Achieving zero leaks on a budget with geomembranes

June 1, 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, …

Protecting geomembranes from animal damage

Resisting animal and insect attacks on geomembranes is an interesting problem. Geomembrane installers and manufacturers have had numerous geomembranes damaged by bears, deer, coyotes, birds, beavers, and ground squirrels (Figures 1 and 2). In most cases, the damage is incidental to something else the animal is seeking. Deer damage the liner with their hooves trying …
