Seven-Layer EVOH-Based Liner
Megaplast USA Inc.
Primary applications for this barrier geomembrane with an EVOH core for 0% permeability are landfill caps, vapor barriers in building construction, and floating covers. Other features include stronger tensile properties through changes in the chemical composition of the geomembrane, yield elongations that are double of standard GM13 allowing for fabrication of longer based products where the films are under constant duress, reduced expansion/contraction in the field, and a more consistent nitrogen texture with better control in asperity height translating to a more consistent friction in the field with the subgrade/geosynthetic clay liner composites.
