Water-alcohol solution for the creation of hydrophobic chemical barriers, prepared with specific siloxane derivates. The specific blend of conveyance of the active ingredient guarantees the utmost penetration and diffusion of the product within damp walls, allowing it to penetrate the substrate in a more uniform manner than with traditional standard systems in emulsion or gel form, thus rendering even the smallest pores hydrophobic and interrupting widespread rising damp. The product is free of water-soluble materials and chemical products that are harmful to the materials in the masonry. It does not alter the breathability of the surface and offers complete chemical inertia. The product is supplied in a kit with HYDRO SACCA, for gravity application with specific system.

HYDRO BARRIER is suitable for application on any brick, masonry, stone or mixed walls, as long as they are free of cavities or gaps, that require the reduction of widespread rising damp. HYDRO BARRIER can be used on walls that are due to be plastered, in combination with the dehumidifying system DRY RIN and DRY SOFT or DRY IDRO, or on exposed masonry, without altering the colour of the wall.
