The resin composition according to the present invention can be used for forming a surface layer that covers at least a part of the outer surface of each of the particles (2), comprises an acid curing agent and an acid-curable resin capable of being cured in the presence of an acid, wherein the acid curing agent exists in such a state that an acidic group in the acid curing agent is blocked by a compound that is reactive with the acidic group. Thus, it becomes possible to provide: a resin composition having such a property that an acid-curable resin contained therein can be cured reliably at a desired point; a grouting agent comprising the resin composition and particles; and a filling method for filling the particles in cracks formed in the ground.
