Around the world, there are landfills located in every city in every country. However, due to the complexity and hazardous nature of waste types, landfill waste must be considered impermeable and impermeable to contaminants. Waste includes domestic and industrial waste, which contains a large number of harmful substances and pollutants. We must prevent these harmful substances from escaping and causing serious soil contamination, air pollution or water pollution. Therefore, all landfills must use geotechnical materials to form an impermeable system, which ensures that the waste does not sink and break down and that harmful substances do not contaminate the environment. All these measures are designed to protect the soil and the environment, which is very important for production, living, and environmental protection.
