Performance benefits of factory-fabricated geomembrane liners

March 4, 2020

Geomembranes are meant to provide a practically impermeable barrier for large-scale containment of liquids and gasses. Therefore, geomembrane liners are manufactured for the lowest possible permeability, depending on the application and chemicals involved. However, the amount of seam welding, patching, and other fieldwork that is carried out during their installation
