Cement-based Permeable Crystalline Waterproofing coating is powdery inorganic waterproof material which is made of the base materials of special cement and silica sand mixed with various active chemical materials.

Its waterproofing mechanism is: Brush the material on the surface of concrete base course, and after it contacts water, under the action of water, the active substance in it will permeate into the concrete inside and react with the concrete and generate the water-insoluble dendritic crystal, which is filled in the capillary channel and micro crack of the concrete, so as to make the concrete more compact and play a role of permanent resistance of water and seepage.
