Composición y procedimiento para el tratamiento de hormigón y mamposteria
A method of treating the fabric of a building to prevent the ingress of water involves drilling a number of cavities into the relevant area of the building. Thereafter the cavities are filled with a thixotropic paste comprising at least one silane compound, at least one siloxane compound and a thickening agent, all in a water base. The silane compound is preferably an alkyl alkoxy silane such as iso-octyl triexthoxy silane. The silane compound or compounds may be mixed with oligomers having 3 to 8 siloxane units and carrying alkoxy residues. A second siloxane may be present in the form of a modified polymethyl siloxane, preferably as a solvent free water emulsion containing 50 per cent by weight of the polymethyl siloxane. The thickening agent is preferably a modified bentonite. Thixotropic pastes are described for use in the method of treating buildings and also methods of making a such pastes.
