Geosynthetics in agriculture
December 19th, 2022
Hydroponics represent a growth opportunity for geosynthetics and are becoming increasingly popular, especially in urban areas. Here, a hydroponics farm designed by Hydronov LLC incorporates a Viaflex Dura-Skrim® R12BV geosynthetic liner supplied by International Cover Systems (ICS). Such liners help contain the water that feeds the systems. Photo: Hydronov LLC The list of concerns hitting […]

Koerner Award and Lecture Series. This momentous occasion will create a unique opportunity for attendees at the Geosynthetics Conference 2023. Start making plans now […]
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 […]

New GSI method for strain hardening of HDPE geomembranes
April 1st, 2022
Traditionally, high-density polyethylene (HDPE) geomembranes are checked for stress crack resistance using the ASTM D5397 single point-notched constant tensile load (SP-NCTL) test (Hsuan, Lord and Koerner [1990]). This test uses notched specimens, surfactant, and elevated temperatures to accelerate the behavior and force a brittle failure in HDPE geomembranes. With today’s high stress crack resistant HDPE […]
