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 […]

Oregon State University research reveals railroad ballast performance improvement using GEOWEB geocells
January 25th, 2022
By Katie Bocskor, Manager, Marketing, Presto Geosystems Oregon State University (OSU) recently performed state-of-the-art, three-dimensional dynamic finite element modeling to analyze the reinforcing benefit of Presto Geosystems’ GEOWEB geocells in railway ballast applications. Completed in cooperation with the University of Kansas (KU), which simultaneously put in motion a testing program of geocell-reinforced ballast placed over weak […]
Presto releases geocell ballast research
June 1st, 2018
Presto Geosystems, manufacturer of the high-density polyurethane (HDPE) GEOWEB® geocell base stabilization system, has released results from railroad-track research performed to quantify the reinforcement benefit of GEOWEB-confined ballast as compared to unconfined ballast. The company said the research was a cooperative effort under the direction of Ben Leshchinsky, Ph.D., P.E., of Oregon State University, and […]
