DESIGN APPROACHES FOR GROUTING OF ROCK FRACTURES;

Dam structures founded on rock also need to be sealed, and in both cases, this is widely done by rock mass grouting Rock grouting is a cost and time consuming process and design improvements should give direct positive effects of these works This research aims at verifying the socalled ”Real Time Grouting Control Method” (RTGC method)
