Dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer.

WHY?
Factory fabrication reduces field welding, reduces installation time and costs, allows modular construction and provides consistent seam and liner quality.

FGI Offering Webinar on Airport Reinforced Soil Slope Failure

Yeager Airport RSS Failure Case History - Thursday, August 20, 2020 at 11 a.m. CDT

Construction of this 67 meter high reinforced soil slope (RSS) was completed in December 2006. After seven years in-service, a tension crack was observed at the top of the slope. In March 2015 this RSS structure catastrophically collapsed. This RSS structure collapsed in a compound failure mode; as the failure plane passed beneath, partially behind, and partially through the reinforced soil mass. The RSS collapse occurred after 8.3 years in-service as the shear strength along the shale-claystone foundation interface decreased and approached the fully softened strength. This webinar will cover the forensic investigation performed, the causes of the failure and lessons learned.
