Grouting is used as a repair method in dams, powerplants, tunnels and similar structures subject to ground water pressure. In these applications speed has not been important because it is used in response To damage due to long timeframe disruptions such as soil consolidation, minor seismic activity, and water table changes. By altering Grout system design (component mixing methods, grout machinery Delivery rates, distribution piping, etc.8 it may be possible to Develop high speed methods suitable for remedial repairs that could be required in a deep based weapon system due to short timeframe Disruption caused by weapon detonation. This proposal is to investigate the feasibility of such an approach.
