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... »
