Patent ID: 7410703

Claim:
A method of producing an impermeable surface lining for buildings, the method comprising fixing, to a building surface, a superposition of layers or of elements comprising, starting from the surface: optionally, at least one layer of adhesion primer; at least one water-impermeable polymeric membrane; optionally, at least one sheet of woven or nonwoven fibrous material; at least one layer of adhesive; at least one external covering; wherein: a. the impermeable membrane is obtained from an aqueous dispersion of silicone oil(s) comprising: -A- 100 parts by weight of at least one organopolysiloxane oil (A) that can crosslink by condensation, if necessary in the presence of a crosslinking agent (B), made of an elastomer, -A′- optionally, up to 30 parts by weight of at least one unreactive organopolysiloxane oil, -B- if necessary, from 0.1 to 100 parts by weight of at least one crosslinking agent (B), -C- optionally, up to 50 parts by weight of at least one adhesion promoter (C), -D- up to 200 parts by dry weight of at least one filler (D), -E- a catalytically effective amount of a catalytic curing compound (E), optionally up to three parts by weight, -F- at least one emulsifier (F), -G- optionally, at least one functional additive (G) and -H- water; b. the adhesive employed includes at least one adhesion promoter (C′); c. the aqueous silicone oil(s) dispersion is applied as a film to the surface; d. the crosslinking of the silicone film then takes place, preferably at room temperature; e. at least one layer of adhesive, to which the adhesion promoter C′ has been added, is then applied, by coating it onto the crosslinked silicone film; and then, finally f. the external covering is laid, wherein the external covering is a tile.
