Geomembrane liner has been widely accepted as standard components of geosynthetic lining systems in many containment facilities. Among the plastic materials utilized for geomembranes, high density polyethylene (HDPE) geomembranes are the most widely used geosynthetic lining materials adopted for various containments applications including solid waste landfill, liquid containment and reservoirs, mining, etc. This is mainly attributed to its superior hydraulic and mechanical properties in combination with its very low permeable characteristics, greater chemical resistance and ultraviolet (UV) light degradation resistances. HDPE geomembranes serve as very low permeability barriers to stop or limit the migration of liquids and/or chemicals out of the containment area. The paper presents the application of impervious HDPE geomembrane adopted in an industrial brine lagoon and a chemical solution pond of a mine site in Northern China and Mongolia at elevation altitude 2,600m and 1,600m, respectively. HDPE geomembrane with exceptional flexibility and outstanding mechanical properties and high durability provides an effective and economical solution as liquid containment and leakage prevention to the chemical pond. This paper also discusses the characteristic of the High Density Polyethylene (HDPE) geomembrane as waterproofing elements. Lastly, geomembrane installation under the extreme environment and related issues are discussed.
