The aim of this paper is to investigate the behavior of geomembranes exposed to hydrostatic puncture, comparing the resistance of different geomembranes and looking at possible correlation with simple tests. Nine commonly used polymer geomembranes were submitted to hydrostatic puncture test, static puncture test and bi-axial tensile test. Hydrostatic puncture tests results showed significant differences in both resistance to puncturing and rupture mode. Influence of the polymer type and thickness of the geomembrane are discussed. Static puncture test and bi-axial tensile test results are found to be correlated with hydrostatic puncture resistance. These tests could be used to predict both behavior and resistance of geomembrane submitted to hydrostatic puncture.
