1. Method for the depth reconstruction of buildings reinforced with structural steel, whereby the damaged concrete is bored to behind the corroded reinforcement, characterised in that the solution of an alkali silicate with an Me2 O : SiO2 ratio of 1:2 to 1:3 is pressed in through the bore under pressure and thereafter a cement/water wash with alkali silicate solution or a mortar mixture, which contains 2 to 6% by weight, relative to the proportion of cement, of a finely divided amorphous silicic acid containing at least 90% by weight SiO2 or finely divided, precipitated, active silicates of magnesium, calcium, barium or aluminium with a BET surface area of 50 to 200 m**2 /g and a d50 % value of under 20 mu m, is pressed in under pressure.
