Construction water flow dynamics of the leak detection layer

April 1st, 2020

By Abigail Gilson-Beck and Larry Shilling The double-lined containment facility featuring a leak detection system (LDS) is the most accurate way of assessing leakage through a primary geomembrane (Bonaparte and Gross 1992). This type of system also represents the gold standard for environmental protection, since leakage through the primary liner is collected and removed so […]

To the editor: Efforts toward achieving zero leaks in a waste containment system (“Achieving Zero Leaks on a Budget” in the June/July issue of Geosynthetics) are certainly laudable. Authors Gilson-Beck and Toepfer do a good job of explaining how electrical leak detection surveys can minimize leaks in a geomembrane liner system at the end of […]

Achieving zero leaks on a budget with geomembranes

June 1st, 2017

For more than 30 years, the geomembrane industry has been told that “all geomembranes leak” (Giroud 1984), as if this were some foregone conclusion no matter what might happen from geomembrane manufacturing to the time it is put into service. But recently, the idea of “zero leaks” has been a hot topic at industry conferences, […]

Are zero leaks with installed geomembranes possible?

June 1st, 2017

Abigail Gilson-Beck and Glen Toepfer step into a geosynthetics minefield in this issue of Geosynthetics with their article “Achieving zero leaks on a budget,” a goal that is controversial in the industry. Whether this goal should even be an objective is the question the debate hinges on. A spirited discussion on this issue arose during […]
