market urgently needs subgrade treatment materials that can meet engineering needs. The fourth generation soil stabilizer developed by our company can replace traditional building materials such as lime, cement, fly ash, crushed stone, and gravel. It is a non-toxic, harmless, non corrosive, non polluting, and non combustible high concentration soil stabilizer that is beneficial for ecological environment protection and can save costs. The economic and environmental benefits are particularly significant, and it is also an innovative scientific technology for the sustainable development of road engineering. It has unique soil solidification effects and wide practicality, and has been widely used in the construction of road base and sub base, water conservancy slope protection and other engineering projects.
