Interview: Koerner on Lifetime Predictions for Geosynthetics

By Chris Kelsey (

Dr. Russell Jones, President of the International Geosynthetics Society, sat down with the Geosynthetic Institute‘s Dr. Robert Koerner to discuss GSI’s 12-year study on the long-term performance and aging of geotextiles and geomembranes, with a focus on the applicability of the research for lifetime predictions.

Koerner delivered one of the four keynote addresses at GeoAmericas 2016. His topic, “Lifetime Predictions of Exposed Geotextiles and Geomembranes,” resonated well with the conference audience. It also addressed one of the most important and most frequently asked questions: How long will these materials last?

As the field of geosynthetics advances into 40+ year records of in-service projects, the continuing revelations from research such as GSI has conducted add significant support. The long-term performance predictions of the past are proving accurate, and newer research both underscores that longevity as well as establishes stronger confidence and more detailed factors for evaluation and monitoring.
