Generally, geomembranes are covered because of the nature of their application or to protect them from damage.rnThey have, however, been used in exposed applications such as roofs, drainage channels, and landfill covers withrnfavorable results for years. In addition to the challenges of exposure to ultraviolet light and potential damage from thernelements, exposed geomembrane covers (EGCs) also have the unique challenges of foundation settlement, gasrngeneration pressure, and sheer size, which present difficulties with securing against wind load, shedding stormwater,rnand access. This paper presents some of the ways these challenges have been overcome in actual applications.
