FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering, in particular to the impervious geotextile coating of low-pressure earth dam. Dam coating comprises cellular structure made of polymer material. Cellular structure is attached on the cloth of waterproof geotextile material. Cellular structure has variable depth, which increases gradually from the crest to foot of the dam. Cells of structure are filled with soil.
EFFECT: reduction of water loss for seepage.
