Present paper presents the application of pressure grouting in hydraulic tunnels subjected to high internal pressure of water. Structural analysis of the pressure grouting used for pre-stressing of concrete lining is shown along with the methods used to control the pressure grouting effects. The paper also presents a new experimental method for measuring the loss of water along the complete tunnel under operating conditions and a mathematical model for the evaluation of tunnel impermeability and functionality. All presented test methods have been developed and all measurements were performed by the ¡°Jaroslav Cerni¡± Institute for Development of Water Resources in Belgrade (Serbia). These methods are presented on the example of a hydraulic tunnel of the ¡°Bajina Basta¡± pumped storage plant in Serbia, during the stages of its construction and operation.
