EVOH Layers and Better Gas Barrier Performance for Geomembranes

On by Geosynthetica
News and Articles

Geosynthetic barriers perform exceptionally well in liquid containment applications, but gas barrier performance can still be improved. Volatile organic compounds, for example, can diffuse through barrier systems. The rate is low, but the incorporation of an EVOH layer in a geomembrane has shown that the diffusion rate of VOCs can actually be much lower. Applications that utilize geosynthetics and... »

News and Articles

Ethylene Vinyl Alcohol (EVOH) has been a promising addition to geomembrane manufacturing options. A thin EVOH layer has the capability to reduce dramatically the permeability of membranes to gases of all kinds and provide to the geomembrane excellent gas barrier characteristics. This enhances their environmental and functional benefits far beyond any existing solution. But, as with most innovation... »
