Dr. Fixit Polyplus CP Admix is a waterproofing admixture composed of cement, ultra-fine silica aggregates and proprietary reactive agents and additives used as a permanently active waterproofing treatment for concrete. The chemical ingredients along with the by-products of cement hydration react with the moisture in fresh concrete to generate an incredibly dense crystalline structure which forms an impervious barrier to liquids thereby protecting the concrete and steel reinforcement.
