Geomembranes are very low permeability membrane liners and barriers used with any geotechnical engineering based material so as to control fluid migration in a man-made project, structure or system. 2, record 2, English, - geomembrane

Geomembrane : The term liner applies when a geomembrane is used as an interface or a surface revetment. The term barrier is usually reserved for the cases where the geomembrane is used inside an earth mass. Geomembrane is a generic term which has been proposed to replace many terms such as : synthetic membranes, polymeric membranes, plastic liners, flexible membrane liners, impermeable membranes and impervious sheets. These terms are not appropriate because :(i) synthetic, polymeric and plastic are too restrictive;(ii) geomembranes are not always used as liners;(iii) flexible membrane is redundant; and(iv) no material is absolutely impermeable or impervious. In addition, many users for these materials habitually designate them with trade names, which adds to the terminology confusion. Geomembranes should not be confused with other similar membranes used for such applications as single-ply roofing, floating covers and air supported roof. Also, geomembranes should not be confused with geotextiles [which are permeable by construction]. 2, record 2, English, - geomembrane

As a groundwater pollution control mechanism, the use of a liner on the bottom and sides of a landfill has been considered necessary for many years. This necessity is created by the moisture in the landfill materials (augmented by rainfall and snowmelt) interacting with the contained waste, forming a liquid called "leachate". ... The types of liners that have been used are ... numerous ... but the predominant liner material until recently has been clay ....
