FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular to a floor covering, in particular, to a membrane intended for separating a screed from a floor covering, and to a production method for producing said membrane. Separating membrane made of plastic material and formed from a convex waterproof sheet that mates with a layer of permeable base; the protuberances are of a cylindrical type with two diameters and are characterized by such a shape and arrangement as to have signs of improved adhesion on both face surfaces.
EFFECT: technical result of the invention is to increase the seizure of the adhesive in order to obtain a greater tensile strength during tearing on the upper front surface and an increase in the contact surface area with the base layer to provide greater delamination resistance on the lower front surface.
