The magic of water and geosynthetics
February 1st, 2019
Water is a fundamental issue in many projects using geosynthetics. From erosion control to reservoir liners and covers, from landfill leachate pond barriers to coal ash dewatering, handling water and the effects of water are considerations nearly every engineer employing geosynthetics considers. Geosynthetics can effectively manage water applications of erosion control, reinforcement, barriers, filtration and […]
Part 2: The regulation of CCR in the United States: Geosynthetics and barriers
October 1st, 2017
As discussed in Part 1 of “The Regulation of CCR in the United States,” for the first time in decades, nationwide regulation of CCR (coal combustion residuals) surface impoundments expands the regulated use of geosynthetic materials. While the CCR Rule (2015) allows continued operation of existing CCR surface impoundments, it provides criteria for the disposition […]

Part 1: The regulation of CCR in the United States: Geosynthetics and barriers
August 1st, 2017
The regulation of coal ash (coal combustion residuals or CCR) has significantly expanded the market for geosynthetics within the United States. Further, there is interest in these regulations around the globe in every country using coal as an energy source. These regulations are the result of recent environmental incidents. The regulations call for the increased […]
