The paper focuses on seal defect of dam system of an impoundment with deposition of calcareous sludge. The seal defect of the impoundment dam system, consisting of a homogeneous ground dam, occurred due to its underflow by desludged water. This paper lists causes of the underflow at the dam system, based on analysis of the original engineering-geologic survey, construction method of the dam body, floating method at the impoundment and additional engineering-geologic survey. The primary cause of the defect is presence of permeable zone in the subsoil. Secondary causes were failure to follow certain recommendations of the original engineering-geologic survey and incorrect presumptions of the deposition of floated sediments at the impoundment. The analysis of causes of the seal defect in the impoundment dam system was the basis for proposed remediation measures carried out in two stages. Stage I of the remediation was construction of principal spillway of the impoundment?s accumulation area and supplementing of drainage system of the dam body. For the stage II remediation measures, a sealing underground wall was constructed in order to seal the permeable layer in subsoil. After completion of both stages of remediation works, tightness of the dam system was re-established.
