Geosynthetics opportunities and solutions in shale gas extraction
October 1st, 2018
While natural gas contained within shale rock is geologic and thus ancient by its very nature, the practice of its removal by horizontal drilling coupled with hydrofracking is a relatively recent development (Figure 1). Indeed, these dual technologies are making possible the recovery of huge amounts of natural gas—so much so that one can envision […]
Geosynthetics and coal combustion residuals
October 1st, 2018
According to the World Bank Group, in 2015 coal produced 41% of the world’s energy and about 34% of the energy production in the United States. While global warming and pollution are serious challenges according to most scientific evidence, and coal burning is cited as one cause of both, there are many staunch advocates of […]

GSI to host webinar on geotextile tubes
June 11th, 2018
The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Applications and Design of Geotextile Tubes,” on Wednesday, June 13, 2018, from 11:30 a.m. to 1 p.m. EDT. Geotextile tubes are large factory-fabricated textile tubes with multiple access ports for introduction of infilled material, which is usually dredged and in slurry form. After an overview, a […]
HUESKER releases video on SoilTain geotextile tubes for dewatering
April 26th, 2018
HUESKER Group made public a YouTube video on the company’s SoilTain geotextile tubes for high-flow dewatering of waterlogged sediments and residues from mines, industrial plants, construction sites and sewage works, applications, the company said, that are often expensive and labor intensive if dewatering is not undertaken. The SoilTain dewatering tube is a technical textile containment […]

Editorial: Geomembranes and water
April 1st, 2018
The World Health Organization (WHO) asserts that a clean water supply is “fundamental to global health.” WHO estimates that considerable exposure worldwide to contraction of many waterborne diseases and conditions (diarrhea, malaria, malnutrition, parasites, bacterial infections, etc.) could be diminished by increasing access to safe drinking water, improving sanitation and hygiene, and improving water management. […]
Riverbank erosion protection using engineered geosynthetics in Mexico
February 1st, 2018
The Río La Antigua is a river that flows through a low-lying region in the Mexican state of Veracruz, which has the historical importance of being one of the first regions where Hernán Cortés landed in the early 1500s. The Casa de Cortés is a popular tourist attraction, and the village of La Antigua’s economy […]
Geosynthetics and erosion control
February 1st, 2018
Terra firma often does not morph in ways that modern society appreciates. Erosion from stormwater, snowmelt, long-term water flow and unrelenting waves sweep away soil and rock from steep slopes, riverbanks, ditches, channels, shorelines, building foundations and much more. To understand the power of erosion, simply think about the Grand Canyon, which was formed by […]
