Provided is a low-temperature-curable cross-section repair material which can be cured in a short period of time, even in extremely low temperature environments of -25°C, and which exhibits excellent workability and strength development. Also provided is a cross-section repairing method using the same. The low-temperature-curable cross-section repair material is characterized by: comprising 100 parts by of a radical polymerizable resin composition (A), 0.1-10 parts by of a hydroxyl group-containing aromatic tertiary amine (C-1), 0.1-10 parts by of an organic peroxide (D), and 1.0-500 parts by of an inorganic filler (E); and the radical polymerizable resin composition (A) comprising at least one type of radical polymerizable resin (A-1) selected from the group consisting of vinyl ester resins, urethane (meth)acrylate resins and polyester (meth)acrylate resins, and a radical polymerizable unsaturated monomer (A-2) having at least two or more (meth)acryloyl groups per molecule thereof.
