New GSI test method for resistance of conductive geosynthetics
June 1st, 2022
The Geosynthetic Institute (GSI) has a new test method for resistance measured across positions on conductive geosynthetics. Conductive geosynthetics contain an electrically charged backing (usually a thin layer of polyolefin with letdowns containing 20%–30% carbon black) that allows leaks to be detected in lined systems without the need for a conductive subgrade beneath the liner […]
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, […]
