Available in liquid and powder form, Aquafin-IC Admix crystalline waterproofing admixture is added to the concrete either during the batching process or at the construction site to the ready-mix truck. The admixture works through a chemical reaction within the concrete matrix. In the presence of water, the ingredients react with free lime and other by-products of cement hydration to form non-soluble crystals that fill and plug the pores and capillaries of the concrete matrix, making the concrete waterproof. As long as water is present the reaction will continue for the life of the structure. Aquafin Inc. www.aquafin.net
