FIELD: construction.
SUBSTANCE: method to develop an antifiltration barrier, which prevents descending migration of hydrophobic contaminants in soils, both in the form of a separate liquid phase and also in the form of an aqueous solution, includes formation of a liquid capillary screen and arranged below the sorption barrier. Natural mineral and/or organic sorbents with high water-retention properties are applied into the upper layer of soil, with subsequent moistening of soil medium to a condition of field water capacity. When forming a sorption barrier, an activated carbon is used.
EFFECT: increased efficiency of retention of liquid and water-dissolved hydrocarbon contaminants, preservation of water-physical properties of soil, increased environmental safety, reduced material intensity.
