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 […]
2018 State of the Geosynthetics Industry
April 1st, 2018
The U.S. and Canadian geosynthetics market includes geotextiles, geomembranes, geogrids, geosynthetic clay liners, drainage materials, geocells and erosion control materials. In 2017 the U.S. and Canadian geosynthetics market grew in the low single-digit ranges, and it is expected to grow slightly higher in 2018. Consolidation in the geosynthetics market Due to the weaker U.S. dollar […]
