    KLJ ? -V is a concrete waterproofing admixture. The admixture is blended into the concrete mixture during the batching process in order to waterproof and protect concrete right from the beginning. It can perforate the cement paste and concrete capillary pores, forming crystalline or gelatinous substances which fill the capillary pores and in doing so reduce concrete permeability. Capillary Crystalline Waterproofing Agent is widely utilized in tunnel and subway systems, hydropower stations, reservoirs, underground vaults and pre-cast components.
