Controlling uplifting gas bubbles in exposed geomembrane-lined ponds—Part 3
April 1st, 2018
Part 1 of this series (Thiel 2017) demonstrated how the size, shape, pressure, and stresses and strains experienced by geomembrane bubbles inflated with gas could be analytically estimated. Part 2 of this series (Thiel 2018) evaluated the considerations for incorporating a gas-venting underdrain below the geomembrane liner. The current, and final, Part 3 of this […]
Protecting geomembranes from animal damage
June 1st, 2017
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 […]
Geomembrane waterproofing for a 10-mile wooden flume
