The waterproofing effect of cement-based penetrating crystalline waterproof coating comes from the chemical interaction between the various active chemical components it contains and the micro-moment structures in the concrete under the guidance of water. With the help of the osmotic pressure of water, it enters the capillary zone of the concrete, and its various chemical agents mix and react to form crystals, which seal the capillary tubes and shrinkage cracks and drive away the water. This reaction can occur on either the front or back surface of the concrete structure.
