Multi-linear drainage geocomposites for railways
June 1st, 2022
FIGURE 1 Multi-linear drainage geocomposite under railway embankment In civil engineering, drainage systems are traditionally made with granular material layers and perforated collector pipes. The use of drainage geocomposites became more common 30 years ago with the development of products that met the specific requirements of each application. Moreover, the geocomposite is cheaper than the […]

Profitable geosynthetics companies in 2022?
February 1st, 2022
Before the New Year, in October and November 2021, the first two in-person geosynthetics industry events since the pandemic began took place: the Geosynthetic Materials Association (GMA) fall Lobby Day in Washington, D.C., and GeoNashville 2021. Both were well attended, and many participants were energized by the opportunity to meet with colleagues face-to-face for the […]
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 […]
