PODCAST: Bob Mackey on the State of Geosynthetics Education

A few years ago, the International Geosynthetics Society revived its Educate the Educators program. The initiative was developed in the early 1990s to help educate engineers, regulators, and academics about geosynthetic materials, which were flourishing in field use. More than 20 years later, the field of geosynthetics had grown enormously—but how to engineer with these materials had not become st... »

PODCAST: Perspectives on Puncture Protection for Landfill Lining Systems

The field of geosynthetics has often been defined by how these materials improve the performance and economics of a particular site or application. One of the ways that geosynthetics achieve such goals is through rigorous testing to ensure proper selection of a material. However, engineering approaches are often driven by a market’s level of infrastructure development and regulatory readiness. Thi... »

PODCAST: Zornberg on Differing MSE Design Frameworks

Mechanically stabilized earth walls have been the subject of the most read stories on Geosynthetica this year and a few of the most read stories in 2016 as well. This past spring, some of that field interest in MSE design became the focus of a unique meeting at the Geotechnical Frontiers 2017 conference. There, the ASCE Geo-Institute Technical Committee on Geosynthetics brought together leading MS... »

PODCAST: George Koerner on Exposed Geomembrane Performance

George Koerner, Director of the Geosynthetic Institute, had the honor this year of delivering the first Koerner Lecture—a series named in honor of his father Dr. Robert Koerner, who is internationally recognized as one of the godfathers of geosynthetics and who continues his work as Director Emeritus at GSI. Last year, I had the pleasure to see both Koerners at an ASCE’s GeoChicago conference and ... »

PODCAST: Pullout Anchor Testing in Erosion and Sediment Control

Jay Sprague of the South Carolina-based Denver Down Research Facility took on a private client’s pullout anchor testing questions with erosion and sediment control systems and components. The results began to yield revealing data on anchor pullout performance, and in a way that has not been previously explored. Listen to “Pullout Anchor Testing in Erosion and Sediment Control” on Sprea... »

Defining Interaction Flexibility for Geogrid-Reinforced Structures

By HUESKER – Key properties in effective geosynthetic reinforcement are adequate tensile stiffness and tensile strength coupled with good interaction behavior. The relatively new technical term interaction flexibility introduces a previously disregarded aspect: the flexibility of the geogrid in a reinforced structure. This property has been shown to improve the interaction between soils and the ge... »
