EVOH Layers and Better Gas Barrier Performance for Geomembranes

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... »

By Ian D. Peggs – On 21 March 2016, I-CORP will celebrate 25 years of geosynthetics consulting, with particular emphasis on geomembranes, pipes, and other engineered plastic components and materials. In January 1991, I left Geosyntec/Geoservices in Florida to develop a geosynthetics division with Greg Richardson at ENSCI in High Point, North Carolina. That division, however, was shut down in March... »
