Dual effect of Sikkaton SAN
One of its components closes off the macroscopic pores and cracks in the masonry structure of the wall and another diffuses in all directions around the hole. The activating chemicals react with water and the free ions contained in the wall itself. This generates water-repellent crystalline formations that plug the pores, capillaries and fine cracks in the walls and prepare capillaries to become water-repellent. This creates an impenetrable barrier to the capillary action responsible for introducing moisture into the wall. The mortar penetrates into cracks and hollows in the wall where it solidifies and replaces the portion of the wall removed by drilling. The strength of the structure and the air permeability of the wall itself is unchanged after injection.
