Concentrated cream based on silanes formulated for the creation of chemical barriers by injection  into walls against the capillary rise of humidity in natural stone masonry, brick, mixed stone and concrete.

The concentrated gel has excellent diffusion characteristics and forms a chemical barrier  preventing rising humidity from passing through the porosity of the materials that make up the wall. After catalysing the resin, the support becomes  highly water-repellent , resulting in the interruption of the capillary rise of water molecules.

BARRIER GEL counter the formation of salt efflorescences  on the masonry and does not alter the breathability of the support in the slightest.
