The method of repairing cracked wall structure is designed especially for antique buildings. The method consists in filling the crack through a surface closure with quick-hardening mass, followed by injection of a binding agent under pressure. Characterized in that: A grid of openings (D), alternating on both sides along the crack, is drilled after filling the crack in. The openings should be inclined towards the crack at the angle (α), preferably higher than 45°. The depth of the openings should not be smaller than the dimension, which guarantees the length (l2) of the opening up to the point of crossing the crack is at least equal to the length (l1) up to this point, and not larger than the length limited by the (x) thick zone on the opposite side of the wall, while (x) is about 5 cm. Then, the concrete-steel rods (5) are introduced into the openings (D), which are closed with injection terminals (3) and a mixture of epoxy resins (6) is injected.
