A geomembrane is a relatively thin, very low permeability synthetic membrane liner or barrier often used in conjunction with natural geotechnical engineering related materials so as to control fluid (or gas) migration in a human-made project, structure or system.
Geomembranes are typically made from polymeric materials and can be generally classified as either
a) un-reinforced, un-supported pure polymer materials such as HDPE (high density polyethylene) or LLDPE (linear low density polyethylene) or
b) reinforced, supported polymer materials that typically feature HDPE core reinforcements with LLDPE outer layers.
Geomembranes can also be made from the impregnation of geotextiles with asphalt, elastomer or polymer sprays, or as multilayered bitumen geocomposites.

Applications for geomembranes include: landfills, mining, hazardous material containment, waste water storage, above ground storage tanks, irrigation, pond, canal, basin and other linings, water flow redirection, aquaculture, potable water containment and many other uses.
Light-weight materials are often used in the oil and gas industry as temporary liners, rain cover applications in areas such as mining and landfills, agricultural crop covers, ground covers, ponds, truck and rail car liners, etc.
