FIELD: hydraulic engineering, repair of high arch and gravity concrete dams. SUBSTANCE: technology of section by section injection provides for temporarily omitted sections in which additional opening of cracks and/or contact seams takes place for some time within permissible value near upper face of dam while adjacent sections are injected. This approach makes it feasible to fill cracks and/or seams opened in omitted section in this manner under relatively low pressure which prevents opening of cracks and/or contact seams in adjacent sections already injected with concrete and eliminates need in repeat injection. EFFECT: eliminated need in repeat injection of concrete. 2 cl, 4 dwg
