Studies Show how Tough-Cells Improve Seismic Reduction Factors of Retention Walls

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