Geomembrane Spark Testing and Difficult Installation Points

"When asked what voltage setting was used to perform spark testing on a pipe penetration weld the operator said “Dunno, I just turned it to the max as stated in the instructions”! This is just the right way to miss leaks, as happened..." Ian Peggs of I-CORP INTERNATIONAL takes a look at what is occurring during spark testing. »

Landfill Design, Simplified

David D'Souza, writing for the Goa, India-based Herald, discusses modern, double-lined landfill design but in plain language. He explains the importance of geosynthetic systems, including drainage and containment, and he does it all with easily understandable comparisons, such as geomembrane liners and bathtubs. His succinctly answered questions and plain language demonstrate one way engineers mig... »
