Geomembrane Behavior In Mining Explored In Webinar

Learn about the effects of acidic and alkali conditions on geomembrane performance in mining solutions at an upcoming webinar this month.

The IGS Technical Committee on Barriers (TC-B) is set to host Dr. Fady B. Abdelaal, who will talk about ‘Long-term performance of different polymeric geomembranes in extreme high and low pH mining solutions’.

Dr. Abdelaal will explore the behavior of HDPE, LLDPE, and blended geomembranes under these extraordinary conditions. The data presented includes up to six years’ immersion in the laboratory to provide estimates of the geomembrane performance at field temperatures.

Dr. Abdelaal’s expertise in Geoenvironmental Engineering involves testing and characterization of polymeric and bituminous geosynthetic barrier systems for waste containment facilities to examine their long-term degradation behavior.

As assistant Professor in the Department of Civil Engineering at Queen’s University, Kingston, Canada, his research program involves the use of geosynthetics in municipal solid waste landfills, low level radioactive waste containment facilities, potable water reservoirs and mining applications. He is also leading a research project to monitor the long-term performance of geosynthetic liners in frozen ground.

The talk is the latest in a series of monthly TC-B webinars focused on specific technical aspects of geosynthetic barriers.


Dr. Abdelaal’s lecture takes place live on May 26 at 9pm EST. To join, please register here. You can check the webinar date and time relevant to your time zone at registration. The webinar will be repeated for different time zones so if you cannot attend the main webinar simply register and select the encore session and you will be contacted by the TC-B with more details.
