Studies Show how Geocells Improve Seismic Reduction Factors of Retention Walls

D. Leshchinsky (et al) testing of PRS geocell earth retention walls at the National Seismic Research Institute in Japan concluded that geocells can be used successfully for walls even under very high seismic loads (reduction factor of 0.3 – 0.4). The studies noted that geocells made from HDPE are unsuitable for long-term applications, and guidelines were given to PRS to further its development of its Neoloy based Geocell for demanding applications requiring long-term performance.
