Geomembrane: An Environmental Barrier and Core for Pollution Control in Landfills
Release time:
2026-01-15
Landfills, as a crucial link in urban solid waste treatment, face significant challenges in environmental governance due to leachate leakage causing soil and groundwater pollution. Geomembranes, as the core seepage control material for landfills, serve as an "environmental barrier" to prevent pollution spread, thanks to their superior seepage control performance, acid and alkali corrosion resistance, and long-term stability.

This product is made from high-density polyethylene (HDPE) and other high-quality raw materials using advanced blow molding or calendering processes. It has an extremely low permeability coefficient, effectively preventing heavy metals, organic matter, and other harmful substances in leachate from seeping into groundwater and soil. Simultaneously, it possesses excellent tensile strength, elongation at break, and puncture resistance, adapting to the complex geological conditions and subsequent settlement deformation of landfills, ensuring the long-term stable operation of the seepage control system.
In landfill construction, geomembranes are widely used in key areas such as the bottom, slopes, and closure covers of the landfill area, forming a complete composite seepage control system in conjunction with geotextiles, drainage layers, and other materials. Not only can it cut off pollution pathways at the source and reduce environmental governance costs, it also helps landfills achieve compliant operation, aligning with the environmental protection concept that "lucid waters and lush mountains are invaluable assets."
With the continuous improvement of environmental standards, geomembranes have undergone continuous iterations in material formulation and production processes, becoming more environmentally friendly, durable, and efficient. This provides reliable technical support for the ecological management of landfills, making it an indispensable key material for urban ecological protection.
