Avoiding Whales in Anaerobic Digesters

By Ian D. Peggs, P.E. – In 2014, shortly after being placed in service, one of two geomembrane-lined and covered anaerobic digesters generated extensive whales—“bubbles” in the lining system. Attempts to remove the apparent gas from under the cover were made unsuccessfully until it was realized that the cover was being uplifted by gas under the liner. Within two or three days, there were whales se... »

Solmax Geomembranes - Additive Packages, Resins, Performance

Additive Packages, Resins, and Geomembrane Performance

How do additive packages, resins, HPOIT and OIT testing, and other components and quality control measures to geomembranes affect material durability and performance? Solmax engineer Mathieu Cornellier led a webinar on these topics earlier this month. The company has posted the presentation on its YouTube Channel. Cornellier focuses on polyethylene (PE) geomembranes, including high-density (HDPE) ... »

Geosynthetics in India

IGS India Ready for GeoAsia 6 in New Delhi

Nearly 20 years ago, the GeoAsia conference series kicked off with an International Geosynthetics Society (IGS) conference in Bangalore. The event was hosted by IGS India. In 2016, GeoAsia 6 will bring the event back to India. The theme for GeoAsia 6 is “Geosynthetics for Infrastructure Development.” Roads, hydraulic structures, reinforcement, ground improvement, and geosynthetics test... »

Cartegena 2016 - VIII CICES

Cartagena 2016: Changing Infrastructure, Changing Soils

Changing infrastructure changes soils, and our responses to the geotechnical challenges of our soils—the solutions we choose—determine the sustainability and long-term economics and successful performance of our infrastructure. This is a central point to Cartagena 2016. This 8th Iberoamerican Congress on Erosion and Sediment Control (VIII CICES – Cartagena 2016) will be held 15 – 17 August 2016 an... »
