Webinar: Effect of Subgrade Conditions on Geosynthetic Clay Liner Hydration and Performance



Geosynthetics Technical Webinar Series: Part 1: Barriers 13 May 2020 

The performance of a Geosynthetic Clay Liner (GCL) and a Composite Liner depends on many parameters. The first component is the GCL subgrade. Most of the time, this important part is missing or underestimating in designs and specifications. This geosynthetics technical webinar series for barriers starts from the first important component which is the subgrade. The webinar shares the latest international and local updates and research findings including design considerations and latest discussion from International Geosynthetics Society (IGS) Technical workshop 2020 on barriers in Barcelona.
