Aqueous solution in nanotechnologies  of particular siloxane derivatives  specific for deep and water repellent impregnation against capillary rising damp in neutral alkaline high and medium porosity building materials. The nanometer diameter of its particles allows the product to penetrate inside the support with a depth so far impossible to reach with common traditional system.

The particular low viscosity  formulation guarantees an optimal penetration of the resin inside the wall fabric  up to the smallest pores. The support, after catalyzing the resin, assumes a  high water repellency  such as to determine the interruption of the capillary rise of the water molecules.
