The resin composition of the present invention is used to form a surface layer that covers at least a part of the outer surface of particles filled in cracks formed in the underground layer, and an acid curing agent having an acidic group, It contains an acid curable resin that is cured in the presence of an acid and polyester, and the acid curing agent is present in a state where the acidic group is blocked by a compound having reactivity with the acidic group. ing. Thereby, a resin composition that can reliably cure the acid curable resin at a target location, an injection containing the resin composition and particles, and a filling that fills cracks formed in the ground with the particles A method can be provided. |
