Electrical leak detection at depth
February 1st, 2022
Q: I am taking the opportunity to ask a question about the electrical leak detection (ELD) test for geomembranes: We have the area covered with silt from the past rainy season, and it is estimated to be about 5 feet (1.5 m) deep worst-case scenario. The liners in this area were not properly inspected and […]
ABS geosynthetics product types
February 1st, 2022
Q: Infrequently, I make a note of geosynthetic products manufactured using acrylonitrile butadiene styrene (ABS) (e.g., geogrid, binding line, a few molded specialty products). Can you provide a summary of most of the geosynthetic product types using ABS, as well as the general benefits and limitations of ABS geosynthetics? A: Thank you for your GMA […]
Reinforcement over soft soils with high-strength geogrids
February 1st, 2022
FIGURE 1 Port of Guaymas, Mexico, high-strength geogrid jobsite view Construction over soft foundation soils is usually associated with poor bearing capacity, excessive differential settlements and lateral sliding instability. Furthermore, the presence of poor ground conditions at a construction site is the most frequent cause of long construction durations. There are several alternatives that can […]
Geosynthetics for stabilization in solar farm development
February 1st, 2022
FIGURE 1 Laying down geotextiles at Chicot Solar Energy Center, Chicot County, Ark. With renewed focus on clean electricity, an era with massive investment in new solar power has begun, leading to its widespread development. Although these systems have become more cost-effective, there are often solutions left on the table that could make the costs […]

Geosynthetic Materials Association has been busy (more to come)
February 1st, 2022
Eleven leaders from the geosynthetics industry came together in Washington, D.C., Oct. 19–20, 2021, to participate in the Geosynthetic Materials Association (GMA) fall Lobby Day 2021. During Lobby Day, GMA members advocated for specific language related to geosynthetics in the Infrastructure Investment and Jobs Act (IIJA), then under consideration in the House of Representatives. The […]
Reinforced levees to induce seepage path around geogrid layers?
February 1st, 2022
FIGURE 1 Reinforced levee expansion over existing dike using geosynthetics The Geosynthetic Institute (GSI) has been asked many times regarding several applications for different styles of geogrids if reinforced levees will induce a seepage path adjacent to and around geosynthetic layers. At this point, GSI has no case histories where it can quantify such behavior […]
