GSI hosts webinar on geosynthetic drainage materials
February 8th, 2018
The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Geosynthetic Drainage Materials: Applications, Design, Installation and Performance,” on Feb. 24, 2018, from 11:30 a.m. to 1 p.m. EDT. Geosynthetic drainage materials consist of a drainage core (geonet or geospacer) with geotextiles bonded to one or both surfaces. Their in-plane flow capacity is equivalent to 12 […]
HUESKER’s Zerhouni discusses geosynthetic asphalt reinforcement in video
February 2nd, 2018
HUESKER has released a video of Mourad Zerhouni, Dipl.-Ing., who is based in Gescher, Germany, providing an introduction to the functions of geosynthetic asphalt reinforcement. Society’s growing mobility and rapidly aging road networks are currently challenging the road construction sector with ever greater and more cost-intensive options, HUESKER said. Engineers and project managers need to […]

Evaluation of geosynthetic anchor systems through pullout testing
February 1st, 2018
Anchor systems are a vital portion of any erosion control program tasked with negating the effects of erosive forces on disturbed soils. Anchor systems are typically deployed in situations where a rolled erosion control product (RECP) is to be used as the primary erosion control measure. As more RECPs, especially high-performance turf reinforcement mats (HPTRMs), […]
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 […]
GMA fall Lobby Day
February 1st, 2018
GMA’s fall Lobby Day marked the end of an excellent year of meetings on Capitol Hill, 22 with the U.S. Senate and 31 with the U.S. House of Representatives. In recent years, Congress has advocated for geosynthetics in major legislation, such as the Water Resources Development Act (WRDA), the Water Infrastructure Improvement for the Nation […]
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 […]
U.S. representatives pen letter encouraging use of geosynthetics
February 1st, 2018
On Nov. 17, 2017, 10 members of the U.S. House of Representatives sent a letter to Secretary of Transportation Elaine Chao encouraging the U.S. Department of Transportation (USDOT) to consider including the benefits of geosynthetic materials in future infrastructure legislation. “Geosynthetic materials are a critical, innovative element of the transportation construction industry,” the representatives wrote, […]
Erosion control at a former nuclear testing site
February 1st, 2018
A reclaimed 175-acre section within the larger Rocky Flats National Wildlife Refuge in Jefferson County, Colorado, west of Denver, was home to a nuclear testing facility for 40 years. The area’s combination of rolling topography, high winds and incidents of heavy rain and snow increase the likelihood of soil erosion. Given the site’s past use, […]
GSI hosts webinar on wave management in geomembranes
January 31st, 2018
The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Wave (or Wrinkle) Management for Proper Deployment of Geomembranes,” on Feb. 14, 2018, from 11:30 a.m. to 1 p.m. EDT. An intrinsic property of all exposed geomembranes is that they expand and contract depending upon ambient temperature. During times of elevated temperature, waves (also called wrinkles) […]
