• Sommario/riassunto: Geomembranes are flexible polymeric sheets which are used as relatively impermeable liners to contain liquid and vapour. With uses ranging from canal liners to hazard waste landfills, they are used extensively in a range of industries such as water conservation, mining, construction and waste management. A Guide to Polymeric Geomembranes: A Practical Approach offers an informed overview of the developments in this field and includes:Detailed discussion of the major geomembrane typesManufacturing methodsKey performance propertiesIndustrial applicationsTesting and
