Cement-based permeable crystalline waterproofing material for cement concrete structures, permeable crystalline type.

Cement-based capillary crystalline waterproof coating is a rigid waterproof material used for cement concrete. The active chemicals it contains use water as a carrier to penetrate the concrete, reacting with cement hydration products to form water-insoluble needle-like crystals that fill capillary pores and micro-cracks, thereby enhancing the density and waterproofness of the concrete.

From the product definition, cement-based capillary crystalline waterproof coating has two distinctive performance advantages:

1. Beyond the surface, penetrating deep into the substrate

Ordinary waterproof coatings create a waterproof membrane on the surface of the substrate to achieve waterproofing. Once this membrane is damaged, the waterproofing capability is lost. In contrast, cement-based capillary crystalline waterproof coating uses its active substances, with water as a carrier, to penetrate deep into the concrete, react with cement hydrates to form crystals, filling and blocking cracks to provide permanent waterproofing.

Active substances are the main factor affecting the performance of cement-based capillary crystalline waterproof coating. Only when active substances are added in sufficient quantities can they penetrate deep into the substrate, form an adequate amount of crystals, and fill and block cracks, achieving waterproofing and seepage prevention without relying on a surface waterproof layer.
