The essential features of epoxy grouting technique comprising diagnosing causes of cracks and selection of suitable epoxy grout system.
If cracks is due to the bond stress failure of concrete we found during diagnosing. Reason behind this crack is lower bond strength of concrete then the requirement. In this case the aim of water tightness and restoration of lost tensile strength of concrete cannot fulfill by providing epoxy grouting because harden epoxy material inside the crack behave as reinforcement and it will crack near by layer of harden cement pest during further loading.
According to my opinion, We have to identify the method of improving bond strength of concrete, reduce the loading on concrete and sandwich the concrete element with higher grade of concrete with required thickness.
