WAYS OF CREATING IMPERVIOUS GEOCOMPOSITE COATING Russian patent published in 2017 - IPC E02B3/16 

FIELD: construction.

SUBSTANCE: method for creating a geocomposite impervious coating includes preparing a foundation bed, covering it with a waterproof geomembrane, consisting of interconnected sealed sheets of polymeric material, and adding a protective layer made of geotextile material. To eliminate intensive lateral filtering along the contact between the geotextile and the geomembrane, geotextile material is made with polymer edges in the form of cells. The thickness of the geomembrane impervious element, the need for using protective linings of geotextile and the assessment of permeability in the presence of the hole is determined with us of calculated dependences.

EFFECT: invention provides solid impervious protection of hydraulic structures in the foundation, and prevents contact filtration along the contour of geomembranes and geotextiles.
