Double Lining Systems: One and One Can Make Three!

摘要

Double geomembrane lining systems have been used since 1974. That first geomembrane was made with two differentrnmaterials, but since that time the same materials for each liner has become the norm. Thus the synergism of combiningrnthe best of different materials and of cancelling the disadvantages of each are not taken advantage of, thereby notrnachieving the maximum available performance of the superior double lining system. In this paper it is proposed we reintroducernthe beneficial philosophy of using two different materials for the primary and secondary geomembranes ofrndouble lining systems, much like geomembranes and GCLs are combined to generate a better performing compositernliner.
