As global populations increase, the world’s municipalities are inevitably struggling with the disposal of waste. Over the last few decades, we have seen engineers design numerous containment systems using geomembranes as barriers. Since traditional liners, such as concrete, asphalt, as well as compacted clay soils, are less efficient in the prevention of fluid migration into subsurface soils, the use of geomembranes has exponentially increased since the early 1980s. Municipal Solid Waste landfills (MSW) now usually require a single and/or double composite liner comprised of both a leachate collection and removal system, as well as a geomembrane (overlying either a GCL or compacted clay soil). Supported by the emergence of more stringent environmental regulations around the world, Solmax geomembranes have been extensively used to line landfills as they offer long term durability as well as excellent chemical resistance to a wide variety of harsh materials.
