The emulsion comprises: 1) at least one resin M alpha D beta T gamma Q delta (OR) epsilon (I) where: M=R<1>R<2>R<3>SiO1/2, D1 = R<4>R<5>SiO2/2 T = R<6>SiO3/2 Q = SiO4/2; 2) the reaction product between: 2a) one or several aromatic amines or polyfunctional aliphatics from 2 to 25 carbon atoms; 2b) one or several carboxylic acids or anhydrides containing 3 to 22 carbon atoms; 2c) at least one cross-linking agent which is a water-soluble metal complex. The invention is useful for waterproofing surfaces, in particular building materials paricularly stone, cement, concrete, mortar, bricks, tiles, wood, in which the above emulsion is used. |
