The invention provides a composition for improving the water repellency of a substrate, like a construction substrate for example a building component. This composition contains a mixture formed by combining: water, at least one water-repellent silicon-containing compound, which is a silicone resin, an alkoxysilane or a polysiloxane, a siloxane surfactant containing an alkylpoly(ethyleneoxy)siloxane group and an alkyl siloxane group, where the alkyl group contains 1-6 carbon atoms. The composition can be used on previous treated substrates or more generally on substrates which are difficult to wet or penetrate. Cette invention concerne une composition permettant d'améliorer la capacité d'un substrat à repousser l'eau, comme un substrat de construction, par exemple un composant d'édifice. Cette composition contient un mélange formé en associant les composants suivants : de l'eau, au moins un composé hydrofuge renfermant du silicium, qui est une résine de silicone, un alcoxysilane ou un polysiloxane, un tensioactif à base de siloxane contenant un groupe alkylpoly(éthylèneoxy)siloxane et un groupe alkylsiloxane, le groupe alkyle contenant de 1 à 6 atomes de carbone. La composition peut être utilisée sur des substrats préalablement traités ou plus généralement sur des substrats difficiles à mouiller ou à pénétrer.
