In the area of waste management, the geomembrane is used in waterproofing landfills for hazardous and non-hazardous waste, leachate ponds and landfill cover. It prevents soil, water and air contamination from waste decomposition.
The HDPE geomembrane is used at the base of landfills and leachate ponds. Its low permeability, excellent chemical and mechanical resistance, resistance against biological attacks and excellent resistance to the sun's rays make it the best option for this application. When stability is a critical factor, the embossed textured geomembrane is indicated because its structured and constant texture provides reproducible friction angle values and high friction values.
For landfill covering, the LLDPE geomembrane presents the necessary flexibility coupled with the same advantages of the HDPE geomembrane
