Upper Chiquita Reservoir update
October 20th, 2024
Figure 1 Aerial showing the multi-stages of construction of the geocomposite, liner and floating cover This article is a review of the Upper Chiquita Reservoir project originally constructed in 2011 and today remains one of the largest and most challenging potable-water liner and geomembrane floating cover projects installed in the United States. The reservoir liner […]
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 […]
