By Dr. Robert M. Koerner – Since 2001, the Geosynthetic Institute has accumulated data on failures of geosynthetic-reinforced mechanically stabilized earth (MSE) retaining walls. Our MSE wall failures database presently has 301 cases, of which 191 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our past writings and webinars... »

Drs. Robert and George Koerner of the Geosynthetic Institute (GSI) are no strangers to tackling challenging topics—subjects which are either difficult to motivate discussion on (e.g., failures) or difficult to document (e.g., developing and monitoring long-term studies). One of the information-sharing vehicles they’ve utilized over the years to keep information flowing has been to release influent... »

In 2004, Geosynthetica’s Director Elizabeth Peggs, Lara Costa, and founder Dr. Ian D. Peggs, P.E. (I-CORP International) created a white paper that proposed a Geosynthetics Risk Management and Loss Control Program (GRMP). Targeting insurers of construction projects, the program aimed to establish the need for expert design review to prevent costly failures that might result from improper use... »
