Jiangsu Zhengyan Inspection possesses mature ecological barrier seepage detection technology and equipment. This system was jointly developed by Jiangsu Zhengyan Inspection and the Institute of Environmental Science based on the "Technical Code for Leak Detection of Seepage and Damage of Waste Landfill Liners" (CJJ/T214-2016), tailored to the current situation of seepage and damage in China's waste landfills. The main equipment components are imported from Europe. After years of experimental testing and debugging, a mature seepage detection system technology solution has been formed. This system features high detection sensitivity, accurate positioning, rapid speed, and stable performance. It has been serving multiple domestic landfills and solid waste landfill projects.
