A punch test method has been developed to assess the performance of shotcrete and membranes. Each sample is sprayed onto a rock substrate containing a loading disc. The sample is rotated 180 degrees, placed onto the sample frame and constrained on all sides. The loading disc is displaced at a constant rate by the screw feed jack which in turn loads the sample. Instrumentation is used to measure the load being applied to the sample through the loading disc and the displacements that occur. The testing method is described in detail. Results from a number of different materials is presented and discusse.
