FIELD: construction engineering. SUBSTANCE: according to method, maintenance of moistened brickwork is effected by injecting paraffin which acts as barrier for liquid. Used as collecting vessel for liquid paraffin is heated reservoir operating on principle of sucking due to rarefaction. Owing to such kind of operation, liquid paraffin is not flowing out from blind holes made in brickwork for injecting paraffin. Due to simultaneous heating of paraffin in blind hole it is possible in addition to do away with preliminary drying of moistened brickwork. EFFECT: higher efficiency. 2 cl, 1 dwg
