GCLs and a Flood Dam Monitoring System

By NAUE – The need to mitigate the impact of flooding has intensified as floods have become more frequent and serious. All types of dams are being reassessed. Their “impermeability” during emergencies, which is deeply connected to their integrity and overall safety, is of paramount importance. But how can these structures be monitored for better assurance of performance? NAUE was invol... »

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... »

CQA Solutions - Cable Ties and Geosynthetics

How Cable Ties Can Cost a Geosynthetics Project Millions

Construction quality assurance expert Glen Toepfer (CQA Solutions) takes on the topic of cable ties in his latest video post from his Uncontained blog. In the 3.5-minute video, he shares notes from the field, including the impact of geonet yield, thermal expansion, safety, and testing speed. “Not a lot of attention seems to be paid to them in the specifications,” he says. “How ma... »
