Use of chemicals for foundation treatment and sealing of crack is of recent origin. The aim of this paper is to find time-viscosity and time-strength relationships of epoxy grout system for proper flow mechanism and strength interaction with rock collected from dam sites of India. The bonding mechanism of gel in the injected mass is explained with the help of Scanning electron microscopy and Infra-red spectroscopy. After trial field grouting the stratascopy has revealed better bonds of moist surface with flexibility to accommodate movement before bond or shear failure occurred and had lower volumetric shrinkage during curing
