Abstract: The paper introduced a series of amphiphilic CW Epoxy Resin Chemical Grouting Materials which comprise reactivity surfactants, low viscosity epoxy resin as basic agent, and non  toxic, highly tough curing agent which can be solidified in water. The material is featured by low initial viscosity, long operational time, adjustable gel time, good permeability and high mechanical strength. The successful application of this material in concrete crack repair, the consolidation grouting in fault zone, and anti-seepage grouting at the foundation of corrosion zone manifested that the percolation and consolidation of crushed rock zone and silted intercalation could be resolved by CW Epoxy Resin Chemical Grouting. It provides a new approach of improving rock foundation treatment and concrete crack reparation. The key technology of this material is to increase the permeability and infiltration capacity of grouting while ensuring the high strength of its solidity. The permeability and infiltration of the grouting depends not only on viscosity but also on the affinity and surface tension. It is mainly hydrophobic yet also hydrophilic.
