● Cement-based permeable crystalline waterproof material is a gray powdery material formulated with ordinary Portland cement as the base material and mixed with active chemical components. Cement-based permeable crystalline waterproof material, its waterproof mechanism is mainly porous. Under the action of water, the waterproof material contains active chemical substances, using water as a carrier. As water penetrates into the pores of the structure, the active chemical substances The water penetrates into the interior and reacts to form insoluble crystals such as ettringite. The active chemical substance and the unhydrated cement particles undergo a hydration reaction, and promote the cement hydration, forming cement hydration crystals, generating a large number of crystal filling, sealing The pores are blocked so that water cannot enter the concrete, thereby achieving the purpose of waterproofing.
● Cement-based permeable crystalline waterproof material, due to its good adhesion, whether it is a light base surface and a wool base surface, a back water surface and a water facing surface, a dry base surface and a wet base surface, or a stagnant water base surface does not affect its construction effect .
