FIELD: protection of underground structures against corrosion. SUBSTANCE: method locating points of corrosion carbonate cracking consists in measurement of potentials relative to several comparison electrodes placed at distance 2.0-10.0 m, without disconnection of polarization source. Points of corrosion carbonate cracking are sections having greater absolute value of potential or greater potential difference as compared with adjacent sections. EFFECT: simplified approach and accelerated location of points of corrosion carbonate cracking. 1 dwg, 1 tbl
