Performance/Durability of Polyurea Containment Liners versus Polyethylene Based Geomembranes
In this study the durability and large scale puncture performance of state of the art polyurea geomembranes is tested and compared to various polyethylene materials. The truncated cone test (Large Scale Hydrostatic Puncture, ASTM D5514) was used to determine a critical cone height (CCH) for a 60 mil polyurea liner, a 60 mil HDPE liner, and a 30 mil LLDPE liner; a comparison was also made to CCH values previously published. The results of the study confirm previous findings that more flexible and elastic materials require greater cone heights to induce a puncture as compared to less flexible materials. Polyurea behaves more elastically than any of the previously studied polyethylene materials and possesses a greater CCH.
