Geomembranes are often used in civil engineering applications to create a hydraulic barrier. Their basic function is to remain impervious over the entire design life of the project. However, mechanical stresses induced by confined materials could produce a deformation of the membrane and in critical situations, could ultimately puncture it. This paper will describe the design-related approach for protection layers and explain the concept of the test. Results will be presented, where different geotextile types were tested and the testing conditions were changed. Overall this paper will give a closer insight of this design-oriented test method.
